Not this year. When I opened the packet of bean seeds that I had saved last fall, I found all of these little holes in my beans. Turns out the culprit is the bean weevil, Acanthoscelides obtectus.
Their larvae make swiss cheese out of dried beans.
While they can be a pest in the garden apparently they usually are a problem in stored beans. And it turns out they love our mild California winters which allow them to reproduce year round. I also looked them up on the handy dandy University of California Integrated Pest Management site. Turns out not having dried beans around is the best way to control them. I probably am storing too many seeds in my garage. This fall I’m going to use glass jars instead of paper envelopes and see if that keeps some of the critters out.
