I think you need a potato gun that shoots around corners.. Basically here is the design
A "Tank" (This is a length of like 5 or 6 inch PVC pipe capped with a tire fitting and a pressure gauge so you do not blow it up in your face, coming out of that is a good size length of pipe with a quarter turn valve (Instant open valves are better but harder to make) and from there we continue up to an elbow and perhaps a bit of smaller pipe.
Aim it under the awning and FIRE. Blast them nests to finders.
Oh, you just fire Air, no potato needed.
