Bees under flooring under trailer...

Thxs I will keep you posted after we get to campground tomorrow! I was thinking the vacuum too ; )
Next step is amazon one!! Thanks again!

I had them in the walls of my house a couple times, blasted the entry point with powdered bee and spider killer at night. Took a couple days but it worked like a champ.

Not this brand but very similar.

I use a shop vac to handle wasps and bees. Just prop the suction hose at the point of entry/exit and let the vacuum suck them up as they come and go. In 30 to 60 minutes or so the problem is solved. When you shut down the vacuum plug to hose off and leave sit for a day or so.
