Cockroaches are among the hardest pests to get rid of. Discreet and resilient, they multiply very quickly.
Why do cockroaches move in?
Cockroaches look for warmth, moisture and food. Kitchens, bathrooms and the back of appliances are their favourite places. They arrive through pipes, boxes, packaging or neighbouring flats. In the mountains, restaurant kitchens and buildings heated through the winter make ideal shelters.
How to spot an infestation
- Cockroaches seen at night (they flee light)
- Small black droppings like ground pepper
- An unpleasant smell in heavy infestations
- Egg cases (oothecae) in corners
Health risks
Cockroaches contaminate food and surfaces with bacteria and germs. They can also trigger allergies and asthma, especially in children.
Why DIY treatments fail
Shop-bought insecticides only reach the insects you can see and leave the eggs untouched, protected in their egg cases. The infestation comes back a few weeks later.
