Re: Best site Info on Roach Prufe

[Guest guest]

Here is a good site that tells a little more about the Roach Prufe: http://www.copperbrite.com/newsFDA.html Rita

U.S. Food and Drug AdministrationECOLOGY AND MANAGEMENT OF FOOD-INDUSTRY PESTS“ROACH PRUFE®...the only insecticide that had shown 100% control.”

After over 10 years in preparation, under the direction of the Food and Drug Administration, Ecology and Management of Food-Industry Pests has just been released. A large segment of this 600-page hardbound reference manual sites 212 university and other scientific studies, dealing with the worst pest of all--the cockroach.Comparative Tests . . .

"In field experiments comparing (a) straight boric acid powder screened to eliminate lumps, ( proprietary boric acid formulations, and © a wide array of organic insecticides that include those most commonly used by PCOs (Pest Control Operators), one of the boric acid powder formulations (Roach Prufe®) gave long-term results superior to those from other boric acid formulations, straight boric acid, and the organic insecticides. It's superiority was evident one week after treatment, and in three months it was the only insecticide that had shown 100% control.Previous field tests had confirmed that additives to give the original Roach Prufe formulation a light bluish color and a bitter taste (to reduce the chance of the powder being eaten by small children) had serendipitously increased its effectiveness as a blatticide (roach insecticide). An increase in boric acid's inherent electrostatic charge, accompanied during the manufacturing process, probably added still more to the effectiveness of the Roach Prufe formulation."

Re: Generic Boric Acid vs Roach Prufe

I've put 20 mule team Borax (boric acid)in my carpet to stop the critters and it worked. Then I pulled out my carpet and installed Pergo (laminated flooring)and the critters were back from the floor. They weren't as bad as when I had carpet but still there. When I put borax on the Pergo it didn't help at all. I concluded that it must be the grandular shape from the borax particles getting into the moving parts of the critters that stopped them. The acid of borax is mild and may have nothing to do with stopping the critters. I was also wondering if the blue color of Roach Profe is a metal that causes the electrical charge.
