Desiccant dust and the use of CO₂ gas as a mobility stimulant for bed bugs: a potential control solution?
Journal of Pest Science 90 (1), 249-259
Abstract: The common bed bug (Cimex lectularius, Hemiptera; Cimicidae) infests homes and service industries, and the number of infestations has greatly increased over the past 20 years. At present, no cost-effective control methods are available, and eradication programs are expensive and laborious. We investigated the control potential of desiccant dust in combination with CO₂ as a bed bug activity stimulant. An initial experiment with two desiccant dusts was followed by arena studies with varying doses, available hiding places and the presence or absence of host signals. Finally, we conducted a field experiment with Syloid 244FP with or without CO₂ gas. Syloid was superior compared to diatomaceous earth, and effective at the concentration of 1.0 g/m² in the field experiment. The number of harborages and partial application of desiccant dust decreased mortality in the laboratory. Bed bug activation by CO₂ appeared of minor importance in the arena studies, but was crucial for the eradication in the student dormitories. In fact, all 5 bed bug-infested dormitories with a combined treatment of desiccant dust and CO₂ were freed of bed bugs, whereas eradication was not successful in any of the 6 dormitories with only desiccant dust treatment. The different results in the laboratory and field experiment were most likely caused by the longer activation and higher dose of CO₂ used in the field experiment than the laboratory experiment. Our study showed that application of desiccant dust in combination with release of CO₂ gas to mimic human presence is a promising option for bed bug control.
