What can i do for a wasp bite very itchy?

Hydrocortisone OTC: The easiest way is to apply over-the counter 0.25% Hydrocortisone cream. And try to avoid the wasps, of course... Good luck.

I believe that most : Wasps sting (but a yellow jacket can both bite ; sting). Wash area w soap ; warm water. Apply ice in 10 min. Increments (10 on/10 off). Can try tylenol, (acetaminophen) Aspirin or Motrin for pain or Benadryl for swelling / itching. Elevate affected area for swelling. Make paste of 2 parts baking soda ; 1 part water ; apply. Need tetanus shot every 10 years. Throat, airway, mouth swelling or difficulty breathing.
