I put a strong dose of Microbe Lift (1/2 ml in a gallon of water) and poured about 1/2 quart on each gallon pot. This morning I have only seen 2 adult gnats as I stirred up the soil on the tops of the pots. Before application there were probably 40-50 adults. Would the microbe lift kill the adults? Or drive them out of the room? Any one have experience with this?
