Fill the little tray at the bottom with sugary beer, and you will catch and kill hundreds of snails, slugs, and pill bugs (roly poly).
Put it in anywhere, and the slanted edges will be easy to climb for the bugs!. just snap the lid on, and you're good to go!
The little removable roof makes it easy to fill, clean, etc, while also keeping rain out of the beer.
Print in PETG or ABS to keep it from deteriorating in weather.
