[Daffodil]

The poor wasps! All they are doing is looking for wood to make wood-pulp to make their nests. The tree house is perfect. They simply want to walk up and down chewing off a layer of wood pulp. By the way... how many people are aware that wasps kill and eat many other predators that ruin our gardens ? I am a wasp fan!
By the way, if you ignore them, they really are no trouble at all. Honest!
