SAFE AND EFFECTIVE FLEA POWDER FOR CARPET AND FURNITURE Fleabusters Rx for Fleas Plus Powder has many important 'Flea-Killing' features. The Unique Borate Powder is milled to be extremely fine and is also statically charged. The 'fine' powder allows for easy installation while brushing into the carpet and for light application (very small amounts need to be applied for effectiveness). The 'statically charged' powder provides a clinging effect to carpet fibers. This allows very little to be removed by vacuuming, thereby providing long-lasting protection. It attaches to the flea larvae as they wiggle by. The effectiveness of killing (dehydrating) flea larvae is greatly increased. The Rx for Fleas Plus also has a neutral pH of 7.0. While being very safe for carpets, the neutral pH is actually more important in a pest control sense by not causing the targeted pest (flea) to be repelled from the powder. Roaches, ants, fleas, etc., can sense and avoid an alkaline or acidic substance, but crawl right through the neutral pH material.
