Grasshoppers

Read more about controlling grasshoppers.In addition to management techniques recommended by UCCE, a relatively new, naturally occurring microbe called Nosema locustae can be used to infect and kill grasshoppers and some types of crickets. In spring and early summer the young are most vulnerable, and Nosema locustae may be the answer. Dissolve the spore in water, add it to a bran mixture (grasshoppers' favorite food) to form a bait; or you can order a commercially prepared NoLo bait on-line. Disperse the bait over the garden.
As grasshoppers feed on the Nosema-bran mixture, they become infected and slowly die. Surviving grasshoppers retain sufficient infection to reduce or inhibit reproduction. The infection is also transmitted when infected grasshoppers are eaten by healthy ones. Note that this bait is not fast-acting but will, over time, control the grasshopper population.
