    Abstract

    The test methods used in this rodent control program, which can be tried by others, are unique in being exceptionally safe to people and to nontarget animals and very saving of bait material, which is important to many countries. Bait stations (boxes) are used. For safety and economic reasons, no poison bait is put in the bait stations until a spoonful (5 g) of whole rice (Step 1) has first been taken from the station by a rodent. Next, if many rats are present, 25 g of a prebait (Step 2) is put in the bait station. When all of the prebait is eaten, an acute rodenticide bait, in our tests 5 g of 0.5 percent RH 787 (Vacor), is added as Step 3. That is followed by Step 4, 25 g of anticoagulant bait. When toxic bait is no longer being eaten (because all the rodents are controlled), a spoonful of rice (Step 1), which deteriorates far less rapidly than ready-made baits and is safer, is put in the station and left until a new rodent appears. This paper also describes precontrol and postcontrol census methods, acceptance tests of bait material and of the toxic bait used, a method for determining the presence of survivors, and tests to distinguish new invaders from individuals that have become shy of the bait or the toxicant or both. Since a successful control program depends on an effective organizational structure, a Korean example is given to show how complex such a structure can be.
