How can I get rid of a mouse under the windowsill? - in detail
A rodent concealed beneath a windowsill can be removed by combining immediate capture methods with long‑term exclusion measures.
First, identify activity signs—droppings, gnaw marks, or fresh footprints. Use a flashlight to locate the exact hiding spot.
Next, choose an appropriate capture tool:
- Snap traps placed directly under the ledge, baited with peanut butter or small pieces of cheese.
- Live‑catch traps positioned similarly, allowing release far from the property.
- Glue boards as a last resort, placed where the mouse frequently travels.
Set traps in the late afternoon; rodents are most active at dusk. Check them every few hours, dispose of any catch according to local regulations, and reset the device if necessary.
After a capture, seal entry points to prevent re‑infestation:
- Inspect the sill, surrounding frame, and adjacent wall for gaps larger than ¼ inch.
- Apply steel wool or copper mesh to fill openings, then cover with caulk or expanding foam.
- Install weather‑stripping along the interior edge of the sill to block future access.
Maintain a clean environment:
- Store food in sealed containers.
- Remove crumbs and spills promptly.
- Keep trash bins covered and emptied regularly.
- Vacuum around the sill weekly to eliminate scent trails.
If the problem persists despite these actions, consult a professional pest‑control service for advanced exclusion techniques and thorough inspection.
