re: What to do about dirt daubers?

works for us on the ceiling, but where it nmeets the hardy board....yea they just build the damn things there instead

Get a wooden carpenter bee trap that has a glass jar on the bottom. I was at a garden nursery today and they had about 10 of them hanging from their front covered porch. They were all almost full of mostly dirt daubers and wasps and some bees. There were hundreds of dead wasps, dirt daubers and carpenter bees in the glass jars. I think the traps are basically just a small square wooden box with a mason jar attached to the bottom. A simple hole the size of a carpenter bee hole is drilled in the side and bees, wasps and dirt daubers are attracted to the hole. I'm not sure what kills them once they are in the box. It was pretty impressive.
