Compositions, methods for forming compositions, and methods for using compositions for reducing tadpole shrimp populations in temporary pools using the hormone methyl farnesoate. Compositions can include a dry base having a bulk ingredient, a viscous additive having an oily compound, a saline solution, and preparation having an effective amount of phospholipid-encapsulated methyl farnesoate. The composition can be formed by combining the dry base and the viscous additive into a first mixture and adding all or a portion of the saline solution to form a crumbly consistency. Then, the methyl farnesoate preparation can be added. The composition may then be formed into a plurality of particles having shapes and sizes for consumption by the tadpole shrimp. In use, the particles may be dispensed prior to, or immediately after, the temporary pools are flooded with water. The particles may be formed such that they can withstand exposure to water for between about 4 to about 14 days.
