What do I do about a garden grasshopper invasion?

Tips for grasshopper control:

  • Catch and kill grasshoppers in the early morning when they are least active.
  • Use a sweep net to remove grasshoppers from plants.
  • Expose grasshopper eggs to predators and the elements by digging in the ground in early spring.
  • Till vacant land in the mid- to late summer to reduce potential egg-laying sites.
  • Keep ground free of weeds to discourage egg laying.
  • Two-feet-tall, smooth surface, angled barriers can keep grasshoppers out of gardens.
  • Floating row covers can protect plants.
  • Grasshoppers are attracted by sicky yellow traps.
  • Containers filled with 10% solution of molasses and water, covered with a film of canola oil and burried so rims are at ground level can be used to trap grasshoppers.
