When it comes to pests, prevention is your best ally. A few simple habits avoid a lot of trouble and costly treatments.

1. Block entry points

Check your home regularly and seal cracks, holes and gaps around pipes, doors and windows. A mouse can get through a gap of about 1 cm.

2. Remove food sources

Rodents, cockroaches and ants are attracted by food. Store food in airtight containers, clean up crumbs and empty bins regularly.

3. Control damp

Many pests love damp places. Air rooms, fix leaks and make sure bathrooms and kitchens are well ventilated.

4. Check luggage and second-hand purchases

Bed bugs travel easily. After a hotel stay or buying second-hand furniture, check your belongings before putting them away. How to spot them.

5. Look after the outside

Trim vegetation, keep firewood away from walls and check eaves and balconies in spring: that is where wasp queens found their nests.
