NALED Insecticide Fact Sheet
Naled is an insecticide in the organophosphate pesticide family that is commonly used to kill adult (flying) mosquitoes.
Naled has been registered for use in the U.S. since 1959 and is sold under the brand name Dibrom. AMVAC Chemical Corporation has been the major manufacturer of NALED since 1998.
Naled is a fast acting, non-systemic contact and stomach poison in insects and mites (2). It is used as a short-term fumigant to control agricultural pests on ornamentals in greenhouses, animal and poultry houses, kennels and food processing plants (1, 6). Liquid formulations can be applied to greenhouse heating pipes to kill insects by vapor action. Naled is also used for municipal and other large area mosquito control programs (3). It has been used by veterinarians to kill parasitic worms (other than tapeworms) in dogs (6). Naled is available in dust, emulsion concentrate, liquid and ULV formulations (3).
Naled is one of a class of insecticides referred to as organophosphates. These chemicals act by interfering with the activities of cholinesterase, an enzyme that is essential for the proper working of the nervous systems of both humans and insects. Please refer to the Toxicology Information Brief on cholinesterase-inhibition for a more detailed description of this topic.
