Abstract: An orally ingestible contraceptive low dose gossypol composition for rodents such as mice, rats and members of the order Rodentia is provided. The contraceptive composition comprises 0.0005 to 0.0045 wt. % of gossypol and a carrier. The carrier includes a bulk feed component. The bait or soft bait may be encased in a casing such as a collagen casing. Also provided is a method for contraception of rodents comprising administering the low dose-gossypol composition by making the contraceptive available for feeding the target animal.

Abstract: A liquid dispenser is described, having a tank configured to deliver and present a liquid in a drink basin within a tray base. The liquid may be a liquid bait for population control of small animals. To reduce evaporation and liquid waste, the tray base may be partially covered by a tray top. A spill basin may surround the drink basin, and may be configured so that tilting or inverting the liquid dispenser drains a liquid from the spill basin and drink basin back into the tank.

Abstract: Provided are compositions and methods for reducing the reproductive capacity of mammals. The compositions and methods involve the use and administration of (a) a diterpenoid epoxide comprising a triptolide skeleton and which causes ovarian follicle depletion in female mammals and (b) an organic diepoxide which causes ovarian follicle depletion in female mammals.

Abstract: A bait insert including a tank filled with a liquid bait having a discharge port, a tray top having an engagement port, and a drinking area, wherein the engagement port engages with the discharge port of the tank, and a tray base sealed to the tray top, wherein the tray base includes a plurality of troughs forming an internal flow paths for the liquid bait to flow from the tank to drinking area of the tray top. Further in one embodiment, a bait insert with a spiked tray base having a spike integral to the spiked tray base configured to pierce a foil of a sealed tank is described.
