Mice appeared under the windowsill—what to do? - in detail

Rodents have been found nesting beneath the window ledge. Immediate action prevents damage and health risks.

1. Identify entry points.

   • Examine gaps around the frame, caulking, and exterior siding.
   • Look for chew marks, droppings, and gnaw‑shaped holes.

2. Seal openings.

   • Use steel wool or copper mesh to block small cracks.
   • Apply expanding foam or cement for larger gaps.
   • Install weather‑stripping on the interior side of the sill.

3. Set traps.

   • Place snap traps or electronic devices directly under the ledge, aligned with observed pathways.
   • Bait with peanut butter, cheese, or dried fruit.
   • Check traps daily, dispose of captured animals according to local regulations.

4. Reduce attractants.

   • Store food in airtight containers.
   • Keep countertops and floors free of crumbs.
   • Remove standing water sources; fix leaks promptly.

5. Clean the area.

   • Wear disposable gloves and a mask.
   • Vacuum droppings, then disinfect with a bleach solution (1 part bleach to 10 parts water).
   • Dispose of contaminated materials in sealed bags.

6. Monitor after treatment.

   • Re‑inspect the sill weekly for new activity.
   • Maintain sealed openings and hygiene practices.

7. Consider professional assistance.

   • Engage licensed pest‑control operators if infestations persist or if structural damage is suspected.

Prompt execution of these steps eliminates the current problem and deters future incursions.
