ARE UTAH CRAB SPIDERS DANGEROUS?
Some species of crab spider can grow quite large and are capable of inflicting painful bites on humans. The Utah crab spider is not one of these, however. While it may bite a human if provoked, it’s unlikely that it will even be able to break through the skin. If it does, the small amount of venom released will not pose any health risks.
- Female hobo spiders can have a body length of up to 16.5mm or 0.65 inches, with males being a little smaller.
- Hobo spiders have brown bodies with darker or lighter brown legs.
- While they generally have hairy-looking legs, some hobo spiders have smoother legs.

UTAH CRAB SPIDER CONTROL AND TREATMENT IN UTAH COUNTY AND SALT LAKE COUNTY
Bark crab spiders prefer to be outdoors in vegetation and on trees so it’s not that likely that you’ll find them infesting your home. If you do see them inside, however, try and trap them in a small container and release them back outside. Crab spiders reproduce quickly so by putting them back into their natural habitat, you can stop an infestation before it starts.
Pest control companies like H2 will not normally advise total eradication of Utah crab spiders from an outdoor space because a) it’s not possible to guarantee and b), spiders can be very beneficial to your yard. If you do want to reduce the number of Utah crab spiders in your yard, however, there are a few steps you can take:
- Utah crab spiders like plants that produce pollen, so reducing the number of this type of plant in your yard will also reduce the number of crab spiders.
- Maintain a neat lawn, especially near your home.
- Utah crab spiders prefer to live under loose bark and mainly on ground level. Getting rid of piles of grass clippings and other areas of plant debris will provide less of an ideal environment for these small spiders.
It’s not likely to find an infestation of Utah crab spiders in your home, but if they have invaded, contact a professional pest control company like H2 for effective pest control treatments. We operate throughout Salt Lake and Utah Counties and can provide personalized pest control plans for each client.
