There over 30,000 classified species of spiders. The most common spiders in Boulder, Denver, Fort Collins, Loveland, and throughout Colorado are:

  • House spiders
  • Rock spiders
  • Wolf spiders
  • Black widow spiders

Although single specimens of brown recluse spiders are sometimes brought into the state, natural populations are not found in Colorado.

Are spiders dangerous?

The venom of a black widow spider is a neurotoxin and is used as a defense. Black widow spiders do not bite humans instinctively. The black widow spider bite can cause severe pain. Young children and the elderly are especially susceptible to a severe reaction to a black widow spider bite.

Most other spiders in our area do not pose a significant risk, however, a spider bite can be unpleasant and irritate the skin.

Why do I have spiders in my home?

No real reason. Most homes in our area experience spiders in and around there house primarily during the summer months when insect levels are high. Same goes for commercial and industrial facilities. 

How do I get rid of spiders?

Getting rid of spiders can be a tricky task as they are elusive creatures. That's why our service includes everything necessary for one fee.

Our treatment method consists of the following:
