I have discovered that bumble bees have been entering behind the siding on my house and have decided to live in the wall in my garage wall. We have begun to caulk the bottom of the siding to prevent them from going in. Any suggestions on how to kill the bees (black w/yellow stripes & fuzzy) without calling an exterminator?
There are excellent articles at http://www.bugspray.com that address bumble bees and the similar looking carpenter bee. The articles should have enough information to help you identify your problem and they provide access to the best pesticides available to pros or consumers. I have been very satisfied with purchases (and great information) from BugSpray. http://www.bugspray.com/articles99/bumblebees.html
