Pests we treat around New Castle
Pests in New Castle
What we deal with most around New Castle, DE
Buildings that have stood a long time tend to have more small gaps, and that is where mice and other rodents, spiders and cockroaches get their start. Termites and carpenter ants are a particular worry wherever old wood meets damp ground. Along the water and in parks, mosquitoes and ticks are common in summer, and wasps often nest under roof edges and porch ceilings.
Winters here are a little harder than in much of the state, with about 92 nights at or below freezing and roughly 20 inches of snow in a typical year. That drives rodents and overwintering insects indoors. Summer brings about 22 days at 90 degrees or higher, when ants, flies and mosquitoes are at their most active.
Weather and pests
How New Castle's weather affects pest activity
New Castle's July highs average about 87 degrees, and January lows average around 26. In a year the area typically gets about 45 inches of precipitation, and June is generally the wettest month at nearly 5 inches. These are 1991-2020 NOAA climate normals from a nearby weather station, so they are a guide and not a forecast.
A soggy June is right when mosquito populations are building, and water collects in gutters, low ground and anything that can hold a puddle. Wet soil near a foundation also keeps termites and carpenter ants comfortable. Snow and hard freezes later in the year send mice toward attics and basements, so the time to seal gaps is before the cold arrives, not after you hear scratching.
We usually suggest a simple yearly plan: inspect the exterior and treat as spring begins, keep an eye on standing water in early summer, close up gaps in early fall, and look at attics and basements during winter. We can fit that plan to your property whenever you want to discuss it.
How we fix it
Pest control services in New Castle
Ant treatment in New Castle
Ants are among the most common calls we get in New Castle, from sugar ants in kitchens to carpenter ants in damp or damaged wood. Activity climbs quickly once spring temperatures arrive. We find the trails and the nest, treat where the colony lives and follow up so they do not simply return.
Rodent control in New Castle
Mice and rats look for food, warmth and shelter, and New Castle buildings offer plenty of all three. With a long cold season, the pressure builds every fall. Our exclusion-based approach combines inspection, sealing entry points, trapping and monitoring, so you fix the reason rodents got in, not only the rodents you can see.
Termite control in New Castle
Termites are a quiet threat because damage often goes unnoticed for years. Regular moisture around foundations makes regular checks especially worthwhile. We inspect for mud tubes, damaged wood and moisture problems, then treat with a plan matched to how your New Castle home is built.
Cockroach control in New Castle
Cockroaches are hard to get rid of with store-bought sprays. We locate the hiding places, treat cracks, crevices and voids, and use monitoring so we know the treatment worked. It is a common request in New Castle apartments, restaurants and older homes alike.
Spider control in New Castle
Most spiders are harmless, but nobody wants webs around the door or a spider in the basement. We remove webs and egg sacs, treat the perimeter and reduce the insects that spiders feed on, which keeps them from coming back.
Mosquito control in New Castle
New Castle's wet weather makes mosquitoes a real nuisance. We treat resting areas in your yard, help you find and remove breeding sites and schedule visits through the warm season so you can use your yard again.
