My hive made it through the winter and they look great. I've been feeding them for the past month, or since I've seen them flying. I didn't treat them for mites last year at all, but I think I should do it this spring. Saw a few dead mites under the screened bottom board and I suspect there will be more coming. Planning to use Mite-Away Quick Strips. When do you think would be a good time to do this? I'm in central Ontario - our weather has just started warming up - no dandelions yet but I think they'll bloom in a couple of weeks. Trees are just starting to bud. I don't want to treat too soon but also don't want to wait until it's too late. Advice, please.
