Fungus Gnat FAQ

How long does Gnatrol WDG take to work?

Gnatrol kills larvae within 24–48 hours.
Visible results typically appear in 7–10 days as adult gnats die off.

Why do I need to make applications every 5-7 days?

Gnatrol only kills larvae while they are actively feeding, and each application remains effective for a limited time. Reapplying every 5–7 days ensures newly hatched larvae are targeted, breaking the life cycle over 2–3 weeks.

Is it safe to use Gnatrol WDG indoors around people and pets?

Safe for indoor use  •  Pet friendly 
The naturally occurring soil bacterium (BTI) specifically targets fungus gnat larvae.

BTI is harmless to people, pets, and plants. 

Should I continue to use Gnatrol after Fungus Gnats are gone?

Yes — small monthly applications help prevent future infestations, especially if you bring in new plants, new soil, or move plants between indoor and outdoor environments.
