Is every black, hairless spider a black widow?

No. There are several species of spiders that look like black widows. They're called false black widow spiders. If you are bitten by a false black widow, it is a lot like being bitten by a bee. It is painful, but it is rarely followed by serious medical symptoms.

How can I tell the difference between a black widow and other black spiders?

It can be a little tricky. Black widows don't make it easy. While you can tell that a spider is a black widow spider because of its jet black coloration and its lack of hair, it can be difficult to distinguish between false widows and dangerous widows. It can also be difficult to tell between a male and female black widow spider. This is an important distinction. Male widows are smaller in size and don't inject as much venom as the females. It is best to stay away from all widow spiders and reach out to a licensed professional for identification and control.

How big is a black widow?

It depends on the species. They can be ⅓ of an inch to as long as 1.5 inches. Males are half the size of females.

Do all black widows have a red hourglass?

No. A black widow spider does not always have a clearly recognizable hourglass-shaped red marking. But, if you see red on a black spider, that's all you need to recognize the spider as a dangerous widow. False black widow spiders do not have a red hourglass marking.

Can a bite from a black widow kill you?

This is probably the question we get the most. We're happy to say that the stories of deadly black widow bites are far more common than actual fatalities. It is rare for a person to die from a bite, even a bite from a female black widow. It is, however, very unpleasant and often leads to a hospital visitation. In fact, we recommend that you seek medical treatment immediately.

How bad is a black widow bite?

The symptoms of a black widow spider bite range in severity. You may experience localized pain, a burning sensation, redness and swelling around the bite wound, a headache, weakness, eyelid swelling, watering eyes, and sweating. These symptoms may progress to nausea, vomiting, chest pains, respiratory difficulty, and tremors.

How do I keep black widow spiders out?

You can keep these spiders out of your home like you would many other pests. Do a detailed inspection of your foundation wall and exterior. If you see gaps, cracks or holes, seal them. You can also reduce the risk of infestation by reducing bugs around your home. These are food for black widow spiders. The best way to do this is with residential pest control provided by a licensed pest professional.

How do I prevent black widow spider bites?

  • Wear work gloves when working in your yard.
  • Refrain from walking around outside in your bare feet.
  • Shake shoes before putting them on.
  • Be cautious when turning objects over in your yard.
  • Be cautious when getting boxes out of storage.
