Pest control in New Hampshire
What are the most common pests in this state, and who handles them?
Pest control in New Hampshire is led by blacklegged ticks in wooded yards from spring through fall. Carpenter ants work lakeside cottages and older homes, and cluster flies and stink bugs overwinter in attics. PestChief checks a New Hampshire ZIP code and matches the request to one local pest control company.

Is your ZIP code in New Hampshire covered?
PestChief is free to the homeowner. Coverage is checked ZIP code by ZIP code, not state by state. Give your ZIP code and the pest you are seeing, and if an independent local pest control company covers that ZIP code and handles that pest, your request goes to that one company, and it contacts you directly.
What licensing should you ask a company for?
Licensing is the one check a homeowner can make before any work starts. Every state requires a pest control company to hold a license, and most require a separate certification for specialty work such as termite treatment. Ask for the license number, confirm it covers the pest you have, and check it with the state agency that issues it.

A few state specific details that change how pest control works here, and what they mean for a homeowner.
Which metro areas are covered?
Coverage varies inside a state, not only between states. A company that covers one metro area may not cover a rural ZIP code two counties away, and the pests it is licensed to treat can differ as well. The metro areas listed here are where PestChief most often has a company to introduce you to. If your city is not listed, a ZIP code check is still worth doing.
