I would guess that the zip ties look like and act like a branch in the way. It sounds efffective, they can't really get past them if they are in the right place.
Usually waving my hands around would get them to back off a bit, but occasionally they would plow into my helmet, and then flutter off somewhere. I think a few of them almost knocked themselves out.
