Black widow venom causes fever, severe pain and stiffness, but these symptoms may not appear for a few hours. A brown recluse bite has similar symptoms, but is most distinguished by a large, fluid-filled blister. When the blister drains, it leaves the victim with a gaping ulcer. These bites have been known to cause death in very rare cases, but are otherwise easily treated. Contrary to popular belief, most spider bites are harmless.

Use these tips from Mayo Clinic to minimize spider bite discomfort:

Identify the Spider
Knowing what type of spider bit you will help you properly treat the bite. Some spider bites, such as those of a recluse, are more serious than others and may require immediate medical attention.

Clean the Wound
Infection is one of the most common complications of a spider bite, and can be worse than the bite itself. Use soap and water or a cleansing solution to disinfect the area. Applying antibiotic ointment will provide further protection against infections.

Keep It Cool
Applying a cold compress can help ease some of the discomfort of a bite. It will reduce swelling, as well as soothe itchiness or burning. A cold, wet cloth or bag of ice will also do.

Isolate the Area
In the event of a black widow or brown recluse bite, cut off circulation from the affected area by cinching with a belt or tie. This will help stop the spread of venom until medical assistance arrives.

Stay Alert
On rare occasions, a person may experience a severe allergic reaction to spider bites known as anaphylactic shock. Shock can cause the throat and nasal passageways to close, making it difficult to breathe. Nausea, rapid heartbeat, dizziness and low blood pressure are other symptoms. Call 911 as soon as possible. In most cases, doctors will administer an injection of epinephrine to stop the reaction.

While bites and cobwebs are at the top of our list of gripes against spiders, they do play an important role in human wellbeing. In addition to keeping disease-carrying insects at bay, the common house spider has been known to eat more dangerous varieties.

Spider venom is also used to produce medicine for treating stroke. Keep that in mind the next time a spider gives you a case of the creepy crawlies and save a spider!
