The likelihood of an infestation of bed bugs is greatly increased in premises with poor, crowded and unhygienic conditions although it can occur in well maintained premises and the infestation can be detected and thus treated at an earlier stage. The eggs will be seen in beds, mattress seams and the backs of headboards along with dark spots of bed bug excrement.
In all cases, and particularly infestations of well-kept premises, it is important to try to locate the source of the infestation and a thorough inspection is needed to determine the extent of the infestation since this affects the control measures needed.
The main control measure is the use of insecticide – for example thorough use of a suitable aerosol sprayed onto furniture, room fabrics and other harbourages. Infested clothing and bedding must be laundered (or burnt) and close attention paid to removing fluff, dust and other debris from anywhere which can harbour the pests; for example cracks, seams and around mattress buttons.
If the infestation is traced to birds’ nests then the nests will require treating and the building often rendered bird-proof to prevent re-introduction.
