Hello Here's some tricks you can try. For fungus gnats water infected plants with 1 once of 35% Hydrogen Peroxide to 5 gallons of water. The extra oxygen drowns the maggots of the gnats. For spider mites mix, Isopropanol alcohol 1 once to 1 quart of water, and a few drops of dish soap in a spray bottle. Tilt the plant please. The plant can get drunk, and look all wilty for a day or so if you get too much alcohol on their roots. The alcohol dries them out, and the soap gets in their lungs and drowns them. Good Luck. Chuck.
