Compositions having rodenticidal activity are disclosed which are constituted by a solution of a compound having anti-coagulant activity and which is an indane dione or a 4-hydroxycoumarin, preferably chlorophacinone, diphacinone, bromadiolone or coumachlor, in a glycol in admixture with a volatile co-solvent, preferably acetone or dichloromethane, which increases the solvent activity of the glycol for the anti-coagulant compound. The composition is stable and may be applied to solid or liquid baits or used to form trail poisons.

A food composition for poisoning a rodent, which comprises a rodent foodstuff which contains as an active rodenticidal agent, a lethal or sub-lethal quantity of a compound having the formula: ##STR1## wherein X is Cl, Br, F, or I; Y is H, Cl, Br, F, I, --SO.sub.3 H, SO.sub.3 Na, or --SO.sub.3 K; and R.sub.1 -R.sub.4 are each independently H, Cl, Br, F, I, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 alkoxyl, or C.sub.1 -C.sub.6 alkoxyalkyl or a hydroquinone analogue of the compound, and a method for controlling rodents using said composition.
Rodenticidal compositions comprising an anticoagulant type rodenticide in combination with a fluorosurfactant of the amphoteric, anionic or cationic type, optionally admixed with a cereal grain bait, and a method of killing rodents by oral administration of such compositions.
A composition and a method of using the same wherein said composition comprises a rodenticide and an additive selected from the group consisting of 1. polyoxyalkylated alkyl phenols; 2. sorbitan fatty acids and polyoxyalkylated derivatives thereof; 3. polyoxyalkylated fatty amines; 4. polyoxyalkylated branched or linear alcohols, diols or polyols; 5. polyoxyalkylated branched or linear mercaptans; 6. polyoxyalkylated esters; and 7. polyoxyalkylated amines. The composition may optionally include an organic solvent and/or a dye. The rodenticide may be selected from a wide host of compounds, including brodifacoum, bromadiolone, diphacinone, chlorodiphacinone, monofluoroacetatic acid, bromethalin, calciferol, flocoumafen, and salts of such compounds.
