From the Guidelines

For an 11-year-old with multiple insect bites with scabs, I recommend a combination of gentle cleansing, topical treatments, and prevention of infection, as most insect stings cause transient localized reactions that are of little serious medical consequence and do not require antibiotic therapy unless signs of infection are present 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 (5-10mg once daily) or diphenhydramine (12.5-25mg every 6 hours, not exceeding 75mg daily) can help control itching 1. Some key points to consider in the management of insect bites include:

  • Prevent scratching by keeping fingernails short and clean, and consider covering scabs with adhesive bandages.
  • If signs of infection develop (increasing redness, warmth, swelling, pus, fever), or if the bites don't improve within a week, consult a healthcare provider.
  • Fire ant stings typically cause a sterile pseudopustule within 24 hours after a sting, which should be left intact and kept clean to prevent secondary infection 1.
  • The use of oral corticosteroids may be effective in limiting swelling in patients with a history of large local reactions, although there are no controlled studies to support this 1. It's essential to note that the evidence from 1 regarding antibiotic therapy for skin and soft-tissue infections is not directly applicable to this scenario, as the patient's condition is related to insect bites rather than animal or human bites. However, it's crucial to monitor for signs of infection and seek medical attention if necessary, as the treatment for skin and soft-tissue infections may involve antibiotics such as dicloxacillin, cephalexin, or vancomycin, depending on the severity and causative organism of the infection 1.

For an 11-year-old with multiple insect bites with scabs, the recommended treatment with bacitracin (TOP) is to:

  • Clean the affected area
  • Apply a small amount of the product (equal to the surface area of the tip of a finger)
  • Apply 1 to 3 times daily
  • The area may be covered with a sterile bandage 2

From the Research

Treatment Options for Insect Bites

  • For an 11-year-old with multiple insect bites with scabs, treatment options are largely based on expert opinion and clinical experience due to a lack of evidence for the efficacy of available treatments 3
  • Simple insect bites can be managed with over-the-counter (OTC) preparations, including antihistamines and topical corticosteroids, although their effectiveness is not well-documented 3
  • Potential consequences of insect bites include local reactions, immune (allergic) reactions, and secondary bacterial infections, such as impetigo or cellulitis 3

Considerations for Management

  • The management of simple insect bites, excluding those that cause anaphylactic shock or systemic infection, is primarily focused on alleviating symptoms and preventing secondary infections 3
  • Given the lack of evidence-based treatments, healthcare professionals often rely on clinical experience and expert opinion to guide treatment decisions for insect bites 3
