The best natural remedy for insect stings is a raw onion.
The best natural remedy for insect stings is to cut an onion in half and apply it right to the sting. After a few moments of slightly sharper stinging, the pain will diminish almost immediately, and the sting will heal in a short while. This home remedy for bee, wasp and bumble bee stings works. I always keep an onion in my first aid kit when traveling, camping, etc.
