I have had issues with Yellowjackets building their nest in my front storage compartment and my propane bottle compartments. These are open to the outside and the wasps really like the covered and protected enclosure. I can't say I blame them. I found a solution I would like to pass along.
I buy 3 of the Hot Shot Pest Strips off of Amazon. They are bit over $6 each and they last an entire season. Simply hang one in each of the compartments that are open to the outside. Problem solved! No wasps, no spiders, no anything!
