Also, while this method may be a knee-jerk reaction, remember that spiders are nimble. You may lose the spider in the chase and be left with a greater anxiety of where the spider managed to scurry off to, she warns. They can bite but “there are no reported cases of medical significance,” Potzler says. Black widows can be found in homes throughout the United States, especially in warm states like Arizona, Florida, Texas, and Nevada.
Western Spotted Orbweaver (Neoscona oaxacensis)
There are a few hundred types of wolf spiders found across North America, and they all belong to the Lycosidae family and Araneae order. The cellar spider has an interesting appearance similar to the daddy long legs. These legs are also flexible, giving the spiders a wispy appearance.
Southern House Spiders Geography
Although it has the shape and size of a black widow, it lacks the distinctive red hourglass marking. However, its venomous bite can cause severe reactions, including pain, muscle cramps, and sweating. Although most house spiders are not venomous, the common house spider is easily mistaken for the dangerous brown recluse. Additionally, the furry brown or black jumping spider looks frightening with its hairy body and white spots, but it is generally not harmful. One of the most abundant house spiders is Parasteatoda tepidariorum, aka American house spider, which is native to North America but now found around the world.
Brown Recluse Habitats and Habits
While they are not likely to bite humans, the bite can be painful. Other than this, their bite is harmless, and these spiders pose no threat to people. The common house spider gets its name because of how common they are across the United States. Nearly everyone has come across one of these insects at some point in time, most likely in their home or apartment.

I can admire those individuals who have no fear of arachnids, but I cannot tell you how many times one has fallen on me while sleeping, reading, walking into my garage, etc. Web-building spiders are the types you’re likely to find in your home. Also called the zig-zag spider, the spider spins a classic spiral wheel-shaped orb web between plant branches in gardens. Therefore, you should take care in Arizona working in the yard or cleaning under furniture to avoid getting a nasty bite from the venomous critters.
If you need assistance to control the population, contact a pest control professional. Domestic House spiders rarely produce enough individuals to develop an infestation. One of their possible benefits is that it can out-compete its relative the Hobo Spider, which is venomous. For some people, a small white blister appears soon after the bite, the tissue may become hard, and develop a red, white or blue lesion.

Like all modern arthropods, the spiders in your attic may be descendants of 7-foot-long marine animals that lived 480 million years ago. True spiders evolved about 300 million years ago, so they pre-date dinosaurs, not to mention us. Spiders have shared our homes for centuries, and they can be model housemates. However, most symptoms don’t last longer than a few hours, with more severe bites causing symptoms to last up to three days. Bites from these spiders can still lead to painful symptoms, and some people can have allergic reactions that need medical attention. Generally, the top part of the abdomen has a dark, v-shaped mark that runs down to its midpoint.
It builds funnel-shaped webs, and is known to prey on pest insects inside homes. Despite this fact, most people cringe at the sight of a common house spider. Seeing a black or brown arachnid scampering across the floor or lurking in a dark corner can send you into a panic. There is also the fear that the house spider is dangerous and could inflict a nasty bite. The western black widow spider is native to Arizona and is one of the most venomous black spiders in the state. You can identify the shiny black spider by the red hourglass-shaped mark on its bulbous abdomen.
They are also covered in dense hairs and have thick, short legs, giving them a scary appearance. Another feature is their eight eyes in three rows, with two prominent eyes in the center. Brown widow spiders are also found in yards under rock piles, wood piles, and other sheltered areas. These brown spiders are common in Arizona, Florida, California, and other southern states.
Funnel weavers, including the hobo spider, are part of the family Agelenidae and are most noticeable in the fall when their dew-covered webs are visible in the morning hours. The tarantulas are common in northern Arizona and create ground burrows. Despite their intimidating appearance, Grand Canyon black tarantulas are not aggressive toward humans. The Alopecosa kochi wolf spider is a large brown spider with mottled patterns on its body and stocky legs. Measuring up to 0.62” (16 mm) long, the hunting spider is most active in spring and generally stays outdoors in Arizona. It has eight eyes arranged in three rows, with two large eyes on the top row.
The large brown southern house spider has an oval abdomen with a velvety appearance, a shiny brown cephalothorax, and long furry legs. Identification of brown spiders can be difficult because they all have very similar markings and colorings. If you suspect the spider you're seeing is a brown spider, give it space. Luckily, they are not aggressive and are not likely to bite unless pinned against skin.
