For the past four years it has been very difficult to grow Glandulicactus here in Wisconsin because they end up being eaten by fly maggots. Now this summer for the first time all of these plants have survived and grown very well. The change is that I've been applying a product called Mosquito Beater by Bonide to the soil with Glandulicactus plants. The Bacillus thuringiensis subsp. israelensis is a microbe that lives on Mosquito larva and appears to do in soil fly larva too. I will have to change my Rock Garden Cold Hardy Cactus page to say that it is possible to grow Glandulicactus and Sclerocactus plants in places like Wisconsin if it is done with the help of Bacillus thuringiensis subsp. israelensi, and many thanks to the scientist who refined this microbe.
