I do not want to spray insecticide. So I wonder how I can increase the
wasp population. Perhaps have a dirt mound every summer?

They seem to find sandy areas such as when a new
sidewalk or patio is put in. Don't kill them and there
will be more showing up each year. I think the shorter
list of birds would be what birds don't eat them.
