With Inside Flea Relief , you simply sprinkle the crystals once onto carpets and then brush or sweep them deeply into the fiber and mat, where fleas reside. For upholstered areas, the crystals are similarly worked into the folds and crevices. Inside Flea Relief is odorless and virtually dust free. There is no danger to children and pets, however they should not be in the treatment area until after application is completed. The product does not harm furniture.
Borates are derivatives of the mineral boron.
The killing effect is achieved by dehydration of the insects. Inside Flea Relief is registered with the Federal Environmental Protection Agency . The product is available in 1.5 pound containers, with guaranteed and lasting flea-killing power to cover 150 square feet. One simple application, using a yard sprayer, gives three months protection. No pesticides are involved.
