I discovered a nest of big, fuzzy bumble bees while cleaning out my garage. My garage was built in the 1930’s and has a wood floor. The nest is in /under a gap between 2 boards near the outside wall. What is the best way to kill them and the nest since the floor boards cannot be moved?
If you read through our online BUMBLEBEE CONTROL ARTICLE, you’ll see this type of a space is a common location for this type of bee to use for nesting. In the article we also list a product known as DELTAMETHRIN DUST. This would be ideally suited for your problem. The Deltamethrin Dust should be applied through all the gaps you see using a HAND DUSTER. Once treated let the area sit for a day or two. As the bees travel through gaps they’ll be picking up subtle amounts of the dust. This will in turn cause them to die. Within a 2-3 days the nest should be shut down but if you still find activity after then, dust some more.
