A good organic earwig trap is a hollow tube (such as a hollow bamboo
shoot or the cardboard spacer on the bottom of clothes hangers.
Earwigs hide out in the tube and can be captured/destroyed by shaking
them out of the tube into some soapy water.  This tip came from Rodale's
_Encyclopedia_of_Organic_Gardening_.
 
Why do they call it an earwig anyway?  It has no ears, it has no wig,
what's earwig all about?
