(3) Treatment No, 21 - First Maintenance Treatment (1956-1957)
This treatment was confined to the sections known to have
been infested during the previous maintenance treatment together
with sections proved to he infested by the annual 10% test, and
operations were completed on the 29th September, 1956.
Prebalting with damped sausage rusks with 0.25% of paranltrophenol
added as a bait preservative was carried out on the
first and fifth days, and the same bait base with 2½% Zinc
Phosphide added was laid on the tenth day. This extended method
of treatment proved tobe most satisfactory, and shewed a higher
percentage of complete bait takes than in several of the previous
treatments. Use of paranltrophenol will be made in all future
treatments, as it was found that no moulds formed on the baits
even after being left ten days in the sewer manholes.
The following is a tabulated summary of the results achieved:-
| A | B | C | D | E | Total | |
|---|---|---|---|---|---|---|
| Number of manholes prebaited | 62 | Not baited | 90 | 87 | 77 | 316 |
| Complete prebalt takes | 6 | 27 | 34 | 19 | 86 | |
| Partial prebalt takes | 3 | 19 | 25 | 3 | 50 | |
| Percentage of takes (C. & P.) | 14.5 | 51.1 | 67.8 | 28.5 | 43.0 | |
| Number of manholes poison | ||||||
| baited | 12 | 68 | 65 | 29 | 174 |
The number of prebait takes shows an increase of 9.8% on
the previous maintenance treatment.
N.B. It was not necessary to bait Section B since there were
no bait takes during the 10% Test Baiting Treatment.
