A bed bug and its exuvia

bed-bug-on-an-exuvia_2-1

One of the our recent studies looked into the bed bugs' behavior to the volatiles emitted from their own shed skins (exuviae). The study also included chemical examination of the volatile chemicals evaporating from the bed bugs' exuviae. Four pheromone compounds known as aldehydes are consistently found in the exuviae. We determined that that the shed skins retain those compounds in the glands and gradually dispense them over time. The study also indicated that living bedbugs are likely to settle down in the vicinity of the shed skins by sensing these compounds.
