The product features child-resistant packaging, but it should still be applied strictly in areas inaccessible to pets and children, such as deep inside wall voids or behind heavy appliances. Always store the bottle in a secure location when not in use.

Silica is added to keep the powder dry and free-flowing. This prevents the boric acid from clumping or caking, which ensures it remains easy to puff into tight spaces and effective over a longer period.

Attach the straw to the puffer bottle and insert it directly into cracks, crevices, or small openings where you suspect insect activity. A light, thin dusting is much more effective than a thick pile, as insects are more likely to walk through a fine layer of powder.
