What’s the risk for me and my belongings?

The bed bug has not been proven to transmit human disease but its bites are very irritating and painful. The irritation is caused by the bed bug saliva.

The bed bug injects an anticoagulant through its bite and an analgesic, to avoid awakening its host. It usually bites between 12 to 4 am. The bed bug exclusively feeds on blood.

Skin bites can cause severe itching. If itching is too intense, skin bite scratching can cause infection and scars.

People who have bed bugs can suffer from anxiety, stress, sleep disorder and fatigue.

In case of severe infestations, blood and fecal marks can stain furniture or other belongings permanently.
