When you go into a hive and totally disrupt it, the bees are working so hard to repair the hive that they do not pay any attention to the beetles and moths. I learned this after rebuilding my observation hive. The beetles walk around in the like they own it. No attacks and they are able to lay there eggs in the brood. On the third day, the bees were pulling hundreds of eggs and larva and dropping them in the clean out trays. The reason it survived this is I did not return any honey to the hive. It happens every time I take the OB hive apart.
