Garden Pests
Grasshoppers
About 30 grasshopper species are considered
garden pests. They wreak the most havoc in the middle of the country.
Like many pests, grasshopper
populations rise and fall. In peak years, grasshoppers eat all the
plants they encounter, wiping out entire gardens and fields. Initial
signs of feeding by young grasshoppers are jagged and tattered holes
chewed in leaves.
Grasshoppers have long narrow bodies, with long angled back legs suited
to jumping, and a head featuring large eyes and chewing mouthparts. Adult
grasshoppers are winged and can fly a good distance, but juveniles are
wingless and feed verociously. Eggs generally start hatching from March
to June.
To thwart grasshoppers, keep an eye out for egg clusters. The best time
to use chemicals and baits is in the spring and early summer. You can
use malation, diazinon, acephate, carbaryl, chlorpyrifos, or bran-and
carbaryl bait.
Watch for them at night, noting where they’re located, and then
spray their favorite locations after dark.
If you’re invaded by grasshoppers, you may want to consider netting
for your plants.
