Food is essential for outdoor camping; during breaks, picnics with the gentle breeze and delicious meals are often spoiled by persistent insects.

Traditional picnic boxes are bulky and inconvenient for hiking. Plastic bags can offer some protection against larger flying insects and crawling bugs,

but they still leave you vulnerable to swarms of ants and tiny crawlers that seem impossible to keep out!

This is where China’s ancient invention—the “ant‑killing trap”—comes into play.

By leveraging biological habits,

we recognize that for most terrestrial insects, water represents a hazardous environment best avoided, only entering it under extreme necessity.

Using water as a barrier, we block pathways, isolate disturbances, and allow outdoor dining experiences to remain carefree and enjoyable.

Since the load-bearing capacity of 3D-printed objects depends on the material used,

I designed the structure with an open central cavity

so that the overall load-bearing strength relies entirely on the supporting ropes.

Therefore, after threading the ropes through, be sure to seal the central opening tightly

This prevents insects from climbing directly underneath via the opening
