Boise, Idaho, is home to 12 unique spider species. It is likely that one of these species might be crawling around in your home, somewhere in the dark corners. No matter what the species it might be, these eight-legged crawlers are never a welcomed guest.

Since Averse Pest Control is one of the top spider control companies in Boise, we know what type of spiders you can encounter. Spiders usually invade your indoor living space during a colder month, and as we all know that winter has approached and is now peaking, your home or business place is always at a risk of infestation.

So, here are some of the commonly found spiders in Boise, Idaho.

Wolf Spider

These are the scariest spiders in Idaho. Like other spiders, Wolf Spiders are hunters. They don’t set traps or other trickery and can grow up to an inch in length. They usually chase and tackle their prey and kill them with their venomous bite. Their attribute of being hunters make them dangerous for human beings as well. If threatened or disturbed, they are likely to jump on you and bite you. Wolf spiders invade homes during summer and fall months and are attracted to dark and damp environments. Though these spiders aren’t a significant threat to humans, still you should be careful if you see them in your house.

Hobo Spider

Hobo spider, also known as the aggressive spider, is widespread in the state of Idaho. These spiders are usually ¼, and ½ inch in size, and are found lurking around the ground level. They create funnel-shaped webs and feed on other insects in your house. Hobo spiders can bite human beings when they get into their clothing or bedding and pressed against the skin. Usually, Hobo spiders don’t inject venom into your body. If they do so, the bite area will become hard, followed by blisters. These blisters break down after 24 hours, and a slow-healing wound is left. However, in some rare cases, the bite can result in tissue damage, which requires medical attention.

Crab Spider

These spiders are mostly found in your backyard, sitting on flowers and other places where insects land. Their fronts legs are pretty long and stretched out, waiting for their prey. Crab spiders can also change their body color, which makes it difficult for their prey to see their presence. They are harmless to human beings and are smaller than the size of a raisin.

Jumping Spider

Ever spotted any bright colored spiders in your home? Yes, these are the jumping spiders. You’ll mostly encounter them in your garden, and are often sitting on walls or fences. One interesting fact about these spiders is that they can walk in any directed regardless of where they are facing. They can also leap long distances onto unsuspecting prey. Jumping spiders can grow between ¼ and ¾ inches and aren’t dangerous to humans.

House Spider

These are common house spiders, having a combo-foot with a hunting style nature. They are usually found in your garage, sheds, barns, woodpiles, and under eaves. House spiders grow up to an inch in length and don’t pose any danger to human beings. However, their infestation is a big nuisance and should be treated immediately.

Brown Recluse

Though not found in Idaho, still, they can be transported to your home or business location via your luggage, clothes, the trunk of your car, etc. These are highly poisonous spiders, and they grow to the size of a quarter, including the legs. If they bite you, it is painless at first, but you will develop an ulcer that gradually destroys the soft tissue and eats away your skin. However, in some cases, their bites can have severe symptoms and are usually fatal.

Black Widow

Black Widows are considered the most venomous spiders in Idaho, and they are found commonly here. They weave cobwebs to entangle their prey and use their combed foot to tear apart in pieces. They usually make their homes in garages, woodpiles, and barns. Black widows rarely nest in living areas, but they have been found hiding behind furniture, which is seldom moved. Male black widows are much smaller, whereas the females grow up to 1 ½ inch in length.

Despite being venomous, they usually don’t pose any risk to human beings unless threatened or disturbed. If bitten by one, the pain is similar to a bee sting. However, this bite can turn into intense pain with a matter of minutes. Their venom gradually spreads throughout the body and results in cramping, partial paralysis, nausea, headache, fever, and breathing problem

Cat-Face Spiders

These spiders have very unusually shaped bodies, thus named cat-face spiders. They create beautiful concentric circular webs and are commonly found in gardens and outdoor areas of your house. Whenever a prey gets trapped in their web, they quickly capture them in silk and carry to the center of their web to geed on it.

These spiders do not pose any danger to humans and can grow to the size of a half-dollar. However, they reproduce very fast, which makes them a nuisance. If ignored, they’ll spread throughout your living space, and you will see dead carcasses here and there in and around your house.
