Question

Exterminators have observed that their hydramethylnon-corn syrup baits initially work for attracting cockroaches, but the effectiveness lessens over time. does this mean that the aversion trait evolves in the cockroach populations exposed to the bait

Answer 1

Yes, I would say that the immunity to the baits of the cockroaches increases with time so that it will no longer be effective in exterminating them so a different type of insecticide may be necessary for successful extermination in the future.
