Borate Powder has many important 'flea-killing' features. The 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).
Shake well before opening. Apply to dry durfaces only. Apply directly on carpets where pets usually traffic or sleep at the rate of one pound per 300 square feet. Work powder deep into fibers and mat with a broom or a rug rake. Any powder visible after application must be brushed into carpet fibers or vacuumed. Remove loose cushions of upholstered furniture. Apply powder along creases and into corners and furniture wells. Work powder deep into wells and the surrounding fabric until it disappears. Any powder visible after application must be removed by vacuuming before replacing cushions. Reapply as necessary.
