How do you get rid of mice permanently?
Remove the mice inside with secure bait stations or traps placed along their runways, then find and seal every entry point, including gaps around pipes, vents, garage doors and weep holes. Baiting without proofing usually means new mice arrive once the bait runs out.
Signs you have mice
- Scratching or scurrying in ceilings and walls at night
- Small, rice-sized droppings in drawers, pantries and under sinks
- Chewed food packaging, paper or insulation
- A strong ammonia smell in enclosed areas
- Greasy marks along skirting and walls where mice run
Why mice are more than a nuisance
Mice contaminate food and surfaces with urine and droppings and can spread bacteria such as Salmonella. They gnaw constantly, which damages stored goods, insulation and electrical wiring. A pair of mice can produce many litters a year, so a small problem grows fast if it is left until spring.
How Pestor treats mice
Inspect
We trace droppings and runways to find nests, food sources and how the mice are getting in.
Remove
Lockable, tamper-resistant bait stations or traps are placed where mice travel, away from children and pets.
Proof
Entry points are identified and sealed or flagged for repair: pipe gaps, vents, doors and roof lines.
Monitor
Stations are checked and topped up until activity stops, with notes on what we found each visit.
Before your mouse treatment
- Move food into sealed glass or hard plastic containers
- Clear access to under sinks, the pantry floor and behind the fridge
- Note where you hear or see activity so we can start there
- Tell us about pets so stations are placed safely
Prevention tips
- Seal gaps around pipes and cables with steel wool and sealant
- Fit brush strips to the bottom of garage and external doors
- Store pet food and birdseed in sealed containers
- Keep firewood, boxes and garden clutter away from the house
- Clean up crumbs and spills, especially in pantries

FAQs about mice
How do mice get into my house?
Through any gap of about 6 mm or more: around pipes and cables, under doors, through vents and weep holes, and where the roof meets the walls. Garages are a common entry point.
Is mouse bait safe around pets?
We use lockable, tamper-resistant bait stations that children and pets cannot open, and place them out of reach. Tell us about your pets and we will plan placement around them.
How long until the mice are gone?
Activity usually drops within one to two weeks. Proofing the entry points is what keeps them gone.
Will mice die in my walls?
It can happen with baiting. Using traps in key areas and proofing entry points reduces this. If there is an odour we can help locate and remove the source where it is accessible.
