It is a continual process. Installing a few baits around a home and walking away will not protect the structure. Termite colonies are living systems. Once the number of termites in one colony is reduced, the neighboring termite colonies may expand their foraging borders. In addition, new colonies may develop from termite swarmers.
Termite control is continuous for as long as the structure stands.
Care must be used when installing the baits. Household chemical odors may be transferred to the bait and potentially repel termites. If the house has been treated with conventional liquid termiticides previously, the baits must be installed outside the barrier zone. Care must be used when checking the baits. If termites are crushed during this process, the crushed bodies will repel other foragers.
