Pest Control in Derby, Connecticut

Derby sits right across the Housatonic from downtown Shelton, where the Naugatuck River comes in. It's small and steep. Streets climb from Main Street and the rivers up toward Osbornedale State Park on the west side of town, and the houses sit close together on narrow lots, often built right into the slope with retaining walls, terraced yards and basements partly below grade on the uphill side.

Much of the housing dates from Derby's mill years: wood-frame two- and three-families, older singles on stone or brick foundations, and brick blocks downtown. Older houses next to two rivers bring the same few problems year after year. Mice in the shared basements, rats along the riverbanks and the Greenway, and carpenter ants in the damp porches.

Two families, one basement, and the mice that share it

Mice are the biggest Derby call by a wide margin, especially in two-families where one unit's problem is everyone's problem within a week. Shared basements, open pipe runs and worn foundations let them travel between floors. A mouse and rat exterminator who seals shared basements is the usual fix, and it works best when the whole building is done at once.

Neighbors matter here too. Stacked houses on narrow lots share fences, sheds and trash areas, and pests don't pay attention to property lines. If one house treats and the next doesn't, it tends to come back. Our guide to mouse-proofing an older home is a good place to start.

Wet porches on the uphill side

On a sloped lot, water runs toward the foundation and pools against the uphill wall. Damp basements and wet porch framing follow, and both draw carpenter ants. Carpenter ant treatment for wet porch framing comes up regularly on these streets, and the tech can usually point out where the water is collecting. Termite swarms show up some springs in the older wood-frame houses as well, and an inspection of the porch posts and sills is worth it if you see winged insects in the basement.

Up near Osbornedale and the Kellogg Environmental Center, woods and fields run right up to the backyards, and those homes see more ticks and yellow jackets than the blocks near Main Street. Businesses along Main Street mostly call about rodents, since trash areas, loading doors and old basements give rats and mice easy cover, and a company that does commercial work can keep outdoor stations and indoor traps on a regular schedule. Derby shares its northern border with Ansonia, where the old two-families look a lot like these.
