A method of formulating insecticides and other chemicals for controlled release. Microscopic spheres containing the chemical are formed from a polymer with various degrees of cross-linking, thickness of the capsule wall, and sphere size, thereby regulating release rates of the chemicals. This usually produces a longer-lasting method of application, reduced volatility, and lower mammalian toxicity. Sometimes bees are at greater risk, however, due to their tendency to confuse the spheres with pollen grains.
