Bedbugs can be carried from one dwelling to another in furniture, particularly beds, in luggage from hotels both at home and abroad and in second hand furniture. They can migrate along terraced houses and between flats, spreading the problem away from the original infestation. Outer clothing can become infested and second hand clothing may also spread infestations.
Bedbug mouthparts are well adapted for piercing the skin and sucking blood. They are not known to be carriers of diseases, but can cause a painful bite.
