PC11 TRANSFORMER 150V STEP DOWN T-2150 (BLACK)
Connect 2 aluminium wires/ stainless steel cables to the positive and negative ends of the transformer respectively at the entrance hole. The output of the transformer will shock the intruders to bird house such as lizard, bat, pigeon, owl, crow etc whichever steps on the positive and negative output wire/cable from the transformer.
It will not affect the swiftlets as they will fly into bird house directly without touching the edge of the entrance hole.
