Just to be clear what I was saying and promoting. Sorry I did not mean to imply destroying the bottom board. I was meaning collect the dead bees and debris off the bottom board treating them as a biohazard and to not just dump and scrape those off onto the ground.
- No need to destroy any equipment or frames. Just spray treat, let dry, followed by rinse a day or two later and open air sunshine exposure to all the parts and frames.
- Yes, do collect the bees carcasses and debris and burn them. Do not toss out on the ground or the compost pile.
Hope that clears the air.
