The NHBS Harp Trap is an exciting new product that has been designed and built by NHBS, making it the only harp trap that is commercially produced in Europe. Harp traps provide a less stressful alternative to mist nets for capturing bats when surveying, and this trap has been carefully designed in collaboration with harp trap experts to ensure the safety of bats and improve catch efficiency. The trap is available as a three-bank trap as standard, but please contact our Workshop Team to discuss your requirements if you would like a bespoke two or four bank trap, or if you would like a trap that has the ability to be suspended from a support.

The trap includes innovative design features such as a winding line carrier, which makes setting up and disassembly very quick and easy, with features that prevent line tangling. The whole trap collapses down effortlessly after a catching session, and the catch bag wraps around the metal elements and is held in place with the attached material straps so that it can be neatly stored and carried in its bag. We recommend that the trap is put together by two people and this takes about 6 – 7 minutes. The trap has extending legs, so the height of the catching area can be adjusted vertically. This can help with uneven ground, slopes or to bring the catch bag nearer a raised cave entrance.

The harp trap is composed of lightweight aluminium line carriers and legs struts combined with sturdy and durable marine grade stainless-steel supports. The catch bag is made from green cotton canvas that is water resistant (oil coated) and breathable, and it includes heavy duty clear plastic baffles to prevent the bats from escaping. There is an extension under the catch bag that stops bats from flying underneath the trap and wraps around the string assembly for protection during storage. There is also the option to anchor the harp trap with guy ropes if the situation in which it is being used demands this.

The trap has a catch area of about 4.05m2 and is 180cm long. The catch bag is approximately 60cm deep and at its entrance is about 44cm wide. The trap weighs 15kg.

The NHBS Harp Trap includes a fully strung and tensioned three bank trap, the carry bag, guy ropes and pegs, spare restringing line, and instruction sheets.

Harp traps will only be sold to people licensed to use them. If you are licensed to catch bats, please supply a copy of your NE, NRW or SNH licence. If you are purchasing from overseas, please contact us for requirements.
