You wake up with a red bump.
It itches, stings, or burns.
But was it a mosquito? A spider? Bed bugs?
Knowing the difference isn’t just about comfort — it’s about safety.
Some bug bites are harmless. Others can carry disease, cause allergic reactions, or signal an infestation.
Let’s break down 10 of the most common bug bites, how to identify them, what they feel like, and when you should see a doctor. 
How to Identify Bug Bites: Key Clues
When trying to ID a bite, ask:
Where is it? (Arms, legs, scalp, waistline?)
Pattern? (Single, clustered, in a line?)
Symptoms? (Itchy, painful, swollen?)
Timing? (While sleeping? After hiking?)
Now, let’s match the bite to the bug.
