The House Spider
House spiders are found throughout the world. It is a generic name for the different species commonly found in the houses. There are many recognized species of house spiders, although the most commonly found is the common house spider. They have derived their name from their common presence in human residents.
HOW TO IDENTIFY HOUSE SPIDERS
House spiders are usually brown or grey in color and are found behind furniture or in storage places or basements.
Appearance, Behavior, and Signs
Female house spiders are about 5 to 8 mm in size, while male spiders are only about 4 mm. They have eight legs, like all other spiders, and have single lens eyes. Their body is divided into two major parts: the cephalothorax and the abdomen.
House spiders are quite harmless to humans but can be scary to see and cause discomfort by mere sight. Also, they keep making webs around your house until they find the perfect spot. So they give you extra cleaning work.
Basically, you can be sure of a house spider infestation if you see too many spiders in your house or spider webs.
