How does flyspray work?


Well, with fly spray, which is the stuff you spray on nuisance flies - usually there's a short lag and then, suddenly, the fly appears to go nuts: it speeds up its activity and then all of its movements appear to become very chaotic. Then, usually, it ends up laying on its back with its legs writhing in the air, buzzing furiously before it just expires.

What's actually happening is that the fly spray is a neurotoxin. It's got chemicals in it that inhibit an enzyme in the body of the fly called an acetylcholinesterase.

This enzyme is very important for interrupting the flow of information between motor nerves and muscles. The nerves squirt out a nerve transmitter chemical called acetylcholine. This binds to special docking stations called receptors, which are on the muscle and activate the muscle. You terminate the signal by breaking down the acetylcholine with this acetylcholinesterase enzyme.

If you inhibit the enzyme with drugs or the chemicals that are in the fly spray, what happens is that you end up stimulating the muscles too much, you don't interrupt the signal and, as a result, the fly's muscles all go into tetany - they're contracting all the time and as a result, the fly becomes nonviable and also can't move its abdomen backwards and forwards to move air in and out of its body, so it can't oxygenate its haemocele, the bag of blood inside the fly; so it basically asphyxiates as well.

So that's how fly spray works! Probably not a nice death...


I can take 3 cans of this spray the humans use easily and all i recieve from it is the urge to mate immediately. Humans are very weak creatures and have to hide behind cans of spray hahahaha. The human whom lives in my fly nest cannot work out why im still alive. I like to bite her ankles at night when she hibernates. Foolish human with her spray doesnt realise that each time she sprays at me i then rape all of my 18 mates. You do the math. We rule the world, humans just live here.

Horrible way to die
Personally add a lighter to your fly spray for instant death :D
(yes I'm trolling)
