4.4.3 Moving nets
Single-pole flicking
This method, which requires two people in normal use, can be employed in any area with some success,
including from bridges over canals and rivers (Figure. In this case, am or m net is lowered over the bridge, being fixed to the parapet atone end by the top shelf string and having a weight tied to the bottom shelf string. The other end has a pole, to which the net is firmly fixed by elastic bands on both top and bottom shelf strings. This stops the net sliding off the pole. The pole is held vertically down by one operator,
and approaching bats can be caught by moving the pole quickly upwards through an arc so as to encircle them. Once a bat is netted, the tension on the netting should not be altered, especially by stretching it, and the second person should retrieve any bats gently.
Illuminating the catching area from the side with a strong spotlight makes catching easier. Bats may soon be frightened away, so periodically remove the net or move to another bridge.
