Want to know how to keep spiders away without killing them? Spiders inside the home are not a welcome prospect for most of us. Out in the yard, they’re beneficial, so it’s great to have them in the garden, but while they can provide pest control inside the house and are mostly harmless, we’d still rather not share. 

But how to put them off taking up residence in your interiors? We asked the H&G team to share their tried-and-tested, favorite, and failsafe ways to keep spiders away.

10 ways to keep spiders away

Think prevention in the first place, then removal of the spiders that have made it inside to avoid unwanted residents. Just like getting rid of fruit flies, some of these tips are more about prevention than cure. This is how to keep spiders away. 

1. Fill gaps and cracks

Any gaps and cracks around doors and windows give spiders an easy route into your home, so fill these using caulk or weather stripping. 

‘I make an inspection of the outside of my home at the end of every summer,’ says Jennifer Ebert, digital editor. ‘I know that as soon as temperatures drop in fall, I’m more likely to find spiders inside, so this is a way of minimizing their opportunities.’

2. Turn off lights at night

Like to light up the outside of your home at night? You’re attracting spiders, albeit indirectly. The lights bring insects, and the insects bring the spiders that prey on them. 

‘I make a habit of keeping outside lights off as much as possible,’ says Lucy Searle, global editor in chief. ‘Fewer bugs has definitely cut the number of spiders I’ve seen inside, and while I love looking out at the yard at night, I'm aware that it's not energy-efficient to do so, so it's a win-win.’

3. Keep up with pruning

While it’s great to have a wildlife garden including spiders, don’t encourage them to make their home right beside your house. That means avoiding locating bushes and other vegetation by the walls and growing plants up them. 

‘Spiders are an asset in the backyard, so do allow them to thrive while taking measures to keep them out of the house,’ says Teresa Conway, gardening writer. ‘Piles of logs, twigs and so on away from the house will provide them with the situations they favor in the yard.’

4. Clean regularly

Spiders are, of course, not the only reason why you should clean regularly, but keeping them away is one of the reasons to do so. Dust and vacuum, getting into corners and crevices, and tidy and declutter and they are less likely to find an undisturbed spot in which to take up residence.

‘Don’t neglect the basement and garage when it comes to periodic cleaning and decluttering if you want to keep spiders out of the house,’ cautions executive editor Kaitlin Madden.

5. Focus on houseplants

Spiders don’t live on houseplants, but they might hide there, so take a look – and take any outside.

Be aware, too, that spider mites – which are also arachnids and also have eight legs – could be eating indoor greenery. 

‘There are miticides for controlling spider mites, but most are not for indoor use,’ says Marisa Y Thompson, PhD, extension horticulture specialist in the department of extension plant sciences at the New Mexico State University Los Lunas Agricultural Science Center (opens in new tab). ‘It is easier to just put the houseplant in the bathtub or shower and spray with a strong, but fine mist of water.’

6. Repel them with citrus

It’s said you can put spiders off the natural way with a citrus-containing spray. To create your own, mix around 20 drops of lemon or an alternative with water and spray on windowsills or in corners.

‘I have tried this,’ says houses editor Karen Darlow. ‘It wasn’t a scientific experiment, but I think it made for fewer spider sightings last fall, and it definitely smelled good.’

Recommended alternatives are sprays made up in the same way using essential oils such as cinnamon, peppermint, lavender or tea tree.

7. Store securely

That box of holiday decorations could be providing spiders with a home in your home. ‘Store seldom-used items like this in boxes with secure lids,’ says style editor Emma Thomas. ‘This way you won’t be providing spiders with an undisturbed hiding place. It will keep your ornaments in top condition, too.’ 

8. Move the woodpile

Yes, keeping firewood stacked by your house is convenient, but it’s also convenient for spiders and from there it’s not far to the inside of your home.

‘I can say we’ve seen fewer spiders inside since we moved our woodpile to a different location further away from the house,’ says Melanie Griffiths, Period Living editor.

9. Show them the door (part 1)

Like any uninvited guest, once spiders have found their way inside, it’s important to make it clear that they shouldn’t think of setting up home. The easiest way to do this is to take them outside using a glass and a piece of cardboard. 

Invert the glass over the critter, slide the cardboard underneath and trap it, then walk it to the end of the yard for release. 

‘Be safety conscious,’ says gardens editor Rachel Crow. ‘There are venomous spider species in the US, including the black widow and the brown recluse. They are more likely to be encountered outside but take a look on the CDC (opens in new tab) site so you know what they look like, and check UC Riverside’s map (opens in new tab) to see the range of the brown recluse.’

10. Show them the door (part 2)

If picking up a spider in a glass is a little too much close contact for you, try a bug grabber instead. We like the My Critter catcher (opens in new tab) from Amazon, which allows you to stay at a comfortable distance from the intruder.

‘Arachnophobe who nevertheless doesn’t want to harm spiders?’ says shopping editor Annie Collyer. ‘A bug grabber will rid your of your problem without weighing on your conscience.’

What smells keep spiders away?

A host of smells are reputed to keep spiders away. They include citrus, mint, lemongrass and eucalyptus. But be aware that spider experts aren’t convinced. Our opinion? Since these will all make your house smell good, it’s worth giving them a try.

Can you spider proof a house?

You can make a house more spider proof, although be aware that a spider can fit through the tiniest of gaps. To cut down their opportunities to come insider use caulk around windows and door edges and door sweeps to outside doors. Fix damaged window and door screens, too.

Grow trees and shrubs away from the outside walls of your home, and don’t stack firewood or flowerpots beside it either.
