Camping & bees

We're headed out camping this afternoon and I stopped by WINCO to pick up a few things before we go.  I went down the seasonal aisle looking for zinc oxide sunscreen and didn't find any :(  But I did find yellow jacket traps and I knew we needed another one for the back yard (1 isn't cutting it) and I thought it would be a good idea to buy one for camping.  Bees are usually hanging around when there's food, and I don't want any of us to get stung.  They were $4.88/each and I hope to catch many of those little buggers this weekend!

Do you have bothersome yellow jackets in your yard?  How do you keep pests away while camping?
