The Most Common Spiders in Denver, Colorado

There’s nothing worse than an uninvited guest that overstays its visit, especially the eight-legged kind. Spiders in your home can be a nuisance and a source of anxiety. The most common types of spiders in Denver are hobo spiders, black widows, wolf spiders, and house spiders.

Hobo Spiders

hobo spiders
Hobo spiders do not have the most dangerous bite of spiders found in Denver, however they are of major concern because hobo spiders are a challenge to exterminate due to their adaptable nature. Originally from Europe, the hobo spider was confined to live in fields, but when the species was unintentionally introduced to the Seattle area roughly 100 years ago, the hobo spider quickly adapted to residential living and became much more abundant due to lack of predators. A bite from a hobo spider is not something to take lightly. It can cause a necrotic wound that resembles a staph infection and take months to heal if not properly treated. With their long legs, common brown body, and yellowish markings, hobo spiders can be difficult to identify and are easily mistaken for more benign relatives.

Black Widows

Black widows are the most infamous and dangerous of spiders found in the Denver area. Thankfully black widows are relatively easy to spot. A female black widow has a signature glossy black body with a red hourglass mark on her abdomen. A female’s abdomen can grow to be up to 1.5 inches long while males tend to be smaller, paler, and can have yellow markings. Female black widows tend to be more aggressive and have a more venomous bite than males.
A bite from a black widow can cause nausea, muscle aches, and paralysis. If you believe you have identified a black widow on your property, keep your distance and contact a professional spider removal company. Do not attempt to remove a black widow by yourself, it is not worth the risk.

Wolf spiders

Wolf spiders earn their name with their furry bodies that can grow up to two inches long. Wolf spiders are unique because they do not create webs, rather wolf spiders roam around looking for prey. They are known for their speed and aggression which makes them more likely to bite. However, no need for extreme alarm. Despite their intimidating name and appearance, wolf spiders are not deadly. Their bite causes minor irritation and is relatively harmless.
Wolf spiders like to stick to woody leafy areas but tend to move inside in early summer and late fall.

House Spiders

House spiders earn their name because they are most commonly found indoors. They are generally harmless, but can become a problem when they reach infestation levels. Most often, their webs are more of a nuisance than the spiders themselves. House spiders are yellowish brown with a signature ‘herringbone’ pattern and their body can range in size from 3/16” to 5/16”.
