If you suspect the spider you're seeing is a brown spider, give it space. Luckily, they are not aggressive and are not likely to bite unless pinned against skin. It is most common for brown recluse bites to happen on the arms, hands, and feet while getting dressed or cleaning storage areas.
Common House Spider Bites
The western black widow is found throughout California—in hot, dry climates to mountainous terrain. Their favorite hiding places are in woodpiles, rock crevices, cracks in walls, and garages. The noble false widow spider is invasive along the southern coastal regions of California. Although the dark-colored spider bites, the effects are no more serious or painful than a bee’s sting. It is found in the southern United States, particularly in Florida, California, and Texas. The brown spiders spin messy cobwebs in secluded areas such as attics, roof eaves, garages, and under furniture.
Geographic Range of the gray house spider in the United States
They create a dome-shaped web that is strung between bushes, on roads, and the edge of woods, usually at head level. They eat flying insects or any insect that gets caught in their sticky web. They detect vibrations, helping them identify when something is ensnared. It’s not uncommon for them to bounce in their web, creating a blurring effect, making it harder to see them. Six spotted orbweavers are as their name suggests with six distinct spots on their abdomens.
Half-Edged Wall Jumping Spider
Depending on the species, the abdominal marking on the black spider’s underside can be pinkish, orange, or deep red. 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. The gray wall jumping spider is a flattened spider with short gray to white-colored hairs. Northern yellow sac spiders are tan or pale green with dark brown.

They are often spotted near public lights that attract flies and mosquitoes, creating an ideal hunting ground for these arachnids. Females, distinguished by their larger size, are known for their web-building skills, while males tend to be found nearby, exhibiting territorial behaviors. Harvestmen is a large order of spider-like arachnoids with thousands of species in the order. Harvestmen are typically small brown creatures with long, delicate arching legs.
False tarantula (Calisoga longitarsus)
Much like their outdoor relatives that eat crop pests, house spiders just want to quietly kill the insects that do covet our food. A black widow is most likely to bite after laying eggs and guarding their egg sacs, but only when disturbed. 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. Many people mistakenly believe that long-bodied cellar spiders have venom that would be lethal to humans. However, their venom is not potent and they have no ability to pierce human skin with their jaws, making these spiders harmless pest-eaters.
An adult female Western Black Widow is shiny and black with an orange or red hourglass shape on the abdomen. If you have noticed dirty cobwebs in the corners of your walls, they could have been left by a common house spider. These dust-covered cobwebs can easily be vacuumed up or swept down without fear of coming in contact with a spider. Common house spiders choose web locations at random and will readily abandon their web to build one elsewhere if their chosen spot does not result in a meal. The Carolina wolf spider is the largest type of wolf spider in California. The large female fuzzy spider has a hairy, dark brown body with a distinctive pattern of tan stripe on its cephalothorax.
Interaction with Other Species
However, it’s crucial to remember that attempting to eradicate them completely can disrupt the ecological balance and may lead to an increase in pest populations. The Grey Huntsman (Isopeda villosa), native to Australia, stands out as an arachnid with its distinct gray base color. This species exhibits a nearly uniform gray hue across both its body and legs, showcasing variations in shades from light to darker grays. Notably, a couple of black spots adorn the area just behind the head, adding to the unique features of these spiders.
California Ebony Tarantula (Aphonopelma eutylenum)
Though they are venomous, their bites are rare and generally only cause localised pain and swelling. Some people can also develop anaphylaxis as the result of a spider bite. We also cover spider bites in our general and childcare first aid courses. We have training locations in every state, capital city, and major town throughout Australia. Continue reading for more information on the Grey house spider, where you are likely to encounter them, and what to expect if you are bitten by one.
They are most active as the sun goes down, which is when they emerge from their sacs and hunt for food, including other spiders. A female Yellow Sac Spider can produce up to five egg sacs after mating. Much like Brown Recluse spiders, which, despite popular belief, do not reside in California, Desert Recluses have a violin-shaped pattern on their backs. Their bodies tend to be about a half inch long, and their leg span can be up to two inches. They live up to three years, and their diet consists of small insects. A male and female often share the same web for long periods, and several females often build their webs in close proximity.
Spiders do not react as strongly to chemical treatments as insects unless they come into direct contact with the spray. Aim to remove spiders, egg sacs, and webs from your house to reduce numbers long-term by using a vacuum, broom, or spider brush with an extendable handle. Although the spider can bite, its venom is not considered dangerous to humans. This invasive species resembles the related false black widow (Steatoda grossa). However, it is larger, and the spider has more white dots on its black abdomen.
During the day, these spiders seek refuge in shaded areas, employing their natural camouflage to remain inconspicuous. This behavioral adaptation aids in both hunting and protection from potential predators. The Gray Wall Jumping Spider’s ability to thrive in diverse surroundings, coupled with its outstanding features, makes it a noteworthy inhabitant of our surroundings. Unlike some spiders that live communally, young Grey House Spiders prefer a solitary lifestyle, eventually venturing out on their own. Usually, noticing a hobo spider in the home causes panic because there are incredibly agile, swift-moving spiders.
