Pest control in Connecticut follows wet wood and stone foundations. Carpenter ants move into sills where a gutter has been dumping for years or where grade sits against clapboard. Mice use the gaps in a rubble cellar wall as soon as the nights cool. Cluster flies gather in the attics of older colonials that look tight from the road. Termites are a real question in the southern and shore towns. Say what you saw, not what you fear.
Wings on a windowsill are not a diagnosis. Powderpost dust under a beam in an old barn or ell is a different insect from a pavement ant at the kitchen threshold. Rats show up where trash and alleys allow it, more in the dense cities than on a wooded lot, though a garage with feed will draw them anywhere. Squirrels in a soffit at dawn are an entry at the roof, not a pantry problem.
Spraying the trail and leaving the wet sill is how the ants return in a month. Trapping mice and ignoring the bulkhead gap does the same. A woodpile against the house, an open compost bin, and a dryer vent with no screen are invitations. Kitchens over damp crawls in shore cottages pair ants with a plumbing or grading problem. Mention that damp if you have it. The insect is the symptom.
Ticks in the yard are a brush and deer-path issue at the edge of the lot, separate from a mouse in the stove drawer. Bats in an attic need exclusion and a cap on the entry, not a fog of spray in the bedroom. Describe rub marks, gnawed trim, and the room. Pets and children change which method belongs in the house. Say so.
Give the town, the house, and when the activity started. A spring swarm and a scratch in the attic in January are different calls. Describe wings, dust, or droppings if you can. Note the hole you already see at a sill or a vent. Call the number on this page.
