Jumping spiders are diurnal, and particularly abundant in grassland and prairie environments, where they prey on small insects. They can enter a home on clothing or plants, but are unlikely to establish themselves once in your home. Domestic House spiders rarely produce enough individuals to develop an infestation. One of their possible benefits is that it can out-compete its relative the Hobo Spider, which is venomous. Domestic House spiders are all over North America, as far north as Maritime Canada and as far south as Louisiana.
Spotting House Spiders
Head to the ER ASAP if you suspect you’ve been bitten to get immediate treatment. Widow spiders are not one of the most common types of house spiders, but are the species most people worry about. If you see a spider in your home, it is likely not a widow spider, but it's still a good idea to know what to look for and how to avoid disrupting them. Reactions vary from person to person, but hobo spiders are not considered toxic to humans, according to the University of California's Pest Management Program.

They can help identify the type of house spiders and provide specialized treatments. A large spider with a brown cephalothorax (the fused head and thorax) and a tan-coloured abdomen that often has a characteristic ‘herring bone’ pattern.

Contact a licensed pest control professional if you suspect a spider infestation in the home. You can find a professional with the helpful zip code search below. Although most house spiders are not venomous, the common house spider is easily mistaken for the dangerous brown recluse.
When it comes time to breed, the female lays her eggs in a brown-colored cocoon. She can breed multiple times in a single season, and each cocoon produces between 150 and 200 eggs. After hatching, the young spiders hide in the web for a period as well. Tarantulas are often perceived as large, aggressive spiders with the potential to cause serious harm. However, most tarantulas have relatively weak venom that affects smaller prey but is not dangerous to humans. Bites from tarantulas can be painful due to the size of their fangs, but the effects are usually limited to mild discomfort or swelling.

The three types of harmful, venom-filled spiders are the western black widow, desert recluse, and Chilean recluse. In this article, spider measurements are typically of body size, not leg span. Therefore, spiders with long legs and small bodies, like the brown widow spider, will appear significantly larger.

Bigger females can also attract baby skinks inside their web by leaving fly remains hanging in it. Once its food dries out, the spider usually drops it to the floor in order to free space in its web, instead of destroying and rebuilding it or changing its location. Hobo spiders are a type of brown funnel web spider with distinctive chevron, V-shaped patterns on their abdomens. Brown widow spiders measure 0.47” – 0.6” (12 – 16 mm) long, making them slightly smaller than black widows.

Cellar spiders can bounce in their webs, which is a defense mechanism they display when threatened or scared. Jumping spiders are one of the smallest spiders encountered throughout the United States, and they are commonly seen in various regions of the country. They are frequently found inside homes, as well as gardens and sheds. Adults can be between 6 and 11 millimeters in size and are covered in yellowish hairs. These animals are commonly found in sheds and barns and have been known to live for seven years. As the name suggests, this species prefers living in dark regions of houses where it can collect small insect prey.
Identifying features of common house spiders are their eight legs, body shape, distinctive markings, color, and presence of hairs. However, the black widow with its distinctive red hourglass marking is an exception. As with nearly all other spiders, the ones you usually see, hanging in their webs, are females. The males are small and are usually only seen when courting or mating in the female’s web. The egg sacs of this species are familiar tan or gray dry-looking spheres, usually with a pointed or slightly elongated tip making it look rather pear shaped.
When an insect becomes entangled in the web, the spider darts out of the narrow end and bites its prey to envenomate it, then pulls it back down to feed at its leisure. Check out this video for more information on getting rid of hobo spiders in your home and on your property. The probability of a Yellow Sac Spider infestation increases significantly in the fall, as they generally experience a population boom around that time.

Hobo spiders weave funnel shaped webs in which to catch their prey.
American House spiders have a bulbous abdomen and are brown in color with white or darker patches and lines.

Nearly everyone has come across one of these insects at some point in time, most likely in their home or apartment.
