Why rodents are more dangerous than they seem
Mice and rats in a house mean more than spoiled food. They gnaw wiring (a fire risk), carry infections, contaminate rooms with droppings, and breed fast. One pair of mice produces a large brood in a season, so you must react at the first signs.
How rodents get into a house
Mice squeeze through an opening about a centimetre wide; rats need a little more. Typical routes: cracks in the foundation, utility entries (pipes, cables), unmeshed ventilation openings, gaps under doors, roof damage, and open basement vents.
Sealing entry routes
This is the foundation of rodent control for a house — without it, new rodents will keep coming. Inspect the perimeter and seal openings with durable materials: expanding foam will not stop rodents; you need metal mesh, cement, and metal collars around pipes. Fit fine mesh on ventilation and vents.
Bait stations versus traps
- Plastic bait stations — safer for children and pets, protect bait from moisture, suit ongoing control around the perimeter.
- Mechanical traps — good inside living spaces where poison is undesirable, and for checking results.
In practice they are often combined: stations outside and in outbuildings, traps inside the house.
Why poison alone is not enough
Laying poison without sealing cracks gives a temporary effect: the population recovers from new arrivals. A rodent may also die in an inaccessible place — in a wall or under the floor — and a smell appears. So professional rodent control is always a package: inspection, sealing routes, bait at the right points, and monitoring.
When to call professionals
Contact a service if rodents are visible in daytime, you hear noise in walls and the attic, droppings appear in several places, or DIY measures show no result in 2-3 weeks. For a house, a service contract with regular visits is often more sensible, especially in autumn when rodents head for warmth.
Prevention
- Do not leave pet food or groceries accessible; store grains in tight containers.
- Clear clutter in the basement, attic, and yard — it shelters rodents.
- Mow grass and clear plant debris along the house walls.
- Keep compost and bins away from the house, tightly closed.
- Check the perimeter each season for new cracks and damaged mesh.
