>

> Description: FIELD OF THE INVENTION

> [0001] This invention pertains to a method for killing house dust

mites

> in soft materials such as clothing.

> BACKGROUND OF THE INVENTION

> [0002] It has been known for many years that common house dust is

an

> important cause of asthma, rhinitis and eczema in allergic

individuals.

> The mite Dermatophagoides pteronyssinus and related mites are

the

> major sources of house dust allergen in temperate climates

including the

> United States. Dust mites are eight-legged arachnids, relatives of

> spiders. They live in close association with humans, their main

food

> source being the shed scales from skin. A major protein allergen

present

> in the fecal particles of Dermatophagoides pteronyssinus, Der p

I,

> can cause acute asthma symptoms when present at levels greater than

> 10Î¼g per gram of dust.

>

> [0003] Dust mites are photophobic, and live within soft materials

such

> as pillows, mattresses, blankets and clothing. One study revealed

20,000

> live dust mites in a jacket. Another study showed mean Der p I

levels

> of 15.9 Î¼g/gm in all clothing and 21.0 Î¼g/gm in woolen garments.

> Hot water washing, dry cleaning, freezing and prolonged sun

exposure can

> kill mites in fabrics. These methods are not practical for all

fabrics,

> or may not be practical to do frequently.

>

> [0004] Since mites are not insects and are not even closely

related to

> insects, it is not surprising that many insecticides do not kill

mites.

> Chemical miticides exist which can kill some types of mites, but

most of

> these have been developed for agricultural use, to kill plant-

eating

> mites which infest growing crops or stored grain, and which

constitute

> different mite species. Use of a chemical substance indoors, and

> particularly on clothing or carpeting in close contact with the

user,

> obviously requires that the chemical be safe and pleasant.

>

> [0005] Despite advances in treatment, morbidity, mortality and

costs

> related to asthma and other allergic diseases continue to rise.

Since

> house dust mites are a major cause of these conditions, there is a

need

> in the art for a safe and effective way of killing mites in

clothing and

> other fabrics.

> SUMMARY OF THE INVENTION

> [0006] The present inventor has found, surprisingly, that exposing

> woolen or other fabrics to the vapors of certain pleasant-smelling

plant

> oils, including wintergreen oil, lavandin oil, Ylang-Ylang oil, and

> others, kills house dust mites in those fabrics.

>

> [0007] In one aspect of the present invention, a method for killing

> house dust mites which are living in or infesting a fabric

substrate is

> disclosed. The method includes the step of exposing said mite-

infested

> substrate to a vapor of at least one plant oil. The plant oil may

be

> selected from the group of Anise, Balsam, Basil, Bay, Birch,

Cajeput,

> Camphor, Caraway, Cinnamon, Clove, Coriander, Dill, Fennell, Fir,

> Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

Peppermint,

> Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja, Thyme,

> Wintergreen and Ylang-Ylang.

>

> [0008] In a preferred method, the exposing step comprises placing

the

> mite-infested substrate in a closed drawer or other closed

container

> along with a volume of the selected plant oil. The plant oil can be

> applied to the substrate in a variety of manners as can be

understood

> from the following detailed description.

>

> [0009] These and other features and aspects of the present

invention can

> be better appreciated from the following description of certain

> preferred embodiments.

> DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTS

> [0010] I discovered that exposing woolen clothing or other soft

fabrics

> infested with house dust mites to the vapors of several plant

> oils—including the oils of Anise, Balsam, Basil, Bay, Birch,

> Cajeput, Camphor, Caraway, Cinnamon, Clove, Coriander, Dill,

Fennell,

> Fir, Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> Peppermint, Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja,

> Thyme, Wintergreen and Ylang-Ylang—kills the mites in such clothing

> as well as their eggs.

>

> [0011] The oils used are aromatherapy-grade oils produced by steam

> distillation of the specific plant, and readily available

commercially

> from many suppliers. These oils release vapors spontaneously, and

thus

> can be placed in contact with the mite infested substrate in many

ways,

> e.g. placing a few drops of the oil on an absorbent material such

as a

> paper towel or piece of cotton, which is then placed in a closed

> container, such as a closed drawer or a sweater storage box,

containing

> the infested fabric. Alternatively, several drops of the oil may be

> placed in a plastic or glass dish within such a closed container.

> Application may also be effected by spraying a mist of the oil

onto the

> substrate by means of a simple atomizer, and then placing the

treated

> object into a sealed container that allows the accumulation of the

oil

> vapor. In the case of substrates which can not be placed within

closed

> containers for treatment, such as carpets, the vapor of the oil

may be

> contained long enough for it to have its desired effect by placing

an

> impermeable barrier such as plastic sheeting over the carpet which

has

> been sprayed with the oil, and leaving such barrier in place for a

> sufficient time to kill mites, such as, for example, 24 hours.

> Additional methods of dispersing the vapor of the oils include the

use

> of a packet containing a solution or gel of the plant oil having

on at

> least one surface of the packet a permeable membrane through which

the

> vapor volatilizes either spontaneously or with the help of electric

> heat, as in an air freshener. All of these methods have proven to

be

> effective.

>

> [0012] The substrates encompassed by the methods of the present

> invention include without limitation clothing, carpeting, bedding

> materials, upholstery, toys made from fabrics, and other soft

fabrics.

>

> [0013] The present invention is further described in the following

> working examples, which are intended to illustrate the invention

without

> limiting its scope.

> EXAMPLE 1

> [0014] The ability of various plant oils to kill house dust mites

was

> assessed by placing three drops of the oil being tested into a

Petri

> dish containing D. pteronyssinus cultures. Cultures were

examined

> microscopically 3, 8, 24 and 48 hours later. It was discovered

that the

> vapor of some oils killed all mites by 8 hours, while others had no

> effect even after 24 hours of exposure. The following table lists

those

> oils found to be capable of killing all of the dust mites (+),

those

> which killed some but not all (+/-), and those which did not kill

> them (-).

> > Claims: What is claimed

is:

> >

> > 1. A method for killing house dust mites infesting a fabric

substrate,

> > said method comprising the step of exposing said mite-infested

substrate

> > to a vapor of at least one plant oil selected from the group

consisting

> > of: Anise, Balsam, Basil, Bay, Birch, Cajeput, Camphor, Caraway,

> > Cinnamon, Clove, Coriander, Dill, Fennell, Fir, Garlic, Lavender,

> > Lavendin, Lemongrass, Marjoram, Nutmeg, Peppermint, Pine,

Rosemary, Rue,

> > Sage, Spearmint, Tea Tree, Thuja, Thyme, Wintergreen and Ylang-

Ylang.

> >

> > 2. The method as in claim 1, wherein the exposing step comprises

placing

> > the mite infested substrate in a closed container along with a

volume of

> > the selected plant oil.

> >

> > 3. The method as in claim 2, wherein the plant oil is saturated

into a

> > piece of cotton or a piece of a toweling.

> >

> > 4. The method as in claim 2, wherein the plant oil resides in an

open

> > dish within the closed container.

> >

> > 5. The method as in claim 1, wherein the exposing step comprises

> > spraying the plant oil on the substrate.

> >

> > 6. The method as in claim 1, wherein the fabric substrate is one

of a

> > clothing, a bedding material, an upholstery, a carpeting, and a

toy made

> > from fabric.

> >

> > Description: FIELD OF THE INVENTION

> > [0001] This invention pertains to a method for killing house

dust mites

> > in soft materials such as clothing.

> > BACKGROUND OF THE INVENTION

> > [0002] It has been known for many years that common house dust

is an

> > important cause of asthma, rhinitis and eczema in allergic

individuals.

> > The mite Dermatophagoides pteronyssinus and related mites are

the

> > major sources of house dust allergen in temperate climates

including the

> > United States. Dust mites are eight-legged arachnids, relatives

of

> > spiders. They live in close association with humans, their main

food

> > source being the shed scales from skin. A major protein allergen

present

> > in the fecal particles of Dermatophagoides pteronyssinus, Der

p I,

> > can cause acute asthma symptoms when present at levels greater

than

> > 10Î¼g per gram of dust.

> >

> > [0003] Dust mites are photophobic, and live within soft

materials such

> > as pillows, mattresses, blankets and clothing. One study

revealed 20,000

> > live dust mites in a jacket. Another study showed mean Der p

I levels

> > of 15.9 Î¼g/gm in all clothing and 21.0 Î¼g/gm in woolen

garments.

> > Hot water washing, dry cleaning, freezing and prolonged sun

exposure can

> > kill mites in fabrics. These methods are not practical for all

fabrics,

> > or may not be practical to do frequently.

> >

> > [0004] Since mites are not insects and are not even closely

related to

> > insects, it is not surprising that many insecticides do not kill

mites.

> > Chemical miticides exist which can kill some types of mites, but

most of

> > these have been developed for agricultural use, to kill plant-

eating

> > mites which infest growing crops or stored grain, and which

constitute

> > different mite species. Use of a chemical substance indoors, and

> > particularly on clothing or carpeting in close contact with the

user,

> > obviously requires that the chemical be safe and pleasant.

> >

> > [0005] Despite advances in treatment, morbidity, mortality and

costs

> > related to asthma and other allergic diseases continue to rise.

Since

> > house dust mites are a major cause of these conditions, there is

a need

> > in the art for a safe and effective way of killing mites in

clothing and

> > other fabrics.

> > SUMMARY OF THE INVENTION

> > [0006] The present inventor has found, surprisingly, that

exposing

> > woolen or other fabrics to the vapors of certain pleasant-

smelling plant

> > oils, including wintergreen oil, lavandin oil, Ylang-Ylang oil,

and

> > others, kills house dust mites in those fabrics.

> >

> > [0007] In one aspect of the present invention, a method for

killing

> > house dust mites which are living in or infesting a fabric

substrate is

> > disclosed. The method includes the step of exposing said mite-

infested

> > substrate to a vapor of at least one plant oil. The plant oil

may be

> > selected from the group of Anise, Balsam, Basil, Bay, Birch,

Cajeput,

> > Camphor, Caraway, Cinnamon, Clove, Coriander, Dill, Fennell, Fir,

> > Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

Peppermint,

> > Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja, Thyme,

> > Wintergreen and Ylang-Ylang.

> >

> > [0008] In a preferred method, the exposing step comprises

placing the

> > mite-infested substrate in a closed drawer or other closed

container

> > along with a volume of the selected plant oil. The plant oil can

be

> > applied to the substrate in a variety of manners as can be

understood

> > from the following detailed description.

> >

> > [0009] These and other features and aspects of the present

invention can

> > be better appreciated from the following description of certain

> > preferred embodiments.

> > DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTS

> > [0010] I discovered that exposing woolen clothing or other soft

fabrics

> > infested with house dust mites to the vapors of several plant

> > oils—including the oils of Anise, Balsam, Basil, Bay, Birch,

> > Cajeput, Camphor, Caraway, Cinnamon, Clove, Coriander, Dill,

Fennell,

> > Fir, Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> > Peppermint, Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree,

Thuja,

> > Thyme, Wintergreen and Ylang-Ylang—kills the mites in such

clothing

> > as well as their eggs.

> >

> > [0011] The oils used are aromatherapy-grade oils produced by

steam

> > distillation of the specific plant, and readily available

commercially

> > from many suppliers. These oils release vapors spontaneously,

and thus

> > can be placed in contact with the mite infested substrate in

many ways,

> > e.g. placing a few drops of the oil on an absorbent material

such as a

> > paper towel or piece of cotton, which is then placed in a closed

> > container, such as a closed drawer or a sweater storage box,

containing

> > the infested fabric. Alternatively, several drops of the oil may

be

> > placed in a plastic or glass dish within such a closed container.

> > Application may also be effected by spraying a mist of the oil

onto the

> > substrate by means of a simple atomizer, and then placing the

treated

> > object into a sealed container that allows the accumulation of

the oil

> > vapor. In the case of substrates which can not be placed within

closed

> > containers for treatment, such as carpets, the vapor of the oil

may be

> > contained long enough for it to have its desired effect by

placing an

> > impermeable barrier such as plastic sheeting over the carpet

which has

> > been sprayed with the oil, and leaving such barrier in place for

a

> > sufficient time to kill mites, such as, for example, 24 hours.

> > Additional methods of dispersing the vapor of the oils include

the use

> > of a packet containing a solution or gel of the plant oil having

on at

> > least one surface of the packet a permeable membrane through

which the

> > vapor volatilizes either spontaneously or with the help of

electric

> > heat, as in an air freshener. All of these methods have proven

to be

> > effective.

> >

> > [0012] The substrates encompassed by the methods of the present

> > invention include without limitation clothing, carpeting, bedding

> > materials, upholstery, toys made from fabrics, and other soft

fabrics.

> >

> > [0013] The present invention is further described in the

following

> > working examples, which are intended to illustrate the invention

without

> > limiting its scope.

> > EXAMPLE 1

> > [0014] The ability of various plant oils to kill house dust

mites was

> > assessed by placing three drops of the oil being tested into a

Petri

> > dish containing D. pteronyssinus cultures. Cultures were

examined

> > microscopically 3, 8, 24 and 48 hours later. It was discovered

that the

> > vapor of some oils killed all mites by 8 hours, while others had

no

> > effect even after 24 hours of exposure. The following table

Thats what I'm saying exactly....the car has not been sprayed with

anything for a long time. The only thing we have used to keep the

car free of critters is menthol crystals. We don't do it everyday,

but that might not be a bad idea in the beginning. Go buy a $4.00

coffee cup warmer from Walgreens, take the metal cup off a tea light

candle, fill the cup with menthol crystals, put the coffee cup warmer

on the driver side seat or floorboard, use a extension cord to the

nearest outlet and let run overnight. If you really want to make it

strong use two tea light cups filled with menthol at the same time

on the coffee cup warmer.

> > > BACKGROUND OF THE INVENTION

> > > [0002] It has been known for many years that common house dust

> is an

> > > important cause of asthma, rhinitis and eczema in allergic

> individuals.

> > > The mite Dermatophagoides pteronyssinus and related mites are

> the

> > > major sources of house dust allergen in temperate climates

> including the

> > > United States. Dust mites are eight-legged arachnids, relatives

> of

> > > spiders. They live in close association with humans, their main

> food

> > > source being the shed scales from skin. A major protein allergen

> present

> > > in the fecal particles of Dermatophagoides pteronyssinus, Der

> p I,

> > > can cause acute asthma symptoms when present at levels greater

> than

> > > 10Î¼g per gram of dust.

> > >

> > > [0003] Dust mites are photophobic, and live within soft

> materials such

> > > as pillows, mattresses, blankets and clothing. One study

> revealed 20,000

> > > live dust mites in a jacket. Another study showed mean Der p

> I levels

> > > of 15.9 Î¼g/gm in all clothing and 21.0 Î¼g/gm in woolen

> garments.

> > > Hot water washing, dry cleaning, freezing and prolonged sun

> exposure can

> > > kill mites in fabrics. These methods are not practical for all

> fabrics,

> > > or may not be practical to do frequently.

> > >

> > > [0004] Since mites are not insects and are not even closely

> related to

> > > insects, it is not surprising that many insecticides do not kill

> mites.

> > > Chemical miticides exist which can kill some types of mites, but

> most of

> > > these have been developed for agricultural use, to kill plant-

> eating

> > > mites which infest growing crops or stored grain, and which

> constitute

> > > different mite species. Use of a chemical substance indoors, and

> > > particularly on clothing or carpeting in close contact with the

> user,

> > > obviously requires that the chemical be safe and pleasant.

> > >

> > > [0005] Despite advances in treatment, morbidity, mortality and

> costs

> > > related to asthma and other allergic diseases continue to rise.

> Since

> > > house dust mites are a major cause of these conditions, there is

> a need

> > > in the art for a safe and effective way of killing mites in

> clothing and

> > > other fabrics.

> > > SUMMARY OF THE INVENTION

> > > [0006] The present inventor has found, surprisingly, that

> exposing

> > > woolen or other fabrics to the vapors of certain pleasant-

> smelling plant

> > > oils, including wintergreen oil, lavandin oil, Ylang-Ylang oil,

> and

> > > others, kills house dust mites in those fabrics.

> > >

> > > [0007] In one aspect of the present invention, a method for

> killing

> > > house dust mites which are living in or infesting a fabric

> substrate is

> > > disclosed. The method includes the step of exposing said mite-

> infested

> > > substrate to a vapor of at least one plant oil. The plant oil

> may be

> > > selected from the group of Anise, Balsam, Basil, Bay, Birch,

> Cajeput,

> > > Camphor, Caraway, Cinnamon, Clove, Coriander, Dill, Fennell, Fir,

> > > Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> Peppermint,

> > > Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja, Thyme,

> > > Wintergreen and Ylang-Ylang.

> > >

> > > [0008] In a preferred method, the exposing step comprises

> placing the

> > > mite-infested substrate in a closed drawer or other closed

> container

> > > along with a volume of the selected plant oil. The plant oil can

> be

> > > applied to the substrate in a variety of manners as can be

> understood

> > > from the following detailed description.

> > >

> > > [0009] These and other features and aspects of the present

> invention can

> > > be better appreciated from the following description of certain

> > > preferred embodiments.

> > > DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTS

> > > [0010] I discovered that exposing woolen clothing or other soft

> fabrics

> > > infested with house dust mites to the vapors of several plant

> > > oils—including the oils of Anise, Balsam, Basil, Bay, Birch,

> > > Cajeput, Camphor, Caraway, Cinnamon, Clove, Coriander, Dill,

> Fennell,

> > > Fir, Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> > > Peppermint, Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree,

> Thuja,

> > > Thyme, Wintergreen and Ylang-Ylang—kills the mites in such

> clothing

> > > as well as their eggs.

> > >

> > > [0011] The oils used are aromatherapy-grade oils produced by

> steam

> > > distillation of the specific plant, and readily available

> commercially

> > > from many suppliers. These oils release vapors spontaneously,

> and thus

> > > can be placed in contact with the mite infested substrate in

> many ways,

> > > e.g. placing a few drops of the oil on an absorbent material

> such as a

> > > paper towel or piece of cotton, which is then placed in a closed

> > > container, such as a closed drawer or a sweater storage box,

> containing

> > > the infested fabric. Alternatively, several drops of the oil may

> > > placed in a plastic or glass dish within such a closed container.

> > > Application may also be effected by spraying a mist of the oil

> > > substrate by means of a simple atomizer, and then placing the

> treated

> > > object into a sealed container that allows the accumulation of

> the oil

> > > vapor. In the case of substrates which can not be placed within

> > > containers for treatment, such as carpets, the vapor of the oil

> may be

> > > contained long enough for it to have its desired effect by

> placing an

> > > impermeable barrier such as plastic sheeting over the carpet

> which has

> > > been sprayed with the oil, and leaving such barrier in place for

> a

> > > sufficient time to kill mites, such as, for example, 24 hours.

> > > Additional methods of dispersing the vapor of the oils include

> > > effective.

> > >

> > > [0012] The substrates encompassed by the methods of the present

November 29, 2008

I found cedarcide a great tool as a rappelent, not a killer. I use it

on my body and head all the time. I especially like to spray my socks

and clothes with it. i've never spayed the house though. It's to

slippery on the HW flooring or me. I do think it would help suffocate

direct hits though. Trish's ESP essential oil mix which I've added

clove and eucyptus oil to, seems to be a killer in my car and house,

although not right away. And dust mites are easier to kill.

> > A1

> > Abstract: The present inventor has found, surprisingly, that

> > exposing woolen or other fabrics to the vapors of certain

> > pleasant-smelling plant oils, including wintergreen oil, lavandin

> oil,

> > Ylang-Ylang oil, and others, kills house dust mites in those

> dust

> > mites which are living in or infesting a fabric substrate is

> disclosed.

> > The method includes the step of exposing said mite-infested

> substrate to

> > a vapor of at least one plant oil. The plant oil is selected from

> the

> > group of Anise, Balsam, Basil, Bay, Birch, Cajeput, Camphor,

> Caraway,

> > Cinnamon, Clove, Coriander, Dill, Fennell, Fir, Garlic, Lavender,

> > Description: FIELD OF THE INVENTION

> > [0001] This invention pertains to a method for killing house dust

> mites

> > in soft materials such as clothing.

> > BACKGROUND OF THE INVENTION

> > [0002] It has been known for many years that common house dust is

> an

> > important cause of asthma, rhinitis and eczema in allergic

> individuals.

> > The mite Dermatophagoides pteronyssinus and related mites are

> the

> > major sources of house dust allergen in temperate climates

> including the

> > United States. Dust mites are eight-legged arachnids, relatives of

> > spiders. They live in close association with humans, their main

> food

> > source being the shed scales from skin. A major protein allergen

> present

> > in the fecal particles of Dermatophagoides pteronyssinus, Der

p

> I,

> > can cause acute asthma symptoms when present at levels greater

than

> > 10Î¼g per gram of dust.

> >

> > [0003] Dust mites are photophobic, and live within soft materials

> such

> > as pillows, mattresses, blankets and clothing. One study revealed

> 20,000

> > live dust mites in a jacket. Another study showed mean Der p I

> levels

> > of 15.9 Î¼g/gm in all clothing and 21.0 Î¼g/gm in woolen garments.

> > Hot water washing, dry cleaning, freezing and prolonged sun

> exposure can

> > kill mites in fabrics. These methods are not practical for all

> fabrics,

> > or may not be practical to do frequently.

> >

> > [0004] Since mites are not insects and are not even closely

> related to

> > insects, it is not surprising that many insecticides do not kill

> mites.

> > Chemical miticides exist which can kill some types of mites, but

> most of

> > these have been developed for agricultural use, to kill plant-

> eating

> > mites which infest growing crops or stored grain, and which

> constitute

> > different mite species. Use of a chemical substance indoors, and

> > particularly on clothing or carpeting in close contact with the

> user,

> > obviously requires that the chemical be safe and pleasant.

> >

> > [0005] Despite advances in treatment, morbidity, mortality and

> costs

> > related to asthma and other allergic diseases continue to rise.

> Since

> > house dust mites are a major cause of these conditions, there is

a

> need

> > in the art for a safe and effective way of killing mites in

> clothing and

> > other fabrics.

> > SUMMARY OF THE INVENTION

> > [0006] The present inventor has found, surprisingly, that exposing

> > woolen or other fabrics to the vapors of certain pleasant-

smelling

> plant

> > oils, including wintergreen oil, lavandin oil, Ylang-Ylang oil,

and

> > others, kills house dust mites in those fabrics.

> >

> > [0007] In one aspect of the present invention, a method for

killing

> > house dust mites which are living in or infesting a fabric

> substrate is

> > disclosed. The method includes the step of exposing said mite-

> infested

> > substrate to a vapor of at least one plant oil. The plant oil may

> be

> > selected from the group of Anise, Balsam, Basil, Bay, Birch,

> Cajeput,

> > Camphor, Caraway, Cinnamon, Clove, Coriander, Dill, Fennell, Fir,

> > Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> Peppermint,

> > Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja, Thyme,

> > Wintergreen and Ylang-Ylang.

> >

> > [0008] In a preferred method, the exposing step comprises placing

> the

> > mite-infested substrate in a closed drawer or other closed

> container

> > along with a volume of the selected plant oil. The plant oil can

be

> > applied to the substrate in a variety of manners as can be

> understood

> > from the following detailed description.

> >

> > [0009] These and other features and aspects of the present

> invention can

> > be better appreciated from the following description of certain

> > preferred embodiments.

> > DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTS

> > [0010] I discovered that exposing woolen clothing or other soft

> fabrics

> > infested with house dust mites to the vapors of several plant

> > oils—including the oils of Anise, Balsam, Basil, Bay, Birch,

> > Cajeput, Camphor, Caraway, Cinnamon, Clove, Coriander, Dill,

> Fennell,

> > Fir, Garlic, Lavender, Lavendin, Lemongrass, Marjoram, Nutmeg,

> > Peppermint, Pine, Rosemary, Rue, Sage, Spearmint, Tea Tree, Thuja,

> > Thyme, Wintergreen and Ylang-Ylang—kills the mites in such

clothing

> > as well as their eggs.

> >

> > [0011] The oils used are aromatherapy-grade oils produced by steam

> > distillation of the specific plant, and readily available

> commercially

> > from many suppliers. These oils release vapors spontaneously, and

> thus

> > can be placed in contact with the mite infested substrate in many

> ways,

> > e.g. placing a few drops of the oil on an absorbent material such

> as a

> > paper towel or piece of cotton, which is then placed in a closed

> > container, such as a closed drawer or a sweater storage box,

> containing

> > the infested fabric. Alternatively, several drops of the oil may

be

> > placed in a plastic or glass dish within such a closed container.

> > Application may also be effected by spraying a mist of the oil

> onto the

> > substrate by means of a simple atomizer, and then placing the

> treated

> > object into a sealed container that allows the accumulation of

the

> oil

> > vapor. In the case of substrates which can not be placed within

> closed

> > containers for treatment, such as carpets, the vapor of the oil

> may be

> > contained long enough for it to have its desired effect by

placing

> an

> > impermeable barrier such as plastic sheeting over the carpet

which

> has

> > been sprayed with the oil, and leaving such barrier in place for a

> > sufficient time to kill mites, such as, for example, 24 hours.

> > Additional methods of dispersing the vapor of the oils include

the

> use

> > of a packet containing a solution or gel of the plant oil having

> on at

> > least one surface of the packet a permeable membrane through

which

> the

> > vapor volatilizes either spontaneously or with the help of

electric

> > heat, as in an air freshener. All of these methods have proven to

> be

> > effective.

> >

> > [0012] The substrates encompassed by the methods of the present

> > invention include without limitation clothing, carpeting, bedding

> > materials, upholstery, toys made from fabrics, and other soft

> fabrics.

> >

> > [0013] The present invention is further described in the following

> > working examples, which are intended to illustrate the invention

> without

> > limiting its scope.

> > EXAMPLE 1

> > [0014] The ability of various plant oils to kill house dust mites
