Yellow vented hornets are large social wasps that form organized colonies. They build papery nests by chewing wood fibers and mixing them with saliva. These insects are known for their defensive behavior when their nest is disturbed.

A hornet sting produces immediate pain and a burning sensation. The initial reaction may include swelling redness and itching around the sting site. Some individuals experience more serious effects such as dizziness difficulty breathing or widespread swelling in the hours after a sting.

  • Apply a cold compress to the sting for up to fifteen minutes to reduce swelling.

  • Do not rub or scratch the area to prevent irritation.

  • Seek immediate medical help if there are signs of a severe reaction such as trouble breathing or swelling of the face or tongue.
