To identify an insect bite, a patient should determine the intensity of the pain or itch, swelling of the bite site and symptoms of diseases that relate to the insects, claims Everyday Health. Identification of the bite aids in deciding the appropriate treatment.
A mosquito or bed bug bite appears as a red or pink skin bump that irritates, explains Everyday Health. Symptoms of these bites include swollen glands, headaches, body aches and a skin rash that usually manifest after 15 days. Bed bug bites do not hurt instantly, but cause inflammation and irritation after at least 24 hours.
Bee stings and ant or spider bites cause pain, swelling and red or white skin, notes Everyday Health. The sting of a bee is sharp and fades after a short while, with the bite site feeling hot to touch. Symptoms of a spider bite includes trouble in breathing, difficulty swallowing and swelling of the face. Poisonous spiders such as the brown recluse and black widow may or may not cause a sharp pain instantly, but swelling occurs four to eight hours later.
A tick bite appears as a skin rash in pattern of rings, states Everyday Health. A red skin rash, hives and itching or swelling around an injury are symptoms of a flea bite. Lice bites are so small that they don't hurt, but they itch a lot just like mite bites. Scabies mite bites cause skin rashes that resemble acne, but they itch a lot and usually occur in folds of the skin.
