In Phoenix, Arizona, spiders are one of the most common pests that people have to deal with. As a result of the warm climate, spiders are a year-round issue for many Phoenix residents. Spiders are one of the sneakiest pests because of the fact that they are nocturnal. During the day, they often hide in their web, cracks, crevices, or dark corners. More often than not, they will dash off if frightened unless they are protecting their eggs or their young. This guide will help you identify popular spiders in the area. If you’re experiencing a spider infestation contact our Phoenix pest control experts today.

Common Spiders in Phoenix, Arizona

There have been 27 unique species of spiders confirmed to be in Arizona. However, here are six popular spiders that are in the Phoenix area: the black widow spider, the Arizona brown spider, the southern house spider, the wolf spider, and the tarantula.

Black Widow Spider

These spiders have shiny black bodies and are roughly ½ inch to ¾ inch in size.

You can identify a female black widow spider by the red hourglass shape on its abdomen. Male black widow spiders are often much smaller and usually have spotted yellow and red bands on their backs.

They usually hide under stones, wood piles, clutter found in garages, sheds, and other low traffic areas.

If you happen to get bit by a black widow spider, it is important that you seek medical attention, as they can cause serious illness to the central nervous system.

Arizona Brown Spider

The bodies of these spiders are roughly ⅓ inch with a leg span of about 1-1½” long.

This spider is a recluse spider that is very similar to the infamous brown recluse often found in the midwest.

Unlike most spiders who have 8 eyes, the Arizona brown spider has six eyes arranged in pairs of three. Another defining characteristic of this spider is that it doesn’t have any stripes or bands. They also have uniformly light-colored legs and abdomen, which varies from tan to dark brown depending on what it has been consuming.

These spiders prefer dark, undisturbed spaces such as under furniture, in closets, sheds, garages, and under boxes.

Bites from recluse spiders are often “dry” bites. This means that no venom is injected and the victim has no side effects. In extreme cases, if the bite is injected into fatty tissue, it can lead to the death of skin cells in the area where you were bit.
Reactions to getting bit by a spider vary greatly with each individual, so it’s important to seek medical attention.

Southern House Spider

Both male and female southern house spiders may reach up to 2” long.

These spiders are aptly named because they most often infest homes. They look very similar in size and color to the brown recluse and are often mistaken for the more dangerous species.

If they make their way inside, you can often find them in secluded corners, crawl spaces, cracks, crevices, and among clutter.

They are not aggressive, however, they will bite humans if they feel threatened. These bites are not dangerous and will heal quickly.

Wolf Spider

Female wolf spiders are roughly ⅜ – 1 ⅜” long and males are about ¼ – ¾ inches long.

They prefer to be outdoors and can often be found near pools, lakes, rivers, and canals. If you happen to see them inside, it is likely that they’ve wandered in by accident. However, once they’re inside, they will most likely stay there because of the potential for nutrients and the lack of competition.

They do occasionally bite, however, their venom will most likely only cause numbness and is not lethal to humans.

Jumping Spider

Jumping spiders are relatively smaller in size compared to the previously listed spiders. On average, they range from ⅛ – ⅜” inches long. These spiders can also be identified by the four eyes across their forehead.

They can typically be found on logs, rocks, tree trunks, window screens, and exterior walls

They do bite on occasion, however, their venom is usually not dangerous or fatal to humans.

Tarantula

One of the larger species of spiders, the body of a tarantula may be up to 2 ½ inches in length and have a leg span of up to 4”.

These spiders like to keep to remote locations in the desert surrounding the Phoenix metropolitan area. The majority of tarantula species hide in burrows which they’ve dug using their fangs and fore-legs.

Tarantulas are actually quite calm and rarely bite people. However, their bite may feel similar to that of a bee sting.

Am I Being Bit at Night By Spiders?

Most likely not. While most spiders can bite, they are typically not aggressive. This means that they do not go out of their way to attack you or one of your loved ones.

The most common instance where a spider would bite someone is if the spider was threatened or startled.

What you think may be a spider bite could be any number of things. Bedbugs, mites, fleas, ticks, mosquitoes, and biting midges are all arthropods that do bite humans.
