Beyond bed bugs and hornets, many insects can move into your home. Each has its habits and risks: knowing them helps you act fast.

Cockroaches: discreet but dangerous

Recognise: flat brown or black body, active at night, in kitchens and bathrooms. Why act: they contaminate food and breed very fast. Cockroach treatment.

Ants: small but invasive

Recognise: they move in columns towards sweet food. Why act: harmless to health, but some species such as carpenter ants can damage wood, a real issue in chalets. Ant and other insect treatment.

Wasps: dangerous when nesting

Recognise: yellow and black body, narrow waist, nests under roofs, in lofts or walls. Why act: painful stings, dangerous for allergic people. Nest removal.

Ant, moth and mosquito
Ants, moths and mosquitoes: lesser-known pests that are just as annoying.
