In the absence of sufficient dead plant material and fungal mycelium, the hungry larvae start attacking the living plant roots and thus damage our beloved plants.
Fungus Gnats – What Works And What Doesn’t How To Get Rid Of Fungus Gnats – What Works And What Doesn’t
Marie Iannotti is a life-long gardener and a veteran Master Gardener with nearly three decades of experience. Besides looking for adults, check plant pots for excessively moist conditions and organic debris where larvae feed. Fungus gnats often remain near potted plants and run across (or rest on) growing media, foliage, compost, and wet mulch piles.If this is not sufficient to reduce the damage to acceptable levels then you may choose to use pesticides. Most of the fungus gnats are female and can lay up to 300 eggs in the crevices of the soil, and the fungus gnat eggs will hatch into larvae within six days. The adult gnats don't do much damage to plants; instead, the larvae will munch on your plant's tiny feeder roots, limiting the plant's ability to take up nutrients and stunting its growth. Also, it can be easily inserted into the soil without using ropes and hooks, making it very easy to use.
How to get rid of fungus gnats - Which?
Before adding the nematodes to the soil, make sure you soak the area because, like the fungus gnat, they prefer dark, moist environments. Bees, ladybirds and other beneficial insects rarely stray into our house or greenhouses, so the risk of accidentally catching them is relatively low.You can make your own fungus gnat spray to eliminate these pests from your household plants and garden. Growing up surrounded by my mom’s lush orchids and African violets, I discovered the magic of bringing nature indoors. While you can also use yellow sticky traps outdoors, in orchards for example, there is a risk that the traps will catch beneficial insects alongside the destructive pests. If you are using double-sided sticky traps, there are a couple of ways you can situate them: You can peel the protective cover off just one side of the trap and lay the trap horizontally on the surface of your plants’ soil, with the sticky side up. Finding the best gnat trap can be hard because they all look almost the same, especially the sticky board ones, but there is a quality difference between all of them.

It is therefore impossible to entirely rule out the possibility of an infestation, even with high-quality soils such as our Plantura potting soils. Of course, they are not only useful in greenhouses and outdoors, but can also be used indoors to help with pests that like to infest houseplants. Lastly, fungus gnat larvae mostly hang out in the top 1-2 inches of your potting mix and they like moist conditions so if your potting mix never dries out, you are helping to proliferate the problem! Fungus gnats are often more of a problem in the fall when houseplants that have been outdoors for the summer, and have become infested, are brought back indoors.Generally speaking, one yellow sticky trap per plant stand or one per square metre is sufficient to monitor a pest infestation. Lastly, cover the soil with a layer of coarse sand of fine gravel which will not only help to keep the soil dry but make it less palatable for the gnats to lay eggs.

The approach has to be two pronged for it to work, you need to attack both the adult flies and the larvae to be able to break the lifecycle. Luckily, there are many ways that you can deal with the problem and effectively eliminate them from your life. This is not to say that you should avoid organic mixes, because I think you can successfully use mixes like this, but is also worth noting.
