Insect Bite Identifier

How to Identify Insect Bites and Stings

Identifying the source of a bite or sting quickly is essential — different insects require completely different treatment approaches. Most bites from mosquitoes, ants, and fleas are harmless and resolve within days. However, bites from spiders, ticks, and stings from bees or wasps may require prompt medical attention, especially in individuals who are allergic.

Key visual indicators our AI looks for include: the number and pattern of marks (single vs. clusters or rows), the shape and color of the welt, whether a stinger or tick remains embedded, and the appearance of the surrounding skin reaction. The more clearly you can photograph these features, the more accurate the identification will be.

When Is an Insect Bite a Medical Emergency?

Call emergency services immediately if you or someone nearby experiences difficulty breathing or swallowing, swelling of the face, lips, throat, or tongue, a rapid or irregular heartbeat, severe dizziness or fainting, a widespread rash or hives across the body, or loss of consciousness after a sting or bite. These symptoms indicate anaphylaxis — a potentially fatal allergic reaction that requires immediate epinephrine (EpiPen) treatment and emergency medical care.

Tick Bites and Lyme Disease — What to Know

For tick bites, watch carefully for a bull's-eye rash (erythema migrans) in the days following the bite — this circular red rash expanding outward from the bite site is a hallmark sign of Lyme disease that requires immediate antibiotic treatment. Early-stage Lyme disease is highly treatable, but if left untreated it can cause serious joint, heart, and neurological complications. See a doctor within 48 hours of any tick bite for proper evaluation and testing.
