These traps, combined with our pitfall trap, are in use for the Swiss Biodiversity Monitoring (BDM-CH) in a project that employs rapid biodiversity assessment methods to comparably measure species diversity.

People interested in using this trap may contact us directly. The costs for material and manufacturing one trap amount to CHF 150.-

A few images should clarify the design and functioning of the trap. An explicit assembly instruction (5.8 MB pdf) can be found here: KF_Assembly_instruction.pdf
