Black House Spider Facts, Venom & Habitat Information

Most people and even medical doctors over-diagnose “potential spider bite” based on symptoms such as redness, swelling, cramps, severe pain, or even necrotic lesions. These are usually caused by other factors including diseases or medical conditions and bacterial skin infections. Both spiders and insects are arthropods, meaning their skeletons are on the outside of their bodies (exoskeleton). The common name 'Badge Huntsman' comes from the distinctive, often brightly coloured badge or shield on the underside of the abdomen. Black House Spiders are timid animals and bites from them are infrequent.

Wolf spiders are robust, fast and agile hunters that rely on good eyesight to hunt, typically at night. However, it is classed as a harmless indoor brown spider because it’s not aggressive and only bites if you grab or squeeze it. Additionally, the toxins in the venom aren’t dangerous to humans. Female wolf spiders are very maternal and will carry their eggs in a sac on their back. When the eggs hatch, the female will carry the hatchlings on her back until they are large enough to hunt on their own.

Where Do Wolf Spiders Live?

The brown recluse, or “fiddleback,” can have a violin-shaped mark on its cephalothorax (the front part of the body). But brown recluses are more easily distinguished from wolf spiders by the number of eyes. Other names for the brown recluse spider include brown fiddler, violin spider, or fiddleback spider. Although the violin markings on its head are an identifiable feature, other harmless spiders also have similar markings. However, a unique characteristic of the brown spider is that it has six, not eight, eyes like most spiders.

Joro spiders are large with brightly colored distinctive yellow, red, and black patterns. They were recently spotted in the southeastern U.S., particularly around homes with gardens. These spiders build large, orb-like webs and are known for their vibrant, colorful appearance. Woodlouse spiders have reddish heads and gray abdomens with robust bodies. They can be found in damp areas under rocks and logs outdoors, in basements, or under floorboards in homes.

True to their name, funnel weavers make funnel-like webs along the ground in which the spider hides in. When a prey species crosses the web and vibrates it, the spider will jump out and grab its new meal. Because of this feeding strategy, funnel weaving spiders are designed to be incredibly quick and most rarely leave their webs.

Anyone who has been bitten by a brown recluse spider should seek emergency medical attention, according to MedlinePlus, a service of the National Library of Medicine. The black house spider is a robust spider with a dark, charcoal-gray abdomen and white speckles. In addition, the spider has a characteristic velvety blackish-gray body and furry legs. Its large, egg-shaped abdomen and color give it the appearance of a tarantula.

Although most house spiders are not venomous, the common house spider is easily mistaken for the dangerous brown recluse. Additionally, the furry brown or black jumping spider looks frightening with its hairy body and white spots, but it is generally not harmful. Fishing spiders look very similar to wolf spiders in regards to size and coloration. However, fishing spiders tend to have much longer legs, relative to the rest of their bodies and have alternating brown/black bands on their legs.

Nonetheless, thin legs are a physical trait of wolf spiders in the genus Acantholycosa. The difference between the two groups is the number of tibial spines, or hair like protrusions from the tibia on the first leg. Most Raidosa species measure around one inch in length and share the physical characteristic of having distinct light stripes on a brown body. The picture at the top of the page highlights a chevron pattern on the bottom of the abdomen. Despite the name, the rabid wolf spider (Genus Rabidosa), is not an aggressive, rabies carrying scourge of the earth. In fact, rabid wolf spiders are a fairly common and docile eastern wolf spider genera.

In addition, the six-eyed spider has a distinctive violin pattern on its cephalothorax, making it easy to distinguish from the common house spider. Brown widow spiders measure 0.47” – 0.6” (12 – 16 mm) long, making them slightly smaller than black widows. Like all widow spiders, the brown widow has long, extended legs that are tan with dark brown bands. The black widow spider is easily recognized by its shiny black body with a red hourglass marking. Black widows with red markings have a bulbous abdomen, long glossy black legs, and a small head. Depending on the species, the abdominal marking on the black spider’s underside can be pinkish, orange, or deep red.

They are "mostly nocturnal and often mistaken for tarantulas," Sewlal said. These spiders spend most of their time on the ground, but they can climb trees or other objects if they need to. Their habitats include stream edges, gravel and low vegetation, according to the Missouri Department of Conservation. Wolf spiders are a family of mostly large, hairy and athletic arachnids. Rather than catching their prey in webs, wolf spiders chase it down similar to the way a wolf does, although these spiders hunt alone, not in packs. They typically live on the ground, though some are known to climb partly up trees to catch their prey.

Additionally, it's a good idea to keep any pets or young children away from the application site for the recommended time after spraying or applying pesticides. Most species of wolf spider are considered to have stable populations, although the exact populations are not known. Despite this, some of the species located on small islands such as Desertas and Saint Helena are critically endangered, according the IUCN Red List.
