Tear open the cockroach bait powder sachet evenly.
Sprinkle a thin, uniform layer of powder along cockroach harborage areas, hiding spots, window sills, wall cracks, kitchen corners, garden gaps and other places where cockroaches frequently appear.
Do not sweep or wash away the powder within 2–3 days after application to ensure cockroaches can transport the bait back to their harborage.
Reapply the powder if it gets wet by rain or water, or if cockroach activity still remains after several days.
For severe cockroach infestations, place multiple small piles of powder at different cockroach activity spots for better full‑population removal effect.
