Single-sided adhesive pad used for monitoring the presence of the common bed bug (Cimex lectularius). The set includes 4 traps. The bed bug trap primarily serves as a prevention against infestation of the mattress by bed bugs. Bed bugs are mainly attracted by skin temperature and carbon dioxide exhaled by humans. If it is known that there is a bed bug infestation nearby, this adhesive trap serves as a preventive defense against their penetration into the mattress. In case of room infestation by bed bugs, professional disinfection treatment is recommended.
