An object is to provide a chemical agent that, when used on carnivorous wasps such as those belonging to the Vespidae family, instantly stops them from behaving normally, to prevent injuries caused by stings and bites. As a solution, a carnivorous wasp control agent is provided, which is characterized in that it contains, as an active ingredient, at least one type of compound selected from the group that consists of (a) cyclic monoterpene-based compounds, (b) chain monoterpene-based aldehyde compounds, (c) chain sesquiterpene-based compounds, (d) benzoic acid alkyl esters, (e) lactic acid alkyl esters, (f) octanols, and (g) phenylacetic acid esters.

The invention relates to biting arthropod repellent compositions comprising nootkatone. The application also relates to a method of repelling said biting arthropods by application of the nootkatone composition to a hard or soft surface, to a method of treating an arthropod infestation and to a method of reducing the transmission of a parasite or disease pathogen spread by a biting arthropod using the nootkatone composition.
