The STV Zero In Gnat Barrier 2.5L is designed for indoor gardeners looking to protect their houseplants from fungus gnat infestations without the use of harsh chemicals. These non-toxic granules act as a physical and biological barrier that disrupts the pest's lifecycle, providing a decorative way to improve plant health and soil moisture retention. While highly effective at preventing larvae development, it requires consistent application to ensure full coverage of the soil surface to maintain its protective barrier.

Yes, the granules are non-toxic and formulated for safe use in homes with pets and children.
This product is designed for indoor houseplants. While it may work outdoors, weather conditions like wind and rain will likely displace the granules quickly.
Apply a layer sufficient to fully obscure the soil surface, ensuring no potting mix remains exposed.
You can mix them into the old soil or remove them before repotting, but fresh granules should be applied to the surface after the new plant is settled.
The barrier primarily targets the lifecycle by preventing larvae development and stopping egg-laying; it is not intended to be a spray-on insecticide for flying adults.
Ensure that the entire surface of the soil is covered; even small gaps can allow adults to reach the soil.
Use a watering can with a fine rose attachment or water from the base of the plant if the pot allows to prevent surface disruption.
Application is straightforward: simply sprinkle the granules until you achieve a consistent layer that covers the soil of your houseplant. It is compatible with all standard indoor potting mixes, including those used for succulents and tropical foliage. No special tools are required. For care, monitor the barrier after watering; if large gaps appear, add a small amount of new granules to maintain the seal. Store the remaining product in a cool, dry place inside the original packaging to keep the material effective for future applications.
