Gnats are more commonly found in indoor plants because the soil in pots stays moist for longer periods, creating a perfect breeding ground for them. Overwatering your plants can also contribute to the growth of gnats.

There are different types of gnats, but the most common ones found in houseplants are fungus gnats.
These gnats feed on fungi that grow in moist soil, and they lay their eggs in the soil as well. When the eggs hatch, the larvae feed on the organic matter in the soil, and the cycle continues.
Gnats can be identified by their small size, typically about 1/8 inch long, and their habit of flying around the soil of your plants. They can also be seen hovering around the leaves of your plants.
It’s important to get rid of gnats as soon as possible because they can multiply quickly and cause damage to your plants. In the next section, we will discuss some effective ways to get rid of gnats in your indoor plants.

Gnat Infestation in Indoor Plants
To prevent and treat a gnat infestation in your indoor plants, there are a few things you can do:
- Allow the soil to dry out between watering to reduce the moisture that gnats need to survive.
- Use yellow sticky traps to catch adult gnats and monitor the infestation.
- Repot your plant with fresh, sterile soil to remove any larvae in the soil.
- Apply a gnat spray specifically designed for indoor plants, following the instructions carefully.
When using any gnat spray, it’s important to read the label and follow the instructions carefully. Some sprays may be harmful to your plants or pets if used improperly.

Causes of Gnat Infestation
One of the most common causes of gnat infestation is overwatering your plants. Gnats thrive in moist soil, and overwatering provides the perfect environment for them to breed and lay their eggs.
Make sure to water your plants only when the soil is dry to the touch, and avoid leaving standing water in the saucers.
Another cause of gnat infestation is the presence of organic matter in the soil. Fungus gnat larvae feed on decaying plant matter, so if you have not removed any dead leaves or other plant debris from the soil, it can attract gnats to your plants.

Damp soil is another factor that can attract gnats to your indoor plants. If the soil is too damp, it can create the perfect breeding ground for gnats. Make sure to allow the soil to dry out between watering to prevent gnat infestations.
Common Gnat Traps
Dealing with gnats in indoor plants can be frustrating, but there are many common gnat traps that can help you get rid of them. Here are some popular options to consider:
- Sticky Traps: These are adhesive strips or cards that you can place near your plants to trap gnats and other flying insects. They are easy to use and relatively inexpensive. You can find them in various colors, including yellow, which is particularly attractive to gnats.
- DIY Gnat Trap: You can make your own gnat trap using household items. For example, you can fill a shallow dish with apple cider vinegar and a drop of dish soap. The vinegar attracts the gnats, and the soap breaks the surface tension, causing them to drown. You can also use red wine or beer instead of vinegar.
- Candle Trap: Gnats are attracted to light, so you can use a candle trap to lure them away from your plants. Simply light a candle near your plants and wait for the gnats to fly towards it. You can then swat them or use a vacuum cleaner to suck them up.
- Fruit Trap: Gnats are also attracted to ripe or rotting fruit. You can use this to your advantage by placing a piece of fruit in a jar with a narrow opening. Cover the opening with plastic wrap and poke several holes in it. The gnats will be attracted to the fruit and will fly into the jar, where they will be trapped.
- Sticky Fly Traps: These are similar to sticky traps but are larger and can be hung from the ceiling. They are particularly useful if you have a large infestation of gnats.
- Vinegar Trap: Another option is to use a vinegar trap, which is similar to the DIY gnat trap. Simply fill a jar with apple cider vinegar and a drop of dish soap, and cover the opening with plastic wrap. Poke several holes in the plastic wrap, and the gnats will be attracted to the vinegar and will fly into the jar.
Homemade Gnat Sprays

Spray the mixture on your indoor plants to keep the gnats at bay.
You can also make a gnat trap using apple cider vinegar, dish soap, and sugar. Mix a few tablespoons of apple cider vinegar, a few drops of dish soap, and a little sugar in a small saucer.
