Re: Wax Moth Control?
Starting from the bottom up, I would say it is not safe to assume that the moths are gone once the first frost hits. They need more exposure to the cold for them to be gone. I had a tough year this past fall and winter because it didn't get cold enough in my barn to kill them off and I lost some comb. Colder is better and the longer it's cold, them better. I use BT Aizawai and I can vouch for that. Not sure about the other and yes, I'd spray them on the infected frames and any unaffected brood comb that you have. That will slow and eventually stop the larvae. I typically spray my comb before storage. Last year, I brought in a couple of boxes from a dead out and didn't spray which is how my infestation started. You may consider spraying before storing in the basement. Outside, I'd let a strong hive take care of the moths. I've never had a moth problem in a strong hive. Once it gets weak, I'll combine the colony, bring the boxes and frames inside, spray and store. I'm not sure that it's necessary to worry about the ventilation so much. I use screened bottom boards so the moths can enter in a variety of locations.
