Missouri is home to many different types of spiders of all different sizes, shapes, and colors. Some of them can even be very poisonous and could require medical attention after a bite! Unlike insects, spiders have eight legs and are in the arachnid family along with mites and ticks. Spiders can live in almost any habitat. Below are some of the most common spiders in our area.


Black Widow

Black Widow

The female black widow is easily identifiable with her black body and reddish hourglass shape on her abdomen. Males are usually lighter in color with a median row of red spots with white lines on the sides. Immature black widows are usually orange and white, turning black as they mature, with 1 or 2 reddish markings on the abdomen. Outside, black widows are commonly found in protected areas under firewood, decks, in hollow stumps, rodent burrows, etc. They are also frequently found inside barns, sheds, henhouses, meter boxes, barrels, etc. While indoors, black widows can be found in rarely used areas of basements, crawlspaces, and garages. It is a very poisonous spider, and if bitten, seek medical attention immediately. The venom is known as a neurotoxin and should be treated with an antitoxin.


Brown Recluse Spider

Brown Recluse Spider The brown recluse is light tan to dark brown in color with a violin or fiddle shaped dark brown mark starting at the front of the spider, with the neck of the violin pointing towards the rear. Their name comes from their reclusive habits. They prefer to live in undisturbed, seldom used areas such as boxes, underneath tables and chairs, along baseboards, in closets, attics, crawlspaces, and basements. Outside, they live around rocks, logs, woodpiles, in utility boxes, exterior rodent bait stations and debris. If disturbed, the spider will usually try to run for cover instead of biting. Bites mostly occurs when putting on rarely used clothing and shoes, cleaning out closets or storage areas, and rolling over on one while in bed. Their bite is not usually felt immediately but rather felt within 6–8 hours of being bitten. An ulcer will usually form where the bite was and can result in severe scarring. There is no available antitoxin for bite victims.
