Hobo Spider Bites: Symptoms, Treatment, Stages and Prevention

The hobo spider (Eratigena agrestis, originally Tegenaria agrestis) is a member of the funnel-web spider family, however it is not to be mistaken with the Australian funnel-web spider.

Individuals make a funnel-shaped construction out of silk sheeting and wait for prey insects to blunder onto their webs at the little end of the funnel. Hobo spiders weave webs in and around human habitations on occasion.

A hobo spider’s body length is roughly 1/4 to 1/2 inch, and its leg span is about 1-2 inches. In the region, there are approximately 200 spider species that look the same.

 The eggs of the hobo spider are laid in September and hatch in late spring. The male hobo spider dies after mating.

 Types of spiders

Black Widow Spiders

Black widow spiders get their name from the popular notion that after mating, females consume their male counterparts. In the natural world, however, this is a rare event.

Brown Recluse Spiders

Male brown recluse spiders stray further from the nest than females, making them more prone to get into shoes or other articles of clothing. Furthermore, while other spider species eat small flying insects, this one likes small cockroaches and crickets.

House Spiders

In her lifespan, a female house spider can lay over 3,500 eggs.

Jumping Spiders

Jumping spiders, unlike most spiders, are active during the day and appear to enjoy the sun. They have the finest vision of all spiders and can detect movement from up to 18″ away. They can’t see well at night, though.

Long-bodied Cellar Spiders

Because of their long, thin legs, cellar spiders are sometimes referred to as “daddy-long-legs.”

Wolf Spiders

Wolf spiders, unlike most spiders, do not hunt with webs. Instead, they use their quick running skills to pursue their prey.

Brazilian Wandering Spiders

Because they are usually found on banana leaves, these spiders are sometimes known as banana spiders. They adopt an aggressive defence stance in which their front legs are raised straight into the air.

Because of the widespread misunderstanding about hobo spider bites, it was once assumed that they might induce necrotic lesions similar to those caused by brown recluse spiders.

These, like the brown recluse, were once thought to be poisonous. However, research over the last 15 years has shown that such cases are rare and that hobo spider bites are typically harmless.

Although the venom delivered by a hobo spider bites is not powerful enough to cause life-threatening consequences, some people may experience pain, headache, acute nausea, and weariness after being bitten.

Hobo spider bites, on the other hand, are no longer thought to induce tissue damage or skin death (necrosis). According to the Centers for Disease Control and Prevention Trusted Source, unlike other spiders that have been shown to cause this disease, hobo spider venom is not hazardous to humans.

This is substantiated by trials in which hobo spider venom was injected into animals and no skin reactions were observed.
