I was wondering what to use to prevent bees from returning to the site of their hive. I have only done one "cutout" and it was tons of work. Much more than the worth of the results. I definitely learned a bunch, but my unanswered question is above. How can I prevent, or at least deter, the bees from reestablishing their colony there? Obviously cutting out everything is a step, but is there a chemical or anything with which I could treat the area?
I swore I was done with "cutouts", but this couple really wants the bees gone. They want them removed, not exterminated. I appreciate this thought and want to oblige them. They also are willing to pay, which makes it worthwhile. I just don't have the time to commit to a "cutout" for free. I want to do these folks right with as much prevention as possible. Any thoughts?
