Kate I thought you could not kill them either. I moved all my semps from the old house. I even went back to see if any was still hiding. I think if there were any left the landscaper took them out.
The realtor told me to downsize the gardens so I pretty much emptied most of the gardens and made them cookie cutter a few bushes and grass.
I have a cactus succulent garden so nothing is hiding. They died.
