Grass Carrier Wasps

Ever seen a weird mush of straw in your sliding glass door between the screen and the glass? Ever opened your door to have a bunch of dead grasshoppers fall on your head?  Find a sticky white substance stuck to the tracts?  You might have a grass carrier wasp on your hand. The green grasshoppers are tree crickets. Just remove the nest and if it returns, remove it again. The best way to get rid of them is to fix any cracks/gaps in the doors.
