Hobo Spider

The Hobo Spider (Tegenaria agrestis.) has spun below the radar for many years. Despite their increasing range and population, public awareness of these spiders has been surprisingly low, primarily because the Brown Recluse Spider has been inaccurately blamed for the insidious effects that people receive from Hobo spider bites.

How to Identify a Hobo Spider

Hobo Spiders are brown and measure roughly 12 to 18 mm in length. Their legs show no distinct rings and have short hairs. Their abdomens have several chevron shaped markings. Males are distinctively different from females in that they have two large palps that look like boxing gloves. These palps are often mistaken for fangs or venom sacs, but they are in fact the male genitalia. The females also have these palps, but the ends are not ‘swollen’ as they are on the males. Females tend to have a larger abdomen when compared to males.

Hobo Spider Characteristics

The hobo spider creates a non-sticky (in spider standards) trip web that doesn’t permanently stick insects to the web. Instead, once the prey trips on the web the hobo spider attacks the prey before it can get away. This along with its poor eye site explains why they are noticeably more aggressive to humans then other spiders. They have to attack to eat otherwise it would die of starvation.

The hobo spider is known to be a fairly aggressive spider in its nature. When a hobo spider is tending to their eggsacs they tend to become even more aggressive and at that point they will attack. A hobo spider will usually bite a human due to getting trapped in clothing, in bed sheets, and being trapped next to the skin. The initial bite by the hobo spider usually is not painful, but in about thirty minutes a hard area will appear. Within 15 to 35 hours the sore will blister. The blister will break in around 24 hours, and the wound left behind generally will heal very slowly.

The Hobo spiders are not good climbers, and are usually found at ground or basement level. They sometimes climb up to a level of about four feet if the surface of the wall, etc. is sufficiently porous however they are not able to climb smoothe surfaces. Hobo spiders found in wash basins and bathtubs arrived there by falling down the slick porcelain surface; they did not come up through the drain.

High Risk Areas

The webs they make are funnel shaped and are often attached to an object in the yard, by the foundation, between planters, or anything that remains stationary near the ground level. It also makes webs under the siding of homes and attaching to plants or weeds.You may also find Hobo spiders in the following areas:
