Semaspore Bait™ - Organic Grasshopper Control

Stop Grasshoppers Dead in Their Tracks!

How it Works: Semaspore Bait contains Nosema locustae, a naturally occurring single celled protozoan infects all stages of developing grasshoppers, mole crickets, Mormon and black field crickets. Nosema when ingested creates a disease that is specific to these pests. It will not harm any other living species.

Grasshoppers typically lay eggs in Southern exposure locations in hilly, sandy soil. As they hatch they will begin to travel to their food source (your garden or farm). Head them off by applying Nosema in swaths as a barrier about 1 foot wide, or by generally broadcasting product in and around area to be protected. Grasshoppers will begin to feed on spore-infected bran. After eating Semaspore grasshoppers become sick, eat less, and begin to die. The disease spreads to healthy grasshoppers through cannibalism. In 2-4 weeks, 50% of the 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. Nosema works best when applied to younger stages of hoppers (1/4 to 1/2-inch long). Heavy infestations may require repeat applications.

Application rate: 1-2 lbs per acre, with second application if necessary 4-6 weeks later. Can also be used indoors. Apply in house plant containers.

Note: Semaspore has an 8 week shelf life - 5 months if refrigerated.

Why Restrictions? All products labeled as pesticides, whether the product is natural, organic or man-made, are regulated by each state. Restrictions for sale in a state occur because the manufacturer of the product chooses not to register that product there. If the product is not a pesticide, there may be other regulations that the vendor cannot easily meet having to do with labeling.

The reason for non-registration is usually economic: each state requires a fee that is paid annually, or the cost of re-labeling for just one or a few states is too high. For instance, each pesticide registered for sale in Arizona is assessed a $100 fee yearly for each size product.

If you would like this product in your state, let us know and we will communicate your interest to the manufacturer. If there is enough interest, the manufacturer may decide to register the product you want.

In the meantime, call us and we will help you find a similar product that we can substitute that is registered in your state.

Works great! Would suggest a second application - By obreezey on Jul 16, 2010
Had a full jar of this stuff that was actually expired. We decided to use it anyway. It reduce number of crickets from coming in our house, but now I am starting to see some more. So I would suggest the 2nd application as suggested 4 to 6 weeks after first application. I think this works pretty good considering it was expired when we used it.

Wonderful product!! - By Rhonda on Jul 8, 2011
I used this product a few years ago when the grasshoppers were so bad you couldn't walk out the front door without waving your hands around to keep the grasshoppers from jumping on you. It took about a month to really see a difference. By the end of the summer I hardly had any at all. For the next 2 seasons I had very few grasshoppers! Would recomend this product to everyone!

This stuff really works! I was dubious at first, I put it in my grasshopper infested garden about a month ago. Now there are very few hoppers and the ones that are around are sickly. I can catch them because they are so slow, and some of them writhe around. I bought another 5 pounds, and Arbico sent the stuff pronto. Great experience.

It really works - By Marsha on Jul 22, 2011
I decided to try this after grasshoppers ruined my garden last year. I applied it early and only saw a few small nymphs all spring, even though others in my area report having major problems. When I started seeing an increase in June, I applied it again and noticed a difference within 2-3 weeks.

Worked as advertised - By James Thatcher on Jul 28, 2011
Last year the grasshoppers ate up all but my tomatoes. I tried boiling tomato leaves and using the tea to spray on other plants but it only worked for a day or two. This year I used Semaspore and the results are great. Being a bad year for grasshoppers in our area others are complaining of the damage but so far we have not had that problem. I would recommend this product to others.

Grasshoppers Tamed! - By CJ on Aug 31, 2011
This stuff works! I had a bumper crop of grasshoppers eating my plants because with the drought they were the only things living. A couple of weeks after application of Semaspore Bait...I'm seeing a few, but very few. ARBICO shipped the product quickly and I got exactly what I ordered.

Outstanding product. Safe and worked better than anything else I have tried. I will be a returning customer.

Semaspore Bait - By Bia on Sep 19, 2011
This is our second year using the product. We still can't tell the results yet but as per our prior experience we know that it works. Thanks...

Great product - By FR on Oct 10, 2011
It really gets the cricket population under control. My dog goes in the yard after I have spread it and she has never been affected. I have been using this product for 2 years with good success. I highly recommend it.
