Using boric acid powder, the No Flea Carpet Crystals provide an easy way to kill the fleas in your home. Boric acid is abrasive to their exoskeleton, causing dehydration, while also acting as a stomach poison to affect their metabolism. Simply sprinkle on the carpet and under furniture cushions to keep the fleas under control, then vacuum them up! Make sure to follow the product label and warnings - do not apply to your pets.

99% Boric Acid (H3BO3).

Carpets: Apply to dry carpet only. Vacuum all carpeted areas in your home. By shaking container from side to side, lightly sprinkle the No Flea Carpet Crystals evenly over carpeted areas, including under beds and furniture where carpet can be seen. Any powder visible after application must be brushed into carpet fibers or removed. Please wait at least 5 days and vacuum treated areas.

Upholstery: Remove loose cushions. Apply along creases and into corners and furniture wells. Do not apply product on top of cushions. Any product visible after application should be removed. Requires approximately 2-4 weeks to kill all fleas.
