Oh, the many different spiders that can be found in your home. They can be terrifying, with good reason. Spiders are cleaver. They are small. They can hide. While most of the standard spiders found in California and around the United States are entirely harmless there are two infamous venomous types you should know and watch out for. So let’s take a look at how you can identify the brown recluse and black widow and what the potential hazards may be.


Brown Recluse

Brown recluse

The Brown Recluse is one of the very common venomous spiders in the United States. They are so familiar in fact that most people will see one at some point in their life. The Brown Recluse is often confused with other household spiders because of color and size. When you compare Brown Recluse vs. Black Widow in looks, the black widow is hands down easier to identify. Make no mistake though; the Brown Recluse does have a significant symbol to identify them. Brown Recluses are brown in color and sport a violin shape at their eyes and reaches down to their abdomen. However, this is not a reliable method of identification, because some Brown Recluses don’t have the marking. The soundest way to know for sure is to count their eyes. A brown recluse only has six eyes, where most other spiders have 8. If you want to know for sure, get a closer look and count their eyes. The harm that comes from a Brown Recluse bite is the damaging effects to the skin. Their venom causes necrosis, which is when the surface dies. If you have a higher sensitivity to their venom, you could end up with an open sore, and necrosis that takes months to heal. If you see any of these around or in your home, you may want to consider spider pest control.


The Black Widow

Black widow

The most notorious spider award in the United States has to go to the Black Widow. The female black widow that is. This spider is known for their shiny black exterior with a red spot or red hourglass stamp on their bodies. It is pretty difficult to confuse it with any other species. The black widow vs. brown recluse regarding identification, the black widow, wins for ease. The bite of a black widow can make some serious complications, especially in those that are sensitive to the venom. It can cause shortness of breath, numbness at the location of the bite, fever, and nausea. If you find two red bite marks on yourself and are experiencing those symptoms, it is best to see a physician. If you would like to understand how to get rid of black widow spiders, the best solution is to call your local pest control. They will be able to locate them and exterminate.


Honorable Mention For Venomous Spider in California

As far as California spider identification goes for venomous spiders, another culprit to be on the lookout for is The Hobo Spider. These spiders are often confused the Brown Recluse. Their bite pattern and after effects of the bite are very similar. They are spotted in color and have a herringbone pattern on the underside of their body. These are lesser known than the black widow and brown recluse, but their bite can be just as bad.



Not all spiders are dangerous, many are often friendly and just curious. However, the Black Widow, Brown Recluse, and Hobo Spider are venomous. Be familiar with everything these spiders look like, and if you do find them in your home, you should call pest control.
