Semaspore Bait contains Nosema locustae, a naturally occurring grasshopper control. After eating Semaspore, grasshoppers become sick, eat less and begin to die. The disease spore spreads to healthy grasshoppers through cannibalism. OMRI Listed for use in organic production.
WHAT TO EXPECT:
In 2-4 weeks, 50% of the grasshopper population will die, and most survivors will be infected to continue spreading the disease. Infected survivors eat 75% less than healthy grasshoppers and lay fewer eggs. Will NOT harm people, pets or the environment.

When I bought my 5 acres in 2006 there was a significant grasshopper population, but it is now minimal due to application of Semaspore every year since then. It is expensive, but worth every penny when you consider the damage that grasshoppers can do.

We have 30 acres so have bad problem w/grasshoppers and have been using this for about 7 yrs and feel that we have somewhat control of course not totally but sure not as bad as used to be. I believe in this product. And plus it's safe for my animals and all other critters and creatures.

I tried this product as directed and felt it slightly diminished the grassphopper problem, but it was not worth the money for the minimal to no results I got. I felt it probably did something for the grasshoppers I still had a big grasshopper issue. Try other organic home remedies, they work better than this did for me.
