After a day outside, you spot red, swollen bumps on your baby’s arms and face. Baby skin often reacts more strongly to bites than adult skin, which can look worrying. Most insect bites on babies are harmless and settle within a few days with simple care. Here is how to treat them, prevent them and spot the rare signs that need help.
Quick answer: insect bites on babies
- Most bites cause a red, itchy bump that fades in a few days.
- Treat with washing, a cold compress and keeping nails short to stop scratching.
- Prevent with covering clothing, nets and avoiding peak insect times.
- Seek emergency help for swelling of the face or lips, hives all over or breathing difficulty.
Common bites and stings
- Mosquitoes: small, itchy red bumps on exposed skin.
- Fleas: clusters of small bites, often on the legs and waist, sometimes linked to pets.
- Bed bugs: bites in lines or groups, often appearing overnight.
- Bees and wasps: painful, swollen sting; a bee may leave its sting behind.
- Ticks: a small dark bug attached to the skin.
How to treat a bite
- Wash the area with soap and water.
- Apply a cold compress wrapped in a cloth for 10 minutes to reduce swelling.
- Remove a bee sting by scraping it sideways with a fingernail or card.
- Remove a tick with fine tweezers, gripping close to the skin and pulling steadily upwards.
- Keep nails short and use mittens if your baby scratches.
- Ask your pharmacist before using any cream or antihistamine on a baby.
Preventing bites
- dress your baby in light, long sleeves and trousers outdoors
- use mosquito nets on prams, cots and travel cots
- avoid dawn and dusk near water, when mosquitoes are most active
- check pets for fleas and treat them regularly
- check your baby for ticks after walks in long grass or woods
- ask your doctor before using insect repellent on babies; many products are not suitable under 2 months
When to talk to your doctor
- swelling of the lips, tongue or face, wheezing or breathing difficulty: call emergency services
- hives spreading over the body, or vomiting after a sting
- redness that spreads, feels hot, or oozes pus (possible infection)
- a red ring or rash around a tick bite, or fever in the weeks after
- many bites, or bites near the eyes or mouth
Frequently asked questions
Why do bites look so big on my baby?
Young children often react more strongly to insect saliva. Large, itchy swellings are common and usually not an allergy.
Can I use adult bite cream?
Check with your pharmacist first; many products are not licensed for babies.
Is it a bite or a rash?
Bites usually appear on exposed skin and in small numbers. See baby rashes.
