Insect bites and stings are mild and can be treated at home. Some might cause itching, swelling, and stinging that will go away in a day or two. To help relieve the effects of the sting or bit, apply a cloth dampened with cold water or ice to the effected area for about 10 to 20 minutes. Have fun as you complete the series of puzzles and learn more about stings, bites, and reactions.
