UV fluorescent blue honeybee swarm trap entrances - $20 (Summit/17)

UV reactive blue swarm trap disc entrances have been shown to attract more scout bees and catch more honeybee swarms than without.
There is an excellent article about this in the Sept 2022 issue of Bee Culture magazine.
I printed and used these on all my traps last year and caught 12 swarms during the season.
These are 3D printed from UV reactive (fluorescent) blue PETG filament for outdoor durability, selling 4 discs for $20, and will include a PDF on swarm trap building.
Local pickup available if you are in the Los Gatos/San Jose/Santa Cruz area, or I have them available online at https://squishymatter.
