CITY DISPOSES OF ABOUT 1,200 RATS - The
city has disposed of an estimated 1,200 rats in its new campaign.
Dr. Austin Getz, city sanitarian, today made that estimate, based on the
amount of warfarin bait which has been eaten from 54 bait stations placed
in downtown and 4th Ward areas. Dr. Getz estimates about one-third
of the rats killed fed at 4th Ward stations, the rest downtown, particularly
in the areas abutting the railroad right-of-way.
The estimated total of rats poisoned so
far is smaller than was anticipated, Dr. Getz says. This may not
mean that the rat population is smaller than was expected, however, he
said. Weather was stormy or cold the first couple weeks the stations
were out and this may have kept rats relatively inactive. Too, he
said, observation of stations in one area showed that it took several days
for the rats to become used to the stations (white painted self feeders
about 15x6x9 inches).
In the area observed, the rats left the
station untouched for several days although there was much rat activity
in the area surrounding it. then, the rats investigated and soon
were feeding full scale. The warfarin poison is mixed with table
quality oatmeal and cornmeal. The poison has no immediate effect
on the rat but several feedings produce a cumulative poisoning action that
is deadly.
The stations have openings 1½ inches
square so bait cannot be reached by dogs or cats. It would not be
attractive to them, anyway. Of the 54 stations in service about 15
or 20 are in the 4th Ward areas, the rest downtown. Dr. Getz says
they are moved occasionally when areas of new or greater rat activity are
noted. At first the stations were serviced every day. Now a
once-every-two-weeks schedule of service is used. Archie Schlarbaum,
the city's animal control officer, looks after the stations.
Dr. Getz says the stations will be kept
operative throughout the summer and that he hopes they will be kept as
a continuing city service. the annual cost hereafter, just for bait
and station replacements would not be great and would diminish as the long
term effect of the campaign is reached. |
