Bees, wasps, hornets, and yellow jackets can all sting. Most stings are caused by yellow jackets.
Stings cause painful red bumps right away.
Most of the time, the pain is better in a couple of hours. The sting could keep swelling for 24 hours. If your child was stung many times, your child may vomit or have diarrhea, a headache, and a fever. This is because of the large amount of venom from the stings. Stings can also cause an allergic reaction.
