Poisonous Spiders of South Carolina
The Dreaded Black Widow Spider
In case you don't know, almost all spiders are capable of producing venomous bites. But in South Carolina, there are really only two species of spider that you have to worry about. They are the Black Widow Spider and the Brown Recluse Spider. In the United States, about six deaths a year are caused by spider bites. On average, bees and wasps cause 12 deaths a year, while snakes cause about 10 deaths a year.
Now, that shouldn't let you take spider bites lightly, because spider bites can cause serious injury even if they don't kill you. Black Widow Spiders have more potent venom than other spiders. Their venom is a neurotoxin, and it can cause swelling and severe skin damage if not treated. If you think you have been bitten by a Black Widow Spider, go to your nearest hospital emergency room or doctor. If you can do it safely, catch the spider in a jar with a tight-fitting lid and take it with you when you seek medical treatment.
Spiders like clutter and dark places. And spiders especially like to nest in cardboard boxes, especially in attics, closets and under beds. They also are known to hide in wood piles and in rural mail boxes. If you're working with firewood that has been stacked a while, wear long sleeves and gloves. In South Carolina, especially in the low country, these spiders make their homes in outdoor buildings, rock walls and other dark places.
The cleaner you keep things, the less problems you will have with spiders. If you have to store things, use plastic boxes with tight-fitting lids, and be careful with boxes and their contents that have been stored for a while. Be especially careful if you can see spider webs. If you see spider webs, wear gloves and be prepared to use deadly force if you see a Black Widow Spider. You can purchase spider spray and spider traps to use under beds, in attics and in out buildings.
You should be aware that both Black Widow Spiders and Brown Recluse Spiders like to live in stored cardboard boxes. People often receive spider bites when they crush or mash a spider. So if you think a spider might be present use caution.
If you have a rural mail box check in it and under it regularly, because Black Widow Spiders really do like to make their home in mail boxes. If you see a spider in your mail box, spray it with a commercial pesticide made for spiders. Afterwards, you can wash your mail box out with warm soapy water, which incidentally also gets rid of spiders.

Things You Can Do to Prevent Spider Bites
Do you know that the Black Widow Spider's bite is 10 times more deadly than a rattlesnake bite. So it's important that you and your other family members can identify a Black Widow Spider and a Brown Recluse Spider. There are several preventive measures you can take to prevent these spiders from biting you.
- Carefully take down all the curtains in your house and wash them in hot soapy water. If you see spider webs behind your curtains, clean up everything with a strong insecticide soap. If you suspect spiders are about, wear a longsleeve shirt and gloves while you do this.
- Set your bed out away from the wall and away from curtains. Spray under your bed and on your washed curtains with a strong pennyroyal solution. This prevents spiders better than anything.
- If you know or suspect there are brown recluse or black widow spiders in your house, remove all bed skirts. Store any shoes you're not wearing in a plastic container with a lid.
- Keep the floors of closets and under your bed very clean. Don't use cardboard boxes and don't let clutter build up. Prevention is the best way to keep spiders away. If you suspect you have spiders about, buy box spider traps and set them out for a few days in a dark area. If you find Vrown Recluse or Black Widow Spiders in your spider traps call a professional pest control company to deal with your spider problem.
- Don't put on clothing, socks or shoes on without carefully shaking them out to see if spiders are hiding in them. If spiders are about, never wear clothing that has been lying on the floor. What often happens is that a spider will hide inside an item of clothing and then when the person puts the shirt or pants on they will receive a bite. Be sure to shake your shoes out before you put them on.
- If you have a bad spider problem, don't store anything under your bed. Keep it perfectly clean, and spray oil of pennyroyal under your bed so no spiders will set up homes there. Use plastic boxes with tight-fitting lids instead of cardboard boxes. For some reason, spiders seem to love cardboard boxes. You should always try to have as little clutter as possible, so you won't have as many spiders around.
Have you seen what you know was a Brown Recluse Spider in or near your home?
Brown Recluse Spiders in South Carolina
It is believed that the Brown Recluse Spider is expanding its original range and its now found in most of South Carolina. You can look at the photos above to see if the spider you're seeing is indeed a Brown Recluse Spider. Never assume that because you live outside the normal range of the spider that one of them or more can't show up in your home. If you live in much of the old American South, its likely that the spider may have expanded into your area.
At one point in time the spider was not found in Florida, but the spider has recently been found in large numbers in houses and buildings in the state. It appears that the Brown Recluse Spider has become yet another invasive species that has invaded Florida. I have found the spider in the attic and basement of a house I own in St. Augustine, Florida, so it's likely the spider is quickly expanding its original range.
After much research, I now believe that the Brown Recluse Spider has established itself in every county of South Carolina.
The Brown Recluse Spider is rarely aggressive, and most bites occur when someone mashes a spider or crushes it accidentally. If you know the spider occurs in your area be, sure to shake your shoes out before you put them on. If you move items like firewood, wear longsleeves and gloves.
If you live where these spiders occur like South Carolina, don't store your belongings in cardboard boxes because these spiders love to make nests in them. Use plastic boxes with lids for storing items in, and put pennyroyal in each box to ensure no spiders make their home there. Pennyroyal is a member of the mint family, and it is also known as squaw mint, pudding grass and mosquito plant. You can also purchase pennyroyal oil and put a tablespoon in a pint of water and spray your storage containers to keep away not only Brown Recluse Spiders but all spiders.
The Brown Recluse Spider may bite you, and you may not even feel it at first. Skin necrosis occurs in 37 percent of Brown Recluse Spider Bite. When it does, it can result in the loss of a finger if the bite occurred there or even the entire limb. The bite can cause a necrotizing ulcer that destroys soft tissue and can take months to heal.
A Brown Recluse Spider bite can become itchy and painful within 8 to 12 hours of the spider bite. If you have a place like this on you that you suspect may be a Brown Recluse Spider bite, seek medical attention at once and tell the medical practitioner you suspect you may have been bitten by a Brown Recluse Spider.
The Brown Recluse Spider was first confirmed in South Carolina in 1976 at Goose Creek South Carolina. Since then, Brown Recluse Spiders have been found at the University Of Clemson and in Liberty South Carolina where 14 spiders of the species were found in one house.
The Brown Recluse Spider is a rather small spider that is usually about 1/8th of an inch long. They are almost never bigger than a U.S. quarter. They can be light brown to yellow in color. This spider has three pairs of eyes, and that is a easy way to identify it. The distinct violin shape on its back is not a reliable way to identify it, because you will see other brown spiders with these markings. Brown Recluse Spiders live for a rather long life span. It is not at all unusual for the spiders to live two years or longer.
Effective Spider Control
You can keep away spiders by keeping the area super clean and by keeping away any insect prey. If there are a lot of insects around, then you're going to have a healthy spider population around also.
- Use chemical control. Be sure any pesticide you use contains pyrethrins, which kill and control spiders. These chemicals assure a quick kill of any exposed spiders. If you have a healthy population of spiders, call in a professional pest control company. Especially if you're seeing large numbers of Brown Recluse Spiders or Black Widow Spiders.
- Keep all areas very clean, especially cabinets, attics, closets, storage areas and under beds. Try to use plastic boxes with lids for storage and never cardboard boxes.
- Wash down all outside areas with a strong insecticidal soap that contains pyrethrins. Keep bushes and trees cut back away from your house. Keep bushes trimmed and don't let them touch your house.
- Discourage spiders by knocking down or washing down their webs, nests, egg sacs and the spiders themselves. Don't let them get established and you won't have spiders. If you're seeing spider webs, then you need to step up your spider eradication methods.
If you end up with a red swelling bite that itches and is painful, apply ice to the bite area and seek medical attention at once. Don't wait to see if it's going to get better. Seek medical help immediately.
