UPDATE: I've designed Version 2: changes;-: Added a lip on the inside to prevent to much scent escaping trough the sides of the lid.-: enlaged entranvce, some wasps came back out because they didn't go all the way trough.This trap lid fits on a standard jar (diam 60). We have a lot of 'hac applesauce' laying around so it does work neatly!!Fill with sweet beverage, some honey or sugar and a drop of detergent.Print with no infill and very thick shel / outer perimeter to prevent hopping/threading.
