Rodenticidal imidazo-pyridines

A method for reducing or eradicating a rodent population which comprises supplying to a locus frequented by said population an effective amount of an active agent which comprises at least one compound selected from the group consisting of those compounds of the formula ##SPC6##

• and the salts, with non-toxic cations, of those compounds wherein R.sup.2 represents hydrogen or hydroxy;
• wherein R.sup.1 represents
• 1. --CF.sub.3,
• 2. --cf.sub.2 cl, or
• 3. --CF.sub.2 H;
• n represents an integer from 0 to 3;
• q represents 0 or 1;
• each of n and p represents 0 or 1, subject to the limitations (1) that where n is 1, the loweralkyl group so specified is at the 6-position;
• and (2) that the sum of m, n, and p is an integer from 1 to 3;
• R.sup.2 represents
• 1. hydrogen,
• 2. hydroxy, or
• 3. OR.sup.3 where R.sup.3 represents
• a. alkyl of C.sub.1 -C.sub.8,
• b. (loweralkoxy of C.sub.1 -C.sub.4)methyl,
• c. alkenyl of C.sub.2 -C.sub.8,
• d. cycloalkyl of C.sub.5 -C.sub.6,
• e. benzyl,
• f. phenethyl,
• g. alkanoyl of C.sub.2 -C.sub.18,
• h. alkenoyl of C.sub.3 -C.sub.18,
• i. carbamoyl of the formula ##EQU3## wherein one R.sup.4 represents phenyl, loweralkyl of C.sub.1 -C.sub.4, or loweralkenyl of C.sub.2 -C.sub.4, and the other R.sup.4 represents hydrogen, loweralkyl of C.sub.1 -C.sub.4, or loweralkenyl of C.sub.2 -C.sub.4, subject to the limitation that both R.sup.4 moieties taken together do not contain more than six carbon atoms;
• j. radical of the formula ##EQU4## loweralkyl of C.sub.1 -C.sub.4 or ##SPC7##
• k. radical of the formula ##SPC8##
• wherein R.sup.5 represents methylene, ethylene, or vinylene, and n represents 0 or 1,
• l. --SO.sub.2 - R.sup.6 wherein R.sup.6 is loweralkyl as above defined, cycloalkyl of C.sub.5 -C.sub.6, phenyl, benzyl, or phenyl bearing from 1-3 substituents, each of which is independently amino, nitro chloro, methyl, or methoxy;
• and R.sup.7 represents
• 1. perfluoroalkyl of C.sub.1 -C.sub.7,
• 2. --cf.sub.2 h, or
• 3. --CF.sub.2 --CF.sub.2 H.
