If you are seeing hornets coming in and out through cracks in the retaining wall, then a great product to use would be Tempo 1% Dust. You should apply the Tempo 1% Dust with a duster such as the B&G Bulb Duster 1150 and direct the dust into the cracks in the wall where you are seeing the insects enter and exit. You may also want to have Wasp Freeze on hand for quick knockdown of flying insects in the area.
