A biological control is disclosed for termites, including subterranean termites such as C. formosanus, comprising a mixture of a chitin synthesis inhibitor such as lufenuron with a pathogen or opportunistic pathogen. The combination greatly enhances the effectiveness above that of the individual components. For example, P. aeruginosa is commonly found in association with termites, but it is not normally harmful to termites.
