These wasps are often very colorful, achieving colors from metallic blue, black and green to typical yellow and black. They love cedar shake roofs and will be seen flying about looking for tidbits of food. On a summer day I have seen many hundreds swarming on a cedar shake roof. Probably few of them lived there but they will travel some distance for a meal. We can treat a roof with several products that are environmentally safe that will repel them.
Control is the only thing possible here.

A large unique insect, commonly found in ground nests and under slabs of concrete and in fairly commonly under mobile homes where they get into the insulation beneath the structure. Nests commonly contain a hundred bees or so.
