We fix the bait wood blocks that termites like to eat and have strong attraction to termites in the Pestman termites colony elimination system (hereinafter called Pestman), and install Pestman in the buildings, trees or dams, etc. When worker termites who go out to forage reach the soil at a certain distance around Pestman, they quickly build the ant road to Pestman because of the strong attraction of luring substances released in the soil by the wood blocks in Pestman, and then enter Pestman to feed one after another. At this time, a very small amount of poisonous bait is put into Pestman to allow worker termites to feed freely, and the returning worker termites feed the poisonous bait to the king, queen, soldier termites and baby termites in the colony through feeding behavior, which leads to the death of the whole colony termites. Or spray special termite poisonous powder on the termites feeding on wood blocks with special apparatus in Pestman. After returning to the termites colony, the powder is transmitted to other termites by hugging and cleaning, which eventually leads to the whole colony termites poisoning and death.
