Have you ever wondered what do hobo spiders eat? While most spiders have a diet that consists of small insects and other arthropods, hobo spiders have an interesting and unique diet that can be intriguing to learn about. In this article, we will take an in-depth look at the diet of hobo spiders and how they feed themselves. We will also explore some of the other fascinating facts about hobo spiders that you may not have known. So, if you are curious to learn more about what do hobo spiders eat, then read on!

Habitat and Behaviour

Habitat And Behaviour

Habitat Behaviour
Hobo spiders are found in temperate areas of the Pacific Northwest. They prefer to inhabit moist, dark areas such as basements, window wells, and other areas with low light levels. Hobo spiders are nocturnal, meaning they are most active at night. They have a web-spinning behavior and they make funnel webs to capture their prey.

Diet Of Hobo Spiders


Hobo spiders feed mainly on insects, including beetles, flies, and grasshoppers.

Other Arthropods

They are also known to prey on other arthropods, such as spiders, mites, and centipedes.

Small Vertebrates

Occasionally, small vertebrates like lizards, frogs, and mice are also part of their diet.

Plant Material

Hobo spiders also consume plant material, such as nectar and pollen.

Impact of Diet on Hobo Spider Populations

Impact Of Diet On Hobo Spider Populations
Hobo spiders are a species of spider commonly found throughout North America. Like most spiders, they feed primarily on insects, making them an important part of the ecosystem. However, the hobo spider’s diet can have a significant impact on its population size.

A study found that when hobo spiders had access to fewer insects, the number of spiders decreased significantly. This indicates that the availability of food is a major factor in determining hobo spider populations. Without enough food, the spiders will not be able to survive and reproduce, leading to a decrease in the overall population.

In addition to food availability, hobo spiders are also affected by the type of insect they eat. For example, hobo spiders that feed on larger insects are more likely to thrive than those that feed on smaller ones. This is because larger insects provide more nutrients and energy than smaller ones.

Hobo spiders are also affected by the temperature and humidity of their environment. When the air is too dry or too hot, the spiders are less likely to survive and reproduce. This can lead to a decrease in the overall hobo spider population.

Overall, the diet of hobo spiders can have a significant effect on their population size. When there is a lack of food or the wrong type of food, the population can decrease significantly. Therefore, it is important to ensure that hobo spiders have access to a plentiful supply of food to ensure their survival and reproduction.

Problems Associated with the Diet of Hobo Spiders

Problems Associated With The Diet Of Hobo Spiders

Hobo spiders are known to feed on a variety of prey, including insects, arachnids, and small vertebrates. However, due to their relatively slow speed and small size, they are often unable to catch larger prey and are thus limited to smaller prey items. This can lead to them becoming nutritionally deficient if they are not able to find a variety of prey. In addition, they are sometimes forced to compete with other spiders, such as the jumping spider, for food, which can lead to a decrease in the amount of food available to the hobo spider. Furthermore, the presence of other predators, such as birds and lizards, can also limit the amount of food available to hobo spiders.

Prey Avoidance Strategies

Prey Avoidance Strategies

  • Hobo spiders are nocturnal, so they hunt in the dark.
  • The spiders use a web to trap their prey.
  • They often hide in dark, undisturbed places, waiting for prey to come close.
  • Hobo spiders are also adept at using their powerful legs to hunt and capture prey.
  • They will also drop down from their webs onto unsuspecting prey.
  • Hobo spiders are also capable of sensing vibrations, which they use to detect prey.
  • Hobo spiders also use chemical signals, known as pheromones, to locate their prey.

Impact of Diet on Prey Avoidance Strategies

Hobo spiders are opportunistic feeders and will consume a wide range of prey, including insects, spiders, and small vertebrates. Their diet can range from small insects to larger prey such as crickets, moths, and beetles. In addition to their prey’s size, hobo spiders also consider the movement and behavior of their prey when deciding whether or not to pursue it.

Prey Strategy
Slow moving insects Hobo spiders may take advantage of the slow movements of their prey to capture them.
Insects that fly Hobo spiders may stay in areas with less air movement, waiting for their prey to settle.
Spiders Hobo spiders may use a combination of ambush and stalking tactics to capture their prey.
Small vertebrates Hobo spiders may use a combination of stalking, ambush, and trapping tactics to capture their prey.

Hobo spiders employ a variety of prey avoidance strategies, depending on the size and behavior of the prey. These strategies include ambush, stalking, and trapping. Ambush tactics involve hiding and waiting for prey to come close, while stalking involves actively following prey. Trapping involves anchoring prey to the ground with webbing. The success of these strategies relies on the size, speed, and behavior of the prey.

Implications for Human Interaction with Hobo Spiders

  • Avoid contact with hobo spiders as they are venomous and their bite can cause minor to serious medical complications.
  • Be aware of their presence and take necessary precautions when coming into contact with them.
  • Wear protective clothing when dealing with hobo spiders and take appropriate measures to reduce their numbers in the home.
  • Pay attention to areas where hobo spiders are commonly found, such as woodpiles, corners, and dark places.
  • Be aware of potential infestations of hobo spiders and contact a pest control professional if necessary.
  • Keep children and pets away from hobo spiders and educate them on the dangers associated with contact with these spiders.

Frequently Asked Questions

What kind of food do hobo spiders typically eat?

Hobo spiders typically feed on a variety of insects, including flies, moths, mosquitoes, cockroaches, and beetles. They sometimes also feed on other arthropods such as spiders and centipedes. Hobo spiders mainly hunt at night, using their web to detect the vibrations of their prey.

Are hobo spiders dangerous to humans?

Hobo spiders are venomous and if they bite humans, it can cause severe pain, swelling, and redness. In some cases, the bite may cause an ulcer or even necrosis, which is tissue death. It is important to seek medical attention if bitten by a hobo spider.

How can you tell a hobo spider apart from other spiders?

Hobo spiders can be identified by their distinctive yellow-brown stripes on their abdomen, and chevron pattern on their cephalothorax. They have an overall mottled pattern, with the coloration varying from gray to yellow-brown. They also have long spinnerets which are used to create webs. The hobo spider is also larger than most other spider species, measuring up to 14 mm in length.

How can you prevent hobo spiders from entering your home?

Hobo spiders can be prevented from entering your home by sealing off any potential entry points such as cracks, crevices, or gaps in walls and around windows and doors. Additionally, keep any vegetation away from the exterior of the home, as this is a common entry point for hobo spiders. Keeping the home free of clutter and other potential hiding spots will also help discourage the spiders from entering.

Do Hobo Spiders Have an Average Lifespan?

Hobo spiders have an average lifespan of 1-2 years. They reach maturity after 8-10 months and die shortly after mating. The female spiders can lay up to 500 eggs during their lifespan, which hatch in early spring.


Hobo spiders primarily feed on insects and other small invertebrates, with their diet varying depending on the availability of prey. Their preferred prey includes small insects, larvae, and other small invertebrates. Hobo spider webs can also capture larger prey, such as lizards, birds, and other small animals. Hobo spiders are not known to attack humans and the venom from their bite is typically not harmful. They should still be handled with caution due to their strong mandibles.
