Dipping unrooted vegetative cuttings to reduce pest

One of the best ways to start off a new year in the greenhouse is to clean and sanitize benches, floors, and equipment. However, these efforts can feel futile when pest insects hitch a ride on unrooted cuttings and rooted liners. We know from prior research that any plant material entering the greenhouse is likely to have a small number of pests. These pests are difficult to detect and often possess some level of pesticide resistance. What if there were a way to suffocate any pest insects on the plant material coming into the greenhouse to have a better start?
