I don't have a treatment contract. Once you have a short list to consider, check with the Better Business Bureau for unresolved complaints against a company. Get three or four estimates for treating your home. Most companies don't charge for estimates. Try to get someone with at least three to five years' experience to install the bait system or apply chemicals, or if that's not possible, request the most experienced employee.
Turnover is high in the pest control industry.
It takes knowledge of termite behavior to treat properly, even to do something as seemingly simple as knowing where to place bait stations. With your home at stake, there's too much at risk to depend on someone not trained in this work. Bait systems aim to eliminate or reduce a colony enough that it is no longer a threat to your home. Chemical treatments provide immediate control but involve applying some 200 gallons of termiticides into and around your home. The chemicals lose their effectiveness starting about five years after treatment, so you'll need to retreat.
