From the first warm days in March, ants begin crossing Wilmington driveways, stoop steps and kitchen counters. The city's brick and concrete provide the cracks and crevices pavement ants like, mature trees offer nesting wood for carpenter ants, and humid summers keep everything active. Most ants are harmless, but a few quietly cause real damage.

Common ants in the Mid-Atlantic
- Pavement ants nest under slabs, patios and sidewalks and push up little hills of sand in cracks. They enter homes in search of grease and sweets.
- Odorous house ants form big, multi-queen colonies in wall voids and under floors. Crushed, they smell like rotten coconut.
- Carpenter ants prefer damp or rotted wood and are black and large. They are found in tree stumps, fences, porches and wet framing.
- Citronella and field ants are less common; citronella ants nest in soil and are often seen when they swarm in late summer.
Argentine ants and fire ants are generally southern problems and are not typical here.
Wilmington housing quirks
Brick rowhouses with small rear yards, concrete patios and basement windows set at ground level create ideal pavement ant access. In neighborhoods with big old trees, such as Highlands and Forty Acres, limbs reaching the roof give carpenter ants a bridge into attics. Older houses with flat-roof sections or failing flashing can develop wet wood that a colony quickly claims. Basement bathrooms and kitchens add another source of moisture.
What treatment looks like
- The technician identifies the species and the trail they follow, because treatments differ.
- For sweet-feeding ants, bait placements let workers carry active ingredient to the nest.
- For carpenter ants, the focus is finding the nest, treating it directly and correcting wet wood.
- Exterior perimeter applications create a barrier along foundations, door frames and utility entries.
- Repeat visits confirm trails have stopped.
Prevention list
- Keep branches trimmed back at least a few feet from the roof.
- Seal cracks in foundations and around windows and pipes.
- Wipe up sticky spills at once and wash pet bowls.
- Store firewood off the ground and away from the house.
- Repair gutters, flashing and leaky faucets.
- Take out garbage daily during summer.
Timing and seasons
Pavement ant swarms may appear on warm days in late spring and early summer, which can look alarming but is usually a short event. Carpenter ant swarmers inside the house point to a nest nearby. Autumn rain often pushes colonies indoors, while winter sightings call for a closer look at hidden moisture.

Frequently asked questions
Why do ants appear suddenly in the kitchen?
A scout found a food source and laid a scent trail. Cleaning thoroughly and removing the trail can slow them while baits work.
Are swarming ants a sign of termites?
Not always. Look at the waist and wings: termites have a thick waist and straight antennae, ants a narrow waist and bent antennae.
Can I use store-bought ant bait?
It can help with simple sugar ants, but carpenter ants or large colonies often require professional methods.
Will ants damage my row home?
Pavement ants will not, but carpenter ants can weaken wood that is already wet, so check moisture problems.
