I was pulling off some supers and saw a few hive beetles. I live in Southern Michigan. I see the idea of taking political signs and greasing the ends with crisco and putting some boric acid in them and stapling them in the bottom and top of the hive? Would you recommend this. Is there a risk to the bees? Is the chance of the beetles being a problem less in the fall. I am told you can treat the ground in the spring to prevent them from reemerging. Don't want to throw out the baby with the bathwater?
