While spiders may seem the bane of human existence, they do serve a biological purpose on this earth. They are predators but only to other insects. If you’re concerned about the mosquitoes, ants, moths, or flies in your household or business establishment, you can bet the spider is the one for the job. However, the appearance of spiders can also mean they have an ample food supply. On the other hand, an overpopulation of spiders may become problematic in itself. Depending on the type of spider, one adult can lay up to 1,000 eggs at a time. That’s a lot of insects to deal with within a home or business establishment in a short period of time.


All spiders have venom. While some have little or no effect on humans, those with allergies are at risk, and there are two poisonous spiders. If you suspect a spider infestation, it is better to be safe than sorry.


Species Identification

Most spiders hide in similar places: corners, near light fixtures, cluttered areas, beneath furniture, stairwells, closets, garages, etc. The appearances of the different species, however, can differ quite drastically. There are more than 28 species of spider in the state of Colorado. Descriptions of a few of the most common ones are listed below.


Brown Recluse

Brown Recluse Spiders can range in color from yellow-brown to darker brown and can grow to be up to 20mm in diameter. Adults have a violin-shaped marking on their back while the younger spiders do not. As opposed to other species, the Brown Recluse has only six eyes instead of 8. Keep in mind that these guys are poisonous to humans.

Hobo Spider

Hobo Spiders generally have brown and yellow features so they can be confused with Brown Recluse spiders. Look for a brown body with yellow chevron markings on its underside. Also, consider the spider’s web. Hobo spiders have non-sticky, funnel-shaped webs.


Western Black Widow

The Western Widow is another spider that is poisonous to humans. You can recognize adult females by their shiny, black color and reddish-orange hourglass marking on the abdomen. They can grow to be about 16mm in diameter. Males only grow to be about 8mm in diameter. They usually have a light brown body with stripes on the sides of the abdomen. They, too, possess the hourglass marking as the females do, but it is yellow or orange instead of red. 


Orb Weaver

Orb Weavers can grow to be up to 20mm long and vary in color. Black, brown, and orange are common colors. Unlike other species of spider, their abdomens are bulbous. They can also be recognized by their circular webs.
