Do Spiders Stay Away From Walnuts

Spiders do stay away from walnuts, and there’s actually some real science and old-school wisdom behind this combo.
 
If you’ve been wondering whether spiders stay away from walnuts, the short answer is yes, they tend to avoid them, especially when walnuts are used in certain forms around your home.
 
This isn’t just an old wives’ tale, either, because walnuts contain compounds that spiders genuinely dislike.
 
In this post, we’ll look at why spiders stay away from walnuts, how you can use walnuts to keep spiders away, and what to expect from this natural repellent.
 
Let’s dig in.
 

Why Spiders Stay Away From Walnuts

Spiders stay away from walnuts for a few solid reasons, and once you understand them, you’ll see why this remedy has stuck around for so long.
 

1. Walnuts Contain Juglone

The biggest reason spiders stay away from walnuts is a natural compound called juglone.
 
Juglone is found in black walnuts especially, and it’s known for being toxic to many insects and pests.
 
Spiders pick up on this compound and tend to steer clear of areas where walnuts are present.
 
This is why you’ll often hear people say spiders stay away from walnuts without even realizing the chemical reason behind it.
 

2. The Strong Scent Overwhelms Them

Walnuts, particularly the leaves and husks, give off a strong, earthy scent.
 
Spiders rely heavily on their sense of touch and smell to navigate, and that powerful walnut aroma disrupts them.
 
Many folks who use walnuts to keep spiders away notice that the smell alone seems to do the trick.
 
So when you scatter walnut pieces or place walnut leaves around, spiders stay away from walnuts and the areas nearby.
 

3. Walnuts Disrupt Spider Habitats

Spiders love quiet, undisturbed corners where they can spin webs and wait for prey.
 
When you introduce walnuts into those spaces, you’re basically making the area less hospitable.
 
The oils and compounds in walnuts can linger on surfaces, and that’s enough to make spiders stay away from walnuts and the spots you’ve treated.
 
It’s a simple barrier method that works surprisingly well.
 

4. Natural Oils Act as a Deterrent

Walnut oil, extracted from the nuts, carries many of the same repellent properties.
 
You can dab a little walnut oil on cotton balls and place them in corners where spiders like to hang out.
 
This is one of the easiest ways to make spiders stay away from walnuts, since the oil concentrates the scent and compounds.
 
Just refresh the cotton balls every week or so to keep the effect strong.
 

How to Use Walnuts to Keep Spiders Away

Now that you know why spiders stay away from walnuts, here’s how to actually put this to work in your home.
 

1. Scatter Walnut Leaves and Husks

If you have access to a black walnut tree, grab some leaves and husks.
 
Place them in corners, near doorways, and along windowsills where spiders tend to enter.
 
This is one of the oldest tricks for making spiders stay away from walnuts, and it costs you nothing.
 
Replace them every couple of weeks as they dry out and lose potency.
 

2. Make a Walnut Spray

You can boil walnut leaves or husks in water, let the liquid cool, and pour it into a spray bottle.
 
Spritz this around baseboards, window frames, and other entry points.
 
This spray is a handy way to make spiders stay away from walnuts because the liquid carries the same repellent compounds.
 
Reapply every few days for the best results.
 

3. Use Walnut Oil on Cotton Balls

Soak a few cotton balls in walnut oil and tuck them into closets, cabinets, and corners.
 
The slow release of the oil keeps spiders stay away from walnuts for longer stretches.
 
Just be careful not to stain fabrics, since walnut oil can leave marks.
 

4. Place Cracked Walnuts in Problem Areas

Cracked walnut shells still carry that strong scent and the juglone compound.
 
Toss a handful into spots where you’ve seen spiders, like garages, basements, or sheds.
 
This won’t kill spiders, but it does encourage spiders stay away from walnuts and the surrounding space.
 

Do Spiders Stay Away From Walnuts All the Time?

Spiders stay away from walnuts most of the time, but there are a few caveats worth knowing.
 

1. Effectiveness Varies by Spider Species

Some spiders are more sensitive to juglone and walnut scent than others.
 
Common house spiders and cellar spiders seem to react strongly, while a few outdoor species might ignore it.
 
Still, for most household spiders, the answer to do spiders stay away from walnuts is a firm yes.
 

2. Freshness Matters

Old, dried-out walnuts lose their potency over time.
 
If you want spiders stay away from walnuts, you need to use fresh leaves, husks, or oil.
 
Replace your walnut repellents regularly to keep the effect going.
 

3. It’s a Repellent, Not a Killer

Walnuts won’t wipe out a spider infestation on their own.
 
They’re best used as part of a broader pest control routine, alongside sealing cracks and reducing other bugs that spiders feed on.
 
But as a natural deterrent, walnuts do make spiders stay away from walnuts and the areas you treat.
 

So, Do Spiders Stay Away From Walnuts?
