The Asian hornet is an invasive species that poses a threat to biodiversity in Europe. The hornet is larger and more aggressive than the European wasp and can attack beehives, causing them to disappear.

An effective way to combat the Asian hornet is to place trap traps. These traps are specifically designed to attract the queens of the hornet. The queens are needed for the reproduction of the species, so if they are caught, the spread of the hornet is slowed down.

3D-printed traps are a relatively new development. These traps are often cheaper and easier to make than traditional traps. In addition, they are often more durable because they are made of stronger materials.

There are several 3D models of Asian hornet traps available. Most models have an opening of about 8.5 mm. This opening is large enough for the queens of the Asian hornet, but too small for the queens of the European wasp.

If you want to make a 3D-printed Asian hornet trap, you can download a ready-made model from the internet or design a model yourself. You can then print the trap with a 3D printer.

Here are some tips for placing a 3D-printed Asian hornet trap:

• Place the trap in a sheltered spot where it will not be disturbed by people or animals.
• Place the trap at a height of about 1 meter.
• Fill the trap with an attractive lure, such as honey or bait.

By placing a 3D-printed Asian hornet trap, you can help to combat this invasive species.
