I just spray a lil on the plants mainly in early Veg. Your not gonna wanna spray on your buds, maybe around the bottom. Any Wal-Mart should have it in the garden section, you could probably order, but I'm not sure about shipping outta country. I haven't sprayed mine in awhile I'll probably spray the containers, not the plant, maybe a mist around the bottom. I had a fox late last season cut a plant exactly at the base. That's really the only predators besides the bugs and stuff.
