for your input. I would like to kill them...otherwise they will just move into something else. My preference is not to use insecticidal soap because earthworms live in my containers, too.
After I turn over a container to pull out the old soil, I start grabbing the earthworms, so they can be put back in the container. I am sure that all the organic matter in my containers is an insect invitation.
I think you came up with a good idea/solution to just spread the soil out on concrete in the sun. That is the easiest!
Many blessings for a safe, healthy, and happy year!
