For the past four years continuous baiting of manholes has been
undertaken by a permanent rodent control gang, and after some 3,000
manholes had been baited three times over a period slightly longer than
a year a complete pre-baiting and poisoning control was exercised to
ascertain the result.
Under the old system of undertaking rodent control twice a year
the position was becoming static and over one-quarter of poison takes
were being recorded from the number of manholes baited. The prebait
and poison check which was undertaken in 1962 showed quite encouraging
results, recording a total of poison takes of considerably less
than a quarter.
Continuous baiting has once again been undertaken, but no
further pre-baiting test has been carried out.
