As a control measure, it’s best to wait until next spring. With that said, some growers will apply Semaspore Bait on older grasshoppers late in the year to get the infection started — the spore overwinters in infected egg pods.

The USDA has mentioned that Semaspore Bait will persist in an area for up to three years — and maybe longer, they stopped testing after three years — after application. Keep in mind, however, that the spore can get overrun if pest populations are high and pretreatment will be necessary.

Semaspore Bait provides effective, long-term grasshopper control and is OMRI Listed for use in organic production.
