Steps

Identifying a Brown Widow Spider

Observe the color of the spider. Brown widows will be brown, tan, and gray with a mottled or spotted pattern. Some may also have white or black markings on their backs.

Look for the hourglass marking. Like black widows, brown widows have a very distinctive hourglass marking on the underside of its abdomen. This marking, however, is yellowish to bright orange.

Take note of any dark bands on the legs. The front pair will be longer than the rest.

Check the size. The females will be 1 to 1 ½ inches (centimeters) long, including the legs. The males will be ½ to ¾ of an inch (centimeters) long.

Search for any round, spiky egg sacs. Brown widow spiders can look similar to certain species of black widow spiders, and their brown color can make them hard to distinguish from other spiders. Knowing what a brown widow's egg sac looks like can help you identify it with more certainty. Here are some things to look for: Size: ½ inch (centimeters) Color: Ivory, tan, or yellow Shape: Round and spiky Location: On the web

Look for cobwebs. Brown widow spider webs look different from the traditional lace-like spider web. Instead, they are three-dimensional (instead of flat) and cobwebby.

Know when to see a doctor. Sometimes, the body can have a far more severe reaction to a spider bite. If you experience any of the following symptoms, visit your doctor immediately: Trouble with breathing or keeping conscious Muscle cramps or tremors Sweating Nausea and vomiting Severe pain Infections at the bite site, such as rashes, pus, or ulcers

Take care of the bite by cleaning it and applying an ice pack. Clean the bite using soap and warm water; be sure to rinse it well. Elevate the bitten area, if possible, and place an ice pack over it; you can also use a cloth soaked in cold water. Washing the bite will help prevent infection while keeping it cool will keep the swelling down.

Take some over-the-counter medications. Spider bites can be itchy and uncomfortable, and brown widow bites are no exception. If you get bitten, consider taking some medication for it: Consider taking a pill, such as an acetaminophen, antihistamine, or ibuprofen. You can also use an anti-itch or anesthetic spray. Try to choose one that has benzocaine in it; this will help reduce the itching and pain. If the bite is red and won't stop itching, try an anti-itch cream, such as an hydrocortisone cream or a calamine cream.
