Very few people will cheer at the sight of any insect in their home, but few pests elicit the same level of spine-chilling revulsion as a spider when it suddenly makes an appearance. Arachnophobia is a common fear for men and women, and most people want spiders out of their sight immediately.

The very idea of a potential spider infestation is enough to cause many sleepless nights. Here is what everyone should know about spiders in their homes. 


About 39 different species of spiders are found in California, but not all are interested in human habitats. Many spiders prefer building their nests or webs on the ground, in trees, and in areas away from noise and activity.

Only two species of spiders found in California are harmful to humans. The black widow and the desert recluse (similar to the brown recluse found elsewhere in the United States) are both venomous and can cause illness and pain and other uncomfortable side effects, but their bites are rarely fatal. 


A benefit to having spiders in a home is that they are nature's little exterminators. The average spider eats about 2,000 insects a year. In a home, they are helping to eliminate common problems like fleas, ants and termites.

In fact, spiders sometimes eat other spiders. The cellar spider, the long-legged creature found in most basements and other shaded areas, is even known to eat black widows. In fact, harmless species of spiders are healthy for homes because they may be able to control a population of insects that do spread disease or cause structural damage. 


It is not unusual or even a sign of an infestation if you notice an abundance of spiders in a home during late summer and early fall. Spiders hatch in the spring and are finally fully grown by the end of the summer season so they are more noticeable at this time. Males also begin searching for mates at the same time and are much more active and visible.

A good reason to take note of a seemingly unexplainable boom in their population in the home is if there is a readily available food source. A sudden deluge of spiders traipsing through a home could mean another unnoticed pest infestation may be taking place. If you notice an increase of spiders, it is a good idea to have an inspection from pest control specialists.


You can often control a spider population by dusting and vacuuming regularly. This clears away their webs and usually eliminates a few of the pests as well. Avoiding clutter and not keeping the attic and basement full of storage boxes will also help because it removes a spider’s favorite hiding spot.

There are other ways you can discourage spider populations by taking care of things on the outside of your home. Do not stack firewood near the home or allow bushes, grass and shrubs to grow out of control. Seal up any holes in the siding and trim of the home, repair window screens and make certain doors close tightly.

Logic and reason are not going to convince someone not to be afraid of spiders. It is impossible to feel comfortable in a home when a phobia-causing creature is lurking in corners. If the spiders are suspected to be a venomous species like the black widow or a recluse, it is important to find immediate help.
