Spiders 101

Commonly known as spiders, arachnids have eight legs, two body segments and, typically, poor vision, despite having three or four pair of eyes. There are exceptions, however, such as the jumping spider, whose vision is extraordinarily good.

Spiders don’t chew their food because they don’t have the facial apparatus to do so. Rather, they break it down with digestive enzymes in their saliva, in part because spider stomachs aren’t wide enough to handle large food particles. There is only one known herbivorous spider; the rest are predators.

Spiders make their webs out of silk, which is sticky, stretchy and strong. The webs are used for hanging egg sacs and as a lining for their dwellings. The construction of the webs varies by size and shape according to species, some appearing orderly, some messy, some round, some funnel-shaped. There are some spiders that burrow for their homes instead of constructing webs, and still others who roam from crevice to crevice.

How Do They Get Into a House?

Usually by just walking straight in, though an open or poorly screened window or door, and through caps around door and window frames. They don’t enter homes looking for housing so much as looking for food. They’ll also get inside as stowaways in boxes or other items taken from outside into the home.

Black Widow Spider

The southern black widow spider is shiny and black.

They have painful bites.

Brown Widow Spider

Brown widows are gray or brown.

They have the same hourglass markings, but they are on the top of the abdomen and are yellow or orange.

Fully grown brown widows grow to between 1 and 1 ½ inches.

Wolf Spider

As the name suggests, wolf spiders and big and hairy, in wolf-like colors (brown, gray, black).

They can grow anywhere from a half-inch to 2 inches in length.

Wolf spiders aren’t poisonous, though some people have reactions to their bite.
