Spiders can be cute as a Halloween decoration, but they can be a nuisance in your house. Sure, they might eat up some other insects for you, but they can be pretty creepy!
Luckily, there are some simple things that you can do to get spiders out of your house. Sealing cracks in your home, cleaning your house frequently, and using scents like citrus, peppermint and cinnamon around areas where spiders frequent can aid in keeping them away.
If you have an infestation or find a spider, you might have no choice but to eliminate it! Spider prevention keeps spiders out of your house to begin with. Not only is this a more humane option, but it will save you time and energy in the long run. Let’s get to it!
How To Keep Spiders From Coming Into Your House
If you live in a home, the same rules apply. You will just have to do things on a larger scale, and since you are probably closer to nature than you would be if you are living in an apartment, there are more things near your house that attract spiders. Spiders love hanging out in your garden or near your compost pile.
You will need to do more than just shutting the windows and doors. Spiders can be teeny tiny when they are young and then grow to be huge once they get inside your house. Seal up any cracks in the walls and keep the areas under your doors clean.
Keep your vents well-cleaned since spiders can come in and move around through the air conditioning system. You can also look into getting a screen for your front or back doors so that you can leave the door open without bugs coming in.
Seal Spider Entrances
Unless you are farming spiders, they are coming from the outside. If you live in an apartment, they could come in through the windows, your balcony, or the entrance hall. Keeping windows shut or putting up a screen can block spiders from coming in.
You might not have much control over how the entrance to your apartment is set up, but you can at least keep the area in front of your door clean and regularly vacuum your mat.
If you are serious about spider prevention, do your neighbors a favor and keep their area clean as well. You will probably be pretty popular if you do a bit of cleaning for everyone. Just make sure not to move their stuff around without asking.
Move Your Trash To Prevent Spiders
Keeping your trash next to the house is practical because you do not have to walk very far to take it out. From a spider prevention perspective, it is not a good idea. Unlike humans, spiders love bugs, and bugs love trash.
A trash can or the surrounding area gives spiders plenty of space to spin their webs and catch some food without having to do much work. Flies are one of a spider’s favorite foods, and if you have ever taken out the trash, you know that flies just love a dirty trash can.
According to the University of California Agriculture and Natural Resources, you’ll want to specifically keep the areas around your home’s foundation trash and vegetation free.
This could be difficult depending on where your trash gets picked up and how big your backyard is. If this is the case, use trash cans that seal very well and are unlikely to get knocked over when it is windy. If insects cannot smell the trash, they will not come near it.
Set Spider Traps
Okay, this is not a spider prevention tactic, but it is a way to get rid of spiders. However, if you have an infestation, you are going to have to look into setting some traps.
Now, most common house spiders are nocturnal, so this is when you’re likely to see them outside and active around your house.
Even if you can catch a few spiders by stomping on them, there are probably more than you think. Setting spider traps will also give you a good idea of how many spiders could hang out in your house. They also come in handy for areas where you spend little time, like your garage or attic.
There are a lot of options out there, but these Catchmaster spider traps are easy to set up and can go just about anywhere. It is non-toxic and will not bother any of your pets or kids, so you do not have to worry about leaving it out.
If you want to do a project with your kids or be super classic, you can try setting up a spider trap with a glass jar full of water. You will need something that attracts the spider, like a bug, and a suitable location where the jar will not topple over. Spiders are not good swimmers, so once they get caught in the water, they cannot make it out.
Now, the good news is that they won’t be upset with you for trying to trap them. You can learn more about spider intelligence our article: 7 Reasons Why Spiders Won’t Remember You (Or Get Revenge) here!
Turn Off The Lights To Help Keep Spiders Away
Remember when we mentioned flies are one of a spider’s favorite foods? Well, flies love light. Just look at your porch light on a hot summer night and you will see what we are talking about.
Lights offer a great place for spiders to spin a small web, and they will almost always find food there. The simple solution is to turn off the lights. It will also save you some money on your next electric bill.
Of course, you cannot keep all of your lights off all the time. Therefore, it is important to keep your lampshades and lightbulbs well-dusted and check regularly for cobwebs. Double-check lights that are hard for you to reach or ones in rooms you do not use very often.
Keep Your House Clean To Eliminate Spiders
This might seem obvious, but it is the best way to keep spiders and other insects out of your house. Cleaning goes beyond just keeping the floors swept and making your bed. If you want to ward off spiders, you need to get serious about cleanliness.
Dust, sweep, and mop regularly. Spiders love cobwebs and dusty areas, particularly in corners. Reaching those areas can be difficult and seem unnecessary, but it’s the only way to get the job done.
According to University of Kentucky’s College of Agriculture, using a vacuum when you find spider webs will help to get rid of any spider egg sacs as well, which can contain hundreds of young spiders.
The kitchen is another place that attracts insects. Keep all of your food well-sealed in airtight containers. If you have any food out, keep it covered and make sure you wash your fruit.
Pay extra attention to the areas where spiders are most likely to hang out and where you spend the least time. Bugs dislike hanging out in the same areas as people, so they are much more likely to hide in your attic and basement than in your living room.
Keeping your house clean is also a good idea in general. It will help you keep things organized, both physically and mentally. In fact, there is evidence that our disgust toward spiders and dirty things such as mold is connected.

Use Spider Sprays
A classic tool for keeping out spiders and insects is pesticides. A lot of pesticides are full of unhealthy chemicals and can be dangerous to have lying around if you have kids or pets keen on opening things. Thankfully, there are environmentally friendly options that allow you to spray without worrying!

The Best Spider Repellent
Obviously, the best spider repellent is the one that keeps spiders out of your house. There is no single answer about which kind is best since there are different species of spiders and your individual needs might vary. To break it down, there are essentially two types of sprays you can use.
The first type of spray you can use is a spider repellent. These are designed to ward off spiders, like the Mighty Mint Spider Repellent. This repellent uses natural ingredients like peppermint oil to keep spiders and insects away.
Sprays that use peppermint oil or other scents spiders dislike are very effective in keeping spiders away, but they will not necessarily eliminate them if you spot one. If you need to eliminate a spider, you will need a different type of spray.
How To Get Rid Of Spiders Quickly
Spider prevention is great, but when you find a tarantula crawling up your wall, a spider repellent is only going to send the spider scurrying off to another spot in the house. When this happens, you’ll want to get rid of a spider the second you see it.
To instantly eliminate spiders, you will need a stronger spider spray. The Terro Spider and Ant Killer spray will eliminate spiders on contact. If you stumble across a poisonous spider, this is what you should be using.
Eliminating And Keeping Away Spiders
While we are on the topic of eliminating spiders, let’s delve into this deeper. Like we mentioned at the beginning, what we want to do is prevent spiders from coming into your home to begin with. This takes some trial and error, and you might be reading this because you have already spotted a spider and want to know how to get rid of it.
If you run into a dangerous spider or have consistent spider problems, consult an expert about elimination methods. They can give you more personalized advice about keeping spiders out of your home.
Problem spiders often live in dry, hot climates. If you live in the Southwest or an area with a desert-like climate, you are more likely to encounter dangerous spiders than if you live in a cooler climate. Spiders will also wander into your house more during the winter months when it is cold outside.
If you live in an area with a high population of problem spiders, consult a pest expert.
But if you see a spider, you need to know what to do with it at the moment, and maybe you do not have spider spray on hand. The classic methods are using a fly swatter or stomping on it. If you do not have a fly swatter, use a book or a rolled-up magazine or newspaper.
Make sure you use something you don’t mind getting dirty. The spider’s remains might stick to whatever you’ve squashed it with.
If you encounter a poisonous spider, proceed with extreme caution. Bigger spiders like tarantulas and black widows are going to require something heavier to eliminate them.
Once you have successfully eliminated the spider, there are several ways to get rid of it. One option is flushing it down the toilet or a drain. Leave your worry at the door because a spider will not clog your plumbing system.
You can also simply throw the spider’s remains in the trash, dump them outside, or in your compost pile. If you plan to let the spider decompose, take it as far away from your front door as possible, especially if it is a bigger spider. Leaving the spider’s remains near your house is only going to attract ants and other pests.
Now that we have gone over what you should do when you need to eliminate a spider, let’s get back to spider prevention!

Use Ultrasonic Technology To Deter Spiders
This idea might seem strange, but if you think about it, it makes perfect sense. Insects sense sounds and waves and higher frequencies than humans do. Noises that bother us might not even bother insects and vice versa.
When you think about a spider’s biology, it makes perfect sense. While spiders lack long distance hearing, their ears are quite sensitive and pick up a great deal of close noise.
A spider’s biological needs differ from a human’s needs, and its anatomy reflects that. A spider has to be on alert for its natural predators and more aware of its environmental surroundings than we do. Spiders’ brains are less developed than ours, and as soon as they perceive a threat, they will take off running.
Ultrasonic sounds are within a spider’s hearing range and will trigger their survival instinct. These sounds are emitted outside of our range of audible frequencies, but they may affect your pets.
Modern technology allows you to put this into practice in your own home. The Brison Ultrasonic Pest Repeller plugs into your wall and emits ultrasonic sounds that will ward off spiders and other pests. I’m not the overall biggest fan of ultrasonic repellents as they can be hit or miss, but they’re worth the shot as all it’s emitting is a noise.
You can read more about the science of ultrasonic pest repellers here.
Strong Scents Repel Spiders
Hearing is not the only sense that differs between humans and spiders. Spiders are very sensitive to particular smells. Many of these scents are ones that humans find enjoyable, which is great news for us!
Spiders are particularly sensitive to peppermint and cinnamon. In fact, most natural pesticides will use essential oils to ward off pests. Using the essential oils on your own lets you create your perfect mixture so your house smells exactly the way you want it.
The best way to use essential oils to ward off spiders is with an essential oil diffuser. There are a lot of options out there, and something like the Everlasting Comfort Essential Oil Diffuser has a very natural aesthetic and is effective. It is easy to move around, so if you find you have problems with spiders in different areas, you can pick it up and put it somewhere else as needed.
Even if you still have problems with spiders after setting it up, an essential oil diffuser brightens up your home!

Chestnuts Can Drive Spiders Away
This idea is more of an old wives’ tale, but it is pretty easy to test and low-cost, so why not try it? Conventional wisdom says spiders dislike the smell of horse chestnuts and they will ward them off.
Simply gather some horse chestnuts or, if you do not live in a place where you find them in the wild, buy some at the store. They usually go on sale during autumn and shortly before Christmas. Then, take a few and scatter them around your house in places where spiders like to hang out.
It should not take many chestnuts to do this effectively, so roast the others and enjoy them! If you do not want to leave chestnuts just lying around your house or worry about a pet snapping them up, try putting them in a potpourri bowl as a decoration.
Even if it is just a myth that chestnuts ward off spiders, it is a great way to decorate your house and bring in a bit of fall spirit!
Citrus Is A Spider Repellent
If you do not want to invest in an essential oil diffuser, or you want to create a romantic atmosphere in your house, try burning some citrus candles or using citrus-scented aroma sticks. Spiders will avoid all types of citrus, so it does not matter if you go for lemon or orange or another citrus scent of your choice.
Most household cleaners use at least some citrus since it is also an effective cleaning ingredient. If you make your own cleaner, you can throw some lemon peels or lemon juice into the bottle.
Citrus has more benefits than warding off spiders. It will also keep other pests from coming in. Other insects also dislike citrus, and rats and mice are not huge fans either.
It will also keep your house smelling fresh. At some point, you will probably have some extra lemons lying around that you will need to use. Citrus is one of the cheapest, eco-friendly pesticides out there.
Consult A Professional
The tips we have given are good places to start, but they are not a guarantee. Every home is different, so there is no way to find a one size fits all solution to spider prevention. A good rule to keep in mind is that the more precautions you take, the higher your chances are of keeping out spiders.
However, even that is not a guarantee. For the best results, you will need to talk to a professional pest control company. They can give you advice tailored to your individual needs and your house.
Consulting a professional team is also a great idea if you are going to be out of town for a while and do not want bugs creeping up when you are gone. It is also a great way to support local businesses.

That’s All For Now!
If you made it this far, you have probably figured out by now that there are many methods of spider prevention. None of them are going to be 100% effective, so it is best to try as many of these tips as possible. Considering they are all low cost and some of them, like aromatherapy, even have other health benefits, there is no reason not to give it a go!
To sum up, keep your focus centered on spider prevention, not elimination. This will save you time and energy and probably help you sleep a lot better. Seeing a spider near your bed may just keep you up at night.
Preventing spiders from coming into your house will also help keep out other pests and make your house an all-around pleasant place to live. In the meantime, thanks for reading, and good luck keeping your home free of spiders!
