Poisonous Spiders in Oklahoma
Generally speaking, almost all spiders are venomous (not poisonous). However, only very few species actually have the ability to cause any significant harm to people. Casualties from spider bites in the United States are extremely rare. In fact, around ten times as many people die from bee or wasp stings than from spider bites. In Oklahoma, there are two genera of medically significant spiders: Black widow spiders and the infamous brown recluse.
Appearance: Black widows are predominantly black spiders with a red hourglass shape on the underside of their abdomen. Their abdomen is round and shiny and their legs are long and slender. You can see images in the overview below. Black widows are often confused with the false black widow spider (Steatoda grossa).
Symptoms of a bite: A bite of a black widow can cause immediate flu-like symptoms as well as localized pain. Symptoms can include fever, nausea, dizziness and local swelling. If you suspect that you have been bitten by a black widow, seek medical attention.

Brown recluse spiders in Oklahoma
Brown recluse spiders occur throughout Oklahoma. Sightings west of Guymon in the panhandle are extremely rare, however. As the name suggests, brown recluse spiders are predominantly brown spiders. They can be identified by a darker brown violin-shape on their back and the fact that they have six eyes (most other spiders have eight eyes). Brown recluses are not large spiders and their bodies grow to a maximum of 3/4 in (20 mm). Their legs are long and slender.
The majority of alleged brown recluse sightings are actually other brown spiders in Oklahoma that are misidentified, like wolf spiders, nursery web spiders or others.
Symptoms of a bite: A bite of a brown recluse can cause severe skin damage. Symptoms usually show only a few days after a bite and can include redness or infections around the bite wound that can get worse over time. If you have been bitten by a brown recluse, seek medical attention immediately. If you have spider bite wound that gets infected or develops are red area around it, you should consult a medical professional as well.
The brown recluse, loxosceles reclusa, is one of the more dangerous spiders indigenous in the United States. While usually not life-threatening, a brown recluse bite might lead to severe skin damage.

What about hobo spiders or other venomous spiders in Oklahoma?
In the late 20th century, myths about the deadly and aggressive hobo spider made their rounds through newspapers and emails. The fact that hobo spiders (Eratigena agrestis) are potentially dangerous or especially aggressive has been rejected by scientists as there isn’t one single proven case of a hobo spider bite that caused any serious effects on a human. Furthermore, hobo spiders are exclusively found in the Pacific Northwest and do not occur in Oklahoma.
Other spiders that bite in Oklahoma and that can cause effects such as headaches and severe pain are yellow sac spiders (Cheiracanthium sp.). However, these spiders are not considered medically significant.

The largest spiders in Oklahoma are wolf spiders and tarantulas. Wolf spiders can reach a leg span of over 4 in (10 cm). Tarantulas can reach an even bigger body size than wolf spiders but have shorter legs – the largest tarantula found in Oklahoma is the Texas brown tarantula (Aphonopelma hentzi), aalso called Oklahoma tarantula, that can reach a legspan of up to four inches.
Other large and brown spiders in Oklahoma are grass spiders, fishing spiders, southern house spiders, huntsman spiders and nursery web spiders.
