Fungus gnats thrive in moist, saturated conditions, so cultural practices should be utilized to limit freestanding water and over-saturated growing media. You will need to treat all of your plants that are planted in potting soil, not just the ones showing signs of infestation. Got some sticky yellow stickers, which has made the problem a lot more obvious, but done little to reduce it. Continuous and overlapping generations of fungus gnats in the greenhouse have made most control strategies difficult.

Within the now dead larvea there will start to grow a new generation of useful nematodes that will once again start to seek out larvae to infect. See our Eco Sticky Traps, Yellow Sticky Traps, Extra Large Yellow Sticky Traps , or our Mini Sticky Traps(for smaller pots). Fungus gnat larvae tunnel into thick, succulent stems and roots, causing the plant to wilt and, in severe infestations, die. It is best to use some of our yellow sticky traps in combination with your nematode treatment to prevent the build up of a large infestation.If fungus gnats are already present, it will take 2 to 3 weeks for the adult flies to die off and for all larvae to be killed by the nematodes. Most species play a very important role in nutrient cycling and release of nutrients for plant growth. Biological control agents including Bacillus thuringiensis (Bt), the predatory mite, Hypoaspis miles and entomopathogenic nematodes have been used as alternatives to chemical pesticides.

Can be used on all indoor house plants, tropical plants, and any time you add more potting soil to your plants Easy to apply with a watering can or hose-end sprayer for outdoor uses Fungus gnat control nematodes are microscopic worms that seek out larval stages of various fly and other Diptera insects that develop in the soil. For the control of fungus gnat larvae, we offer various products that work on the basis of SF nematodes.In the 1960s, additional options were developed with the establishment of integrated pest management (IPM).

Fungus gnats / sciarid flies are usually a problem with young seedlings and cuttings during the first six weeks of cultivation. Scanmask is available in many quantities, so it is easy to purchase the amount you need depending on how many indoor plants you need to treat. Parasitic nematodes seek out suitable hosts by swimming in the thin film of water on soil particles, locating hosts by detecting carbon dioxide and other waste products. Our newsletters will provide you with access to exclusive discount codes, new products, and all the latest pest control advice from Dragonfli experts. We offer a 10m 2 kit containing both the nematodes and yellow sticky traps, or a 20m 2 pack size depending on the area you need to treat.Because fungus gnats are weak fliers, physical barriers like mesh screens can be used in vents and doorways to minimize pest movement. Common egg-laying sites include moist organic debris/potting soil, decaying wood (mulch), and ground cover plants. Using the NemaKnights Fungus Gnat control can act as a preventative measure against fungus gnat populations.

If using a watering can stir and pour a portion of the liquid into the watering can and add more water, then water pots or affected soil.The beneficial nematodes will parasitize existing fungus gnat larvae, slow their feeding and kill them. When using as a curative treatment for an existing problem, best results are obtained by two separate applications 10-14 days apart.
