How to Get Rid of Spiders in Your House

This guide is everything you need as a homeowner to keep your home spider-free forever. You will never worry about spiders

Here’s what you need to know about spiders in your home, including where they can hide. We’ll also tell you about an underrated alternative to spider spray that few homeowners know about. Spiders will stay away from you longer with it than anything else.

Basics of Spiders

Spiders do not belong to the insect family. The family of these insects is called arachnids, along with ticks, Spider mites, and scorpions. 

Although spiders have an exoskeleton, they are also invertebrates. The skeletons of these animals are outside their bodies. A spider’s internal skeleton, called an endoskeleton, is also notable.

The body of an insect consists of three parts – the head, the thorax, and the abdomen. Also, insects have two eyes, six legs, antennae, and if they have wings, four wings.

On the other hand, spiders have more than two eyes, eight legs, and two body parts. The brown recluse spider is the only spider with six eyes.

There is no separate thorax in spiders. They have a combined thorax and head, and this is called a prosoma or cephalothorax.

Antennae and wings are not found on spiders.

Spiders that sneak into your home can be divided into two categories: spiders that hunt and spiders that spin webs. 

To catch their prey, spiders spin webs in calm, difficult-to-reach places. 

The spiders wait to catch prey inside the web until it walks in or flies into it. A spider that spins a web has poor vision. In order to reach prey stuck in the web, they use vibrations. 

Adaptable and resilient, web-spinning spiders are capable of living both indoors and outdoors. Hunting spiders, on the other hand, do not make webs to capture their prey or to catch their prey. 

The prey of some hunting spiders is actively sought after by the spiders. Other spiders wait for prey to approach to capture it when it is in close proximity.

Their prey is swift and they pounce on them in order to catch it. 

Hunting spiders can spin a tiny web as a resting place. Those spiders wouldn’t hunt on that web. Spiders that hunt are all outdoor spiders, and they are better suited to live outdoors. 

The hunting spider is an accidental intruder into your home. During the fall, you may find a few of them in your home.

It is impossible for hunting spiders to survive indoors for long. They try to leave as soon as possible if they are indoors. They cannot also reproduce indoors. 

Web-spinning spiders in the United State.

Comb-footed spiders

Spiders of this species grow up to 0.4 inches in length, and they’re brown or gray. 

They have a more prominent abdomen than their heads. Because of this, comb-footed spiders don’t become very active. 

The spiders spin webs in woods and rock piles outdoors. These spiders are typically found in quiet areas like basements and storage rooms.

Their webs are not designed or patterned in any way.

The American House Spider

This spider is the most common one found in American homes. Its abdomen is marked with a grayish or brownish color. There is a diameter of 0.25 inches.

Webs are loose, and it weaves them in quiet areas of the house like most indoor spiders.

Cellar Spiders

US homes are also infested with cellar spiders, which measure up to 0.25 inches in length.

These spiders can be found in places such as basements and attics, as their name suggests. These spiders can also be found in basements, garages, and crawl spaces. 

In high places, such as ceilings, these spiders can also make webs. 

Gray in color and sometimes tan, cellar spiders have long, thin legs that look fragile. 

Orb Weaver Spider

The orb-weaver spider is an outdoor spider, and entomologists classify it as a garden spider. 

Yard and garden spiders such as these are quite common. Indoor spiders are rare. 

These spiders grow up to an inch long and can be found in a variety of bright colors.

In concentric circles, they spin their webs between tall grasses. Their webs are radiance-filled, giving them an attractive appearance.

In addition to having a swollen abdomen, an orb-weaver spider has an off-shaped shape as well.

Orb-weaver spiders aren’t dangerous despite their bright colors.

You can find four types of orb-weaver spiders in the United States.

These four types are Barn spiders, Marbled Orb Weaver Spiders (the most beautiful and colorful orb weaver spiders), Argiope Spiders (with yellow and black spots on their abdomens), and Banded Argiope Spiders (with yellow and black stripes on their abdomens).

Spiders that weave orbs on the ground are horrendous. If they fall from their web, they cannot move well. The orb weaver spider has the weakest eyesight of all spider species. 

Humans are not at risk from them. In case you happen to see them in your backyard or garden, it’s best to leave them alone.

Funnel Weaver Spiders

With an average length of 0.75 inches, funnel weaver spiders are of medium size. Their heads have distinct stripes that make them appear brownish or gray. 

There would also be a pattern of stripes or spots on the abdomen. The funnel weaver can live both indoors and outdoors, just like the orb weaver. 

You would find them resting on their web in low shrubs and bushes outdoors. Webs are spun indoors near the ground, around steps, foundation, and sometimes under furniture.

Weavers of tunnels weave their webs horizontally, flat, and tunnel-like. Weavers of tunnels use their webs to hunt and rest.

Funnel weaver spiders can be divided into two types in the US – barn funnel weavers and grass weavers. There would be a couple of dark stripes on the barn funnel weavers’ heads. 

It is possible for barn funnel weavers to hide inside drawers, closets, and wardrobes.

An outdoor grass spider is a spider that constructs funnel-shaped webs in short grasses on lawns and gardens. 

Three light-colored and two dark-colored stripes appear behind the head of grass spiders.

Black Widow Spiders

The black widow spider, despite numerous instances of them creeping into homes, is actually an outdoor spider.

In the US, black widow spiders are everywhere. Spiders known as black widows have a red hourglass-shaped mark on their abdomens. 

Some black widow spiders, however, can only possess red spots instead of an hourglass-shaped mark. 

Spiders that make black widow webs build them near the ground. Instead of flies, they build their webs to trap crawlers. 

There are places in your home that are hard to reach and don’t receive a lot of light where you’ll find black widow spiders.

A black widow spider lives outdoors in woodpiles, organic debris, loose wood bark, and underneath stones.

It is possible for a black widow spider to reach a length of 0.4 inches. Black widow spiders leave egg sacs and spider webs as their two major signs of infestation. 

Hunting spiders in the US. don’t spin webs

These spiders are rarely found inside your home. They may, however, manage to find their way in.

Wolf Spiders

Wolf spiders can reach a length of an inch. They have bristles on their body that are dark brown. 

The creatures hide under rocks, bushes, beaches, landscapes, gardens, and yards, as well as in agricultural fields. Warm weather is their favorite time to hunt, and daytime is when they do best. 

It is rare for wolf spiders to hunt at night, and they do so only if the nights are warm. Wolf spiders crawl fast, look frightening, but are not aggressive towards humans.

Yellow Sac Spiders

Spiders with yellow sacs are medium-sized spiders with a diameter of 0.4 inches. Yellow is the color they are named after. 

The abdomen of some yellow sac spiders may have a black spot. The yellow sac spider hunts small insects at night. 

A spider doesn’t spin a web. Sac spiders roll leaves into tubes or construct a sac beneath stones to make a hiding place.

In case they ever enter a building or a home, they will move to high places near the ceilings.

Fishing Spiders

A fishing spider can be found near swamps, ponds, lakes, rivers, and streams. Fishing spiders inhabit damp areas and can reach a length of one inch. 

Their legs are thick and strong. The legs span nearly four inches, and they can cover a lot of ground. An abdomen that is dark, usually black, with visible white markings. 

To catch prey like tadpoles and small fish, fishing spiders can dive into the water. As a boatman, they are also able to glide on the surface of the water. 

Jumping Spiders

The jumping spider is a blackish or dark-colored creature that can reach half an inch in length. 

To hunt their prey, jumping spiders pounce on their prey. They can jump considerably farther than their size would allow. Also, their abdomens, mouths, and legs have a hairy texture. 

Spiders that jump have a wide range of motion. Because of that, they can move both forward and backward at the same time.

Jumping spiders possess the best vision among spiders. The spiders are able to see objects eight inches away. 

Jumping spiders are day spiders, which means they hunt most during the day. If they manage to get into your house, you will find them in areas that receive direct sunlight. 

As a result, you’d see them near windows, on ceilings and walls that receive natural light. In the outdoors, jumping spiders hide in tall grasses, under the loose bark of trees, and under rocks and stones. 

A jumping spider can spin a web, but it is primarily used for keeping its egg sac and resting, not for hunting.

Parson Spider

Like the wolf spider, the parson spider is about half an inch long, with a brownish body and grayish abdomen. The parson spider hunts at night by running down and chasing its prey.

A parson spider hides under stones and loose barks, just like many other hunting spiders. The only place they like to hide is in cracks on walls and floors if they manage to break into your home. 

Also, they can get into drawers and jars that are left open.

Crab Spiders

Spider crabs come in a variety of colors, including yellow, red, and brown. Their length can reach 4 inches. 

Compared to the rear four legs, the front four legs are longer. Spiders are often compared to crabs because of this feature.

Crab spiders are also capable of moving backward, right, or left, just like jumping spiders. The crab spider is a passive hunter. 

In other words, they hide and wait for the prey to come close before pouncing on it. A crab spider would never be found indoors. Crab spiders are usually found outdoors on flowers, branches, and twigs.

Brown Recluse Spider

The brown recluse spider hunts spiders that prefer to live outdoors. However, they can also live indoors if they are strong enough. 

These spiders can be found in attics, basements, garages, and crevices on walls and floors in your home. A brown recluse spider can grow up to half an inch in length as an adult.

Webs are spun by brown recluse spiders. Their web is not as dense as other spiders that spin webs. Spinning the web is primarily about resting rather than hunting.

In order to hunt, brown recluse spiders don’t spin webs. Brown recluse spiders are passive hunters, just like crab spiders. 

How Can You Keep Your Home Spider-Free?

Here is a guide for you!

You have covered a lot of ground up to now. You now understand why spiders enter your home, where they hide, and how to identify them.

You will now learn how to get rid of spiders. Spiders enter your home through cracks and crevices around the house.

If they can get inside your car, spiders can also hide there. Unintentionally, they can enter your home by moving plants, firewood, and cardboard boxes where they may hide.

Therefore, you should seal the gaps and cracks in your home with a silicone-based sealant to prevent intruders from entering.

That way, spiders wouldn’t be able to enter your house easily. Before bringing any outdoor items inside, check for spiders. 

Clutter and dirt inside the home make your home an easy hiding place for spiders. Clear clutter from your home and vacuum often to make your home less attractive to spiders.

While cleaning up clutter in spaces such as attics and basements, wear gloves and shoes. Your skin will be protected from accidental spider bites.

You can trap spiders by placing jars on them when you find them. Under the jar, paper or cardboard should be slid. In this way, the liquid will not leak.

As you lift the jar, be careful not to drop it. Your hand should be pressed against the paper. The spider will not be able to escape the jar that way. 

You must remove the jar from your property, which also means your yard. 

Once the paper is removed from the jar opening, slowly place the jar on the ground. As the spider crawls away, the jar will close.

Keep the spider instead of throwing it away. As spiders are soft, they can die if thrown away. Spider traps based on pheromones can be used if you’re sure there are spiders hiding inside your home. 

Spiders are attracted to these sticky traps because they emit a smell that bugs emit. If you have a storage room at home, make sure you keep boxes off the floor and away from walls. 

Thus, these boxes and storage items will be less likely to harbor spiders. If you do it wearing gloves, you will be protected from spider bites.

Using a vacuum cleaner, you can also remove spider webs. To keep your home free of spiders, get rid of all the insects and bugs inside. 

As a result, spiders become attracted to your home, causing them to sneak inside.

Do Insecticides Kill Spiders?

No, since pesticide sprays aren’t a long-term solution to rid your home of spiders. It’s true that pesticides kill spiders, and you can buy sprays that kill spiders.

However, these pesticide sprays only work if they are sprayed directly on spiders. Spiders will avoid surfaces sprayed with pesticides or aerosol sprays if you spray them.

Spiders are harmless, so you should not kill them with anything other than a rolled-up newspaper or under your boots.

After you remove the spider’s body, disinfect the surface with a disinfectant. In the absence of this, other bugs, such as ants and cockroaches, will be attracted.

Sorptive dust is a better alternative to pesticides and spider sprays.

The absorbent dust contains silica aerogel and pyrethrins. Spiders and insects get stuck on these compounds when they crawl on dust.

If the dust gets stuck on the spider, it will penetrate its body and dry it from inside, killing it. The use of absorbent dust is a better and more permanent solution to spider control than spider sprays. 

Apply it to gaps and cracks in attics, basements, walls, floors, and other difficult-to-reach places. The spiders won’t be able to hide here because it’ll kill them.

When using spider sprays or sorptive dust to kill spiders, please read the product’s instructions before using it.

Remember, spiders are an essential part of our ecosystem. Moreover, they consume bugs and insects to keep your home and garden free of them. 

It is better to trap them and release them far away from your home than to kill them. 

Spider Bites

Is it possible for spiders to bite humans? 

In some cases, they can, but usually not unless you provoke them or if they accidentally get squeezed. 

Humans and pets are unaffected by spiders when left alone, including the giant hunting spiders. The bite of these insects can cause an itchy sensation, redness, and lumps. 

If you are allergic to bug bites, spider bites can also trigger an allergic reaction. In the event that you don’t treat black widow spider bites immediately, they can cause bacterial infection. 

In the United States, there have never been any deaths caused by spider bites.


The spiders you find inside your home are not all friendly. A lot of them don’t even if they accidentally enter. With this guide, you’ve learned what spiders are more likely to hide in your home and where they will hide.

Detailed instructions are also provided for preventing these spiders from entering your home.

Further, in this post, I’ve mentioned sorptive dust as an effective alternative to spider spray and explained why it’s superior.
