An American house spider is fairly small in size – almost the same size as nickel – and has a large, round abdomen. It’s usually gray with several white markings. This spider builds a very tangled and disorganized cobweb.

An American house spider likes to hide in dark, covered spaces in your house. For instance, you’ll find it in dark corners, under the kitchen cabinets, in the basement, and the garage, especially around the windows. It likes these concealed spaces because they enable it to ambush its prey without warning.

Although an American house spider isn’t dangerous, it can bite you when threatened, crushed, or cornered. Its venom doesn’t pose any serious danger, but sometimes it can cause a mild allergic reaction. This type of spider is commonly regarded as a nuisance pest. The American house spider is particularly predominant in the fall when they enter the house in search of warmth.

2. Wolf Spiders

A wolf spider is a member of the family Lycosidae, which consists of up to 200 species. These species come in different sizes and appearances. The largest ones are about an inch and a half long.

They can be black, gray, or brown, and their bodies are very hairy. Their hairy bodies make them resemble tarantulas. Another notable thing about a wolf spider is the fact that it doesn’t spin cobwebs to trap its prey.

Unlike other spiders, a wolf spider hunts down its prey. That’s why it’s predominant in concealed spaces in the house where insects and other small bugs hide. For example, you’ll find this spider in your basement, shed, garage, kitchen cabinets, and other dark areas.

Since insects are plenty outdoors, it’s normal to find wolf spiders strolling outside in search of food, especially around debris, in cracks around your house, and underneath boards. Wolf spiders prefer to run and hide instead of biting you.

A brown recluse spider belongs to the Sicariidae family and it’s venomous. The spider has necrotic venom, which is essential for medical research and development. You need immediate medical attention when this spider bites you.

This spider is usually 6 to 20 millimeters (0.79 inches) long, but it can grow larger. It can be light to medium brown, blackish grey, or whitish to dark brown. Its cephalothorax and abdomen don’t necessarily have the same color.

The dorsal side of its cephalothorax usually has markings and a black strip that runs from the cephalothorax in a manner that resembles a violin. The neck of the violin faces the back side of the spider’s abdomen. That’s why this spider has been nicknamed violin spider, fiddle back spider, or brown fiddler.

A brown recluse spider has six eyes, instead of the usual eight in other spider species. This creepy crawler prefers to hide in the quiet corners of your house, shed, basement, and vault. You can also find it hiding in your folded clothes, towels, and closed shoes.

This is how many spider bites occur. So, if you reside in an area where brown recluse spiders are prevalent, it’s important to shake out folded clothes, towels, and shoes before you wear them to avoid bites. You should also wear gloves when working in dark spaces in your house like your garage or shed.
