You’re enjoying dinner with your family when a spider the size of a half-dollar races across the floor and under the table. Even more terrifying — you wake in the middle of the night to find a large, hairy spider sharing your bed.
Types of Common House Spiders (With Pictures) – Identification Guide
Many species of fishing spiders live near water and often catch small fish, aquatic insects and tadpoles. One exception is the dark fishing spider (Dolomedes tenebrosus) which lives in wooded areas and occasionally seeks refuge in basements. The females are shiny black with a red hourglass on the bottom of her abdomen while males have a more vibrant pattern on their abdomen consisting of many red and white spots. Male black widow spiders are rarely encountered and are not known to bite humans.

The brown, biting spiders have a tan to medium brown body with a recognizable violin-shaped marking on their cephalothorax. Wolf spiders are active hunters and cause the greatest concern when encountered in homes. These spiders have excellent vision, allowing them to see humans approaching them, at which point, they flee. Many wolf spiders are nocturnal and use a reflective structure to maximize vision at night.

Bite
These webs are used to attract the prey and suck it into the funnel, after which the spider will apply its venom to kill the prey. The wolf spider can grow to up to 35mm in size, while the common house spider will only grow to about 11mm. If you don’t know what spider you’re looking at, if the spider is larger than a nickel, then you’re probably looking at a wolf spider. Wolf spiders mainly eat ground-dwelling insects and other spiders. They tend to hunt at night, either leaving their burrow or hiding place and stalking their prey or lying in wait and pouncing when an unsuspecting insect walks by. Some wolf spiders can take on insects larger than they are, and even small amphibians.
Which is More Venomous?
When the spiderlings hatch, they are carried around on the females back until they are ready to disperse by ballooning or on the ground. Such a high degree of parental care is relatively unusual among spiders. Let’s first take a look at some of the similarities between the wolf spider and the house spider. Wolf spiders are usually brown, black or gray with black or brown stripes. They’re also hairy, leading some people to confuse them with tarantulas. Instead, they use their front legs as antennae and hunt small insects.
Wolf Spiders: Pictures and Identification Tips
The cellar spider is a harmless, brown spider with a small rounded abdomen and long thin tan-colored legs. American house spiders are common in corners of rooms, window frames, and furniture. You’ll also find them in dark places like attics, crawl spaces, under furniture, and sheds. Funnel weaving spiders look very similar to Wolf spiders, but they make webs and have three rows of eyes.
Hunting Technique
Properties located in areas where insects are numerous, such as by rivers, lakes, or fields, are more likely to have large numbers of spiders. Remember that spiders are not harmful so tolerate spiders when possible. When just small numbers are found, the easiest control is to capture and remove them. Control of spiders is best achieved with an integrated approach that includes different non-chemical methods and occasionally insecticides. The type of spider can influence how you control it so it is important to identify the spider that is found. Crab spiders are often found outdoors on flowers, stems or leaves.
When the other spider comes out to investigate its “catch”, the cellar spider will eat the unsuspecting spider. Cellar spiders are commonly found in homes, but they typically stay in one place and don't bother people. Wolf spiders' maternal behavior doesn't stop with the egg sacs. "After hatching, the spiderlings climb on their mother's back, and she carries them around for several days," Sewlal said. After this, the spiderlings leave their mothers and go off alone.
Also, the spider has a huge leg span of 1.1” (28 mm), making it appear larger. Identifying features of the common American house spider are its bulbous dark brown body with mottled patterns, long creamy-white and tan legs, and a small, brown-colored head. Crab spiders are not active hunters and use the art of camouflage to snag their prey. Crab spiders are named after their crab-like appearance with large front legs that are often held out to the sides of their body. These spiders come in all different colors, many of which are specially adapted to their hunting grounds. For example, the goldenrod crab spider is a bright yellow color which allows it to easily blend in with the yellow petals of goldenrods.
They have three rows of eyes — four small eyes on the bottom row, two giant eyes in the middle, and two medium-sized ones on the top and a little to the side. They got their name because, like wolves, they’re fast, agile hunters. But unlike wolves, Thome says, wolf spiders are solitary and do not hunt in packs. Hobo spiders are common in houses in the northwestern United States. They enter homes through cracks in the fall and will find dark, damp places to hide. They are often found in basements, under bathtubs, or in wall crevices.

Once the male has made sure that the female will be receptive, he will approach and inseminate her with his palps. Wolf spiders eat mostly ground-dwelling insects, such as crickets and other spiders. Large females may take on small amphibians and reptiles, according to BioKids. Some species chase down and seize their prey, while others wait for prey to walk by and then ambush it. Wolf spiders often jump on their prey, hold it between their legs and roll over on their backs, trapping their prey with their limbs before biting it and injecting their venom.
The other three pairs of eyes are relatively small in comparison. Parson spider is a medium-sized spider (1/2-inch long) with a brownish body and gray abdomen with a white band running down over half the length of its abdomen. Sac spiders hunt at night, feeding chiefly on small insects, and hide during the day in a silken tube or sac, from which they take their name.
A Black House Spiders bite may be quite painful and cause local swelling. In a few cases skin lesions (Necrotising Arachnidism) have developed after multiple bites. In the Australian bush, Black House spiders are usually found upon rough-barked trees which provide good shelter for their retreats among the cracks in the bark.
Although technically not classed as a true spider, harvestmen have many of the characteristics of spiders. Usually, harvestmen are small, with their bodies not growing more than 0.28” (7 mm) long. However, they have a characteristic large leg span, sometimes up to 6.3” (160 mm) in length. There are thousands of species of jumping spiders with common characteristics. The small, white-spotted spiders measure 0.04” to 1” (1 – 25 mm) long.
Apart from the Six-spotted Fishing Spider, identifying Dolomedes fishing spiders often turns into an exercise in guessing. Five species are present in the Northeast and New England forest areas. Four of those species have ranges that extend through most of the East and Midwest. Over a dozen different genera, consisting of over two hundred species call some part of the United States home, making them one of the most abundant and commonly seen spiders. Insignis is native to Australia but has been introduced to New Zealand and Japan.[1] It is widely distributed throughout Australia and New Zealand.
