The brown widow has spread to many other parts of the world, including parts of Australia, Japan, and the Caribbean. Another identification characteristic is the type of web that the spider weaves. For example, brown cellar spiders create irregular webs, while others, such as orb-weaving spiders, create intricate orb webs unique to their species. Spiders’ habitats and behaviors can also provide clues for identification purposes. Surprisingly, most people living in infested homes, even when the invasion is heavy, don’t report spider bites.
Cellar Spiders
More commonly found in homes are harmless brown house spiders, such as the cupboard spider, American house spider, basement spider, and aggressive house spider. While they do bite, brown spiders are considered a nuisance pest rather than a serious threat. It’s important to remember that spiders belong to the class Arachnida, which includes all eight-legged spiders, and are not insects. Brown recluse spiders are venomous, and their bite can be dangerous. While not brown house spiders, black widow spiders are dangerous as well. House spider is a term for several Arachnida species typically found in homes.

In 2001, more than 2,000 Brown Recluse Spiders were found a in a Kansas home, yet the residents had never been bitten, despite living there for years. Wolf spiders have excellent eyesight with two rows of four eyes each, making them exceptionally adept at night hunting. The brown recluse spider seldom bites, and the bite won't kill you. Common house spiders might be seen on multiple webs close together or a web with more than one spider. If house spiders find a good spot with plenty of food, they do not mind if another spider produces a web nearby.
This spider has six eyes, which is unusual compared to other spiders that typically have eight or twelve eyes. The brown recluse spider can range in size from 0.24 to 0.8 inches (6 to 20 mm), and its spindly legs stretch out in a star formation compared to its body. Brown spiders are a common sight in households, and they can be quite terrifying to encounter.

Aim to remove spiders, egg sacs, and webs from your house to reduce numbers long-term by using a vacuum, broom, or spider brush with an extendable handle. Common house spiders possess poor vision and cannot detect any movement more than three to four inches away.
Their bite can cause necrosis, which is the death of living tissue. It isn’t uncommon for victims of these spider bites to require skin grafts on the affected area. While they’re not as toxic as the brown recluse, yellow sac spiders are known for their painful necrotic bite. When they come into contact with human skin, they can bite repeatedly if not removed.
Brown, black, and yellow are the main colors of this spider. Wetland Giant Wolf spiders have a dominant brown or brown-green color. The cephalothorax of the species has the same brown, black, and white coloring with black marks on the lower side.

However, most of these spiders are harmless and are usually found in basements, attics, or outbuildings. An aggressive spider found in California, Hobo Spider can be often confused with other house spiders because of its brownish color. However, they have V-shaped chevron stripes on their abdomens and are larger between mm.

The eyes of these spiders reflect the light of the flashlight unlike with many other spiders. Cross Orbweavers have a cannibalistic nature as females eat mares while mating or after mating. This species has a necrotic venom which means medical attention is required after a bite. Coloring differences might also be seen between male and female spiders. If the spider has conspicuous thick spines on the legs, it is NOT a recluse.
