Dense blocks, old brick foundations, alleys and a long river frontage add up to an environment that rodents like. In Wilmington, Norway rats burrow beneath porches and slabs, and house mice find their way into kitchens through gaps no wider than a pencil. The solution is not simply setting traps; it is understanding where they live, how they enter and how to shut the door permanently.

What is in the walls
- Norway rats dominate urban Mid-Atlantic cities. They live in burrows, sewer-adjacent voids and basements, and they travel along alley walls and fences.
- House mice infest kitchens, pantries and the spaces behind appliances.
Signs you shouldn't ignore
- Dark droppings along baseboards, in cabinets or on top of basement beams.
- Grease marks along walls and pipe runs.
- Burrows with smooth, packed entrances along foundations, fences and under steps.
- Gnawed food boxes, soap bars, wiring and wood trim.
- Scratching, squeaking or running noises after dark.
Why Wilmington's building stock matters
Row homes in neighborhoods such as the Hilltop, Browntown and the Westside often back onto alleys where trash is stored, and the party walls between them can carry mice from house to house. Cracked basement floors, old coal chutes, abandoned utility lines and missing mortar are common entry points. Vacant or neglected lots nearby may harbor burrows that feed neighboring homes. Winter cold and river dampness push both species indoors from October on, while heat also moves rats around in summer.
The removal process
- Survey the interior and exterior to map runways, gnaw sites and entries.
- Control the population with traps and, where appropriate, tamper-resistant bait stations placed according to label directions.
- Exclude with hardware cloth, copper mesh, sheet metal and mortar so new rodents cannot move in.
- Clean up by removing droppings and contaminated insulation using proper protective equipment.
- Monitor over the following weeks to confirm activity has ended.
Practical tips for owners and tenants
- Keep trash in sturdy lidded containers and do not set bags out overnight.
- Rinse bottles and cans before recycling.
- Do not feed pigeons or stray animals, because spilled seed feeds rodents.
- Store food in glass or hard plastic.
- Remove clutter, wood piles and debris from yards and basements.
- Repair door sweeps and cover vents with metal screens.
Timing matters in Wilmington. Rats are most visible at dusk along alleys and fences, and a quick evening walk around your block can reveal fresh burrows. Mice, on the other hand, make themselves known after the house goes quiet. Writing down when and where you notice activity helps a technician plan trap placement and saves a visit.
Business and property considerations
Restaurants and apartment owners should consider an ongoing monitoring plan. In multi-unit buildings, working together on exclusion is far more effective than each tenant fighting alone.

Frequently asked questions
Is it a rat or a mouse?
Rat droppings are around the size of a raisin, whereas mouse droppings are closer to a grain of rice. Burrows outdoors usually point to rats.
Why do rodents keep coming back?
Because access or food was not eliminated. Sealing and sanitation are as important as trapping.
Are rodents dangerous?
They can contaminate food and surfaces, damage wiring and carry disease-causing organisms, so prompt action matters.
Should I use glue boards?
Many professionals prefer snap traps and exclusion because they are quicker and more humane. Ask your provider what they recommend.
