Brown Recluse Spider Bite (Child)
Brown recluse spiders are most often found in the South, West, and Midwest. They may be light or dark brown. They are ¼ inch to ¾ inch long, and have long, thin, legs. Some have a fiddle-shaped mark on their back. They prefer dark places and often live indoors in cupboards, basements, or attics. They also live outdoors under rocks or trash cans. These spiders only bite when disturbed.
When a brown recluse bites, a small red mark may form at the site. Then small blisters may appear. Within 2 to 8 hours, the area may become painful, swollen, and itchy. The child may develop a fever and be restless. Other possible symptoms include upset stomach (nausea), vomiting, and muscle pain. In most cases, the bite site heals on its own within a week. But in some cases, the skin at the bite site may break down and form an open wound (ulcer). An ulcer can take from a week to a few months to heal. In rare cases, a brown recluse bite may lead to more serious problems. These can include muscle damage, kidney failure, problems with blood clotting, and coma.
The doctor will clean the bite site and give medicines to relieve pain, if needed. Antibiotics may also be given to treat infection. A tetanus shot may be given. If an ulcer forms, skin grafting may be done later to repair severe damage to the skin. But most bites heal without scarring.
Home care
Medicines may be prescribed to relieve pain or treat infection. Follow directions for giving these medicines to your child.
General care
-
Let your child rest as needed.
-
Care for the bite site as directed by your child’s doctor.
-
To ease pain and swelling, apply cold packs to the bite site as directed. Use a cool wet washcloth or an ice pack. To make an ice pack, put ice cubes in a plastic bag that seals at the top. Then wrap the bag in a thin towel. Don’t put ice directly on the skin.
-
If your child was bitten in the arm or leg, it may help to keep the body part raised (elevated) to reduce swelling.
-
Check the bite site for any unusual changes or signs of infection (see below).

Warn your child to stay away from woodpiles and other areas that attract spiders.

Teach your child to shake out clothes or blankets that have fallen onto the floor before using them.
