Yellow bees ( aka some sort of wasp)
Ditto on the Mountain Dew. They are also attracted to fat, meat. I've seen homemade traps made of bacon grease and pop (ew)
-Keep a CLEAN camp. they like food.
-Do not leave open drinks laying around. They like to crawl inside.
-You can buy traps at any hardware store.

Keep benadryl in your first aid kit.
