Mosquito Bites: Relief and Prevention

As families step back outside, gardens grow, evenings linger, and mosquitoes make their return. While these visitors can be annoying, the good news is that bites are usually harmless and rarely cause serious illness. Itching is usually the toughest part.

Caring for Itchy Bites

• Apply a mild steroid cream such as 1% hydrocortisone or Cortaid two to three times a day to reduce inflammation.
• Use Benadryl (diphenhydramine) cream to help calm itching.
• Encourage children not to scratch, as broken skin can invite infection.
• If the skin does break, a triple antibiotic ointment like Polysporin or Neosporin can help.

It’s normal for mosquito bites to itch for 3–5 days, with swelling gradually fading over 7–10 days.

Preventing Mosquito Bites

• Avoid outdoor play at dusk and dawn, when mosquitoes are most active.
• Remove standing water where mosquitoes like to breed.
• Dress smartly in mosquito-heavy areas: tuck in shirts, tuck pants into socks, and choose shoes over sandals.
• Use skin repellents when needed. Products containing DEET (up to 30%) are safe.

Using Repellents Safely

• Apply only to exposed skin, not skin covered by clothing.
• Avoid applying to cuts, scrapes, or irritated skin.
• For the face, apply repellent to your hands first, then gently spread—avoiding eyes and mouth.
• Do not apply repellents near food or in enclosed areas.
• Wash hands after applying.
• For clothing, use products containing permethrin. Let clothing dry completely and never apply permethrin directly to skin.
