It’s Hobo Spider Season in Utah!

Are you worried that you may have been bitten by a hobo spider? If you live in Utah, you’ve probably heard that hobo spiders are dangerous and aggressive—that one bite can cause serious skin lesions and nausea. However, recent research suggests that hobo spiders are not as dangerous as they seem.

Hobo spiders are common enough to be found all across the Wasatch Front. In Utah, male and female hobo spiders mature to adulthood from June to September and are actively seeking to mate. August and September are when most people notice hobo spiders because the females start laying eggs sometime around mid-September.

Along with Hobo Spiders, many spiders are more active this time of the year, including black widows.

Identifying Hobo SpidersHobo spider top down smaller

Hobo spiders are often misidentified as brown recluse spiders (a poisonous spider with a bite that can cause skin lesions). However, brown recluse spiders are native to the Midwest and Southern states, and they don’t normally travel this far west.

Hobo spiders have a long, rounded body with a dark striped pattern on the back and patternless yellow/brown legs. They struggle to climb walls and smooth surfaces, so hobo spiders usually hide in corners on the ground. These spiders create funnel-shaped webs that they rest in while they wait for their prey.

Are Hobo Spiders Dangerous?

Hobo spiders usually bite humans only if they feel threatened or trapped. Many people think hobo spider bites cause skin lesions and other serious side effects. However, scientists have never found sufficient evidence to prove this.

A few recent hobo spider bite research studies have concluded that hobo spiders are not dangerous to humans. In one case, a bite caused twitching, but in all other cases, hobo spider bites caused only mild redness and itchiness.

If a hobo spider bites you, over-the-counter anti-itch creams and damp, cool cloths may help relieve the itchiness.

Occasionally, spider bites may become infected, or people may experience an allergic reaction to a bite. In cases like these, people see the usual signs of an infection (skin discoloration, puss, tenderness, etc.) or an allergic reaction (a rash, excessively swollen skin around the area, etc.). If you experience symptoms like these, seek medical attention.

Hobo spiders like dark, cool corners that remain undisturbed. They hide outside in firewood, in messy corners of garages, and in cracks. Do the following to prevent hobo spiders from moving in:

  • Keep corners in your home and garage clean and clutter-free
  • Seal cracks around the base of your home and near entrances
  • Spray insecticide around the base of your home
  • Wear protective clothing to cover your skin while working in the garden or cleaning up cluttered areas in your home/garage
