On the other hand, brown recluse venom acts more locally, typically causing severe issues to the skin at the site of the bite. If you have severe symptoms following a black widow bite, your doctor will administer an antivenin intravenously. In the event of severe swelling, lesions or headaches, victims should immediately seek medical attention. If possible, take the spider along for proper identification. Knowing the signs and symptoms of a venomous spider bite can help you make an informed choice as to whether emergency medical care is needed or not. Bites from black widows or brown recluses are most dangerous to children (because of their small size) and people age 60 and older (who may be weaker or in poor health).

But if pain spreads beyond the site of the bite, or if the swelling, inflammation, or redness are getting worse even a day or two after the bite occurred, get medical attention. You may have a secondary infection — something caused by bacteria getting into the bite — or you may have been bitten by a widow or recluse, Day says. So the first thing every spider expert in America would like people to know about spider bites is that they’re uncommon and often misdiagnosed. That said, some spiders do bite people, and the result can be ugly. “Spider bites are really rare,” says Jonathan Day, PhD, a professor emeritus of medical entomology at the University of Florida.
Symptoms of Spider Bites
If you’re bitten by a black widow or brown recluse spider, don’t panic. “The vast majority of people do not have a significant reaction,” Dr. Bazzoli says. “Most of us, even when bitten by a black widow or brown recluse, don’t have any issues and don’t go to the hospital.” However, there are warning signs to watch out for after a bite. Wolf spider bites are usually harmless unless you are allergic to the venom, and most people are not. The bites are about as bad as a bee sting, causing redness and pain that should go away within 24 hours.

Brown Spiders
Squeezing a spider bite will not help reduce the risk of symptoms but may spread the venom or any infection further. Instead, wash the area with soap and water and keep it raised, if possible. Apply a damp cloth to reduce swelling, and seek medical attention as soon as possible. Brown widow spiders measure 0.47” – 0.6” (12 – 16 mm) long, making them slightly smaller than black widows.

While some spiders can be dangerous, most are actually beneficial and will help with other types of insect and pest control. Maintaining a pest-free home will lower the odds of getting bit inside your house. If you are experiencing mild symptoms or skin irritation following a spider bite, many at-home treatments may bring you relief. Sac spiders vary drastically in coloring and are sometimes confused with other spiders due to shades ranging from yellow to brown to green. It's a good idea to keep your distance from these spiders, as their venom contains cytotoxin and has been shown to be toxic to humans.
Treatment for Venomous Bites
Like all widow spiders, the brown widow has long, extended legs that are tan with dark brown bands. Once it is determined that your bite requires treatment, the healthcare provider will discuss a plan with you. Treatment for spider bites typically involves addressing the symptoms as they occur.

They may cause trouble breathing, a severe headache and painful muscle cramps that require immediate medical care. "The two types of venomous spiders that are really of medical concern are black widow spiders and brown recluse spiders," Gangloff-Kaufmann explains. A bull’s eye caused by a spider will happen immediately, whereas one from a tick can take anywhere from one to four weeks to appear. According to the CDC, common symptoms of spider bites include, but are not limited to, itching and rash, pain and aching, perspiration, elevated blood pressure, and nausea. If you suspect a venomous spider has bitten you, seek medical attention and do your best to identify the spider. “This is one of the few species of spider that can be dangerous to people,” says Potzler.

We will help you find the right treatment plan for your home. Fill a baggie with ice (or use an ice pack) and apply it to the bite — 15 minutes on, and then 15 minutes off.

Medical treatment for a spider bite depends on your symptoms and the type of spider bite. Mild symptoms that linger could require over-the-counter medications. Symptoms that are moderate or severe may require prescription medication or supervised care.
Severe spider bite symptoms occur as a result of the venom that the spider injects. Symptom severity depends on the type of spider, the amount of venom injected and how sensitive your body is to the venom. If you’ve been bitten by a spider, you may see a set of tiny fang marks where the spider broke your skin. In addition, you may notice mild swelling and redness or skin discoloration. Because of its large jaws, a camel spider can leave a significant wound in human skin.
If you have more than one bite on different parts of your body, or if several people in your house were also bitten, a spider is probably not to blame. In this case, your doctor will examine you to rule out other causes, like infection or vasculitis (a condition that causes blood vessels to swell). If you’re bitten by a venomous spider and go into shock or are having trouble breathing, call 911 or your local emergency services immediately. Some spider venom is toxic to people, however, and can definitely be dangerous. In the United States, recluse and widow spiders pose the greatest threat. Pain relievers may be needed to calm pain from spider bites.
Intravenous administration of benzodiazepines or cyclobenzaprine may be used to treat the muscle cramps and pain caused by black widow venom, according to the journal U.S. Opioids may also be used in the short term because long-term use can increase the risk of dependence. Keep the area clean while it heals to reduce the chance of infection. These symptoms may be signs of anaphylaxis, where your entire body reacts to the allergen. This is a medical emergency and needs immediate treatment.
