It might, but don't count on it. Baits are good at grabbing termites' attention and can be used to slowly poison their colony BUT baits are not barriers and it is possible for termites to ignore them and eat your home anyway. The termites mightn't find them, the baits might be poorly placed, they mightn't suit your termites, they might be too often disturbed or left too long, too wet or too dry. Baits are great at cutting populations and even killing colonies, but it is probably best that you add other ways to keep termites out of your home, just to be sure. Of course if the service company is offering you a contract with a strong warranty, maybe you can take the risk.
