From the Guidelines
For an 11-year-old with multiple insect bites with scabs, I recommend a combination of gentle cleansing, topical treatments, and oral medications if needed, as most insect stings cause transient localized reactions that are of little serious medical consequence and do not require antibiotic therapy unless there are signs of infection 1. To manage the symptoms, clean the affected areas daily with mild soap and water, then apply an over-the-counter antibiotic ointment like Bacitracin or Polysporin to prevent infection. For itching, use 1% hydrocortisone cream up to twice daily for no more than 7 days, as oral antihistamines like cetirizine (Zyrtec) 10mg once daily or diphenhydramine (Benadryl) 25-50mg every 6 hours can help control itching 1. Some key points to consider include:
- Prevent scratching by keeping fingernails short and clean, and consider having the child wear light cotton gloves at night.
- Cool compresses can provide additional relief.
- If the child has signs of infection such as increasing redness, warmth, swelling, or pus, consult a healthcare provider promptly, as the decision to administer oral or parenteral antibiotics depends on the depth and severity of the wound and on the time since the bite 1. The treatment approach should focus on reducing inflammation, preventing bacterial infection of the broken skin, and blocking histamine receptors that cause itching, allowing the bites to heal properly while preventing secondary complications. It is essential to note that fire ant stings typically cause a sterile pseudopustule within 24 hours after a sting, and the vesicle should be left intact and kept clean to prevent secondary infection 1.

From the Research
Treatment Options for Insect Bites with Scabs
- For an 11-year-old with multiple insect bites with scabs, treatment options may include topical antibiotics such as mupirocin, retapamulin, and fusidic acid, as these are effective against bacterial infections that can occur in insect bites 3.
- In some cases, oral antibiotic therapy may be necessary, with options including amoxicillin/clavulanate, dicloxacillin, cephalexin, clindamycin, doxycycline, minocycline, trimethoprim/sulfamethoxazole, and macrolides 3.
- However, it's essential to note that the management of simple insect bites lacks strong evidence, and many treatments are based on expert opinion and clinical experience 4.
- For mosquito bites specifically, treatments such as cetirizine and levocetirizine have been shown to decrease the size of wheals and pruritus in some studies 5, 6.
Considerations for Treatment
- The increasing prevalence of antibiotic-resistant bacteria, including methicillin-resistant S. aureus, macrolide-resistant streptococcus, and mupirocin-resistant streptococcus, should be considered when selecting a treatment option 3.
- Topical disinfectants are generally inferior to antibiotics and should not be used as a primary treatment for insect bites with scabs 3.
- Counseling patients on proper use of insect repellents and good first aid techniques can help reduce the risks associated with insect bites 7.
