An alkaline earth or alkaline earth metal phosphide-based hydrogen phosphide generating pest control agent with a moisture-permeable coating thereon for delaying the gas generation which is formed from moisture-pervious, solid, organic materials and which completely envelops the hydrogen phosphide generating composition. The moisture permeability of the coating is controlled to delay the onset of hydrogen phosphide generation for a desired period of several hours up to one month.
