A rodenticide composition is described along with a method for using the same to exterminate rodents. The composition features a mixture of a dehydrant for causing dehydration in a rodent, a water-absorbent, hygromorphic carrier for absorbing water and expanding after consumption by the rodent, and a flavoring composition. The carrier can be a source of cellulose or a non-cellulosic material. After consumption of the composition by a rodent, the dehydrant and carrier cause the rodent to experience dehydration. The rodenticide composition may also include an irritant that causes digestive stress to the rodent, which further stresses and dehydrates the rodent. Once the rodenticide composition is prepared, it may be placed in areas frequented by or infested with rodents so as to kill the rodents once they consume the composition. One or more flavorings, coloring agents, and weather resistant materials may also be added to the composition.

A breakable nonflowing gel bait composition that includes water in a range of about 40% to about 99% by weight of the composition, a toxicant in a range of about 0.0001% to about 25% by weight of the composition, one or more attractants in a combined range from about 1% to about 49% by weight of the composition, a gelling agent in a range of about 0.001% to about 15% by weight of the composition, and wherein the breakable nonflowing gel bait composition is a breakable nonflowing gel.

Compositions attractive to rodents, such as mice and rats, include one or more of androstenone, testosterone, progesterone, and estrogen. The compositions can further include at least one of a lethal agent or a chemosterilant. The androstenone, testosterone, progesterone, and estrogen are isolated, purified, and/or synthetic. Devices, traps, and methods of using the compositions are also disclosed.

The present invention provides compositions for delivering an active agent to an animal, comprising an active agent, a first coating, a second coating and a third coating. The active agent is coated with the first coating, the first coating is coated with the second coating, and the second coating is coated with the third coating. The active agent is in contact with the first coating, not the second or third coating. The first coating separates the active agent from the second coating while the second coating separates the first and third coatings. The first, second and third coatings are different from each other. Also provided are methods for making and using the compositions.

Disclosed is a dextrorotatory enantiomer of a configurational stereoisomer of difethialone, named hetero-stereoisomer, the formula of which is 3-(4-bromobiphenyl-4-yl)-1-(4-hydroxythiocoumarin-3-yl)-1,2,3,4-tetrahydronaphthalene, in which carbons 1 and 3 of the 1,2,3,4-tetrahydronaphthalene group have different absolute configurations.
