Grass Carrying Wasps

Grass carrying wasps, A solitary wasp, packs a small cavity such as around a window or storm window frame with grass, stings a grasshopper or other bug and lays her egg inside. Her hatched egg feeds on the insect and grows up to build a pupae casing in the grass nest created by its mother. Next spring the pupa will emerge and start the process again. Not structure infesting, does not sting, never even noticed by customers usually with the exception of the grass in the windows.
