In this post, we’ll explore why grasshoppers are drawn to basil, the best methods to keep grasshoppers off basil, and how to make your garden less inviting to them.
 
Let’s dig in and get your basil safe from those hungry hoppers.
 

Why Grasshoppers Love Basil and How to Keep Grasshoppers Off Basil

Grasshoppers are opportunistic feeders, and basil’s soft, aromatic leaves are like a buffet to them.
 
When you’re trying to keep grasshoppers off basil, it helps to understand their behavior—they’re most active in warm, dry weather, and they’ll munch on just about any green plant they can find.
 
Basil’s succulent texture and mild scent make it a prime target, especially when other food sources are scarce.
 
The key to keeping grasshoppers off basil is to make your plants less accessible and less appealing, while also reducing the grasshopper population in your yard.
 
Here are the core strategies that work best when you want to keep grasshoppers off basil for good.
 

1. Use Floating Row Covers as a Physical Barrier

One of the most reliable ways to keep grasshoppers off basil is to cover your plants with floating row covers.
 
These lightweight fabrics let in sunlight, air, and water while creating a physical barrier that grasshoppers simply can’t get through.
 
You can drape the cover directly over your basil plants or use hoops to keep it elevated.
 
Make sure to secure the edges with soil or stakes so grasshoppers can’t sneak in from the sides.
 
This method is especially effective because it doesn’t harm the grasshoppers—it just keeps them away from your basil.
 
And since basil loves warmth, the row cover can even give your plants a little extra heat during cooler nights.
 

2. Plant Trap Crops to Distract Grasshoppers

Another smart trick to keep grasshoppers off basil is to plant something they like even more, like lettuce, beans, or corn, on the edges of your garden.
 
These trap crops will attract grasshoppers away from your basil, giving you a sacrificial plant that takes the damage instead.
 
You’ll still need to monitor the trap crops, but this strategy can significantly reduce the pressure on your basil.
 
Just remember to remove any grasshoppers you find on the trap crops before they multiply and spread.
 
This method works best when you have space to dedicate a few plants as decoys.
 

3. Introduce Natural Predators to Your Garden

If you want to keep grasshoppers off basil without lifting a finger, encourage natural predators to visit your garden.
 
Birds, chickens, and even spiders love to feast on grasshoppers, and they can help control the population for you.
 
You can attract birds by setting up a birdbath or a small feeder near your basil patch.
 
If you have chickens, letting them scratch around your garden in the late summer can be a great way to reduce grasshopper numbers.
 
Just be careful that chickens don’t eat your basil too—they’re not picky either!
 
The more predators you invite, the easier it becomes to keep grasshoppers off basil naturally.
 

Natural Repellents That Keep Grasshoppers Off Basil

Sometimes you need a more direct approach to keep grasshoppers off basil, and natural repellents can be a lifesaver.
 
These options are safe for your plants, your family, and beneficial insects, unlike harsh chemical pesticides.
 
Let’s look at the most effective homemade and store-bought repellents you can use.
 

1. Garlic Spray: A Strong Scent They Hate

Grasshoppers have a highly sensitive sense of smell, and garlic is one scent they absolutely can’t stand.
 
To make a garlic spray, crush a few cloves of garlic and steep them in water overnight.
 
Strain the mixture, add a drop of dish soap to help it stick, and pour it into a spray bottle.
 
Spray your basil plants thoroughly, especially the undersides of leaves where grasshoppers like to hide.
 
Reapply the spray every few days or after rain to keep the protection strong.
 
This simple DIY solution works wonders to keep grasshoppers off basil without any toxic residue.
 

2. Neem Oil: A Double Duty Defender

Neem oil is a popular organic option that not only repels grasshoppers but also disrupts their life cycle.
 
When grasshoppers feed on basil treated with neem oil, they ingest a compound that interferes with their ability to grow and lay eggs.
 
Mix neem oil with water according to the label instructions and spray your basil in the early morning or late evening.
 
The oil coats the leaves with a bitter taste that grasshoppers find unappealing.
 
You’ll need to reapply neem oil every week or so, but it’s a reliable way to keep grasshoppers off basil for the long term.
 
Just avoid spraying during the heat of the day to prevent leaf burn.
 

3. Diatomaceous Earth: A Sharp Surprise

If you prefer a no-spray solution, food-grade diatomaceous earth is another excellent tool to keep grasshoppers off basil.
 
This fine powder is made from fossilized algae and has microscopic sharp edges that cut through grasshoppers’ exoskeletons, causing them to dehydrate.
 
Sprinkle a light dusting of diatomaceous earth around the base of your basil plants and on the leaves themselves.
 
It works best when dry, so reapply after watering or rain.
 
Be sure to wear a mask while applying it, as the dust can irritate your lungs if inhaled.
 
When used correctly, diatomaceous earth can effectively keep grasshoppers off basil while remaining safe for your soil.
 

Garden Habits That Help Keep Grasshoppers Off Basil

Beyond barriers and sprays, your overall garden maintenance plays a huge role in keeping grasshoppers off basil.
 
Grasshoppers thrive in weedy, overgrown areas where they can hide from predators and find plenty of food.
 
By cleaning up your garden, you’ll make it less inviting for them to stick around.
 
Here are a few habits to adopt that will naturally reduce grasshopper pressure on your basil.
 

1. Remove Weeds and Tall Grasses

Grasshoppers lay their eggs in undisturbed soil and tall grass, so eliminating these hiding spots is crucial.
 
Keep the area around your basil patch free of weeds and mow any nearby grasses regularly.
 
This exposes grasshoppers to birds and other predators, which helps control their numbers.
 
Tilling the soil in late summer can also destroy grasshopper eggs before they hatch the next spring.
 
A clean garden is your first line of defense when you want to keep grasshoppers off basil.
 

2. Water Your Basil in the Morning

Grasshoppers are most active in dry conditions, so keeping your basil well-watered can make it less appealing.
 
Watering in the morning ensures your plants stay hydrated throughout the day, and the moisture can deter grasshoppers from lingering.
 
Just avoid overhead watering in the evening, as wet leaves overnight can lead to fungal diseases.
 
A consistent watering schedule keeps your basil healthy, and healthier plants are better able to recover from any grasshopper damage.
 
Plus, a lush, moist garden is less attractive to these drought-loving pests.
 

3. Handpick Grasshoppers When You See Them

If you only have a few grasshoppers, the simplest way to keep grasshoppers off basil is to pick them off by hand.
 
Head out to your garden in the early morning when grasshoppers are sluggish and easier to catch.
 
Drop them into a bucket of soapy water to dispose of them quickly.
 
Check your basil plants every few days, especially the undersides of leaves, to catch any stragglers.
 
This hands-on method is effective and gives you a chance to inspect your plants for other issues too.
 
It’s a small effort that pays off big in protecting your basil harvest.

The key to keeping grasshoppers off basil is to be consistent and proactive, rather than waiting for an infestation to take hold.
 
Start with the most accessible method that fits your garden setup, and add others as needed to build a strong defense.
