1. Identify Grasshoppers
Grasshoppers are typically brown or green insects measuring around 2 inches (5 cm) long. They have a narrow, elongated body with large, angled hind legs. Their heads are vertically aligned with their bodies, and they have chewing mouth parts for feeding on vegetation. Spotting grasshoppers can be challenging due to their excellent camouflage with plant foliage. Some species resemble twigs, leaves, or bark on plants.
2. Understand the Grasshopper Life Cycle
Grasshoppers start as nymphs hatching from eggs laid by female grasshoppers. Nymphs molt several times before becoming adults, which takes 40 to 60 days. Adult grasshoppers can consume up to half their body weight daily, causing significant damage to garden landscapes.
3. Prevention and Control Strategies
a. Interrupt Their Life Cycle
Scratch the soil surface where grasshoppers lay their eggs (usually in the top two inches). This disrupts their life cycle.
b. Squish or Blast Small Nymphs
When grasshoppers are small, squish them or use a hose nozzle to jet-blast them off plants.
c. Use Bird Netting
Cover your plants with bird netting to prevent grasshoppers from feasting on them.
d. Early Intervention
Be aware of the three-year cycle of grasshopper infestations and act early to reduce their population.
4. Natural Pest-Control Methods
a. Neem Oil Spray
Mix warm water, liquid dish soap, and neem oil. Spray this mixture on plants to deter grasshoppers and stunt their growth.
b. Garlic Spray
Grasshoppers dislike strong scents like garlic. Create a concentrated spray by blending garlic with water and apply it to your plants.
c.
I have read that dusting your plants when they are damp with flour will help control them as well. I am trying it again as of today, I did some last week and it seemed as if it helped.
5. Avoid Attracting Grasshoppers
Keep your garden free of weedy areas, dead crops, and dry, undisturbed soil where grasshoppers lay eggs. Prune perennials after the first frost and water suspected breeding areas.
Remember, a balanced approach is essential. While grasshoppers can add to garden biodiversity in small numbers, controlling their population prevents them from becoming pests.
I hope you find these tips helpful in managing grasshoppers and protecting your garden! 🌱🦗
