Insect Bite

Disponible En Espanol


Care at Home

  • ITCHY INSECT BITES: * STEROID CREAM. To reduce the itching, use 1% hydrocortisone cream. No prescription is needed.  Put it on 3 times a day until the itch is gone. If you don't have, use a baking soda paste until you can get some. * If neither is available, use ice in a wet washcloth for 20 minutes. * Also, you can put firm, sharp, direct, steady pressure on the bite. Do this for 10 seconds to reduce the itch.  A fingernail, pen cap, or other object can be used. * ALLERGY MEDICINE. If the bite is still itchy, try an allergy medicine such as Benadryl. No prescription is needed. Sometimes it helps, especially in allergic children. See Dose Table.
  • PAINFUL INSECT BITES: * Soak a cotton ball in a baking soda solution. Rub the bite with it for 15 to 20 minutes. Do this once. This will usually reduce the pain. * You can also use an ice cube in a wet washcloth for 20 minutes. * To help with the pain, give acetaminophen (such as Tylenol) or ibuprofen. Use as needed. See Dose Table. * For painful bites, allergy medicines don't help.
  • WHAT TO EXPECT: * Most insect bites are itchy for several days. * Any pinkness or redness usually lasts 3 days. * The swelling may last 7 days. * Insect bites of the upper face can cause severe swelling around the eye. This is harmless. * The swelling is usually worse in the morning after lying down all night. It will improve after standing for a few hours.
  • CALL YOUR DOCTOR IF: * Severe pain lasts more than 2 hours after pain medicine * Infected scab not better after 48 hours of antibiotic ointment * Bite looks infected (spreading redness gets bigger after 48 hours) * Your child becomes worse
  • PREVENTION: * Wear long pants, a long-sleeved shirt and a hat. * Avoid being outside when the bugs are most active. Many insects that cause itchy bites are most active at sunrise or sunset. Examples are chiggers, no-see-ums, and mosquitoes. * Insect repellents that contain DEET are helpful in preventing many insect bites. Read the label carefully.
  • DEET PRODUCTS: Use on the skin. * DEET is a very effective bug repellent. It also repels ticks and other insects. * The AAP approves DEET use over 2 months of age. Use 30% DEET or less. Use 30% DEET if you need 6 hours of protection. Use 10% DEET if you only need protection for 2 hours. (AAP 2003). * Don't put DEET on the hands if your child sucks on their thumb or fingers. (Reason: prevent swallowing DEET.) * Warn older children who apply their own DEET to use less. A total of 3 or 4 drops can protect the whole body. * Put it on exposed areas of skin. Do not use near the eyes or mouth. Do not use on skin that is covered by clothing. Don't put DEET on sunburns or rashes. Reason: DEET can be easily absorbed in these areas. * Wash it off with soap and water when your child comes indoors. * Caution: DEET can damage clothing made of man-made fibers. It can also damage plastics (such as eye glasses) and leather. DEET can be used on cotton clothing.
  • PERMETHRIN PRODUCTS: Use on clothing. * Products that contain permethrin work well to repel insects and ticks. Examples of these products are Duranon or Permanone. * Unlike DEET, these products are put on clothing instead of skin. * Put it on shirt cuffs, pant cuffs, shoes and hats. * You can also use it on other outdoor items (mosquito screens, sleeping bags). * Do not put permethrin on the skin. Reason: Sweat changes it so it does not work.
  • PICARIDIN PRODUCTS: * Picaridin is a repellent that is equal to 10% DEET. * It can safely be put on skin or clothing.
  • WHAT YOU SHOULD KNOW: * Most insect bites cause a red bump. Some are larger (like a hive). Some have a small water blister in the center. These are normal reactions to an insect bite. * A large hive at the bite does not mean your child has an allergy. * The redness does not mean the bite is infected. * Here is some care advice that should help.
  • ANTIBIOTIC OINTMENT: * If the insect bite has a scab on it and the scab looks infected, use an antibiotic ointment. An example is Polysporin. No prescription is needed. Use 3 times per day. (Note: Usually impetigo is caused by scratching with dirty fingers). * Cover the scab with a Band-Aid to prevent scratching and spread. * Wash the sore and use the antibiotic ointment 3 times per day. Cover it with a clean Band-Aid each time. Do this until healed. * Caution: For spreading infections (redness or red streaks), your child needs to be seen.
