"Dave was excellent. He was professional, honest and thorough. I thought I may have squirrels in the house because I heard scratching above a ceiling and saw a squirrel climbing my chimney with acorns in it's mouth.  
Dave inspected all the outside areas of my house and looked in my attic. He found no evidence of squirrels or bats or anything else (other than a few mice that I can take care of).
He screened off my two gable vents and recommended securing a couple of other entry prone areas which I can do.
I highly recommend Colonial Pest Control.

FAQs for termite pest control service projects in Merrimack, NH

Termite infestations display clear warning signs. Home inspections reveal mud tubes connecting wood to subterranean nests, visibly damaged or hollow wood, clusters of discarded termite wings, and areas where paint bubbles or buckles. These indicators alert homeowners to early termite activity and potential structural damage, signaling the need for a prompt professional evaluation.

Termites do not commonly bite humans or pets, but it is possible. Even if termites bite you, you aren't likely to notice or be bothered by it because their jaws are so small. If you have bug bites and aren’t sure where they are coming from, you may have another type of insect infestation. Find a local bed bug exterminator as soon as possible if you think you might have bed bugs in your home.

Many homeowners' insurance policies do not cover termite damage. Check with your insurance agent or review your policy to be sure, but it is unlikely that it is covered. However, because termite inspections are often free, you can get an annual inspection and treat problems affordably before they get out of hand.

Termites zero in on cellulose, so anything made of wood—siding, framing, or that backyard deck—can lure them in. Soft or damp lumber is an even bigger magnet, which is why leaks and high humidity spell trouble. Seal and treat exposed wood, fix plumbing leaks quickly, and keep crawl spaces dry to make your home less appealing to a wandering colony.

A termite bond is a service agreement that guarantees coverage against termite treatment costs and lasts for one to three years. These bonds secure zero additional extermination expenses during the covered period and allow for reactivation after expiration with a fee. This agreement protects homeowners from unexpected treatment costs following an infestation.
