ants

In my sand bed I have lots of ant lions. That keeps the ant problem down to
a minimum! I have not watched for wasps... but they sound cool. The ant
lion pits make it look a like a lunar landscape.

As an aside, in my previous garden I had a sand bed that was wonderful for
growing some of the fussier alpines. Ants were never a problem, but
burrowing wasps loved it. There were at least three different kinds that
excavated long tunnels, often under plants. Fill then in, they come right
back. Losses were minor, however, and they were fun to watch.
