    I guess 3D printers are very common these days! I wonder if a funnel would work, or is the hole too big?

    a funnel would probably work well for larger house flys and wasps but the hole could be too large for fruit flies - best to experiment and see what works!

    I've used cider vinegar to great effect. A paper funnel works fine as long as you tape the edges of the jar to it and don't get the liquid on it. Thanks for the instructable!
