Types Of Spiders In Colorado

Spiders are friends to few and foes to many. With their creepy-crawly legs and their ability to show up speedily and unannounced, they cause unnecessary amounts of tension and can make a ninja out of just about anyone when they weave their webs at face level. While they’re not so bad outside in their own habitat, when they make their way indoors, it becomes a whole other ball game. Despite their creepiness and their unsightly webs, is there anything to fear or are they harmless? The answer to that question depends on what type of spider you’re talking about. Let’s take a look at some of the more common spiders in Colorado and see if we can better answer that query.

Types of spiders in Colorado

There are over 35,000 species of spiders, but thankfully not all of them live in Colorado. The most common types of spiders in Colorado are house spiders, wolf spiders, and black widow spiders.

House spiders

As their name suggests, house spiders often show up inside homes. The common house spider is typically brown or grey and has darker chevron markings on its body. This arachnid likes to make webs in corners, windows, and above or behind fixtures.

They are not dangerous and rarely bite.

Wolf spiders

Relatively large in size, wolf spiders are often confused with tarantulas, brown recluse, and fishing spiders. Like their name, wolf spiders move very fast to catch their prey. They are found most often in wet outdoor areas, but can easily make their way inside causing a stir in your household. Wolf spiders do not spin webs; they burrow and cover the area with rocks or twigs.

Wolf spiders are not dangerous and are rather shy around humans.

Black widow spiders

Most black widow spiders are a shiny black color with the belly of a female having reddish or orange markings that resemble an hourglass. They are often found in dark corners and undisturbed areas although on more than one occasion unsuspecting homeowners have found black widows in their shoes.

Now, black widow spiders are a bit of a different story when it comes to potential harm. The previously stated spiders can cause an itchy or even painful bite if threatened, but a bite from a black widow spider is venomous. Some reactions are mild but can become severe.
