Allergic reactions after mosquito bites?
Hello Dr.
Jiang: My young daughter always develops small blisters and breaks the skin after being bitten by mosquitoes.
After the wounds heal, there are deep hyperpigmented spots.
I have a few questions for you: 1.
I prefer not to apply mosquito repellent because it feels greasy and uncomfortable.
Are there other mosquito prevention tools? I've heard about electromagnetic mosquito repellent devices; do you think they are effective? Are there any other precautions I should take? 2.
If she still gets bitten, are there topical medications available to relieve itching? 3.
Can applying ammonia neutralize mosquito bites? If so, what concentration is recommended? Best Regards.

There is a type of mosquito repellent device on the market that uses sound waves.
It comes in two forms: stationary and portable.
It may help prevent some mosquito bites, and if bitten, a topical corticosteroid can be applied.
My son uses this method, but Ammonia is not very effective against mosquito bites.
Wishing you peace, Jesus loves you.

More Info
Managing mosquito bite allergies in children can be a challenging task, especially when the child experiences severe reactions such as blistering and hyperpigmentation after bites. Here’s a comprehensive guide addressing your concerns and providing effective solutions and tips.
1. Alternative Mosquito Repellents
If you prefer not to use traditional mosquito repellents due to their oily texture, there are several alternatives you can consider:
- Physical Barriers: Using mosquito nets over cribs or play areas can provide a safe space for your child. Additionally, dressing your child in long sleeves and pants can help minimize exposed skin.
- Natural Repellents: Essential oils like citronella, eucalyptus, and lavender can be used in diffusers or diluted in carrier oils for topical application. However, always perform a patch test to ensure your child does not have a sensitivity to these oils.
- Electromagnetic Mosquito Repellents: These devices claim to repel mosquitoes using sound waves or electromagnetic fields. However, scientific evidence supporting their effectiveness is limited. If you choose to use one, ensure it is from a reputable brand and monitor its effectiveness in your environment.
2. Topical Treatments for Itching
If your child does get bitten, there are several topical treatments that can help alleviate itching and discomfort:
- Hydrocortisone Cream: A mild over-the-counter corticosteroid cream can reduce inflammation and itching. It’s generally safe for children when used as directed.
- Calamine Lotion: This soothing lotion can help relieve itching and dry out any blisters that may form.
- Antihistamine Creams: Products containing diphenhydramine can help reduce itching and swelling. However, be cautious with usage, especially around sensitive areas like the face.
- Cold Compresses: Applying a cold compress to the affected area can provide immediate relief from itching and reduce swelling.
3. Ammonia for Mosquito Bites
Ammonia is sometimes suggested as a home remedy for insect bites due to its alkaline properties, which can neutralize the acidic components of insect venom. However, it is not commonly recommended for children due to potential skin irritation and the risk of accidental ingestion. If you consider using ammonia, it should be highly diluted (typically around 5-10% concentration) and applied with caution. However, safer alternatives like the ones mentioned above are generally preferred.
Additional Tips
- Avoid Scratching: Encourage your child not to scratch the bites, as this can lead to secondary infections and worsen hyperpigmentation. Keeping nails trimmed can help minimize damage if they do scratch.
- Moisturize: Regularly moisturizing your child’s skin can help maintain its barrier function and reduce the likelihood of severe reactions to bites.
- Consult a Pediatrician: If your child frequently experiences severe reactions to mosquito bites, it may be beneficial to consult a pediatrician or an allergist. They can provide tailored advice and may recommend allergy testing or prescription treatments if necessary.
- Monitor for Infections: If the bite area becomes increasingly red, swollen, or shows signs of pus, it may indicate an infection, and you should seek medical attention promptly.
In conclusion, managing mosquito bite allergies in children involves a combination of preventive measures, effective topical treatments, and careful monitoring of reactions. By employing these strategies, you can help your child enjoy the outdoors while minimizing discomfort from mosquito bites. Always consult with a healthcare professional for personalized advice and treatment options tailored to your child's specific needs.
