Cyromazine is a triazine insect growth regulator used as an insecticide and an acaricide. It is a cyclopropyl derivative of melamine. Cyromazine works by affecting the nervous system of the immature larval stages of certain insects.[2]

In veterinary medicine, cyromazine is used as an ectoparasiticide.[citation needed]
