Are you seeing brown recluse spiders in Ohio? Here’s how to recognize them and stay safe
Seeing a spider in your home or garage is unsettling for sure. But if you see one with such a scary reputation, like the brown recluse, how do you know what to do next?
Here’s what Ohio folks need to know about how to spot the spider and what to do if you encounter one.
Brown recluse spiders are rare in OH but not impossible
The brown recluse spider (Loxosceles reclusa) does occur in Ohio but is uncommon and primarily limited to the southwestern part of the state, near the Indiana border. According to the Indiana and Ohio Brown Recluse Project at Indiana State University, their numbers sharply decline as you move north and east across Ohio, largely due to the state’s cold winters which limit their outdoor survival.
While brown recluse spiders thrive in warmer southern states, in Ohio they are mostly found indoors — in warm, dry, and secluded places such as basements, closets, attics, garages, and storage boxes. Occasionally, brown recluse spiders are transported inadvertently in furniture, boxes, and other household items, resulting in isolated populations outside their natural range.
It may not be a brown recluse, after all
Ohio State University notes that many suspected brown recluse bites in Ohio turn out to be caused by other issues like bacterial infections (including MRSA), diabetic ulcers, or other insect bites. Public fears and media attention sometimes lead to misdiagnoses without proper spider identification.
Dr. Susan C. Jones, an entomology expert at OSU , emphasizes the importance of confirming the spider’s identity before assuming a brown recluse bite, since improper treatment for other conditions can be dangerous.
How to identify a brown recluse
If you see a spider skittering across your floor and you suspect it might be a brown recluse, there are a few features you should look for.
Here’s what Ohio scientists say to look for:
Light to medium brown in color
A dark violin-shaped marking on the back, right where the legs attach to the body
About the size of a quarter in size
Brown recluse spiders have six eyes arranged in pairs (most spiders have eight eyes in two rows)
They don’t spin elaborate webs, but prefer hiding in secluded areas
Tips for staying safe
While encountering it’s smart to take precautions in outbuildings or crawl spaces.
Wildlife experts offer some advice:
Wear gloves when cleaning garages, attics, or sheds
Shake out shoes, clothing, and bedding that have not been unused for a while
Keep areas clutter-free and seal cracks around doors or windows
Store boxes off the floor and sealed tightly
Avoid leaving shoes or toys outdoors overnight
Treating a brown recluse bite
While encountering a brown recluse is unlikely, if do you get bitten, follow the following steps:
Wash the bite area with soap and water
Apply a cool compress
Seek medical attention, if the bite shows severe redness, pain, or forms an ulcer
The most important advice you can follow is not to panic. Since these kinds of spider bites are rare in Ohio and most spiders you find are beneficial pest controllers, it’s smart to stat informed from credible resources like OSU and the Ohio Department of Natural Resources.
