What Is a Hobo Spider? | Identification, Habitat, and Behavior

Written by Thomas Matthews

Hobo spiders are generally considered some of the creepiest spiders out there. That’s because they like to hide in small, dark crevices where they lay their eggs in funnel-shaped webs, making some areas of peoples’ homes the ideal spot for these spiders. 

What is a Hobo spider and is it venomous? A Hobo spider is a small, fast funnel-web spider that stays close to the ground. They were previously thought to be very venomous, that is why it is important to learn more about the severity of their poison and how to get rid of them.

In this article, we’ll tell you everything you need to know about hobo spiders and how to get rid of them. We’ll also show you some of the go-to ways for eliminating these spiders from homes and outdoor areas so you won’t have to worry about them invading your private spaces ever again. 

Hobo Spider Identification, Behavior and Control

Hobo Spider Identification, Behavior and Control (1)

The hobo spider, Eratigena agrestis, is a small brown spider with long legs and a flat, circular body. It spins funnel-shaped webs. In the USA, it lives in the pacific northwest. 

Did you know that hobo spiders are called “hoboes”? This is because they travel from place to place on ships, trains, and cars.

They are initially from Europe, but they have spread to other regions with similar climates where they eat other spiders and take over the population.

Hobo spiders are notoriously hard to identify since there are so many other spiders that look very similar. One of the only ways to positively identify hobo spiders is using a microscope, and not many people want to get that close to one of these spiders.

What Do Baby Hobo Spiders Look Like?

Baby hobo spiders are often misidentified as house spiders since hobo spiders look much like other common arachnids. They are dark brown with long legs, and they scoot across the ground at high speeds. 

How Big Can Hobo Spiders Get?

How Big Can Hobo Spiders Get

According to experts at Utah State University, female hobo spiders are between 9.5 and 16.5 mm (3/8-5/8 in) long, and male hobo spiders are between 7 and 13.5 mm (9/32-9/16 in). Hobo spiders have a leg span between 2 and 3 inches (5 – 7 cm). 

How Many Eyes Do Hobo Spiders Have?

Hobo spiders have eight eyes arranged in two separate rows of four. But though they have eight eyes, hobo spiders have poor vision and can only see objects a few feet (75 cm) away.

This sometimes causes them to scurry towards people who think the hobo spider attacks them when the spider is not even aware of their presence.

Types of Hobo Spiders

There is only one type of hobo spider. Its scientific name is Eratigena agrestis, but it used to belong to the Tegenaria family. The word agrestis means “of the field” in Latin since these spiders often live in shrubs, dense grasses, bushy trees, and underneath rocks and logs. 

Where Do Hobo Spiders Live?

Where Do Hobo Spiders Live

In the USA, hobo spiders live in the Pacific Northwest. Generally, you can find them in British Columbia, Washington, Oregon, Colorado, Wyoming, Utah, northern Idaho, and Montana.

How Long Do Hobo Spiders Live?

Generally, hobo spiders live for around one year, but they can live for three years in warmer climates. Still, male hobo spiders die immediately after mating, so they never live as long as females. 

Do Hobo Spiders Make Nests?

Hobo spiders make nests out of their silky threads. They usually lay 50-100 eggs in each clutch which they spin a thick, white web over and attach to the undersides of leaves, logs, or stones. They lay their eggs in these webs.

The female lays her eggs in several white to cream-colored sacs which hang from the web.

Can Hobo Spiders Climb?

Hobo spiders can climb up carpeted or rough surfaces but with some difficulty since they are not good climbers. A hobo climber can climb up to a height of about four feet (1.2 m) if a surface is sufficiently rough or porous to let it get a grip. 

Can Hobo Spiders Jump?

Hobo spiders can jump, but not very well. According to arachnologists at Utah State University, they are swift, though, and they travel 0.45 meters (17 inches) per second on average. 

What Do Hobo Spiders Eat?

Hobo spiders eat flies, other spiders, crickets, and various insects that they can catch in their webs. Anything small enough to get entangled in a hobo spider’s funnel-shaped web will likely end up on the hobo spider’s menu.

How Dangerous Are Hobo Spiders?

No one knows exactly how dangerous hobo spiders are. Some people believe that they may cause necrosis or the death of tissues at the site of a bite. However, many scientists and scholars still debate whether hobo spiders are venomous since they rarely inject venom into human beings. 

Many people believe that hobo spider bites cause necrosis, or decaying flesh, in human beings. However, this fact has never been confirmed by health professionals or arachnologists. 

So, no one knows how poisonous hobo spiders are, but we know some things about their levels of aggression and what happens if they inject venom into a human. 

Are Hobo Spiders Aggressive?

Hobo spiders are often referred to by the common name “aggressive house spider,” but they are not aggressive. Hobo spiders may bite when physically threatened, but their first instinct is to run when they spot a human. 

Do Hobo Spiders Bite?

Hobo spiders bite when they feel threatened. However, hobo spiders rarely bite people, which is part of why spider experts are still unsure whether hobo spiders are dangerous or not. 

So, unless you try to pick up a hobo spider or get one stuck beneath your clothes, it is improbable that it would bite you.

Are Hobo Spiders Poisonous?

While the CDC once considered hobo spiders as venomous, they no longer list hobo spiders as venomous spiders. The only verified venomous spiders in the USA are black widows and brown recluse spiders.

In the 1980s, several scientific reports indicated that some brown recluse spider bites might have been misdiagnosed and were actually hobo spider bites. However, there were no hard facts to back up this claim – it was all conjecture. 

More recent studies from 2011 revealed that it is unlikely that the hobo spider can cause necrosis. In addition, the results suggested that the venom of a hobo spider is no more harmful than that of a bee or wasp. 

Nowadays, many spider experts believe that hobo spider bites are relatively harmless. Still, some experts believe that only the male hobo spiders can affect humans, and if left untreated, the bite may result in necrotic tissue. 

So, while some scholars and scientists believe that hobo spider bites are pretty harmless, others believe they are very harmful. Unfortunately, because of the potential danger, no one has tested the effect of the bites on humans in a scientific setting, leaving the debate unresolved at this point. 

If you feel a painful spider bite or notice a swelling or white blister, always try to trap or photograph or trap the spider and go to a doctor immediately. If hobo spiders indeed cause necrosis, leaving the bite untreated could result in dire consequences such as amputation. 

Can Hobo Spiders Kill You?

It is improbable that a hobo spider bite could kill you. Still, since no one is entirely positive about the toxicity of hobo spiders, you should immediately go to a doctor if you are bitten by one. 

Right now, biologists and medical doctors need more evidence regarding hobo spiders’ venom. So, it is always a good idea to keep a spider if it bites you. Then, bring the spider to a doctor, especially if your body reacts to the bite. 

What Attracts Hobo Spiders?

Hobo spiders are attracted to warm, dry places like closets and attics. They most often come indoors by accident while looking for a mate or following other insects inside homes. 

Generally, no one wants a hobo spider in their home. These spiders are frightening and of dubious harmfulness to humans.

So, why would a hobo spider come inside your house, and what do they want from you?
