What are Grasshoppers and How to Get Rid of them

Grasshoppers are large, hard bodied, chewing insects, typically 5 cm and up to 12 cm+ long. Powerful hindlegs used for jumping make a snapping noise, as do their wings. Males during the day make a chirping sound produced by rubbing their legs and wings together. Two large compound eyes provide for quick reflexes.

There are many different species of grasshoppers, generally in colours of greens, browns and blacks, sometimes in oranges, blues, and reds, all in varying patterns.

Lifecycle:

Females grasshoppers lay eggs in either the ground or on plants. Eggs hatch into nymphs (young) that grow through various stages similar in appearance to adult forms, often developing wings in adulthood. 

Habitat:

Grasshoppers can be found hiding in the ground, on stems or on leaves. Most are solitary, however, can also form large groups. Grasshoppers have an insatiable appetite, feeding on large volumes of plant material including the leaves, stems, flowers and fruits of fruit trees, vegetables and ornamental trees and shrubs. Grasshoppers are most active during the warmer months, especially during periods of drought, as home gardens unwittingly provide them with both habitat and food.

Natural enemies:

Grasshoppers have various natural enemies including ants, spiders, various fly species, mites, nematodes, birds and small mammals. 

 

Best Treatment for Grasshoppers

Keep your garden well-watered and remove dead organic material to reduce grasshopper habitat. For vegetable garden beds, prior to replanting, cultivate the soil and leave exposed, which can encourage birds and other animals to predate on eggs laid in the soil. 

For the control and treatment of grasshoppers on garden plants, we strongly recommend Yates Baythroid Advanced Insect Killer for Gardens.

 

Symptoms of Grasshopper damage
