Alphacypermethrin is a synthetic pyrethroid, which works as an insecticide and repellent by inhibiting neural transmission in insects. Alphacypermethrin is lipophilic and is retained in the wool grease of the sheep fleece to provide protection from blowflies for up to 8 to 10 weeks.
Alphacypermethrin has low toxicity to mammals. There have been no tests of the effects of alphacypermethrin on foetal or lamb development.
