A fly spray is a chemical insecticide in an aerosol can. You spray it into the air to terminate unwanted flies. Fly sprays generally kill house flies and wasps, but some also kill insects like ants, spiders and cockroaches.

An insect or a fly that has been sprayed with it usually appear to go crazy. It accelerates its movement and ends up drowsy on its back with its legs up in the air before it dies. It happens because fly sprays have toxins that are disastrous to the nerve tissue.

If you follow the instructions mentioned in the label of a fly spray, expect your problem with flies to be over in a matter of seconds. Some of the gestures you might witness in those few seconds are probably post-mortem muscle twitches. Bigger and stronger flies might wrestle a little longer than the smaller ones.

How do fly sprays kill flies?

Fly sprays have pyrethrin as an ingredient. It is a chemical that is toxic to insects. Insecticides weakens the acetylcholinesterase enzyme that a fly must have to relax its muscles. Once applied with the fly spray, its muscles contract non-stop and makes it impossible for the fly to breathe. It suffocates right away and dies.

What is the active ingredient in a fly spray?

Different fly sprays have different active ingredients. Most of those that are being sold in the market have these – pyrethrin and permethrin.

Pyrethrins are contact poisons that functions fast in penetrating the skin or shell of the insect. When this happens, the nervous system becomes paralyzed. It is important to know that pyrethrins don’t kill the insect. There is a part of an insect the detoxifies the pyrethrins, letting some of them recover after a while, thus numerous fly spray manufacturers add synergists to their product formulas to aid in delaying the fly’s enzyme action, making sure of a lethal dose.

Permethrin works as a neurotoxin like pyrethrin. This is highly toxic to animals such as cats and will kill them. Fly sprays for horses usually have this as an ingredient. Permethrin is stronger and more stable than pyrethrin and formulas that have permethrin usually provide longer protection.
