Kirchhoff’s Margaret Roberts Biological Mosquito Insecticide

A water dispersible granular biological larvicide for the control of mosquito larvae and fungus gnat larvae in the home garden.  It will not control adult mosquitos or adult fungus gnats.  It effectively controls the larval stage.  Once ingested, it disintegrates the wall of the digestive tract, feeding stops and death occurs within 24 hours.
