My very first top-bar hive has seen many problems and two failures. I have seen fire ants, varroa mites, large beetles, small beetle larvae and who knows what was in those web pods at the end of some of the top bars. I am reasonably sure some of the problems were caused or made worse by me not having a screened bottom.
Any ideas on how to treat the inside and top-bars of this hive after i give it a screened bottom? I want to be sure non of the problems survive without making the hive a danger to future colony.
