In Utah, male and female Hobo Spiders mature to adulthood from June to September and are actively seeking to mate. This is the time of year when Hobo’s are most frequently encountered. The females will start laying eggs sometime around mid September.
Along with Hobo Spiders, many spiders are more active at this time of the year including Black Widows.
Hobo spiders are dangerous and a sighting should be taken seriously. They are common enough to be found all across the Wasatch Front.
