4.2.1 Fumigation against rodents is normally done
at dosages and periods of exposure much less than those required for
insect control. It follows that an insect fumigation also controls
rodents in areas that are treated. However, rodent control often requires
fumigation of accommodation and working spaces that may not normally
be treated for insect control.
4.2.2 Fumigation against rodents alone should
be undertaken in port and ventilation completed in port. The precautions
in 3.1.4 should be observed.
4.2.3 Methods involving fumigation or the use
of acute poisons should be employed only by qualified personnel of
pest control servicing firms or appropriate authorities (e.g., Port
Health Authorities). Baits containing acute poisons should be collected
and disposed of by such personnel when the treatment is completed.
Chronic poisons should be used strictly in accordance with the manufacturer's
instructions contained on the label or on the package itself.
