You can get rid of ants in your basil plant by addressing both the ants themselves and the root cause that’s attracting them in the first place.
If you’ve spotted ants in your basil plant, you’re likely dealing with more than just a few random visitors.
These tiny pests are usually there because of honeydew, a sweet substance left behind by aphids or other sap-sucking insects.
In this post, I’ll show you how to get rid of ants in your basil plant using simple, natural methods that are safe for your herbs.
We’ll cover why ants are drawn to your basil, the best ways to remove them, and how to keep them from coming back.
Let’s dig into the dirt and get your basil ant-free.
Why Ants Are In Your Basil Plant
Understanding why ants are in your basil plant is the first step to solving the problem.
Ants don’t actually eat the leaves of your basil, so they’re not there for the plant itself.
Instead, ants in your basil plant are almost always a sign of a bigger issue.
The most common culprit is aphids, which are tiny, soft-bodied insects that suck the sap from your basil leaves.
Aphids excrete a sticky, sugary liquid called honeydew, and ants absolutely love this stuff.
So when you see ants in your basil plant, they’re likely farming the aphids to harvest that honeydew.
1. Aphids Are The Real Problem
If you want to get rid of ants in your basil plant, you’ve got to deal with the aphids first.
Ants in your basil plant are protecting the aphids from predators like ladybugs.
They’ll even carry aphids to fresh parts of the plant to keep the honeydew flowing.
So if you spray for ants without addressing aphids, the ants will just keep coming back.
Check the undersides of your basil leaves for clusters of tiny green, black, or white bugs.
Those are aphids, and they’re the reason ants are in your basil plant.
2. Moisture And Shelter Attract Ants
Sometimes ants in your basil plant are just looking for a good home.
Basil needs consistently moist soil, and that damp environment can be appealing to ants.
If you have thick, bushy basil foliage, it also provides excellent shelter for ant colonies.
Ants in your basil plant might be nesting in the soil or just passing through your pot.
Either way, you can make your basil less inviting by keeping things tidy.
How To Get Rid Of Ants In Your Basil Plant Naturally
When you’re ready to get rid of ants in your basil plant, skip the harsh chemicals.
You’re going to eat this herb, so you want methods that are food-safe and eco-friendly.
Here are the most effective natural ways to clear ants from your basil plant.
1. Blast Them Away With Water
A strong spray of water is the quickest way to get rid of ants in your basil plant and dislodge aphids at the same time.
Take your basil outside and use a garden hose with a spray nozzle or a kitchen sink sprayer.
Aim the water at the undersides of the leaves, where aphids and ants like to hide.
The force of the water will knock both pests off your basil plant.
You’ll need to repeat this every few days until you no longer see ants in your basil plant.
2. Use A Dish Soap Spray
A simple solution of water and mild dish soap is a game-changer for ants in your basil plant.
Mix one teaspoon of dish soap with one quart of water in a spray bottle.
Shake it gently, then spray your basil plant thoroughly, covering the stems and both sides of every leaf.
The soap breaks down the ants’ protective outer layer, and it also suffocates the aphids.
Wait about 15 minutes, then rinse the spray off with plain water so the soap doesn’t damage your basil.
Repeat this treatment every few days to get rid of ants in your basil plant completely.
3. Wipe Leaves With A Neem Oil Solution
If dish soap alone isn’t enough, neem oil is a powerful natural insecticide for ants in your basil plant.
Mix one teaspoon of pure neem oil with one quart of warm water and a few drops of dish soap as an emulsifier.
Spray this mixture onto your basil, focusing on the undersides of the leaves.
Neem oil disrupts the life cycle of aphids, so the ants lose their honeydew source.
It also deters ants from returning to your basil plant because of its strong, bitter smell.
Apply neem oil in the evening to avoid leaf burn from the sun.
4. Deter Ants With Diatomaceous Earth
If you want to keep ants out of your basil plant’s soil, food-grade diatomaceous earth is a great barrier.
This fine powder is made from fossilized algae and it’s safe for humans and pets.
Sprinkle a thin layer of diatomaceous earth on the top of the soil around your basil plant.
When ants walk through it, the powder scratches their exoskeleton, causing them to dehydrate.
Just don’t get it on the basil leaves themselves, as it can irritate your mouth if eaten.
Reapply diatomaceous earth after watering, since moisture will reduce its effectiveness.
How To Keep Ants From Coming Back To Your Basil Plant
Getting rid of ants in your basil plant is only half the battle.
Once they’re gone, you need to take steps to keep your basil plant ant-free for good.
Prevention is the best way to avoid dealing with this pest problem again.
1. Inspect And Clean Your Basil Regularly
Make it a habit to check your basil plant for pests every few days.
Look at the leaf undersides, the stem joints, and the soil surface for any insect activity.
Early detection makes it much easier to get rid of ants in your basil plant before they establish a colony.
Remove any dead leaves or debris from the pot, as these can attract ants looking for food or shelter.
A clean basil plant is a less inviting home for ants in your basil plant.
2. Don’t Overwater Your Basil
Overwatering can lead to soggy soil, which attracts ants in your basil plant that like moist conditions.
Basil prefers slightly moist soil, but it hates sitting in water.
Water your basil only when the top inch of soil feels dry to the touch.
Make sure your pot has drainage holes so excess water can escape.
Crisper, drier soil will make your basil plant less appealing to ants.
3. Create A Physical Barrier Around The Pot
You can stop ants from even reaching your basil plant by creating a simple barrier.
Wrap a strip of double-sided sticky tape around the rim of the pot.
Ants walking up to get to your basil plant will get stuck on the tape.
Alternatively, place the pot in a shallow dish filled with a little water to create a moat.
These barriers are a great way to keep ants out of your basil plant while you work on long-term fixes.
4. Attract Natural Predators
Encourage ladybugs and lacewings to visit your garden, as they feast on aphids.
When the aphids disappear, the ants will have no reason to be in your basil plant.
You can plant flowers like dill, fennel, or marigolds nearby to attract these helpful insects.
Healthy predators are a natural, ongoing solution to avoiding ants in your basil plant.
So, How Do You Get Rid Of Ants In Your Basil Plant?
You can get rid of ants in your basil plant by removing the aphids that attract them and making the environment less inviting.
Start by blasting your basil with water and treating it with a dish soap spray to eliminate both pests.
Use neem oil or diatomaceous earth for tougher infestations.
Then, prevent future ants that may find their way back to your basil plant.
Hope this guide helps you enjoy a healthy, ant-free basil plant for all your cooking needs.
