What is the proper first aid for yellow jacket stings?

Unnecessary: First aid isn't usually necessary unless you're allergic.

1st aid: Clean area with soap ; warm water. Apply ice in 10 minute increments; alternating 10 on ; 10 off. Try a bag of cold peas. You can take meds like tylenol, (acetaminophen) Aspirin or Motrin for pain or Benadryl for swelling. Make a paste of 2 parts baking soda ; 1 part water ; apply. Need tetanus shot every 10 years.
