I just used an insect killer spray that quickly stuns the roach and kills it eventually. However, how does the spray work to kill the roach? The spray contains 2 active ingredients ; imiprothrin and d-phenolthrin. do they suffocate the roach?

a lot of chemical sprays interfere with nerve synapses, which basically causes complete body paralysis. Some will affect their ability to absorb nutrients from their food, which causes them to die slowly, and other still will disrupt their repiratory pathways, suffocating them......
Then there are the powders like Diatomaceous earth that essentially causes thousands of microscopic leisions on the insect's body, which leads to dehydration.
Hope this helps!

most bug sprays will either poison the bug, or it will prevent it from molting. When a bug molts it is because its growing too big for it's exoskeleton. If you prevent it from molting, you end up causing the bugs anatomy to stop the shedding and keep growing, which in turn will crush all the internal organs of the bug.

It does not kill instantly. Thats a good clue right there. It may be a substance that interferes with enzymatic action inside the bug. Many pesticides work this way.
