Insect Bites and Stings in Children: Treatment and Prevention

Summer means outdoor play, romping in the grass, and long evenings outside. But it also means mosquitoes, wasps, ticks, and other insects that can bite or sting the little ones. Children often react more strongly to insect bites than adults, and it can be hard to know what's normal and what requires medical attention.

Here's a complete overview of the most common insect bites and stings in children, how to treat them, and when you should see a doctor.

Mosquito Bites in Children

Mosquitoes are the most common insects that sting children. The bites are irritating and itchy but rarely dangerous.

Symptoms

• Red, swollen bump that itches intensely
• Can become quite large in children (1–2 inches in diameter)
• Itching is worst in the first hours but can last several days
• Children who have never been bitten before may react more strongly

Treatment

1. Cool down — apply a cold, damp cloth or ice pack (wrapped in a towel) to the bite for 10–15 minutes
2. Anti-itch cream — hydrocortisone cream 1% can be used from age 2. For younger children: ask the pharmacist for a suitable alternative
3. Prevent scratching — keep the child's nails short, and use mittens at night for the youngest
4. Antihistamine — cetirizine drops can be used from 6 months of age for severe itching. Follow the dosing on the package
5. Aloe vera gel can provide relief and is safe for most children

When Is a Mosquito Bite Dangerous?

Mosquito bites can become infected if the child scratches a lot. Signs of infection include:

• Increased redness that spreads
• Warmth and swelling that increases after 2–3 days
• Pus or fluid from the bite
• Fever
• Red streaks from the bite

Contact a doctor if you see signs of infection.

Wasp Stings in Children

Wasp stings are more painful than mosquito bites and can in rare cases cause serious allergic reactions.

Symptoms

• Immediate, sharp pain at the sting site
• Redness and swelling around the sting
• Itching that develops over hours
• Children who have never been stung often have a stronger local reaction

Treatment

1. Remove the stinger if it's still in place (wasps rarely leave a stinger, but bees do). Scrape the stinger out with a fingernail or card — don't squeeze with fingers
2. Wash the area with soap and water
3. Cool down with an ice pack wrapped in a towel
4. Pain relief — acetaminophen in age-appropriate dose
5. Anti-itch — hydrocortisone cream 1% or antihistamine as needed

Allergic Reaction — What You Need to Know

Most children only get a local reaction. But some can develop a severe allergic reaction (anaphylaxis). This is rare but can be life-threatening.

If the child has a known bee or wasp allergy, they should always have an epinephrine auto-injector (EpiPen) available. Talk to your pediatrician about an action plan.

Bee Stings in Children

Bee stings are similar to wasp stings, but bees leave their stinger in the skin.

Important Difference from Wasps

• The bee leaves its stinger with venom sac in the skin
• Remove the stinger quickly — the longer it stays, the more venom is released
• Scrape the stinger out sideways with a fingernail, bank card, or knife edge
• Don't squeeze the stinger — that pushes out more venom

Treatment after the stinger is removed is the same as for wasp stings.

Tick Bites in Children

Ticks are widespread in many regions and can transmit Lyme disease and, in some areas, tick-borne encephalitis (TBE).

How to Remove a Tick

Proper tick removal is important to reduce the risk of infection:

1. Use tick tweezers or a tick card — available at pharmacies
2. Grasp the tick as close to the skin as possible
3. Pull straight out with a steady, gentle pull. Don't twist
4. Check that the entire tick came out — make sure the head isn't left behind
5. Wash the area with soap and water
6. Disinfect with rubbing alcohol

What NOT to Do

• Don't use butter, petroleum jelly, alcohol, or fire to make the tick release — this can cause the tick to empty its stomach contents into the wound and increase the risk of infection
• Don't squeeze the tick body
• Don't wait — remove the tick as quickly as possible

Signs of Lyme Disease

After a tick bite, you should observe the bite site for 3–4 weeks. Signs of Lyme disease:

• Erythema migrans — a ring-shaped, red rash that spreads outward from the bite site. The rash is usually over 2 inches in diameter and may have a lighter zone in the center
• The rash is usually not painful or itchy
• It can take 3–30 days after the bite before the rash appears
• Some people also develop fever, headache, or joint pain

Contact a doctor if you see a ring-shaped rash that's growing, or if the child develops fever or other symptoms after a tick bite. Lyme disease is effectively treated with antibiotics.

TBE Vaccine

The CDC recommends checking if your area has tick-borne encephalitis and discussing vaccination with your pediatrician. The vaccine can be given from 1 year of age.

Gnats and Horseflies

Gnat Bites

• Common in wooded and mountainous areas
• Leave a small bleeding wound that itches intensely
• Can become quite swollen in children
• Treatment: cooling, anti-itch cream

Horsefly Bites

• Large, painful bites
• Can cause significant swelling, especially in children
• Rarely dangerous but uncomfortable
• Treatment: wash, cool, pain relief as needed

Preventing Insect Bites

Mosquitoes

• Insect repellent: DEET-based products are effective but should be used cautiously on children. For children under 2 years, products with lower DEET concentration (max 10%) or citronella-based alternatives are recommended. Ask your pharmacist
• Mosquito nets over strollers and beds during mosquito season
• Long, light-colored clothes cover skin and attract fewer mosquitoes
• Avoid scented products — they attract mosquitoes
• Eliminate standing water in the yard — mosquitoes breed there

Wasps and Bees

• Don't walk barefoot in the grass (bees collect nectar from clover)
• Cover food and drinks outdoors
• Keep trash cans closed
• Avoid bright colors and floral patterns on clothing
• Teach the child to stay calm around wasps — swatting provokes them

Ticks

• Check the entire body after outdoor play in woods, grass, and brush
• Especially check: scalp, behind ears, armpits, groin, behind knees
• Light, long clothes make it easier to spot ticks
• Tuck pants into socks in tick areas (not stylish, but effective)
• Tick repellent can be used on clothes, but not directly on young children's skin

When Should You See a Doctor?

Always seek medical attention if:

• The child is stung in the mouth, throat, or on the tongue (risk of airway swelling)
• The child shows signs of allergic reaction (swelling, breathing difficulty, rash all over the body)
• A ring-shaped rash appears after a tick bite
• A sting or bite shows signs of infection (increasing redness, warmth, pus)
• The child has a fever after an insect bite
• The child is under 3 months and is stung by a wasp or bee
• You're unsure

Frequently Asked Questions

Is insect repellent safe for babies?

For children under 2 months, it's recommended to use mosquito nets instead of insect repellent. For children over 2 months, mild products can be used, but avoid DEET concentrations over 10%. Never apply repellent to children's hands (they put their hands in their mouths). Ask the pharmacist for age-appropriate products.

What do I do if the tick head remains in the skin?

Don't worry. If the head remains, the body will usually push it out on its own. Wash the area and observe. Contact a doctor if it becomes red, swollen, or infected. Don't dig for the head with a needle — that increases the risk of infection.

Can children become immune to mosquito bites?

No, but children can develop a milder reaction over time. Young children bitten for the first time can get large, swollen bumps. After repeated bites over several seasons, the reaction often becomes milder.

Should I take my child for an allergy test after a wasp sting?

If the child had a severe reaction (breathing difficulty, swelling far from the sting site, dizziness), they should be referred to an allergist. A normal local reaction — even if it's large and swollen — usually doesn't require testing.

Are there natural insect repellents that are safe for children?

Citronella and lemongrass-based products are mild alternatives but are less effective than DEET. Lavender and chamomile may have some repelling effect. For best protection in tick areas, a pharmacy product is still recommended.

How do I know if it's a mosquito, gnat, or tick bite?

Mosquito bite: Round, red, swollen bump with intense itching. Appears quickly. Gnat bite: Small bleeding spot, then a red bump. Very itchy. Tick bite: No pain from the bite. You find the tick attached to the skin, or a red dot after it has released.
