Spider bites can be itchy and painful. Some spider bites are quite dangerous, but most are easily treatable. While it is helpful to recognize spider bites, you should still seek medical attention as confusion is also common. Even if medical personnel confirm that the bite is not dangerous, you should still monitor at home and watch for signs of a bad reaction.

Observe the body of the Sydney funnel web spider. This very aggressive spider, with a glossy body resembling a tarantula, usually lives in the dark and damp areas of southeastern Australia. You need immediate medical attention if you are bitten by a Sydney funnel web spider, as the symptoms of poisoning develop very quickly.

  • The initial bite will be intensely painful. Although there is not much inflammation or blistering, the victim will sweat, face convulsions, and may have a stinging sensation around the mouth. This case needs to go to the hospital to be treated with antivenom as soon as possible.

Recognize the large and hairy body of the Brazilian wandering spider. The Brazilian wandering spider is a large, aggressive nocturnal spider that lives in the southern United States. They have a hairy, brown body, about 5 cm long, and have black markings on their abdomen. This spider does not web, but roams at night and often lives in banana bushes or hides in dark areas. [1] X Research Source

  • The bite of this spider causes local swelling and pain radiating to the upper body, which can be accompanied by symptoms such as nausea, vomiting, increased blood pressure, shortness of breath, and erections in men. Antivenom is available to relieve symptoms, and death is rare.

Notice the blistering bite that is filled with brown recluse fluid. Brown recluse spiders come in a variety of shades of brown, but they all have a violin-shaped spot on their backs and long, slender legs. This spider’s bite initially stings, then turns to intense pain over the next 8 hours. A fluid-filled blister will progress to a continuously spreading ulcer, and red-green streaks radiating around the bite signal permanent tissue damage. [2] X Research Source

  • Other symptoms include fever, rash, and nausea.
  • Although the bite of the brown recluse spider is terrifying, it has not caused any deaths in the US. There is currently no antivenom for this spider, but there are treatments for lesions with surgery and antibiotics.

Notice the red hourglass-shaped spot of the black widow. This is a large, shiny black spider with a red hourglass-shaped spot on its abdomen. They are present throughout North America. The bite of a black widow spider causes a stinging, reddening and swelling sensation, but the victim will begin to experience severe pain and stiffness within 30 minutes to several hours. [2] X Research Source

  • Other possible symptoms are severe abdominal pain, nausea, fever, or chills. Black widow spider bites are not usually fatal to healthy adults because antivenom is available, but the victim can lose a limb if left untreated.
  • Note that the black widow and brown recluse are the only two dangerous venomous spiders in the United States. They all live in warm climates and prefer dry, dark places like closets or woodpile piles.

Notice the red stripe on the redback spider’s back. Closely related to the black widow spider, the redback spider lives throughout Australia, especially in urban areas. Only female spiders are dangerous. They have a pea-sized, black (sometimes brownish) body with a red stripe on the back and a red-orange hourglass shape below the belly. [3] X Research Sources

  • The person bitten by a redback spider will sweat, vomit, nausea, muscle weakness, and pain, sometimes very intense.
  • Thanks to the intervention of antivenom, no deaths from redback spider bites have been recorded.

Seek emergency medical attention. Get medical attention right away, even if you think the bite is not serious. Anyway, identifying a spider bite is easy to confuse.

  • Getting an antihistamine shot as soon as possible is also a good idea, even if you can’t determine which spider has bitten. Although antivenom is usually available in an ambulance, it does take some time to select and inject.

Apply an ice pack. This step will help slow the spread of the venom and reduce swelling.

  • Apply warm compresses if you believe you have been bitten by a Brazilian wandering spider. This will reduce the blood pressure at the wound.

Reduces the propagation speed of the venom. If the bite is on an arm or leg, elevate that limb and apply a tight bandage over the bite. You should also limit your movements as much as possible to slow down the venom’s movement.

  • Be careful when dressing so as not to block blood circulation.
  • Do not bandage the area of the bite if you believe you have been bitten by a redback spider. The venom of the redback spider spreads slowly, so this will not help and will only make you more painful. [4] X Research Sources

Take the spider to a medical facility, if possible. Even if the spider has been crushed, you should still try to keep it and take it to the hospital. A blood test can help determine which spider bite belongs to, but if you have a sample to bring, the process will be faster.

  • You can preserve the spider with rubbing alcohol.

Wash the bite with cool soapy water. Even if you believe the bite isn’t dangerous, you should still see a medical professional to get it checked out. If they determine that the bite is not dangerous, begin treatment by washing the wound with soapy water to help prevent infection. [5] X Trusted Source Mayo Clinic Go to Source

Monitor for the next 24 hours to make sure symptoms don’t get worse. Within a few days, the bite should be less painful and swollen. If symptoms do not improve, call a poison control center or see a doctor.

  • If the bite is only the size of a dime, you can monitor it at home. However, if the bite spreads with red streaks and swelling around the wound, seek medical attention promptly.

    Know when to see a doctor. In some cases, the bite of a non-venomous spider can cause an allergic reaction. Call 911 immediately if the person bitten by a spider has the following symptoms:

    • Shortness of breath
    • Nausea
    • Muscle spasms
    • There are stripes radiating around the bite
    • Throat constriction makes it difficult to swallow
    • Sweaty clothes
    • Feeling dizzy
  • Advice

    • If an unwanted spider clings to your skin, knock it out – if you hit the spider, its teeth will dig into your skin.
    • Clean the house regularly – most spiders prefer dark and quiet environments.
    • Shake clothes and shoes left on the floor or in a closet before wearing or putting them on.
    • Wear gloves and tuck the hem of your pants into your socks when working in the basement, outdoors, or anywhere spiders are common.
    • Move the bed away from corners and walls to prevent spiders from hiding in the sheets.
    • Isolate your home properly to reduce the risk of spiders entering your home.
    • Insect repellents containing DEET can help repel spiders.
    • Notify an adult immediately in case of spider venom.
    • Never poke a spider bite. It can break off and become infected.
