To identify a bug bite, individuals should evaluate the size and color of the bite mark as well as the intensity of the pain and diseases that occur as a result of the bite, according to HealthCentral. Different bugs have bites that cause different symptoms.
A fire ant's bite is red at the center with lighter colored rings, as HealthCentral explains. Symptoms of this bite include pain, nausea, fever and fatigue. Bed bug bites appear in circles that are arranged in order, form red bumps that disappear after a few days and may lead to skin redness, itching and swelling.
Tiny rashes in the armpits or joints that may spread to the surrounding areas indicate a flea bite, explains HealthCentral. A mosquito bite causes serious itching that results to swelling and a red bump. A chigger bite is painless, but it may cause a red, itchy bump.
A tick bite may cause Lyme disease, and it may lead to muscle aches, swollen lymph nodes, fever and headaches that occur some weeks later, according to HealthCentral. The bite of a black fly itches and causes instant pain, which may last for some time, and scratching the bite may result in an infection.
A brown recluse's bite, which is painless, appears first as red and then turns white, and it may develop into a blister that resembles a bullseye, according to HealthCentral. The bite of a black widow, however, is sharp and appears as two dots. It may cause a person to experience aggravated blood pressure, nausea or immediate vomiting.
