Abstract/Summary

The varied carpet beetle, Anthrenus verbasci (L.), is a major pest in museums containing artifacts or specimens of animal origin, e.g., natural science collections. Integrated pest management techniques are deployed to prevent A. verbasci access and controlling the pest should they be found on valuable artifacts. Several synthetic chemicals have been used in the past in the fight against A. verbasci and other insect pest species but the use of these chemicals (such as naphthalene and dichlorvos) is now banned following health concerns. Attention is turning towards natural compounds in the search for natural, safe alternatives. As well as having active ingredients against adult A. verbasci, it is also essential that any useful products found fall within museum budgets. Here we examine the repellent properties of four ‘off-the-shelf’ essential oils: clove, lemon, lavender, and eucalyptus. All four essential oils exhibited some repellent property, but A. verbasci found lavender and eucalyptus oils the most repellent, offering the possibility that some easy to obtain and inexpensive natural products might have a role to play in museum IPM.
