With a simple but sophisticated 3D print model, the maker “Overton Prints” offers a solution for gardeners who are struggling with an overpopulation of woodlice (also known as pillbugs) in their beds. The model is available free of charge on the Thingiverse platform and can be easily produced using standard FDM printers.
The aim of the project is not to kill the animals, but to remove them from particularly affected garden areas in a controlled manner. The trapped woodlice can be transferred to compost, for example, where they continue to contribute to the decomposition of organic materials. The trap does not rely on bait, but on the behavior of the animals, which prefer dark, damp and protected places. The design of the trap imitates precisely this microclimate.
The construction consists of four parts. A housing, the removable trap body, a lid and an optional cover for times without active use. The housing is buried flush with the ground and contains a small hole at the bottom to prevent water from collecting. The trap body itself also has a drainage opening. The insert can be easily removed for emptying without having to dig out the entire housing.
Placement plays a decisive role in success. According to experience reports, the best results are achieved along the edges of flower beds, in shady corners or generally in places where the animals gather anyway. The flat design ensures that the lid is as close to the ground as possible – which increases the hiding effect for the animals.
