The different kinds of bug bites and their identification based on the accompanying symptoms are listed below:

  • Mosquito bite identification: Mosquitoes are blood sucking bugs that can fly. The skin rash arising out of a mosquito bite is caused due to an extreme allergic reaction. Patients may experience the formation of red, itchy bruises or blisters. This bug bite can cause diseases like dengue fever, malaria, etc. Constant scratching of the blisters to alleviate itchiness can also result in secondary skin infections.

  • Bed bug bite identification: Bed bugs are typically found in hotels, apartment complexes, shelters, etc. Bed bug bites occur as sequential large wheals and the rash may be accompanied by inflammation of the affected skin, swollen bumps, or blisters. Itchiness of the rash usually commences around an hour after the bug has finished its blood feast. Bed bug bites do not cause any medical complications and usually disappear on their own in a couple of days.

  • Chigger bite identification: Chiggers are arachnids that bite on areas around warm skin creases, ankles, or waist. Chigger bite wounds appear as tiny reddish elevated lesions. Itchiness tends to occur many hours after the bug bite. Hence, the patient is usually unaware of a chigger bite. The symptoms of a chigger bite are similar to those occurring as part of an allergic reaction to contact with poison ivy.

  • Flea bite identification: A flea bite will cause tiny itchy bumps that bleed. The bump will have a characteristic solitary puncture mark in the center. The itchiness is caused due to allergic reaction to the fluids released by the bug. The bug bites may occur in groups of two and are usually inflamed. The rashes vanish only after many weeks.

  • Tick bite identification: It is regarded as the worst kind of bug bite. Ticks are carriers of varied diseases and infections. Tick bite can remain undetected for many hours, as the bite itself does not cause pain. The rash may develop only after the tick has fallen off the host’s skin, first affecting the bite area and later spreading to the rest of the body. Lyme disease caused by deer tick bite is one of the most dangerous illnesses that can be caused by a bug bite. It causes an expanding circular rash, and is often accompanied by headaches, fever, chills, swollen lymph nodes, and jointand muscle aches.Untreated cases may affect the heart, joints, and the nervous system, leading to facial paralysis, memory problems, and arrhythmia.
