Here’s some help identifying our 8-legged little friends. Generally speaking, none of them will bite you, unless provoked or smooshed by toes, fingers, etc. suddenly pinning them somewhere.

I’m sure this doesn’t cover every arachnid out there, and I will add more as I learn of them. I know y’all are going to ask about the brown recluse. From everything I’ve read, they don’t live up here. Like any critter, it’s possible for them to hitch a ride in human stuff being transported from other areas, but I guess the little dudes don’t do so well in this environment.

American Grass Spider

Can bite

Grass spiders are fast and shy, and thus avoid contact with humans unless they feel threatened. Even though they are not poisonous, they are venomous like other spiders. Furthermore, their small fangs make it difficult to penetrate human skin, making the possibility of a spider bite low.


American Nursery Web Spider

Can bite

Nursery web spiders are not aggressive to humans, but the female guards her egg sac ferociously, so interfering or tampering with it could result in a bite. A nursery web spider bite is likely to be large and painful due to the size of this spider. However, it is not considered dangerous.


Black Widow

POISONOUS BITE

They have fangs and venomous glands sufficient to cause harm to humans. The female gender of the species is the most dangerous, compared to their male counterparts. Females have more prominent venomous glands, longer fangs and a body size that can reach up to 20-times larger than their male counterparts.


Camel Spider (Solifugae)

Can bite (no venom)

The Solifugae has neither venom glands nor any venom-delivery apparatus. Though they are not venomous, the powerful chelicerae of a large specimen may inflict a painful nip, but nothing medically significant.


Cat-faced Orbweaver

Can bite

Cat-faced spiders are totally harmless to humans. Although they have venom, they rarely attack people. Their venom is mostly mild


Cellar Spider

Won’t bite

Cellar Spiders are beneficial to have around because they have been known to hunt down and kill venomous spiders.


Daring Jumping Spider

Can bite

jumpers are shy spiders that retreat from humans when approached. If handled, they generally do not bite. These characteristics make them appear to have a great deal of curiosity and personality.


Desert Tarantula

Can bite

In general, the effects from tarantula bites are mild. A greater health risk is from contact with the spider’s hairs. Contact of the hairs with the skin causes lots of inflammation including pain, redness, itching, and swelling that can last for weeks.


Banded Garden Spider

Can bite

These spiders rarely bite humans in Nevada and are not aggressive. They may bite in self-defense if handled and bothered, but it’s unlikely that the bite would cause more discomfort than a bee sting.


Wolf Spider

Can bite

Wolf spiders will bite if provoked, but their venom is not dangerous to humans. Bite symptoms are minimal and may cause itching, swelling, and mild pain.
