How long does Semaspore last?Created by Anonymous on July 19, 2012 at 6:17 pm
We are looking at using the organic bait for grasshoppers — we don’t want to spray. How long does it last, how often do you apply? We have dry grasslands all around us.

Which organic spray are you talking about? We've been using Semaspore Bait for years with great results. It really seems to keep the grasshopper numbers down.July 13, 2007 at 8:39 pm #13837
I got a one pound container of Semaspore Grasshopper bait last year, my only regret, is that I hadent gotten the five pound instead. It covered less than one fifth of my property, and this year even though I got a five pound bag of the bait, and haveing killed a bear minimum of 15,000,000 hoppers sofar, several times the amount of the hoppers still remain. Does anyone know anouther organic product that will work well along with the semaspore?July 18, 2007 at 3:29 pm #13838
I've sprayed the little buggers with Pyganic, an OMRI Listed pyrethrin spray, with varied success. You may also want to try EcoBran. It has a small percentage of chemical on it (not organic) but really does the job. They have a pamphlet on this site that talks about using the two baits together. Here it is:

I will try these sugestions as soon as posible. Does any one have a homade grasshopper control that is non-toxic?September 8, 2007 at 1:24 pm #13846
I wouldn't have gotten the hoppers under control, if it weren't for the help of this form and Planet Natural! Thanks a lot! As few as there were at egg laying time I shouldn't have anywhere nere the infeastation next year.May 26, 2010 at 4:27 am #13998
I've heard both that it will be the worst year for grasshoppers in 30 years, and that it will be the worst year since 1930,,,,bad and worse!
But the 50 pound bag of Semi-spore bait I got last year seemed to do the trick!
I'm only finding a few grasshoppers on the place, and usually by now they're everywhere!
Just the same I've got 150 pounds of wheat bran as well as the rest of the ingredients for some homemade bait I found out about last year!
One batch ingredients: 20 pounds wheat bran, one quart insecticide such as liquid seven (I used a pint of Malathion and am going to try to figure out how much Pyganic would substitute), 1 quart molasses, 1 quart veggie oil, 2 gallons water, and a few drops of dish-soap to emulsify the oil and water.
Mix oil, water, dish-soap, molasses, insecticide, stir in wheat bran and mix till evenly absorbed, let sit over night, stir again, let sit 4 hours and scoop clumps out around fruit trees and anything else you want to protect!
The first three years I have had this place they were worse than the year before, which the first year they were terrible!
Then last year in the spring they were a reasonable number and I thought I had them licked!
Till they did there usual trick of coming from everywhere around to attack my place, I may buy the Semi-pore again if they are bad enough, but hopefully it will carry over good enough to this year!
I also ordered and received 50 Praying mantis egg cases,,,I just don't know what I'll do if I don't have a better victory this year!July 19, 2012 at 6:17 pm #14043
hello, so i have a question about this semaspore bait. i ordered some and before i use it i want to know why it says to only use it when no above ground harvestable food commodities are present. or apply after the harvest crop has been removed, im in the middle of summer and have tons of blooms and lost of veggies and fruit that are already producing, should i not use this stuff??June 26, 2016 at 2:55 pm #202653
You can thank the EPA for the scary labeling. Bottom line, it costs the manufacturer a lot of money to do the additional testing that the EPA requires to approve a product for use on food crops. Rest assured that Semaspore Bait is non-toxic to people, pets and the environment. This naturally occurring protozoa is only toxic to grasshoppers and one species of cricket.
Hope this helps!
