Hello Vickie,

Thanks for stopping by our booth at Broomfield Days and for reaching out! Although I did not speak to you myself, my assumption based on the information you provided is that they were referring to a product that uses a strain of the bacterium Bacillus thuringiensis. One of the product names is "grubGONE!"

Bacillus thuringiensis are used as a biocontrol and are not harmful to pollinators.

This product and other treatments for adults and larvae are discussed in this CSU Extension Japanese Beetle fact sheet.

I hope this is helpful! If I am off base on the product you discussed, perhaps it is another in that document that you'll recognize.
