What are bug bites and stings?Bites or stings from insects or bees are very common and usually harmless. In some cases, an insect bite or sting can cause an allergic reaction or transmit diseases to a human.
Causes of bug bites and stings

Symptoms of bug bites or stings
Symptoms of bites or stings vary depending on the insect or bee that bit or stung you. Bites or bee stings from wasps, hornets and fire ants can be painful, turn red and potentially become inflamed.Insect bites from mosquitoes, fleas or mites typically are itchy, red, mildly inflamed and cause mild irritation.
