Boric Acid Hornet Trap – Kill the Nest, Not Just the Wasps
Most traps only catch a few wasps. This one helps take out the whole colony.
This design uses a boric acid that worker wasps carry back to the nest, spreading it and reducing the population at the source.
Features:
Easy-entry ports to attract wasps
Protected bait chamber (less rain dilution)
Venting for better scent spread
Simple, modular print — easy to refill
How to use:
Fill with 1 teaspoon boric acid + 1 cup apple juice (or sugar water), and place near activity. That should make enough for 2 fillings.
Print instructions:
No supports needed
Just need enough walls to make it water tight (usually 3+)
Many thanks to @STL_Joe for the inspiration, I had some issues printing his design so I created this one to reduce the need to supports
Just saw CNC Kitchen's video on bumpmesh.com so I thought it would be fun to add a textured versions as well.
