I cut the very tip of the handle off of one of my dried long neck gourds from last year and it has been sitting next to the tomatoes for about a week. This morning I grabbed it to use as a watering can to water in a new transplant because my watering can was hidden by the kids. As I plunged it into a barrel of rain water to fill it up, HUNDREDS of earwigs came scurrying out! Most of them drown in the barrel. Needless to say, I'll be leaving it out and filling it with water daily now.
There were lots of juveniles and adults in there so I am assuming they were breeding in there. I know it's just a drop in the bucket, but who can complain about getting rid of hundreds of the buggers at one time, and all the potential offspring they would have made?
