Researching Fly Trappers

Wizened elf researched the fly trappers as well as he could. They were wreaking havoc and destruction in the deep north wood. How do you get them to stop? He asked, looking them up at will. Unfortunately, you have to push them out a bricked over window sill. We don’t have those wizened elf lamented, now worried. He heard the mice below, some of them now had scurried. There has to be another way, he said, reaching for another book. He has no great solution, I guess, I say, giving him a sad look.
