I don't see how it is toxicologically possible for it to not be statistically evident within years for insects. Taking time to fully recover sure, along with some persistence but not being statistically evident? That sounds very weird for any agent being diluted or dispersed over time - for any level of individual toxicity - let alone one decaying organic molecules.
