How do I apply Gnatrol WDG Biological Larvicide?

I inherited this from former greenhouse teacher & instructions are not on can.

Answer:

Per the label, To apply Gnatrol WDG Biological Larvicide, enforce the solution with adequate water as a soil drench. When all life stages are present (eggs, larva, adult), make weekly applications for 3 weeks at 13 to 26 ounce or 100 gallons. Gnatrol WDG only controls larva, applications must be made when larval stages are present. Please see the Label for complete application instructions.
