Mice
PreventaPest mouse pest control for homes and businesses
House mice are small, adaptable rodents that can live close to people all year round. They look for food, water and shelter, and can enter through surprisingly small gaps around doors, pipes, vents, roof spaces and service routes.
Common signs of mice
- Small dark droppings along skirting boards, in cupboards or near food.
- Gnawing on packaging, timber, insulation or electrical cables.
- Scratching and movement in walls, ceilings or behind kitchen units.
- Greasy marks where mice repeatedly travel along edges.
- Shredded paper, fabric or insulation used as nesting material.
Seeing one mouse does not show how large the problem is. Mice tend to move along edges and hide during the day, so a careful inspection is more useful than judging the situation from occasional sightings.
Reduce food and access
Store food in sealed containers, clean crumbs and spills promptly, keep waste covered and avoid leaving pet food out overnight. Check the gaps around pipes, doors, vents and utility entries. Door seals, mesh and suitable repairs can help, but proofing must not create a hidden route for animals already inside.
Why control can be difficult
Mice can use voids that are hard to reach and may have several routes through a building. A trap or bait placed in the wrong position can miss the main activity, while food sources and access gaps continue to support the infestation. Rodenticide can also create risks for children, pets and wildlife if used incorrectly.
A professional visit should identify the species, map signs of activity, check food and access points and recommend a control plan. Follow-up checks are important because proofing and hygiene work are part of the solution.
For workplaces and food areas
Keep records of sightings, droppings, repairs and treatment. If mice are found near food storage or preparation, isolate affected areas and follow your own hygiene and food-safety procedures.
