Citrus extract

Description

Several insecticidal substances are extracted from fresh peels of citrus fruits. The most important of these is d-limonene; another is linalool. D-limonene, which is a volatile oil, constitutes approximately 98% of orange peel oil by weight and has moderately good knockdown activity against ectoparasites of companion animals. The insecticidal activity of both d-limonene and linalool is enhanced when synergized by piperonyl butoxide. Apart from toxicoses reported in cats (65), d-limonene generally has a high margin of safety.
