Keep Kids Safe from Bugs Many products seek to prevent bug bites, but products containing DEET (usually listed on labels as N,N-diethyl-m-toluamide) are quite effective. Children and Fleas, Mites, and Chiggers Fleas, mites, and chiggers often bite humans, but aren't poisonous. It's sometimes difficult to assess which type of insect caused the bite, or if the rash is caused by poison ivy or other skin conditions. Tick Bites Ticks attach themselves to the scalp, behind the ear, in the armpit and groin, and also between fingers and toes. Tick bites often occur at night and are more common in the spring and summer months. Lyme Disease in Children Lyme disease is the leading cause of all insect-borne illness in the United States. It is a year-round problem, although April through October is considered tick season. Rocky Mountain Spotted Fever in Children This infection is caused by a tick bite. Common symptoms are fever and a non-itchy rash that usually starts on the hands, arms, feet, and legs seven to 10 days after the bite. Spider Bites in Children In the United States, two spiders that can cause serious problems are the black widow and the brown recluse spiders. Both of these spiders are found in warm climates. Insect Stings and Allergic Reactions For most children, the reaction to a sting is short-lived, with redness and swelling followed by pain and itching. For others, however, the allergic reaction to an insect sting can be life threatening. Snake Bites and Children Treat all bites as if they were from a venomous snake and get your child to a hospital emergency room as quickly as possible.
