Does this completely eliminate fungus gnats instantly?

No, this is not an instant “one-spray” solution. It works by targeting both adult gnats and larvae over time. For best results, apply consistently over several days to break the life cycle and prevent reinfestation.

Is this safe for all houseplants?

Yes, the formula is designed to be safe for most houseplants, seedlings, and soil when used as directed. We recommend testing on a small area first, especially for delicate or sensitive plants.

How often should I use the spray?

For active infestations, apply daily or every few days depending on severity. Continued use helps eliminate larvae in the soil and prevents new adults from emerging, ensuring longer-term control.

Can I use this indoors without harming pets or people?

Yes, the eco-friendly formula is suitable for indoor use when applied as instructed. Avoid direct contact with pets and surfaces, and allow the spray to dry before letting pets near treated areas.

Why am I still seeing gnats after spraying?

Fungus gnats have a life cycle, so you may still see adults shortly after treatment. This is normal. Continued application targets larvae in the soil, which is key to fully resolving the infestation.
