Fire ants are notorious for causing severe local reactions, including pustules or pimples and red, swollen, and extremely itchy areas, which may turn into blisters. They often bite multiple times, most commonly on the feet and legs. A large number of bites, more than 10-20, in a young infant can lead to serious reactions and may require medical attention. Bees, wasps, yellow jackets, and hornets usually cause painful red bumps.
Honey bees have a barbed stinger and usually leave it behind at the site of the sting.
The stinger will usually appear as a black dot inside the bite if it has been left behind. More serious local reactions can cause swelling of an entire limb. Unlike other bites, tick bites are painless and usually don't itch. Bedbugs also usually cause painless bites, which then become itchy. Chiggers or harvest mites also commonly bite children, especially in the southern United States, where they are found in grasses and bushes.
