Common House Spider Types


Spiders come in many different varieties, and they are prevalent in houses all around the world. Two out of every three homes in the US have infestations. Unless provoked, they are typically regarded as being non-threatening. When we are bitten, the venom is typically not harmful enough to injure us permanently.


Here are some of the most typical kinds of house spiders and information on how to recognize them.

Yellow Sac Spider

The species Cheiracanthium can be found everywhere. They pose little threat to humans and seek shelter in your home throughout winter. In their silky sacs, they hide in floor corners or ceiling walls. 14-inch spheres with a yellow/green tinge.

House Spider in Black

The Grey House Spider, also known as Bauman insignis, is widespread in Australia and New Zealand. Despite being poisonous, the black house spider is not thought to be dangerous to people. They can be located in your home in any location where their prey might be, including as corners, windows, or next to bright lights. They can reach a 1 14-inch leg spread and are black.

Brown House Spider

The Steatoda Grossa, often known as the Cupboard Spider, is widespread. One of these spiders’ bites can result in blistering, fever, and muscle spasms for a few days, but most people won’t require medical attention. They lack eyesight and rely primarily on vibrations to build webs. A Brown House spider’s female counterpart differs significantly from its male counterpart in appearance, having a wide, circular body that is dark brown and frequently mistaken for the Black Widow spider. The male is slimmer than the female and grows to a length of 4 to 10 mm. The female grows to a length of 6 to 10 mm. If you feel that you have Black Widow Spiders call pest control for black widows immediately!

Domestic House Spider

Tegenaria Domestica, also known as the barn weaver, is a global species. They create their webs around window sills or corners and pose little threat to people. Since they are light-sensitive and prefer gloomy environments, attics, basements, and crawl spaces are where you’ll probably find them. Domestic house spiders have long, flattened, straight bodies. Males are between 6 and 9 mm in length, and females range from 7.5 to 11.5 mm.

Hobo Spider

Aggressive House Spiders, also known as Tegenaria agrestis, may be found all over the world. The Hobo has a terrible reputation for being aggressive and harmful since its bite is sometimes mistaken for those of deadly Brown Recluse spiders. Only if there is no threat from other spiders will they enter your home. They range in size from 11 to 14 mm, are light brown, and have a slender body.

Standard Cellar Spider

Daddy Long Legs, also known as Pholcus phalangioides, is widespread around the world. They will seek out your home in cooler areas since they cannot thrive there. There is a persistent misconception that Daddy Long Legs spiders are the most deadly in the world but lack the long enough fangs to pierce human skin. Both assertions have been refuted. The venom from a bite will only produce little burning, and it is safe for both people and small animals. The creature’s legs can grow up to 4 inches long, and its little, oval body is tan in color.

Standard House Spider

Parasteatoda tepidariorum, the American House Spider, is found worldwide. They pose no harm to people and will typically allow you to put your hand near them. Under window sills and in wall corners, they can be seen spinning webs. The usual body length of common house spiders is 6 mm, and their leg spans can reach a length of more than an inch. They have a dull brown color.
