Yes, the Recycled Wasp Catcher works on all varities of Wasp including Paper or Umbrella Wasps.

No this product only works on Wasps.

With Wasps it's not really about area coverage but territories. You want to hang one wherever you see them congregating around your yard. If you have a small to medium yard one should be enough unless you notice them gathering in more than one spot. In a larger yard you may need 2 or more. I would start with one and add another if you still notice a lot of wasps hanging around.
