Guy you've got it all wrong! These invertebrates don't have the complex central nervous system as higher animals! Their is no neurotransmitter or nervous system potentiating the propagation of action potentials in this organism.
Furthermore! AntiAcetylcholinesterases don't selectively pick out certain neural synapses to block! It's always all or nothing. A block will result in any of the following: fasciculations, floppyiness and paralysis not spasms or tremors.

Chaiii!!!

I think its just simple physics based on equilibrium whatever.. Lol first we all know a roach spreads its limbs apart from each other and walks that way.. On dying, I think just like animals do stretch in a dying process, the roach kind of clench to its fore limbs together as a pair and likewise the hind limbs, then this cause the roach to seem like a prism or triangle placed to balance on its edge, and we know objects can only balance on its sides and not on its tip, so in the process the roach tumbles and lands on its back which appears to be a side of it and a good balance position to the ground. And that's how it ends up on its back.

In ENGLISH please!

they die gasping for breath, because the insecticides attacks their spiracles which is the only medium
for breathing. guess where its located? their abdomen...

Did you study insectisery or your final year thesis is on study of cockroaches?. You seem to know much.

Actually I think it's a copy and paste.

Several things can hinder an insect's ability to resituate itself. Ingesting pesticides and insecticides such as bug spray disrupts the bug's neurotransmitters and shuts down its nervous system. As a side effect, most pesticides cause an insect to go into convulsions, during which it uncontrollably kicks up its legs and often gets stuck on its back. With its nervous system compromised and its coordination declining, the bug lacks the ability to synchronize all of its legs in order to roll over onto its side and stand back up. Depending on the pesticide, a bug can die within hours or days of ingesting the poison.
