Yellow jackets in the underbelly

[pappy19]

If the dog flea collars repel ticks they will also repel other bugs, etc. I started using them in my permanent deer hunting huts to keep the wasps away. Works great, also repels wako anti-hunters as well.

I think the Shell no pest strips from the 1970's would work great.

Thank you for all you wonderful and funny suggestions for dealing with our bee problem in the under belly of our Airstream. We did get the wasp spray as suggested and stuffed the hole with a rag. One bee did try to get in but died on the rag. The end of the bees!!! We are very grateful to you all!!
