Most people never notice their first mosquito bites. After being bitten several times, though, you're likely to start noticing, often almost immediately after the mosquito feeds. The signs include:
- A puffy, white bump that appears a few minutes after the bite
- A hard, itchy, reddish-brown bump, or multiple bumps, appearing a day or so after the bite or bites
- Swelling around bites
- Small blisters instead of hard bumps
- Dark spots that look like bruises
In children and people with immune system disorders, mosquito bites sometimes trigger:
- A large area of swelling and redness
- Low-grade fever
- Swollen lymph nodes
When to see a doctor
If mosquito bites seem to be associated with more-serious signs and symptoms — such as fever, headache and body aches — contact your doctor.
