Anyone have suggestions for keeping grasshoppers from chewing on plants in an outside grow? Been growing for years and never had a problem with grasshoppers like i do this year. They chewed the stems and took entire branches out,
Find something that chews on grasshoppers…
Get some spiders and release, they will probably keep all pests down
Agreed 100%
Unfortunately I’m busy the next few weeks ![]()

I deal with grasshoppers every year they’re a pain in the ass. Not much kills them Nolo bait is one. I had to wrap chewed branches with teflon tape last year.
Garlic will deture them.
Someone just recently suggested some type of flour but I cant remember. Maybe they’ll chime in. Mainly I just kill them with my fingers.
I looked it up it was @David1974 that said to use flour.
Thanks for the tips. I sprinkled flour on them after spraying them with garlic spray but not sure how much it helped. Not sure why but they seem to pick on one plant in particular. Very frustrating!
They mainly chewed on my Jack Herar last year only did a little damage to the Toxic truffles next to it. My other plants were barely touched
Anywhere where they’ve chewed the bark off branches, wrap it with teflon tape. They wont chew through it.
I had a rough go of it with grasshoppers early on this season. I couldn’t find Grasshopper specific bait so I tossed down Diatomaceous Earth pretty often, removed them by hand and into a bucket of soapy water in addition to scooping up some wasp nests and sticking them around the garden. Honestly I’m not sure any of it worked or if they finally just died off from crap weather.
If you choose to bring wasps into the mix, seriously plan out how you’re going to capture the nest. I did it at night using mason jars and bbq mitts lol
They were pissed off but a little more lethargic.
Make sure you’re using all purpose flour just a light sprinkling all over your plants when the grass hoppers eat the leaves the flour will gum up their mouth and they’ll die
Where can i get spiders
I just tried looking and it seems hard to do. Can try to invite wasps with sweet smelling sugars. Hope you’re able to get rid of them its why I’m scared to try outdoors
There seems to be less of them after sprinkling flour on them, hopefully under control. I have been growing in the same place for years and never had this problem. Some leaves have been eaten in previous years but never had them chew entire branches off. They took the top off of my Mountain Gold I got from Colorado Sativas.
That was me last year. I’ve been growing here since 2018 always had a few grasshoppers eat a few leaves here and there. I picked more leaves than they did until last year. They’re chewing stems again this year. Im about to go out and wrap a brach right now. I noticed it yesterday while spraying. What did you use to apply the flour.
I just used my hand, probably would be spread more evenly if I were to use a sifter I guess, but it seems to spread ok.
Praying mantis eat grasshoppers you can buy an egg and a ton of them come out of it
Just stole this off the internet
Yes, mint essential oil can be effective against grasshoppers. When ingested, mint oil can harm grasshoppers in a number of ways, including:
- Delayed maturity: Mint can delay a grasshopper’s maturity by 11 days.
- Decreased egg laying: Mint can shorten a female grasshopper’s oviposition period by 18 days, and reduce the number of eggs she lays from 152 to 56 over her lifetime.
- Fewer hatched eggs: Only 45% of the eggs laid by grasshoppers that have ingested mint oil hatch, and half of the hatched eggs are deformed.
Other natural repellents that can be used against grasshoppers include:
- Strong-smelling substances
Grasshoppers dislike the smell of garlic, onion, cayenne pepper, vinegar, and hot pepper. You can mix these substances with water and spray them on plants.
- Neem oil
This naturally occurring pesticide can be sprayed on plants to create a protective barrier. You can mix neem oil with water and apply it to plants, and you can eat the plants afterwards if you wash them thoroughly.
- Plants
Some plants that are known to repel grasshoppers include forsythia, crape myrtle, passion vine, goldenrod, juniper, and Russian sage.
Thanks, i have tried a garlic/vinegar spray, neem oil, sprinkled the leaves with flour, even used wasp spray on them. My hope was someone with information on how to keep the infestation minimal next year. They basically took the entire top off of one plant, still has some buds on the side branches.
