I'm in the same camp as Zuzu when it comes to wood mulches and the earwig issue.
In addition, I quit using redwood mulch after one application because it just attracted termites. Contrary to popular belief, termites DO eat redwood and cedar...here, anyway.
When "going green" became the rage and cities here started offering free "compost", I went and got some...like a full truck load. Big mistake. It was horrible stuff...full of glass, wire, batteries, etc.
I didn't know that until I got it home.
