4. Rodent Control<br />
The <strong>control</strong> of rodents requires a combination<br />
of knowledge, effort and tools. As in<br />
the case with insects, the primary effort<br />
should be directed to cleanliness. Rodents<br />
require food and shelter. Therefore the removal<br />
of weeds and debris in the yards<br />
surrounding awarehouse or storage facility<br />
is important. Broken bags, poorly stacked<br />
equipment and general untidiness within a<br />
building isan invitation to rodents. Doors,<br />
windows and other openings into a building<br />
should be screened or kept closed, espeinch<br />
mesh should<br />
cially at night. Wire of 1/2<br />
keep rats out; 14 inch isrequired for mice.<br />
Poison baits and tracking powders may be<br />
used both within a building as well as<br />
around the exterior. An anti-coagulant type<br />
poison is relatively safe to use since it would<br />
require an extremely lare quantity to injure<br />
a human. The purpose of a tracking powder<br />
isto place it in an area frequented by<br />
rodents. They get it on their feet and body,<br />
lick it off and take into their system through<br />
the mouth. The same formulations used to<br />
fumigate grain and food would also be<br />
effective against rodents. Actually rodents<br />
are killed with a lower concentration of a<br />
fumigant than is required to kill insects.<br />
Traps may be used in a rodent <strong>control</strong> program.<br />
However because of the problem of<br />
servicing and pilferage, traps may not be<br />
practical. Cats will catch a few rodents but<br />
like the traps, they are usually not of much<br />
value.<br />
Rodent <strong>control</strong> is a combination of five<br />
efforts:<br />
1. Cleanliness<br />
2. Structure design<br />
3. Poison baits and tracking powders<br />
4. Trapping<br />
4. Fumigation<br />
5. Sampling Techniques<br />
When grain or any dry food product is<br />
stored in the open, it issubject to deterioration<br />
much more rapidly than when it can<br />
be protected under a roof. The sunshine,<br />
rain, insects and rodents all may contribute<br />
to spoilage and <strong>control</strong> or prevention is<br />
very difficult.<br />
It isdifficult to sample to any depth in large<br />
piles of bagged material. However, it should<br />
be examined frequently to determine if a<br />
problem does exist.<br />
During the demonstration at the Transcon<br />
warehouse, the seminar staff was assisted<br />
by a representative from the National Grains<br />
Authority of the Philippine Government.
