Causes Of Fungus Gnat Infestation
Knowing how to kill fungus gnats is easy, but it’s better off to prevent them altogether. Part of doing that is understanding what causes an infestation in the first place.
Fungus gnat eggs are generally planted in overly moist soil, though outdoors they’re known to even use moist, rotting wood. If it’s moist and has fungus growing, especially in topsoil, they like it.
Early intervention is the key to preventing an outbreak. If you see adults flying around in any significant numbers you need to act in the ways mentioned above, and quickly since their life cycle is so fast.
You need to get rid of the adults and stop eggs from hatching and larvae from developing all at once, otherwise multiple generations can grow while you’re just dealing with the adults over and over.
The cause of an infestation indoors and outdoors is simply a lack on your part to attack at least two stages of the life cycle to put an end to the replication.

How Do You Get Rid Of Grass Rust
Good news here! Grass rust is probably the easiest lawn disease to get rid of.
An application of a high-nitrogen, quick-release fertilizer, such as Scotts Turf Builder WinterGuard Fall Lawn Food, when rust appears will make it disappear quickly. Nitrogen triggers leaf growth. This surge of growth when the lawn is naturally trying to slow down will grow the grass out of trouble. If your lawn is dry, watering the grass will also stimulate growth. Applying a fungicide is seldom necessary and not recommended.
How To Prevent Fungus Gnats
Of course, once you get rid of your fungus gnat problem, you’ll want to do what you can to prevent it the next time. Thankfully these are very passive methods that take nearly zero effort the first time and then you don’t have to do anything else.
Inspect Plants Before Purchase – If you see any fungus gnats fly up when handling the potted plant, reject it and those around it. You can turn up an inch or two of soil and see if you can find any larvae.
Let Your Soil Dry Out – The first thing you can do is make sure you allow more time to pass between waterings of your plants.
Fungus gnats like to lay their eggs in moist soil, so if the top is too dry for their taste, they’ll move on to another location . Just pinch the top inch of your soil occasionally to check dryness.
Add a Layer of Sand – Another way to keep your soil dry is to place about a 1/2 of an inch of coarse sand across the top of your soil. It’s not the prettiest solution but it drains quickly so adult gnats won’t be tempted to lay eggs.
It also helps stop growing larvae from every being able to emerge out of the soil and through the sand. The annoyance with this is you’ll need to start watering from the bottom of your container so you don’t wash the sand away.
Cover the Drainage Holes – If you’re taking care of the top portions of the soil as mentioned above, fungus gnats will still seek out the moist drainage holes, so you need to cover them too.
