Types Of Spiders You May Find In Your Home During The Winter

The Bay Area is home to several different kinds of spiders. However, some spiders are more common than others. Some of the most common household spiders in the Bay Area include:

  • Wolf spiders
  • Cellar spiders
  • Black widow spiders
  • Garden spiders
  • Jumping spiders

Although all of these spiders are venomous, not all of them are a threat to your health. In the Bay Area, the only dangerous spiders commonly found in and around residential properties are black widow spiders. 

The Problems Spiders Can Create In Homes

Many people would say that spiders have a frightening appearance. However, these creepy pests cause more problems than being scary to look at. One of the problems spiders cause is simply leaving unsightly webs all around your house. These webs can make your home look vacant and unkempt. The most significant problem spiders cause is the threat they pose to your health. Venomous spiders have painful bites that cause redness and swelling. Black widow bites can lead to more serious symptoms, such as nausea, muscle twitches, and difficulty breathing. 

Why Do I Have A Lot Of Spiders In My House During Cooler Months

A common myth you may encounter while researching pest spiders is that they invade homes in winter to escape the cold. However, this is not the case. Many spiders produce a natural antifreeze to help them survive the weather as temperatures drop. They may seek shelter or humidity in the fall and winter, but that’s not the primary reason for spiders to invade.

So what attracts spiders to residential properties during winter? Spiders will take any opportunity to remain close to their insect prey. Many types of insects gather in homes during the winter, which by extension, attracts spiders. If you have insect problems on your property, there’s a good chance that spiders will capitalize on that fact. 

Another reason you might start seeing more spiders in your home during fall and winter is because they’re looking for a mate. Spiders begin looking for partners in autumn, which explains why spider activity increases as the weather cools. It’s likely that these spiders already previously lived on your property but were hidden from sight. You’ve probably only noticed them now that they have emerged from hiding to seek a mate.
