What should you do if there is a mouse in the house? - briefly
Seal all possible entryways, store food in airtight containers, and use snap or live traps to capture the rodent; then dispose of it safely and monitor for further activity.
What should you do if there is a mouse in the house? - in detail
If a mouse is found inside the residence, immediate action reduces damage and health risks.
First, confirm the presence. Look for droppings, gnaw marks, or nesting material in concealed areas such as behind appliances, under sinks, and in wall voids.
Next, eliminate food sources. Store all perishables in airtight containers, clean crumbs from countertops, and empty pet feeders after each use. Dispose of garbage in sealed bags and remove it from the indoor environment promptly.
Identify and block entry points. Inspect the exterior for gaps around pipes, vents, doors, and windows. Seal openings larger than a quarter inch with steel wool, caulk, or metal flashing, because rodents can squeeze through very small spaces.
Set up control devices. Use a combination of the following, placing each where activity has been observed:
- Snap traps loaded with a small piece of peanut butter or cheese; position perpendicular to walls, with the trigger end facing the wall.
- Live‑catch traps if relocation is preferred; check them at least twice daily to prevent suffering.
- Glue boards as a supplemental measure; handle with caution due to their hazardous nature.
Bait placement should avoid contact with children and pets. Follow manufacturer instructions for safe disposal of captured rodents.
Maintain a clean environment to deter re‑infestation. Vacuum regularly, especially in corners and behind furniture, and repair any water leaks that could provide a moisture source.
If activity persists after several weeks of diligent trapping and sealing, contact a licensed pest‑management professional. They can assess hidden infestations, apply rodenticides where legally permitted, and provide a long‑term prevention plan.
Finally, monitor the situation for at least a month. Re‑inspect entry points and trap locations weekly to ensure the problem remains resolved.
