The trick to putting poison bait is:"The amount is small, the points are many, and the area is wide", that is, there are more poisoning points in a house, and the amount of medicine at each point is less, and the distribution area is wider. In this way, cockroaches can crawl out of their habitat and eat poisonous bait, and the killing effect is remarkable.

In order to prevent the failure of moisture, it is advisable to put the bait particles in the cap of the bottle. Use insecticide-containing chalk to draw on cockroach activity sites.

Around the crevices, holes, and corners where cockroaches inhabit and where they often move, use a medicated pen to draw circles or"wells"words, so that cockroaches are poisoned by scribbled powder when they enter and exit or move.
