Wolf Spider

Tennessee is a popular state for many species of spiders. Many of us have a fear of spiders and some of us have developed arachnophobia (a pathological fear or loathing of spiders). Many species of spiders found in Tennessee are harmless. Wolf spiders as pictured above, rarely are aggressive. Many species can actually be beneficial to humans by preying upon nuisance insects such as flies and crickets. The big black spiders we often fear at Halloween or in nightmares are likely not harmful, maybe a garden variety. If a big Black House Spider decides to bite you. Find out about the poisonous spiders of Tennessee and how to identify them.

Spiders at Nashville Zoo

The Nashville Zoo has spiders on display at their Unseen New World indoor exhibit. The zoo houses tarantulas and some native Tennessee poisonous spiders. The two deadliest spiders—the brown recluse and black widow—are both deceased versions at which you can look closely through a magnifying glass to learn how to identify. In fact, the only two Tennessee spiders considered poisonous are the black widow and the brown recluse spiders.

Tennessee Spider Sightings by County

According to the Tennessee Poison Control Center, brown recluses and black widow spiders reside in every single county in the state. Some species of wolf spiders are also native to Tennessee. Yes, they are hairy and they bite, but their venom doesn’t kill or have much of an effect on humans. A wolf spider’s bite does cause serious pain, so the Priority Pest control team recommends you stay far away from these arachnids.

About Brown Recluse Spiders—Behavior and Bites

Brown Recluse Spider
Brown Recluse Spider

Just as you would guess from its name, the brown recluse is not an aggressive spider. It rarely bites but then it does, a sore wound results that is itchy and takes time to heal. It is medium in size with its legs extending approximately an inch or two. The coloring varies from a light yellow-brown to a dark brown or reddish brown. Recluses have three sets of eyes; most spiders have four pairs of eyes. The best way to tell if a spider is a brown recluse is to view the top of the body right above the legs and look for a violin-shaped mark.

It is very possible to reside in a home that is infested with brown recluses and never get bitten. The majority of brown recluse bites happen when the spider is caught against bare skin. For instance, bites have occurred when people roll over on a brown recluse in bed or put on a shoe with a spider inside. Because brown recluses hide, they can quickly multiply and before you know it your home is infested. At the first spotting of a brown recluse call a pest control professional.

What to Do When Bitten by a Brown Recluse

If you or a family member has been bitten by a brown recluse, be sure to seek medical attention. Many victims don’t realize they have been bitten. Unless you see the spider on you, you may not be aware of the bite. It may sting and may not. They are usually pain free. The initial bite is generally not painful at all, later the bitten area often becomes irritated and red. Some people have a minimal reaction to the bite and others suffer wounds and ulcers. Most brown recluse spider bites heal within a few weeks following the bite, and do not have serious complications. Others are less fortunate. They may develop a lesion, appearing as a dry area that caves in with irregular edges and outside redness. As the spider’s venom continues to destroy tissue, the resulting wound may grow larger and linger for months.

About Black Widow Spiders

Black Widow Removal Tennessee
Black Widow Spider

Black widow spiders like closed, dark places such as barns, garages, basements, hollow stumps, or thick vegetation. These spiders are common in Tennessee, yet reported incidents of bites are few. The two species prevalent in the state include the northern and southern black widow. This spider has a shiny appearance. The body color may be a dark black to a dark or reddish brown. To tell if a spider is a black widow, look for two red triangles shaped in an hourglass on the belly of the spider. This indicates it is a female black widow. Female black widows are not aggressive and only bite when their webs are disturbed or in self-defense. Their bites have rarely resulted in human deaths, yet their venom is powerful. The male spiders have a distinctive pattern on the spider’s abdomen that is a row of red dots and white or yellow lines. The male black widow is harmless.

*Note: There is also a brown widow spider that has been spotted in Tennessee, likely migrating here from South Africa. The brown widow’s venom is twice as strong as the black widow. The good news is that the brown widow shoots out much less venom.

Responding to a Black Widow Spider Bite

If you or a family member has been bitten by a black widow, be sure to seek medical attention. The female black widow has a very strong venom. The bite often feels like a pin prick initially. You may not notice you have been bitten. Within a few minutes the victim will feel pain that extends to other parts of the body, including arms, legs, chest, etc. Effects include chills, difficulty breathing, sweating, nausea, and abdominal pain. The victim usually feels fine after a few days. It is estimated that 5% of black widow bites are fatal.
