Without the formation of ATP, insects simply run out of gas. The Killing Power of Hydramethylnon Hydramethylnon is most active against energetic insects, and its speed of kill increases with an increase in temperature and insect activity. Insects have shown no signs of resistance to hydramethylnon. Years of research demonstrate that hydramethylnon is one of the most effective active ingredients for roach and ant baits. It is effective in the control of roaches and ants because both insects serve as carriers of the active ingredient to harborages and colonies.
Cockroaches are coprophagous, which means they eat their own feces and the feces of other roaches.
They are also cannibalistic, which means they feed on each other. After consuming a lethal dose of bait, cockroaches return to the harborage where they excrete feces containing hydramethylnon. As other cockroaches consume the contaminated feces, they too receive a lethal dose. When the roaches die, other roaches may consume their carcass and die as well. Tests have documented that this can result in one cockroach causing the death of up to 44 other cockroaches.
