Insect bites in babies: prevention and when to worry

Insect bites are often more irritating than dangerous, but in babies they should be prevented carefully and watched well. The goal is to reduce bites without using products incorrectly.

First barrier: environment and clothing

Before products, use physical measures:

• mosquito net over stroller or crib when appropriate;
• light but covering clothes;
• socks if ankles and feet are exposed;
• standing water removed from saucers and buckets;
• intact window screens;
• walks away from heavily infested areas when possible.

Do not apply essential oils or home remedies to a baby's skin.

Repellents

For young babies, ask your pediatrician before using repellents. If a product is appropriate for your child's age:

• read the label;
• apply only the amount needed;
• avoid hands, eyes, mouth and irritated skin;
• do not spray directly on the face;
• apply in a ventilated area;
• wash it off when no longer needed.

Keep repellents out of children's reach and do not use sunscreen + repellent combination products unless specifically advised.

After a bite

If a bite appears:

• gently wash the area;
• avoid scratching or rubbing;
• keep nails short;
• watch size, color and local warmth;
• do not apply medicines, numbing creams or steroids without advice.

A small red area can appear, but it should improve rather than worsen.

Ticks

After grass, woods or animal contact, check skin folds, scalp, behind ears, armpits, groin and behind knees. If you find a tick, ask for health guidance on removal and monitoring, especially in babies.

When to call

Seek urgent care for breathing difficulty, swelling of lips or face, widespread hives, unusual sleepiness, repeated vomiting or rapid worsening.

Contact the pediatrician if the area becomes very swollen, hot, painful, has pus, fever, red streaking or if your child is very young and you are unsure what to apply. If your child swallows or sprays repellent on themselves, call poison control or your local emergency number.

Key takeaway

For a baby, the best prevention is physical: nets, clothing and a controlled environment. Repellents should be age-appropriate and used sparingly.
