Spiders in Denver, Colorado: A Comprehensive Guide
Denver, Colorado, like many urban areas, is home to a variety of spider species. While the thought of spiders might make some uneasy, most of the spiders found in Denver are harmless and play a beneficial role in controlling insect populations. This article provides an overview of common spiders in Denver, their potential risks, and how to manage them.
Common Spider Species in Denver
Several spider species are commonly found in and around homes in the Denver area. Here are a few of the most prevalent:
House Spiders
House spiders (primarily of the Parasteatoda tepidariorum species) are among the most frequently encountered spiders indoors. They are generally small, brownish in color, and build messy, irregular webs, often in corners or undisturbed areas. They are not aggressive and their bite is considered harmless to humans.
Wolf Spiders
Wolf spiders are large, hairy spiders that are often mistaken for tarantulas. They are ground-dwelling hunters that do not build webs but actively pursue their prey. While their size can be intimidating, they are not considered dangerous, though their bite can be painful, they are typically reluctant to bite.
Cellar Spiders
Also known as “daddy long-legs” (though technically not all daddy long-legs are spiders), cellar spiders are easily recognizable by their long, thin legs and small bodies. They are commonly found in basements and other dark, damp areas. They are harmless to humans and are known for vibrating their webs when disturbed.
Jumping Spiders
Jumping spiders are small, active spiders with excellent vision and the ability to jump long distances. They are often brightly colored and are fascinating to observe. They are not aggressive and their bite is not considered medically significant.
Black Widow Spiders
Although less common than other species, black widow spiders (Latrodectus hesperus) are present in Colorado, including the Denver area. They are easily identified by the characteristic red hourglass marking on the underside of their abdomen. While they are generally reclusive, their venom is potent, and their bite can cause significant pain and requires medical attention. For more information on black widow spiders, you can refer to Wikipedia’s article on the Latrodectus genus.
Are Spiders in Denver Dangerous?
Most spiders in Denver are not dangerous to humans. Their bites are either too weak to penetrate human skin or their venom is not potent enough to cause significant harm. However, as mentioned above, the black widow spider is an exception. If you suspect you have been bitten by a black widow spider, seek medical attention immediately.
Managing Spiders in Your Home
If you are concerned about spiders in your home, there are several steps you can take to manage them:
- Seal cracks and crevices: Prevent spiders from entering your home by sealing any cracks or crevices in your foundation, walls, and around windows and doors.
- Reduce clutter: Spiders prefer dark, undisturbed areas. Reduce clutter in your home to eliminate hiding places.
- Maintain a clean environment: Regularly vacuum and dust your home to remove spider webs and egg sacs.
- Control insects: Spiders feed on insects. Controlling insect populations in and around your home will reduce the food source for spiders.
- Professional pest control: If you have a significant spider infestation, consider contacting a professional pest control company for assistance.
