This is easily one of the most novel uses of a 3D printer in the last several months. Apparently cabbage white butterfly females won’t lay eggs near what appear to be other cabbage white butterflys. Vik’s solution was to print a white plastic butterfly, add two black spots with a marker, and stick near his plants.
A printed pesticide with no harmful side effects, no lasting chemicals, and reusable year after year! That it works by trickery is just an added bonus.
Are there any other insects or garden pests that could be deterred in a similar way?
