Question From: PENNSYLVANIA
Q: are nematodes good to kill fungus gnat larvae? I have hot pepper seedlings in a grow room under light.
A: There are several products that will do the job more quickly, are easy to find and probably less expensive. Neem oil is non toxic and safe to use on edibles. Mosquito Bits from Summit are also effective. To prevent infestation cover the surface of the soil with a layer of sharp sand. Best And Happy Yardening, Nancy
