Earwigs (pincher bugs) on our porch!!?

Those are some good ideas. If your deck gets wet from watering plants you want to get away form that. They like damp tight places. Under a flower pot or between moist boards is like a welcome mat. As long as those conditions persist, any that you get rid of will be replaced. They also don't like diatomaceous earth (from a pool supply) sprinkle it around they won't cross.
