The number of pre-bait takes was practically the same as in
the first maintenance treatment.
(2) 10% Test Baiting (1950-5I)
As previously, the Borough was divided into five sections,
and a test baiting of 10% of the soil-sewer manholes was carried
out during the month of September The test shewed a 7% increase
in the number of bait takes as compared with the previous year's
10% test
The results achieved were as under:-
| District | Number of manholes baited | Complete bait takes | Partial bait takes | Baits not taken |
|---|---|---|---|---|
| A | 22 | 10 | 1 | 11 |
| B | 25 | - | - | 25 |
| C | 53 | 11 | 1 | 41 |
| D | 69 | 14 | 7 | 48 |
| E | 46 | 16 | 4 | 26 |
| Total | 215 | 51 | 13 | 151 |
First Maintenance Treatment (1950-51)
The treatment was completed on the 1st November 1950
Prebaiting with damped sausage rusks was carried out on
two consecutive days, and the same bait base with 2½% Zinc
Phosphide added was laid on the third day- District B which
shewed no takes in the 10% test was not baited The other
four Districts shewed a substantial increase in the number
of prebait takes as compared with the previous treatments.
The known kill was very satisfactory and a decrease in the
number of takes is anticipated in the treatment which will
be commenced in March 1951
The following is a tabulated summary of the results achieved:-
| District | No. of manholes prebaited | Complete pre-bait takes | Partial pre-bait takes | Percentage of takes (C & P.T.) | No. of man holes poison baited |
|---|---|---|---|---|---|
| A | 56 | 23 | 4 | 48.2 | 27 |
| C | 52 | 26 | 7 | 63.4 | 35 |
| D | 106 | 30 | 20 | 47.1 | 59 |
