Grasshopper Control Methods: Effective Management Tips

If you’re a gardener dealing with pesky grasshoppers, you know how frustrating it can be when these insects wreak havoc on your plants. From their destructive feeding habits to their ability to migrate and cause widespread damage, managing grasshoppers requires effective control methods.

Grasshoppers have a distinct life cycle, with eggs laid in the soil in the fall and hatching in the spring. As they grow, they molt several times before becoming adults. While they prefer young green plants, they will devour almost any green plant during major outbreaks.

To help you manage grasshoppers and protect your garden, here are some effective tips:

Key Takeaways:

  • Learn about the grasshopper life cycle and feeding habits to better understand their behavior.
  • Handpicking, using protective covers, and creating trap crops can be effective control methods.
  • Consider insecticide treatments for larger infestations.
  • Explore organic and cultural control methods, such as early seeding and crop rotation.
  • Coordinated area-wide control is recommended for more significant grasshopper populations.

Identifying Grasshoppers and Understanding Their Behavior

Grasshoppers are fascinating insects with unique characteristics that set them apart from other creatures. Their distinctive hind legs, well adapted for jumping, make them easily recognizable. With a robust body and relatively short antennae, they display an intriguing appearance.

During late summer and fall, grasshoppers lay their eggs in the soil, patiently waiting for the arrival of spring. As the temperatures rise, the eggs hatch, and the nymphs emerge, ready to explore and feed on nearby plants.

The nymphs undergo several molts, shedding their exoskeletons, until they reach the adult stage. This transformation is a crucial part of the grasshopper life cycle, enabling their growth and development.

While grasshoppers have their preferences, such as young green plants like lettuce, beans, corn, carrots, onions, and annual flowers, they are opportunistic feeders. During major outbreaks, their appetite extends to a wide range of plants, posing a significant threat to gardens and crops.

Understanding the behavior and life cycle of grasshoppers is essential for effective control. By identifying these insects and gaining insights into their feeding habits, you can take proactive measures to protect your plants and minimize damage.

Grasshopper Control Methods and Strategies

Managing grasshoppers can be a challenging task, but there are effective methods and strategies that can help you prevent and control their damage. When dealing with low grasshopper populations, an organic approach like handpicking and squashing them can be surprisingly effective.

For those with a larger garden or farm, protective covers such as cones, screened boxes, or floating row covers can provide an additional layer of defense. These covers can offer protection against grasshoppers, particularly when their numbers are not overwhelming.

Another proactive strategy is to create an attractive green border surrounding your garden. This green border serves as a trap for grasshoppers, diverting them away from valuable vegetables and flowers. By luring them to this designated area, you can minimize the damage they cause to your main garden.

In agricultural and rangeland areas, treating grasshoppers with insecticides early in the season when they are still nymphs is a common practice. Baits containing carbaryl can be used, but it’s essential to reapply them regularly if you notice continuous migrations of grasshoppers.

Biological control options are also available for those seeking organic solutions. One such option is the use of the protozoan Nosema locustae, which can be effective in reducing grasshopper populations without synthetic chemicals. Additionally, implementing cultural control methods like early seeding of crops and crop rotation can help prevent grasshopper infestations.

Overall, when facing grasshopper infestations, a multi-faceted and coordinated approach in your control efforts is recommended, particularly for more extensive outbreaks. By implementing these strategies and methods, you can better manage and control grasshopper populations while minimizing the damage they inflict.


Q: How do I identify grasshoppers?

A: Grasshoppers can be easily identified by their hind legs, which are well adapted for jumping. They have a robust body and relatively short antennae.

Q: What is the life cycle of grasshoppers?

A: Grasshoppers lay their eggs in soil during late summer and fall, and the eggs hatch in spring. The nymphs feed on nearby plants and molt several times before reaching the adult stage.

Q: Which plants do grasshoppers prefer to feed on?

A: Grasshoppers prefer young green plants, especially lettuce, beans, corn, carrots, onions, and some annual flowers. However, they can feed on a wide range of plants during major outbreaks.

Q: How can I control grasshoppers in my garden?

A: There are several methods and strategies for controlling grasshoppers. When populations are low, handpicking and squashing them can be effective. Using protective covers, creating trap crops, or employing insecticide treatments are also viable options.

Q: Are there any natural or organic solutions for grasshopper control?

A: Yes, cultural control methods like early seeding of crops and crop rotation can help reduce grasshopper populations. Additionally, biological control options using the protozoan Nosema locustae are available.

Q: What should I do if I have a large-scale grasshopper infestation?

A: Coordinated area-wide control is recommended for larger-scale infestations. In agricultural and rangeland areas, treating grasshoppers with insecticides early in the season when they are still nymphs can be effective.

Q: Can I use baits for grasshopper control?

A: Yes, baits containing carbaryl can be used to control grasshoppers. However, they may need to be reapplied if migrations continue.
