Why it's different
Most bite identifiers ask for a photo of the insect — the one thing you almost never still have after you've been bitten. Bug Bite & Sting Identifier starts from the bite on your skin, the thing you actually have, and pairs every result with responsible next-step guidance instead of a scary guess.
Educational only — not a diagnosis
Bug Bite & Sting Identifier is an educational identification tool, not a medical diagnosis or treatment. Every result reminds you to see a doctor. If symptoms worsen, or you suspect a serious allergic reaction or infection, seek medical care or call your local emergency number.

How to identify a bug bite from a photo
You've been bitten, the bug is long gone, and you're left staring at a red mark. Here's how to read the bite itself — the pattern, location, and symptoms — to narrow down the likely culprit.
Mosquito vs. bedbug vs. flea bites
Itchy red bumps from mosquitoes, bedbugs, and fleas look alike at a glance — but their pattern, location, and timing usually give them away. Here's how to tell which is which.
Tick bites and Lyme disease: what to watch for
Tick bites are often painless and easy to miss — which is exactly why they deserve attention. Here's how to recognise one, remove a tick safely, and spot the warning signs of Lyme disease.
