Traps
The multiple-capture rat traps used in this study were
made of metal wire mesh and measured 50 × 20 × 20 cm.
The entrance tunnel was cone-shaped, narrowing to the
end with bent metal wires to prevent the captured rat from
escaping. One trap was installed in the centre of each side
of the TBS+TC, with its entrance facing an opening at the
base of the polyethylene sheet.
