As a passionate gardener, nothing delights me more than watching my autumn sage burst into vibrant reddish-purple blooms in the fall.

If you’ve dealt with these hopping pests devouring your autumn sage you know they can rapidly defoliate the plant and stunt its growth.
In this comprehensive guide, you’ll discover smart organic strategies and products to banish grasshoppers from your autumn sage for good I’ll share natural deterrents, physical controls, biological methods, organic sprays, and preventative care to protect your plant’s health and beauty Let’s explore how to safely, effectively give grasshoppers the boot!
Understanding Grasshoppers and Their Destruction
Grasshoppers are insatiable leaf and flower eaters. With their strong mandibles, they can quickly chew through plant material, leaving holes and necrosis in their wake. An infestation can decimate autumn sage in no time, so swift action is essential at first signs of damage
Watch for these common symptoms of grasshoppers on autumn sage:
- Chewed leaves with ragged edges
- Flowers missing petals
- Presence of grasshoppers on foliage
- Small brown pellets of frass (grasshopper waste)
Daily monitoring helps detect infestations early when they are easiest to treat. Inspect the undersides of leaves and flowers where grasshoppers like to hide.
Natural Ways to Deter Grasshoppers
The safest, most eco-friendly solutions should be your first line of defense against grasshoppers. Here are some effective natural deterrents:
Strong Water Spray
Grasshoppers dislike moisture. Give plants a strong blast from the hose to knock pests off foliage. Focus the stream underneath leaves and on flowers. Repeat 2-3 times per week.
Hot Pepper Spray
The fiery capsaicin in hot peppers drives away grasshoppers. Mix 2-3 tablespoons of ground cayenne or chili powder with 1 gallon of water. Add several drops of dish soap and strain before spraying plants. Reapply after rain.
Garlic Spray
The pungent odor of garlic repels grasshoppers. Blend 8 garlic cloves with 1 quart of water. Allow to sit overnight, then strain. Mix 1 part garlic concentrate with 10 parts water and spray plants.
Neem Oil
Extracted from neem trees, this natural pesticide coats plants with a bitter substance that deters grasshoppers. Follow label directions for correct dilution and application.
Physical Removal Methods
Manually eliminating grasshoppers is time-consuming but highly effective. Here are two hands-on techniques:
Handpicking
Check autumn sage frequently and pick off any grasshoppers you spot. Drop them into a container of soapy water to finish them off.
Bug Vacuum
For larger infestations, use a handheld bug vacuum. Capture grasshoppers swiftly without chemicals or touching them. Release into a bucket of soapy water.
Biological Control Options
Natural predators offer safe grasshopper control by feeding on them. Attract these beneficials to your garden:
Lizards
Place rock piles for lizards to sun themselves. They’ll happily snack on grasshoppers.
Birds
Entice insect-eating birds with feeders and birdhouses. Chickens and guineas are especially voracious grasshopper consumers.
Predatory Insects
Introduce ladybugs, praying mantises, lacewings, and ground beetles by providing pollen and nectar sources. They’ll feast on grasshopper eggs and larvae.
Organic Sprays as a Last Resort
If the above methods fail to protect autumn sage from grasshopper damage, limited use of organic sprays is warranted:
Spinosad
This biological insecticide made from bacteria kills grasshoppers on contact while safe for people and pets. Spray foliage thoroughly and avoid blooms to protect pollinators.
Pyrethrin
Derived from chrysanthemums, pyrethrin insecticides rapidly knock down grasshoppers. Use pyrethrins sparingly in the evening when pollinators are less active.
Neem Oil
In addition to repelling grasshoppers, concentrated neem oil sprays will kill nymphs and adults. Dilute according to label instructions and cover leaves, stems, and flowers.
Preventing Future Grasshopper Outbreaks
Once you evict existing grasshoppers from your autumn sage, take these steps to deter future infestations:
-
Remove weeds and debris where grasshoppers breed.
-
Plant nectar-rich flowers to draw in beneficial predatory insects.
-
Use lightweight row covers over plants to form a barrier against grasshoppers.
-
Introduce nematodes to soil to kill grasshopper nymphs underground.
-
Trap grasshoppers in early spring using pheromone lures.
Mealybugs and Aphids
Notice a cottony mess? Mealybugs are making themselves at home. These fluffy fiends suck sap and weaken your Autumn Sage. And if you spot clusters of tiny insects, those are aphids. Theyre like miniature vampires for plants, draining them of nutrients.
If a cloud of tiny insects erupts from your plant when you touch it, youve got whiteflies. These pests are like unwanted confetti, fluttering about and feeding off your plant. Theyre hard to miss once they get going, so watch for their disturbance dance.
Spot the Invaders: Identifying Common Pests
Webbing on your Autumn Sage? Youve got spider mites. These tiny terrors spin their homes under leaves, leaving behind a speckled look. Waxy bumps? Thats scale, clinging to your plant like unwanted stickers. Both pests suck the life out of your sage, so keep your eyes peeled.

Does Sage repel grasshoppers?
Just like rosemary, growing sage to repel pests is an effective natural deterrent. Like repelling other pests from your yard, the strong scent of sage will discourage the presence of grasshoppers. It makes a great lavender companion plant to strengthen your repelling efforts, as lavender is also an aromatic herb that keeps different pests away.

An outbreak (when swarms of insects hatch and begin feeding simultaneously) can devastate a small garden in just a few hours. Huge appetites, combined with the ability to jump or fly from plant to plant easily, make grasshoppers one of the most destructive garden pests.
Can neem oil kill grasshoppers?
A homemade neem oil spray can act as an organic grasshopper repellent and pesticide. Use two teaspoons of neem oil and a teaspoon of liquid dish soap for every quart (1 l) of water. Combine the ingredients in a spray bottle and apply to plants and crops where grasshoppers frequent.
