How To Get Rid Of Spiders (A Quick Guide)

Trying to keep spiders out of your home can seem like a daunting task. After all, they can come into your home from so many places, and they seem to hide in every corner.

To get rid of spiders, you first have to reduce the number of harborage areas where they can build their webs. Then, it's vital to seal them out along with other crawling pests. Last, it's essential to provide chemical barriers as well.

How To Identify Spiders 

It's challenging to tell poisonous spiders from harmless ones. That's because they all look a bit scary. However, we will try to demystify the different types of species for you here. 

Common House Spider 

The most widely distributed spider species worldwide is the common house spider. The female measures from five to eight millimeters (0.2 to 0.3 inches) in length. However, the males are about half that size.

The body is a distinct caramel color with black spots throughout. Its legs are longer than its body and have yellow and brown rings. 

Common house spiders are not poisonous to humans. However, there have been a handful of minor allergic reactions reported in the last 100 years. 

Wolf Spider

The wolf spider is another household spider that enters indoor spaces in early fall. It does this to escape the cold. Also, there are more plentiful food sources indoors during the winter months.

Wolf spiders don't spin webs. Instead, they prefer to hunt for their prey. They will eat just about anything, including other spiders. However, they are harmless to humans. 

You can identify wolf spiders by their distinctive brown and black patterns. They are often confused with the brown recluse. However, the wolf spider is missing the violin pattern that recluse spiders have behind their heads. 

Hobo Spider

Hobo spiders build funnel-shaped webs and wait at the end for prey to stumble into them. Although they prefer to be isolated, they sometimes build their nests around human habitation. 

Hobo spiders are mostly brown and are 7-14 millimeters (0.28–0.55 inches) in length. There are several black, V-shaped patterns running down their midsections that point to their heads. Also, they have a light stripe running down the middle of their sternums. 

Some hobo spider bites have been reported as causing necrosis. However, those claims have since been disproven. Scientists still believe that hobo spiders are completely harmless to humans. 

Brown Recluse Spider

There are several species of venomous recluse spiders worldwide. The most common one throughout the U.S. is the brown recluse spider. However, its distribution is mainly in the southern states. 

The brown recluse is typically 6–20 millimeters (0.24–0.79 inches) in length. However, they can get much longer. 

The brown recluse is primarily brown, with a distinctive violin shape behind its head. Its bite is dangerous but usually not life-threatening. However, treatment of antibiotics should be given by a doctor to minimize damage to the skin.

Black Widow Spider

The black widow spider is probably the most recognized species in the U.S. The female is entirely black with a red hourglass on the abdomen. However, some types of widow spiders may be brown or even red.

The length can vary between species. Females are around 12 millimeters (.47 inches) long. However, the male is about half that size. Also, males don't have the hourglass marking. 

The black widow spider venom is extremely dangerous to humans. It attacks the autonomic nervous system and causes severe pain or sometimes paralysis. Treatment ranges from a simple analgesic to administering antivenom through injection.

Signs & Causes of Spider Infestation 

You'll probably see the common house spider on your property more than any other species. They prefer to infest woodpiles and other damp areas such as garages and basements, and they build messy cobwebs to trap their prey. 

Less noticeable is the wolf spider. That's because it prefers to hunt at night and doesn't spin webs. Still, for larger infestations, you may observe a few running around during the day.

The brown recluse spider prefers to nest in storage spaces that have plenty of places to hide. For that reason, cleaning these areas will go a long way to reducing their numbers. 

The black widow is unmistakable since it builds sizable, disorganized webs to trap its prey. Look for large, white egg sacs that are smooth. In contrast, the brown widow spider will have bumpy egg sacs. 

One of the biggest causes of spider infestations is the availability of food. For example, if you have lots of flies around your home, you'll probably see plenty of spiders as well. 

Spiders enter homes through cracks in foundations, pipe entry points, and other open areas. You can also unknowingly carry them in from outside.

How To Get Rid Of Spiders

There are several treatment methods for eliminating spiders from your home. However, it's not all about spraying pesticides everywhere. Instead, it's best to use a holistic approach when tackling this tenacious pest. 

Web Knockdowns

Simply knocking down spider webs with a broom will go a long way to eliminating spiders from your home. However, if that doesn't seem very appealing, try using one with an extended pole. Also, consider utilizing an expandable ceiling fan duster or car wash brush.

Spider Sprays

Knockdown aerosols work well to kill live spiders. They also play a role in eliminating eggs and newly hatched spiderlings. 

The best ones contain pyrethrin. This is a pesticide formulated from crushed flower petals. Although made from natural ingredients, it's best not to spray pyrethrins near children or pets. 

Spider Traps

Most spider traps feature a flat piece of cardboard with a layer of glue covering it. The sticky surface faces up. So, once the spider walks over the glue, it gets stuck permanently. 

Other spider traps are a bit more creative. For example, some have a way to enclose the trap to make it more spider-friendly. They also have multiple entrances. This helps catch spiders from all sides. 

Spider traps are also excellent for monitoring pest activity. Once they get stuck on the glue board, they can't go anywhere. This makes it easy to identify the types of spiders you have in your home. 

Residual Insecticide Sprays

Some insecticide sprays are labeled for indoor use. Wettable powders seem to work the best for spiders, and they provide long-lasting protection from a variety of crawling pests as well. 

It's best to use residual sprays in sheds, garages, and storage areas. Although they're labeled for baseboard spraying, we don't recommend it. Instead, spot-treat plumbing areas behind toilets and pipe entry points under sinks where spiders hide. 

Crack and Crevice Treatments

It's good to use earth-based materials for crack and crevice applications. For example, dry insecticides such as diatomaceous earth work well in these spaces. Also, boric acid dust can kill spiders quickly.

It's vital to treat openings around eaves and overhangs. What's more, use dust applications for wall voids, pipe entries, and underneath window sills. 

Natural Remedies for Spiders

Essential oils are excellent for keeping your house free from spiders. They also do a great job of killing them on contact. Here are some of the scents spiders hate the most:

  • Eucalyptus 
  • Peppermint oil
  • Tea tree oil
  • Lemongrass

Try adding a few drops of peppermint oil into a spray bottle. Apply it to areas where you see spiders the most. If you feel it's not strong enough, try using white vinegar, especially to kill live spiders.

How To Prevent Spiders

You can spray all you want. But the easiest way to control siders is to keep them from entering your home in the first place. Here are a few simple ways to do just that: 

Sanitation Measures

Start by knocking down existing webs. You can do this with a broom or vacuuming them with a portable shop vac. Either one works well to eliminate nesting areas.

Next, it's good to declutter areas around your home. Start with:

  • Storage closets
  • Window sills
  • Indoor gardens
  • Pantries
  • Laundry rooms
  • Areas under sinks

The list is almost endless of locations where spiders can hide. However, by decluttering the obvious places first, you give yourself a giant head start. 

As a final note, spiders love cardboard boxes. So, it's best to remove them from your storage spaces and don't let them stack up. This one trick can greatly reduce your home's spider population. 

Mechanical Exclusion Techniques

Spiders can crawl through the tiniest cracks in walls and foundations. However, they are like most pests you find around your home. They tend to take the widest path first.

So, it's best to start with pipe entry points. Seal them off using steel wool or expansion foam. These materials are superior for keeping most crawling pests from traveling through plumbing areas.

Then, it's time to seal foundation cracks with liquid cement. You can also use silicone caulking. However, it may not last as long as other materials. 

Lastly, it's good to caulk around windows and doors. These are also preferred entry spots for spiders. But once sealed, they have to find another way into your home. 

Perimeter Spray Treatments

Using a liquid perimeter treatment to keep out pests makes sense for spiders. It's how professional exterminators keep their customers happy.

It's best to use a formula that will last at least 20 to 30 days. That way, you don't have to spray so often, and it's better for the environment. 

A fan spray of about 20 inches works well between the ground and the foundation wall. You can treat around decks, patios, and garages, as well. Don't forget to spray around doors, windows, and walkways.

Spider Repellents

Another way to repel spiders is with natural spider repellents. There are many pre-packaged formulas to choose from. However, most come in liquid form. 

Many natural repellents are made from peppermint essential oils. You can use them in the garage, basement, or around the perimeter of your home. These products are an eco-friendly way to repel spiders that are safe for children, pets, and the environment.

Spider Control FAQs 

How long does it take to get rid of spiders?

While it's virtually impossible to eliminate every spider in your home, it's certainly possible to manage them. That typically means only seeing one every few months. 

It's important to knock down all the visible webs you can find to gain a high level of control. Next, you have to seal as many entry points as possible, so spiders stay outside. 

Then, it's vital to organize storage areas so that spiders are less likely to construct their webs in these locations. Also, you have a better chance of success if you lay down a chemical barrier outside your home. 

This may sound like a lot of work. But it should only take a few hours to complete the entire process, and the effort will be well worth it long-term. 

What attracts spiders to your house?

The main attractant for spiders is a plentiful supply of insects they can eat. So, the best thing to do is limit those things that attract insects. For example:

  • High humidity. Bringing down the humidity levels in your home will limit insects and the spiders that feed on them. Try using a dehumidifier. Or, invest in a refrigerated air unit for your house. 
  • Open trash containers. Insects love trash, and spiders flock to where there are plenty of insects. For that reason, make sure all trash cans are sealed tight. 
  • Houseplants. Insects feed on several varieties of plant life. The more plants you have in your home, the more spiders there'll be to devour them. 
  • Bright lights. Fluorescent lighting in your home will attract moths and other flying insects. That's why you typically see spider webs near light fixtures. 

What months do spiders come into a house?

The early fall months are when spiders are the most active. However, some species are year-round, depending on where you live. Also, expect to see more spiders in the winter, especially if you have heat in your attic or basement. 

What eats spiders in your house?

Spiders have several known predators. Here is a short list of the most common ones:

  • Birds
  • Lizards
  • Fish
  • Scorpions
  • Centipedes
  • Other spiders

Unfortunately, many of these natural enemies are also considered pests by most people. So, the only option may be to hire a pest exterminator to eliminate your spider problem.
