How Gnatrol WDG Works

Gnatrol WDG targets fungus gnat larvae in soil, stopping infestations at the source.

Step 1:
Mix Gnatrol WDG with water

​

Step 2:
Apply to moist soil

​

Step 3:
Repeat every 5–7 days for 2–3 weeks

Stop the infestation before it spreads

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.

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?

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

Safe for indoor use  •  Pet friendly 

BTI specifically targets fungus gnat larvae and does not harm people, pets, or plants.

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

Yes — monthly use helps keep fungus gnats from coming back.
Ideal when adding new plants, fresh soil, or moving plants between indoor and outdoor environments.

Will water with Gnatrol mixed in it be good for a long time?
