Mouse & Rat Control in Arnold & Jefferson County
A mouse fits through a gap the size of a dime. Trapping the ones inside helps, but if the gaps stay open, more come in every fall.
So we do both. We trap or bait what's inside, and we find and seal the holes where they're getting in.
Signs you have mice & rats
- Droppings in drawers, pantries or under the sink
- Scratching in walls or the ceiling at night
- Chewed food packaging, insulation or wiring
- Greasy rub marks along walls or at gaps
How we handle it
- 1 Inspect inside and out to find entry points: utility lines, garage doors, vents, foundation gaps.
- 2 Set traps and tamper-resistant bait stations where they're active.
- 3 Seal entry points with steel wool, mesh and sealant.
- 4 Check back to remove catches and confirm activity has stopped.
What you can do in the meantime
- Store pet food, birdseed and grass seed in metal or hard plastic bins
- Keep the garage door fully closed and fix worn weather stripping
- Stack firewood away from the house
