Bedbugs feed on warm blood, mainly doing so at night, making a sleeping human perfect supper. As their name suggests, they are found predominantly in the bedroom area around beds, headboards, mattresses etc. but can be found in most furniture. They are known to survive for up to 12 months without food (lying dormant in empty properties). Bites from bedbugs cannot usually be felt until some hours after the event but can cause severe irritation. A notoriously difficult problem to eradicate, bedbugs require a thorough treatment to gain control. Reasons for infestation can include unwittingly bringing back infested luggage after staying in infested premises such as hotels or can commonly be introduced when untreated second-hand furniture which is infested is introduced into the dwelling.
