Can Spiders Cause Hives?

Spiders, like most insects, aren’t dangerous. Most bites are harmless, though they can cause an allergic reaction. Symptoms may include swelling, itchiness, redness, pain, and lightheadedness. If symptoms become severe, you should seek medical attention.

In many cases, the bitten area will be itchy. You may also notice a red welt around the bite. The welt will begin to fade within a few days. However, some people will experience a more serious allergic reaction, such as a hive.

Hives are a type of allergic reaction that may be caused by a variety of different insects, spiders, and other stinging creatures. They are caused by an inappropriate release of histamine.

A hive will usually go away within 24 hours, but can last for several weeks. Some hives are itchy and raised, while others are more localized. People with chronic hives should be evaluated by a doctor to determine the underlying cause.

While most spiders are harmless, some are venomous. They can cause anaphylaxis, which is a severe, whole-body reaction. Anaphylaxis is often sudden and can result in nausea, a rash, and even loss of consciousness.

There are a number of ways to prevent spiders from biting you. For example, you can cover your skin with insect repellent. Also, keep your skin clean. It’s important to get prompt medical care if you have any of these symptoms after being bitten.

Depending on the severity of the reaction, you might require antivenom. Antivenins are available for most venomous spider bites.
