Q: Where can I get some of the tansy flea beetles ? We used these many years ago and they did an incredible job. I do have some of the cinnabar larva present but they never start working early enough to prevent the plants from going to seed. The neighboring property has an enormous tansy crop and I am losing ground to this plant in my pasture.
