Most Common Spiders For Homeowners To Look Out For In Riverside


If you have ever seen a spider on your couch and wanted to burn down your whole house rather than kill it, you might have a full-fledged debilitating fear of spiders. And that's ok. Compass Pest Management is here to be your Riverside pest control company and take care of the spiders for you!

Not all spiders are harmful. In fact, we want spiders everywhere because they are a vital part of our ecosystem. Without them, we would be overrun with other insects. Keep reading to learn about the most common household spiders in Riverside, the most dangerous spiders in California, signs of a spider problem in your home, and how to take care of these eight-legged pests.

Three Common Spiders In Riverside

There are spiders everywhere in Riverside, and that's not a bad thing. Like bees, all spiders are an essential part of our ecosystem and life on earth. But that doesn't mean we want to see an infestation of them, especially in our homes. Here are the three most common household spiders in Riverside that are not dangerous to humans, even if they bite you:

  1. Jumping Spiders: These tiny, half an inch or smaller, fuzzy insects are known for their impressive eyesight. They inject venom into their prey but rarely bite humans unless threatened. 
  2. Wolf Spiders: Wolf spiders can be so hairy and large that they often get confused for tarantulas, although the size and coloration can be quite varied. They are most active after dark and move very quickly, making them hard to spot. They are not aggressive but will bite you if threatened. 
  3. Orb Weaver or Garden Spiders: It is good to see these spiders in your yard because they prey on insects. They spin large elaborate webs, which makes them pretty easy to spot, hopefully, before you walk into one. 

Even though these species of spiders are harmless to humans, you do not want them to infest your home.

Dangerous Spiders

If any of the following three most dangerous spiders in California bite you, seek medical attention immediately. If untreated, the tissue and skin around the bite mark can rot and die. People with specific medical conditions are at high risk for circulatory failure.

  • Black Widow: In the case of this species, the males are harmless, but the females are venomous and aggressive. The female's body is about half an inch long with a round black, shiny abdomen and distinctive red hourglass figure on its underside. The males are half the size and do not have the same markings.
  • Brown Widow: Just as poisonous as the black widow, but not as aggressive, female brown widow spiders also have an hourglass figure on the underside of their abdomen, although it is orange. As the name suggests, they are mottled brown and tan.
  • Desert Recluse: Not to be confused with a brown recluse that is not native to California, the desert recluse is not aggressive but will bite when threatened, and their bites are very toxic. They are tan or sandy in color with a fiddle-shaped body.

Contact Compass Pest Management immediately if you see any of these dangerous spiders around your home or property.

How To Identify A Spider Problem

Although most spiders tend to be more active at night or try and stay hidden, there are a few telltale signs that indicate your home may have a spider problem:

  1. Finding egg sacs
  2. Noticing more moisture or humidity in your home
  3. Unexplained bite marks
  4. Noticing fewer insects in your home
  5. Seeing webs

Take notice of any unusual activity and inform your pest control expert so they can take the right steps.

How To Take Care Of A Spider Infestation
