Spider Facts, Appearance, Diet

It is estimated that there are over 40,000 species of spiders worldwide.

Spiders are arachnids, not insects. They have eight legs and two basic body parts – the cephalothorax and the abdomen. The body part (cephalothorax) contains the eyes and fangs and is where the legs are attached. The abdomen contains the spinnerets, which are used for spinning spider webs. Most spiders have eight eyes in two rows (four eyes per row).

In the pest world, spiders are actually beneficial insects that eat other insects.

House Spiders

House spiders are the most commonly encountered spider inside residential spaces. House spiders typically occupy upper ceiling corners, closets, windows and above or below furniture. House spiders build large webs and prey on other insects. House spiders rarely bite unless provoked. They are more of a nuisance and do not pose an actual real threat.

Garden Spiders

Garden spiders are found outside in gardens where they build strong webs to trap prey. Garden spiders do not display aggressive behavior and are not likely to bite. In the rare case that a garden spider is threatened enough to bite a human, its bite would be harmless.

Black Widow Spiders

Black Widow spiders are black in color with a signature red hour glass on the underside of the abdomen. Contrary to common belief, female black widow spiders do not eat the male black widow spiders after mating. Female black widows are more dangers than male black widows, in that the venom from a female is stronger and they are more aggressive and likely to bite. Black widows often build webs in dark and protected areas like sheds, barns, garages, firewood, boxes and other undisturbed locations.

Black widows lay approximately 300 eggs per egg sac and lay about 10 egg sacs over a lifetime.

Black widow venom is a neurotoxin and a black widow spider bite can cause extreme pain. Children and the elderly are vulnerable to reactions from black widow spider bites.

Brown Widow Spiders

Brown widow spiders were first identified in southern California a little over 10 years ago. The brown widow has a brown and tan striped pattern on its abdomen with an orange-colored hourglass. Like their relatives the black widow, brown widows also establish webs in secluded areas such as empty boxes and containers, fences and the underside of outdoor furniture.

Brown widow spiders lay approximately 120-150 eggs per egg sac and lay about 20 egg sacs over a lifetime.

Brown widow venom is also a neurotoxin, however, according to the University of California Riverside, brown widow spiders are not capable of injecting as much toxic venom compared to black widows.

Brown Recluse Spiders

Brown Recluse spiders are medically significant; however they are not established in California and are instead found in the southwest portions of the United States.

Spider Infestation

Spiders venture indoors when exterior food sources become scarce.

Spider Health Threats and Concerns

Most spiders are nuisance pests and not medically significant, excepting certain species such as the black widow spider and brown recluse spider that have toxic venom. Rather, spiders produce psychological reactions in people who are fearful of spiders and do not want them crawling around their landscape or the interior of their home.
Spiders rarely bite people and usually do so when they are threatened.

Black widow and brown widow spiders are of medical importance in southern California. These widow spiders have toxic venom that produces neurotoxic reactions in individuals that are bitten. Black widow spider bites are painful and can cause localized sweating,
