Late-Season Grasshopper Control Strategies

In mid-September, a yard was overrun with grasshoppers of all sizes. The expert noted that insecticides work well on small nymphs (under 1 inch) but are less effective on large adults. Since the population was already mature, two sprays seven days apart were recommended for partial control.

Cultural practices help long-term: till garden beds in fall to expose eggs, encourage birds and beneficial insects, and use row covers on vulnerable crops. A guide to grasshopper control in yards and gardens was referenced for detailed options.

Quick Tips:

• Spray early morning when grasshoppers are less active.
• Target nymphs in spring for best results.
• Nosema locustae bait (organic) affects only grasshoppers.
• Accept some damage—complete eradication is unrealistic.

Next year, start monitoring in May for early intervention.
