Fly spray

Fly spray is a chemical insecticide that comes in an aerosol can that is sprayed into the air to kill flies. Fly sprays will kill various flying insects such as house flies and wasps. Fly sprays often contain the powerful insect toxin dichlorvos which is often targeted by environmental groups as a carcinogenic compound. Fly sprays kill insects by interrupting the nerve signals from the motor neurons in the insect. This in turn causes them to go into a permanent contraction which makes flying and respiration impossible, and the insects then die of asphyxiation. Fly spray contains chemicals that bind to and permanently block the action of an enzyme called acetylcholinesterase. Acetyl choline is the nerve transmitter substance released by motor neurones to stimulate muscle contraction. The muscles relax when the ACh is removed from the neuromuscular junction by the action of acetylcholinesterase. By inhibiting the cholinesterase the fly can no longer break down ACh in the NMJ and so its muscles lock up in a state of tetany making flying and respiration impossible.
