Grasshoppers may seem harmless, but when populations spike, they can cause severe damage to lawns, gardens, shrubs, and field crops. In some regions of the U.S., outbreaks lead to widespread defoliation and thousands of dollars in landscape loss. Effective grasshopper control requires a combination of early detection, habitat modification, and targeted treatments.
Why Grasshoppers Become a Problem
Grasshoppers thrive in warm, dry summers and areas with:
Tall grass and weeds
Overgrown property edges
Untreated fields or vacant lots
Dry soil conditions
Abundant plant growth
Once they move into residential yards, they feed aggressively on:
Garden vegetables
Ornamental plants
Flowers and shrubs
Turfgrass
Small fruit trees
A single grasshopper can eat half its body weight per day, which adds up quickly when dozens or hundreds are present.
Signs of a Grasshopper Infestation
Common indicators include:
Ragged, chewed leaves
Reduced flowers or buds
Bare stems on garden plants
Grasshoppers jumping or flying when disturbed
Increased populations in dry, hot months
You may also spot egg pods in soil during fall, which hatch the following spring.
How to Control Grasshoppers Effectively
1. Reduce Overgrown Vegetation
Grasshoppers often build up in unmaintained areas before invading lawns.
Mow grass regularly
Remove tall weeds and brush
Trim property edges and fence lines
Keep vegetation away from structures
This makes your yard less attractive as a habitat.
2. Water Properly & Maintain Healthy Plants
Healthy, well-watered lawns and gardens bounce back faster from feeding damage.
Dry, stressed plants attract grasshoppers and suffer more injury.
3. Use Targeted Treatments
Grasshopper control works best with early-season applications when nymphs (young grasshoppers) are active.
Common treatment options:
Residual insecticides along yard perimeters
Spot-treating shrubs, garden beds, and ornamentals
Barrier treatments between your yard and adjacent fields or vacant lots
Bait formulations that grasshoppers consume
Professionals use EPA-approved products designed to reduce populations safely for families, pets, and pollinators.
4. Protect Sensitive Plants
Use physical barriers when necessary:
Garden netting
Row covers
Mesh screens over small fruit trees
Temporary garden enclosures
These prevent feeding without chemicals.
5. Treat Breeding Areas in Fall
Grasshoppers lay eggs in bare, dry soil.
To reduce next year’s population:
Till or rake bare soil patches
Water dry areas occasionally
Remove debris piles
Apply late-season treatments if needed
Early disruption reduces egg survival.
Prevention Tips to Keep Grasshoppers Away
Long-term prevention works best when combined with seasonal treatments:
Maintain a clean, low-growth landscape
Remove yard debris and brush piles
Keep lawn well-watered in summer
Use mulch around garden beds
Monitor for early signs each spring
Homeowners near rural or agricultural areas may need yearly preventive treatments.
When to Call a Professional
Grasshopper outbreaks can escalate quickly. Contact a pest control service if:
Grasshoppers are spreading across the entire yard
Plants, vegetables, or shrubs show heavy feeding
DIY sprays fail to reduce the population
You live near fields, pastures, or large undeveloped land
Professionals use specialized treatments, bait options, and long-lasting barriers to protect both lawns and gardens.
Final Thoughts
Grasshopper control is most successful when started early and supported with good yard maintenance. By reducing breeding sites, protecting vulnerable plants, and applying targeted treatments, you can keep your landscape healthy and prevent costly damage.
