Delmar straddles the Delaware–Maryland line along the rail corridor, a mix of older and newer housing set in farm country.

Pest control in Delmar
Delmar runs along the state line and the rail corridor, with farm country on both sides and housing that spans older and newer construction.
Farm fields push ants and overwintering pests toward warm structures, and both housing types offer entry points at the foundation and around utility lines.
Common pests in Delmar, Delaware
Field edges and mixed housing account for most of what we treat here.
Ants
Ants trail in from field edges and foundation cracks looking for moisture and food.
Stink bugs
Stink bugs gather on sunny walls in fall and work into siding and attics to overwinter.
Spiders
Spiders follow other insects indoors and settle in basements, corners and garages.
Mice
Field mice press toward homes in fall through foundation and utility gaps. Mice nest in wall voids and quiet storage.
When pests show up here
Seasonality tracks the farm calendar and the temperature.
- March to May: ants become active as the ground warms.
- Spring through summer: ant trails indoors.
- Late summer: spider activity peaks.
- September to October: stink bugs cluster on walls to overwinter.
- Winter: overwintering insects emerge on warm days.
Cold weather slows ants but drives overwintering pests into walls.
Autumn rodent and wildlife pressure in Delmar
Delmar's housing sits on the state line with field edges on both sides, and the autumn rodent push arrives from whichever side is cut first. Because the town straddles the border, the harborage sustaining a problem is sometimes on the Maryland side and outside what we can treat — we will say so rather than keep trapping a structure that is being restocked.
Field ants and overwintering stink bugs get the attention here in autumn, but the quieter movement is mice coming off the field edges into the housing as the nights cool. Stink bugs are conspicuous and harmless; the mice are neither.
Sealing done for stink bugs in September — window frames, siding gaps, eaves, utility penetrations — closes most of the rodent routes at the same time, which makes it the most efficient month of the year to do it.
Getting service in Delmar
Homes on both sides of the line are inspected the same way.
An inspection covers:
- the foundation line where soil meets siding
- gaps around windows, doors and utility penetrations
- sunny walls and soffits where stink bugs gather
- basements and garages for spider harborage
From there the plan is integrated pest management: seal entry points, treat harborage, and monitor rather than spray on a schedule.

Where the problem is a burrow line rather than an indoor sighting, rat control and exclusion starts outside the Delmar property and works in.
