Patent ID: 8557268

Claim:
A pest control method comprising: providing a pest control composition, said pest control composition comprising discrete plural particles, each of said discrete plural particles including a partially enzymatically hydrolyzed porous granular starch and a pest control agent absorbed therewithin; and one or more binder, and releasing said pest control agent into a pest control target area; and said pest control composition being in the form of discrete plural particles of a compressed mixture said binder included in an amount effective to provide said particles with a crush strength of at least 300 grams, wherein the crush strength is measured by selecting a sample particle and applying a force of compression at a speed of 1.0 mm/second and determining the force of compression at which the pellet cracks and breaks, the amounts of the partially hydrolyzed porous granular starch and the binder also effective to provide said particles with a release characteristic effective to release at least 50 percent of the pest control agent within 24 hours of the introduction of the pest control composition to a water column at 25° C.
