Pest control in New Hampshire is mice, carpenter ants, and whatever the woods send into a warm wall. Mice move in when the first hard nights hit camps and village houses alike. Carpenter ants follow wet sills, especially where a roof dumps at the foundation or a camp crawl stays damp. Cluster flies fill attics that face the sun. Squirrels and other rodents use soffits on wooded lots. Say what you heard and where.
Powderpost dust in an old barn beam is not a carpenter ant, and a pavement ant at a slab is not a termite story. This state is cold enough that a southern termite script is usually the wrong script. Describe the insect, the dust, or the droppings. Bats in a gable need the slot closed, not a spray in the bedroom. A raccoon in a chimney needs a cap.
Trapping mice while the bulkhead and the dryer vent stay open brings them back. Spraying ants while the sill stays wet does the same. Woodpiles against clapboard, bird seed, and a crawl open to the woods are the usual partners. Lakes houses with damp undersides are a classic ant call in late spring. Mention the moisture. The animal is advertising a building fault.
A barn, a shed, or a bunkhouse will reinfest the main house if it is ignored. Say every structure. Pets and children change the method. Activity that starts the week you turn the heat on is a clue. So is scratching at dawn in the eave versus droppings in the pantry. Those are different entries.
Give the town, the kind of house, and when it started. Describe wings, dust, or droppings if you can. Note the gap you already see at a sill, a vent, or a soffit, and say whether the woods come right up to the wall. Call the number on this page.
