TOD is designed to have a residual effect so it is expected that all insects may succumb for months afterwards. The risk with any insect eating herp in this enclosure is twofold. TOD is not toxic via skin absorption BUT species that can lick themselves (geckoes, skinks , pygopods etc.) will therefore directly ingest any TOD. in addition, if they feed on an intoxicated insects it may not be a toxic dose to them immediately but it will accumulate after many insects have been eaten. As the TOD wears off in the environment, the insects live longer and we are more likely to consider the cage safe. BASIC RULE OF THUMB = NO TOD FOR SPECIES THAT CAN LICK, NO TOD IN ENCLOSURES WITH INSECTIVORES WITHOUT WASHING ENCLOSURE THOROUGHLY BEFORE RE USE
