Mice in autumn: prevent an invasion before winter

As temperatures drop, mice leave the outdoors to find warmth and food inside homes. Autumn is the season of intrusions: it's better to act preventively than to wait for the first damage.

How mice get in

A mouse can slip through an opening of just 6 millimetres. The most common entry points are:

• poorly fitted door bottoms and thresholds;
• cable and pipe passages;
• unprotected air vents;
• cracks in façades and lofts.

The tell-tale signs

Look for black droppings a few millimetres long, night-time scratching noises in the walls, gnawed packaging and a distinctive urine smell. A single visible mouse often hides a small colony.

Mice breed all year round: an untreated autumn intrusion can turn into an infestation before spring.

Protect your home before winter

The best defence is prevention:

1. Block access with steel wool and suitable seals.
2. Store food in airtight containers.
3. Don't leave pet food out overnight.
4. Keep an eye on cellars, garages and lofts.

If mice are already established, a professional treatment eradicates the colony and secures the entry points. Contact us for a free diagnosis. As a supplement, traps and repellents help contain intrusions.
