Another spider commonly mistaken for a hobo spider is the barn funnel weaver spider (Tegenaria domestica). These spiders are normally found in Ohio in basements, barns, sheds, and other buildings.

Interior insect monitors are glue traps that can be a valuable tool used to identify and reduce the number of interior hunter spiders in your home. Place them up against the wall or behind dark, damp areas where spiders hide. There are eight species of mouse spiders in Australia and they are widely distributed across the mainland.
Yellow Sac Spider
The Spotted ground spiders Habronestes and Storena are two genera of spiders in the family Zodariidae. Probably the most notorious of all spiders, Sydney Funnel-webs have a fearsome reputation. In natural settings, the camouflage coloration of this spider helps it avoid many kinds of predators, including salamanders, lizards, small snakes, birds, and small mammals.
Their preferred habitats are in dark spaces in the yard, but they will invade homes in search of warmth during the colder months. Since Harvestmen have no silk glands, they don’t build webs, but tend to also like the same sorts of dark and damp areas. They both eat small insects like mosquitoes and flies, and can therefore be quite effective at pest control. They’re very quick and relatively large, and are often confused with similar species, like tarantulas or brown recluse spiders.
On the less harmful side, American house spiders are found nationwide, but they tend to favor warmer climates like those found in the South. The western black widow is a venomous spider identified by its shiny black body and distinctive red hourglass marking on its abdomen. The females measure 0.55” to 0.63” (14 – 16 mm) and are larger than the males.
The Funnel weavers are common across the United States and are often referred to as grass spiders. This nickname comes from the fact that they are frequently found living in the grass of yards and fields. Though people generally dislike spiders, this species poses a very minimal danger of bites.
The hobo spider is a small brown spider with a characteristic herringbone pattern on its abdomen. The pale brown spider also has identifying features of two lines on the cephalothorax, chevron markings on its abdomen, and eight brown legs. The bold jumping spider is a small, compact spider with a stocky, hairy body, short legs, iridescent chelicerae, and large eyes.
How to Identify Common House Spiders
They are also nocturnal, which means they are more active at night. It is rare that a funnel weaver will bite, as these insects are fast and will run away if threatened or startled. However, in the rare case that this spider does bite, they are said to be mild, with no dangerous symptoms.
Although venomous, the brown widow spider’s bite isn’t as severe as the black widow. The large brown southern house spider has an oval abdomen with a velvety appearance, a shiny brown cephalothorax, and long furry legs. The cellar spider is easy to spot in homes because of its long spindly legs and tiny, egg-shaped, brown body. Although this small brown spider only measures 0.08” to 0.39” (2 – 10 mm), it has an enormous leg span of 2” (50 mm).
It’s a myth that the infamous brown recluse spider (Loxosceles reclusa) is found in California. Researchers from the University of California say that brown recluse spiders have never been able to establish populations in the Southwest. Therefore, painful spider bites in California are likely from black widows or the desert recluse (Loxosceles deserta).
The most popular way to get rid of hobo spiders that have moved into your house is to use Delta Dust in all the tight cracks and crevices where they might be hiding. It has a brown cephalothorax, the front part of the body, that is wider than the longer and narrower abdomen. Flat painted surfaces, smooth metal, porcelain, glass, fine-sanded or lacquered wood will defeat them if they try to climb them. They can only climb rough surfaces such as stone, brick, fabric furniture, and drapes. The females will lay their eggs in September, producing 1-4 egg sacks over a period of about 4 weeks. After laying their eggs, most females will die in late autumn but some may survive the winter to mate again the following year.
Not only does it lack the black widow's red hourglass, however, but its bite is more like a bee sting. American grass spiders are a type of brown funnel weaver spider with an elongated, oval brown body. Identifying features of the grass spiders are the distinctive dark brown bands running down its cephalothorax, mottled brown abdominal patterns, and spiny, orangey legs. Wolf spiders are furry brown spiders with distinctive black bands on their abdomens. Identifying features of wolf spiders are their eight eyes arranged in three rows, banded furry legs, and a flattened head.
