Late Season Bees

Late season bee nests in homes and other structures pose numerous problems involving primarily patience. Late season populations are at their max, they are large. This includes larvae and pupae. Normally when larvae pupate they pupate into an active colony where the new bees are quickly assimilated in colony life. However if the nest has been treated the larvae pupate into a devastated colony with no guidance for the new bees. When treatment is done late in the season there are large numbers of larvae pupating daily with no sense of purpose, they are confused, and this results in odd behavior like finding ever increasing numbers inside. The pesticides do not penetrate the eggs or the pupae cases. The eggs and pupae have to hatch to become exposed to any treatment residual which will typically take about three days to terminally effect the bees. It is during this time an otherwise successful treatment appears to be failing. It may take up to three weeks for all the pupae to become exposed and die. This takes patience because it can not be sped up.
