How Did I Get Spiders?

How Do They Get in the Home?

Loose screens and cracks under doors, windows, and other openings are all possible entryways for a spider. These pests may move indoors while searching for food, mates, warmth, or moisture. The presence of insects and other prey in homes is a common reason for spiders to come inside. Spiders are also accidentally introduced inside homes when they are unknowingly introduced to the home’s interior via infested items such as plants, firewood, clothing and other items stored in attics, basements or other storage areas.

How Serious Are Spiders?

While most spiders pose little or no danger to people, some species can deliver venomous bites that may cause medical issues. In the U.S., the two most common venomous spiders are the brown recluse, distinguished by the violin-shaped marking on the top of its cephalothorax, the body part consisting the spider’s fused together head and thorax. The other important venomous spider is the black widow, notable for the red hourglass shape on the underside of its jet-black abdomen.

Behavior, Diet & Habits

Some spiders like moisture and are found in basements, crawl spaces and other damp parts of buildings. Others like dry, warm areas such as subfloor air vents, upper corners of rooms and attics. They hide in dark areas.

Tens of thousands of spider species have been identified throughout the world. These arachnids have eight legs and two body segments. Spiders have three or four pair of eyes. Many spiders have poor vision, but some species of spiders, such as the jumping spider, have exceptional vision.

What do they eat?
They feed on insects, other spiders and any other prey they are able to subdue.

Spiders do not have chewing mouthparts and commonly utilize digestive enzymes in their saliva to break prey down before consuming it. Additionally, the gut of a spider is too narrow to allow for consumption of large food particles. Almost all spider species are predators, although one plant-feeding species has been documented.

Reproduction

Females produce an egg sac from which emerge spiderlings. Spiderlings undergo a series of molts and eventually become adults. Males of many spider species court the female. For example, male jumping spiders perform elaborate dances to attract the attention of a female. Mating can be a dangerous event for males, since they may become a meal for the female afterwards.

Silk
Spiders are capable of producing silk that is elastic, adhesive and strong. This silk is used to spin webs as well as to construct egg sacs and line spider dwellings. The size and shape of spider webs vary by species: some are orb-shaped, while others are funnel-shaped; some webs are orderly, while others appear haphazard. Some spider species live in burrows rather than webs, while others are free ranging and take refuge in crevices.
