Little grasshoppers eating everything! #876716

Asked July 10, 2024, 4:19 PM EDT

I live just south of Fort Collins and we have almost an infestation of these little brown and green grasshoppers and they are destroying all my plants outside. They’re eating the annuals as well as all of the leaves in my vegetable garden please advise. Is there anything to help mitigate, I have tried neem oil, and nothing seems to work. Thanks

Hi, Susan,
Thanks for contacting Ask Extension.
Grasshoppers are indeed plaguing most gardens this time of year. Controlling them is difficult since they are plentiful and very mobile.

Netting or row covers over garden beds may mitigate their depredation.

The attached CSU Fact Sheet discusses possible controls, including baits and insecticides.

Baits coated with carbaryl can be effective, such as EcoBran.

Insecticides need to be used with care, you must always read and follow the manufacturer’s instructions. They can harm pollinators and other beneficial insects as well as the pests, especially if sprayed on flowering plants.

Please review this information and if you have any additional questions on this or any other gardening issue, don’t hesitate to contact Ask Extension again.

Thanks,

Kathy
