Or hey....non chemical way to remove..........portable vacuum cleaner......suck em up.
We used vacuum cleaners alot when we needed to remove problem pests but the situation dictated no insecticides. You get very good grasshopper sucking that critter on the fly.
.
best time to do that.
at first light or after dark. . All wasps, hornets, and bees are very photo sensitive and quit flying when its dark. I used to tease the thousands we had in cages in a lit room with no windows. Flip the light switch off and the i sect would hit the stainless steel cage floor and it sounded like hail hitting a tin roof.
flip the switch back on and it was a roar of instant buzz......
