Does Lavender Oil Get Rid Of Spiders

Lavender oil does get rid of spiders, but only to a certain extent.
 
The truth is that lavender oil can repel spiders and may even kill them on direct contact, but it’s not a guaranteed knockout punch for every eight-legged invader in your home.
 
If you’ve been wondering “does lavender oil get rid of spiders,” you’re in the right place.
 
We’ll break down exactly how lavender oil works against spiders, how to use it, and where its limits lie.
 
Let’s dig in.
 

Does Lavender Oil Get Rid of Spiders?

Yes, lavender oil does get rid of spiders in many situations, and here’s why it works so well.
 

1. Spiders Hate the Smell of Lavender

Spiders are incredibly sensitive to smells, and lavender oil overwhelms their senses.
 
The strong floral scent that we find calming is actually irritating to a spider’s nervous system.
 
That’s why lavender oil works as a natural spider repellent—it drives them away before they ever settle in.
 

2. Linalool and Linalyl Acetate Do the Heavy Lifting

The two main compounds in lavender oil are linalool and linalyl acetate.
 
These compounds are toxic to many insects and arachnids when they’re exposed to concentrated amounts.
 
When a spider comes into contact with undiluted lavender oil, it can disrupt its nervous system and eventually kill it.
 
So yes, lavender oil does get rid of spiders, and in some cases, it kills them too.
 

3. It Disrupts Their Hunting Grounds

Spiders hang around places where other insects live because that’s their food source.
 
Lavender oil repels many of those insects too, which means spiders lose interest in the area.
 
Fewer bugs means fewer spiders, and that’s a win-win for your home.
 

4. It Works as a Barrier Treatment

When you spray lavender oil around entry points like windows, doors, and cracks, it creates a scent barrier.
 
Spiders approaching that barrier usually turn around and look for another way in.
 
That’s the whole point of using lavender oil as a spider repellent—it keeps them from getting comfortable inside.
 

How to Use Lavender Oil to Get Rid of Spiders

Using lavender oil to get rid of spiders is simple, but you need to do it right for it to actually work.
 

1. Make a DIY Lavender Spray

Mix about 10 to 15 drops of pure lavender essential oil with a cup of water in a spray bottle.
 
Add a splash of witch hazel or rubbing alcohol to help the oil mix with the water.
 
Shake it well and spray along baseboards, windowsills, door frames, and corners where spiders like to hide.
 

2. Soak Cotton Balls for Long-Lasting Repellent

Soak cotton balls in undiluted lavender oil and place them in cabinets, closets, and basement corners.
 
The scent lingers for weeks and keeps spiders from coming back to those spots.
 
Just refresh the cotton balls every couple of weeks to keep the repellent effect strong.
 

3. Spray Directly on Spiders You See

If you spot a spider, a direct spray of diluted lavender oil can stop it in its tracks.
 
It won’t always kill instantly, but it will slow the spider down and eventually do the job.
 

4. Combine With Other Essential Oils

Lavender oil works even better when you pair it with peppermint, eucalyptus, or tea tree oil.
 
Spiders dislike all of these, so a blend makes your repellent spray much more effective.
 

5. Clean With Lavender-Scented Products

Wiping down surfaces with a lavender-based cleaner leaves a subtle scent trail that spiders avoid.
 
It’s a low-effort way to keep lavender oil working for you every single day.
 

Limitations of Lavender Oil for Spiders

Lavender oil does get rid of spiders, but it’s not a miracle cure for a serious infestation.
 

1. It Doesn’t Kill Every Spider Instantly

Some spiders are tougher than others, and a light mist of lavender oil may only annoy them.
 
For larger spiders, you may need a more concentrated application or a different approach entirely.
 

2. It Needs to Be Reapplied

The scent of lavender oil fades over time, so its repellent power weakens.
 
You’ll need to reapply every few days or weekly to keep spiders from wandering back in.
 

3. It Won’t Fix the Root Cause

If your home has lots of cracks, moisture, and other insects, spiders will keep coming no matter how much lavender oil you use.
 
Seal gaps, reduce clutter, and control other pests to make lavender oil more effective long term.
 

4. Keep It Away From Pets

Lavender oil can be toxic to cats and dogs if they ingest it or get it on their skin.
 
Use it carefully in homes with pets, and never spray it directly on them or their bedding.
 

So, Does Lavender Oil Get Rid of Spiders?

Lavender oil does get rid of spiders, and it does so by repelling them with its strong scent and, in many cases, killing them on contact thanks to compounds like linalool.
 
It’s a safe, natural, and pleasant-smelling option compared to harsh chemical sprays.
 
Just remember it works best as part of a broader strategy—seal entry points, keep your home clean, and reapply regularly.
 
If you’ve been asking “does lavender oil get rid of spiders,” the answer is a confident yes.
 
With a good lavender spray and a little consistency, you can keep those eight-legged visitors out of your space for good.
