Plant pots can provide the perfect breeding ground for gnats, so you’ll need to remove them if they infest your plants.

As you might know that the fungus gnats love the moist soil alot because it is the place where the fungus can easily and properly develop.

Overwatering and not letting the soil completely dry is the only reason you are facing the fungus gnats problem.

Always keep in mind the moister the soil is the chances of fungus will be more. 

Most plants should be allowed to dry completely before rewatering after a hydration period of 20% to 50%. 

There are two types of gnats that feed on decaying matter in soil and fungi. A healthy soil medium will also have both types of gnats in it

To prevent the overwatering or under-drying soil problem you can invest in some good quality sub-irrigated planters.

Using these planters the upper layer of soil will quickly get dry as result there will be no fungus problem. 

Deal With Gnats Eggs:

In order to eliminate fungus gnats from a plant, both the larvae in the soil and the adult flies must be eradicated. Interrupting their life cycles is the only way to eliminate them.

Taking care of the adults will not prevent the eggs from hatching or the larvae from developing into adults.

It is not possible to stop the adults from laying eggs by dealing with the eggs and nymphs in the soil.

In order to prevent fungus gnats from laying eggs within your soil, add 2 inches of horticultural sand or diatomaceous earth over your plants’ potting mix.

Put Out Sticky Traps:

Have you ever seen the sticky gnats traps? If yes then you might not or might have thought about the yellow color.

The sticky traps are mostly yellow colored it is because the gnats are very attracted to the yellow color. 

There may have already been gnats laying their eggs when they fell into the trap, indicating that more gnats will hatch soon.

These yellow sticky traps are one of the most effective and easy ways to get rid of gnats.

When it comes to planting care, it is always better to avoid problems than fix them, so observe your watering processes carefully and make sure you dont overwater the plant. 

Deter Baby Gnats Already In The Potting Mix:

If you want to kill flying insects like fungus gnats, you can use Mosquito Bits, which is a natural larvicide for waterings that will kill larvae of insect-like insects.

The best way to release the bacteria from the bits is to soak them in water for 20 minutes, then add them to your plants’ water.

Once the plants are watered, you can spray them with larvicide, which will kill the larvae when they feed.

Insecticides are one of the most effective methods to control gnat infestations as they target the pest at the point of its lifecycle when it feeds the longest.

Incorporate Organic Insecticide Into Watering:

It’s always better to take preventive measures at the very start of the growth of these gnats.

If you take preventive measures early then it will be easier for you to overcome the problematic situation.

If this tip sounds good to you then investing in some best organic insecticides will be very helpful for you.

Or if you want a DIY organic insecticide then all you need is some good quality neem oil it is going to work wonderfully.

Adding the bits to your plants’ water will release the bacteria after 20 minutes of soaking.

When the larvae start feeding on the plants, the larvicide will kill them. You can then thoroughly water them.

This is one of the most effective ways as it targets and destroys the gnats at a very early age.
