Bed Bugs


Bedbugs have recently undergone a dramatic resurgence and worldwide there are reports of increasing numbers of infestations. Bedbugs are wingless insects, roughly oval in shape and 4–5mm long.

They move quickly and can hide in narrow cracks and crevices, making detection very difficult. They are rust brown in colour and change to a deeper red brown after feeding.

Bedbugs shelter in a variety of dark locations, close to where people sleep. These include under mattresses, floorboards, paintings and carpets, behind skirting, in various cracks and crevices of walls, within bed frames and other furniture, and behind loose wallpaper.

Bedbugs tend to stay in close contact with each other and heavy infestations are accompanied by a distinctive sweet sickly smell. Blood spotting on mattresses and nearby furnishings is often a tell tale sign of an infestation.

Economic and health impacts of bedbugs

Bites from bedbugs often cause localized skin reactions resulting from the saliva injected during feeding. Some people will suffer a great deal of discomfort often with loss of sleep from persistent biting. The most commonly affected areas of the body are the arms and shoulders. Reactions to the bites may be delayed; up to 9 days before lesions appear. Common allergic reactions include the development of large weals that are accompanied by itching and inflammation.

It has been suggested that allergens from bedbugs may be associated with asthmatic reactions. Bedbugs have been implicated in the transmission of a wide variety of infectious agents.
