asian hornet trap - piege frelon asiatique

Selective Asian hornet trap.

This requires a "milk bottle" type jar.

The two 9 mm entrances allow trapping Asian hornets but prevent entry by European hornets or butterflies.

Various exits are provided on the sides and under the model (6.5 mm round openings) allowing smaller insects to escape and water to drain; the model can be placed or hung.

For optimal effectiveness, use a mixture of 1/3 beer – 1/3 white wine – 1/3 syrup in the jar.

A hole is provided for securing the jar with a branch, screw, or other means.

A printable jar is also included to allow scaling the model up or down.

The file is royalty-free and can be modified at will; feedback is appreciated.
