Trapping alone is a rental agreement with the next family of mice. We remove the current population, then seal the gaps, utility penetrations and garage sweeps they used to get inside - exclusion is the part that actually ends the problem.
Signs you need rodent control
- Droppings under sinks, in pantries or along the back of cabinets
- Scratching or scurrying inside walls and ceilings after dark
- Gnaw marks on food packaging, wiring or stored goods
- Greasy rub marks along baseboards and joists
- Shredded insulation, paper or fabric used as nesting material
How we treat it
Entry point survey
We find every gap larger than a dime - dryer vents, sill gaps, garage corners, utility chases and crawlspace vents.
Trapping & removal
Placement in active runways, checked and serviced until the activity stops.
Permanent exclusion
Sealing with rodent-proof materials plus sanitation recommendations for contaminated areas.
Why this matters in Delaware
Delaware rodent calls spike sharply in October and November as temperatures drop, and farm-adjacent properties in Kent County plus older Wilmington and Newark housing see the heaviest pressure.

Rodent Control & Exclusion is available in every Delaware county.
