Best Organic Solutions (Ranked)

Solutions ranked by reliability tier — start with Tier A options.

Long-term population suppression via protozoan disease

Fungal infection — best in humid conditions

Spinosad Tier A

Contact kill of nymphs and small adults

Biological Controls

Birds (especially guinea fowl), parasitic flies, Nosema spore spread through cannibalism

Prevention

Apply Nosema bait early when nymphs are small. Till garden edges to destroy egg pods. Guinea fowl are voracious grasshopper predators.

Common Mistake

Waiting until grasshoppers are adults — biological controls work best on young nymphs. Adult grasshoppers are extremely difficult to control organically.
