Abstract: A soil or other ground cover is treated for termite or other pest control by dispersing in the soil or on the ground, a toxic insecticide in an active available state and a toxic insecticide in an initially unavailable state and timed to be released before complete dissipation of the immediately available insecticide. The initially unavailable insecticide is enveloped in a container made of a material either in whole, in part attractive to and edible by the pest to release the insecticide when the container or plug is eaten by the pest. Combined with the insecticide is any odoriferous material which will signal the presence of termites by its distinctive odor. A soil coloring agent can be used also or in addition to provide a visual signal. The odor producing agent can be used alone.

Abstract: Soil is treated for termite or like control by dispersing in the soil a termite toxic insecticide in an active available state and a termite toxic insecticide in an initially unavailable state and timed to be released before complete dissipation of the immediately available insecticide. The initially unavailable insecticide is enveloped in a container made of a material either in whole or in part attractive to and edible by the termites, to release the insecticide when the container or plug is eaten by the termites.
