I've used it in the past with great success. Recently I've noticed alot of bees going in under the siding on my house. I've applied the dust multiple time over the last few weeks and the bees are still entering and leaving. Im not sure what type of bees they are.
The Delta Dust will work on any type of bee, but they may be further up in the void than the dust is reaching. Or they may have another exit point you can't see at the moment, or just a large colony in general. You can give it a few more weeks or potentially try a transfer spray like Phantom Aerosol which is a very slow kill but gets carried through the nest through touch a little better, in this case.
