(4) Anticoagulants come in many ready-to-use forms such as bait blocks,
pellets, toss packs, and paraffin formulations. These formulations require in mixing or
formulating and hence are timesaving devices.
(5) Baits formulated with grain products (for example, toss-it packs, ready-to-
use) may be a source of stored products pest infestation. Toss-it packs should not be
used where infestable subsistance items are stored because of possible stored
products pests infestations.
(6) The following precautions must be observed when mixing baits:
(a) Clearly label poisons and mixing equipment. Do not use mixing
equipment for other purposes. Lock up poisons and mixing equipment when not in use.
(b) Treat all poisons with respect. Avoid inhaling powders or getting
poisons on hands, clothes, or utensils from which they may reach the mouth.
(c) Always mix poisons in a well-ventilated place, particularly when
mixing dry ingredients.
(7) For second-generation anticoagulants such as Talon (Brodifacoum), Maki
(Bromadiolone), and Epibloc (alpha-chlorhydrin) numerous small baits (5 to 15 grams)
should be used at intervals of 7 days in places frequented by rodents. Baits should be
utilized in tamper-proof bait boxes addressed in paragraph e. below.
e. Bait Boxes. Bait boxes should be tamper-proof (where children or curious
people can't reach the baits) and protected from domestic animals. They should be
weather-resistant, unbreakable and should be nailed into place or secured in places
where people may move or tamper with them. Several commercial-type bait boxes are
available which fulfill these requirements. All bait boxes should have 2-inch openings.
Maintenance of continuity in the rodent control program is of paramount
importance. The following steps should be followed to ensure the complete eradication
a. Resurvey regularly.
b. Continue environmental sanitation.
c. Routinely inspect and repair rodent proofing.
d. Exterminate rodents as required.
