Knock-Out Gnats™ Granules
A biological larvicide that kills fungus gnat larvae
- Thrice-weekly applications control gnat populations
- Great for houseplants or greenhouses

AE AK GU HI PR
Fungus gnats love to lay their eggs in humus-rich organic soil and potting media, especially in moderately warm temperatures-which often makes them a real problem if you grow lots of houseplants or have a greenhouse. With Knock-Out Gnat Granules, the larvae ingest the larvicide and die before they can harm your plants. Simply apply the granules to the soil, then water to help spread the larvicide. It won't help control adult gnats, but by making thrice-weekly applications, you can control the next wave of larvae. If larvae is present, they usually respond to Knock-Out Gnats™ treatment in 24 hours. Can be used on Vegetable plants, such as tomatoes, leafy and cole crops, cucumbers, peppers and eggplants.
- Season: both Spring & Fall
- Size: 4 Oz
