Are Nyguard and Bifen IT safe for house plants?
If so how should I apply for fungus gnats
Answer:
Bifen IT is safe on house plants on the foliage. Nyguard is not labeled for this use. For fungus gnats you would be using as a soil drench to treat. The other option is to allow the soil to dry out completely as this will kill any larvae in the soil.
