I was clearing out files and discovered article in garden folder suggesting sprinkling cornmeal to get rid of earwigs. Worth a try, costs very little and nontoxic.
Damn! My back yard is against a high wall that separates it from adjacent street. There are blackberries growing over wall that I pick. Good eating. Today all the brambles were gone! City apparently had landscapers cut them back. They will grow again, blackberries always do, but could be a year before I have berries.
