As well as ensuring your indoor plants are watered correctly, you can apply a pesticide. ‘Spray the compost with half-strength BugClear Ultra to kill larvae and adults,’ recommends the Amateur Gardening experts.

‘Do this outdoors, away from food and furniture, leaving the plant for an hour or so before returning it to a windowsill or some other place indoors.’

Pesticides can deter these insects

How To Prevent Gnats

Most of the time these pests are alive they are larvae in the soil so taking care of potting media, organic matter, or soil around the home is a great first step. Ensuring standing water sources are eliminated and that overwatering is not taking place can reduce the access of these gnats to suitable breeding areas. Cleaning up garden soil and removing dead plants and other organic debris can help keep populations from exploding as well. Spraying with insecticides and making the garden space hospitable for friendly insects such as spiders can also help keep the number of fungus gnats under control.


When outdoor gnat infestations get out of hand, they can make it difficult to enjoy your yard or garden space. No one wanted to deal with flying and biting gnats when they are outside trying to relax and have a good time. Controlling gnats naturally can help maintain populations, but sometimes more extreme measures need to be taken for indoor and outdoor gnats that have gotten out of hand. Please see the following FAQ for a few final tips and reminders about dealing with indoor and outdoor gnat infestations.

Can Bottom Watering Prevent Gnats

Bottom watering is the process of putting the plants into a bowl of water. This allows the roots to absorb the water. There are a few benefits to this approach, these include:

  • Helping the plants develop strong roots
  • Keeping the soil moist

But to understand how it affects gnats, we need to first know what makes a plant attractive to these pests. Some elements that they will look for include:

  • Organic matter. This is why gnats can pose a problem for plants. They have been known to feast on the organic matter in the soil. Sometimes, they have been known to eat seedlings. In more established plants, they might eat the root systems. This is why plants that have a gnat infestation will wilt.
  • Moisture. This is something that gardeners will be able to control. Gnats will be attracted to moist soil, laying their eggs inside it.
  • Light. Sometimes, bright lights around your plants can be enough to attract gnats. They like to flock to these sources at night. The condition of your garden will determine whether they stick around.

Since moisture is one of the most important elements attracting gnats to your soil, the way you water the plants is important. This is why bottom can be a good choice. It is an easy way to prevent overwatering while making sure that the plants are getting enough water.

I asked fellow gardeners if they thought bottom watering would prevent gnats in potted plants. It was surprising to see that many of them did not thing so as seen in the poll below.

What Size Fogger To Get ^

For small yards 5,000 sq/ft or less, go with the MINI FOGGER. This unit has a 32 oz holding tank and is strong enough to shoot the mist 15-20 feet.

For 10,000 sq/ft or more, get one of our electric models like our very own BUGSPRAY FOGGER, FM6309 or the FM6208. These machines are able to pump a lot of chemical over a large area in a short amount of time.

Our Bugspray Fogger is the best deal of the lot. Its super powerful, able to pump material at a rate of 2-12 oz per gallon and its fully adjustable so you can control it as needed. This unit makes a great mist for yard pests including both flying and crawling insects. When pumping BITHOR, you can use it for any pest control need, inside the home as well, and do the best job ever since all surfaces will be uniformly treated. Like the other electrics, just fill the tank with water, add the product you want to apply, plug it in and fog away. We have a good video showing how it works if you have further questions but for 1 acre or less, this fogger is well suited.

The FM6309 has fixed rate of chemical flow which is generally okay. But the FM6208 has a dial setting allowing you to turn it to low, medium or high. This is handy for when you need to make delicate applications but its also good for cleaning out the unit prior to storage. Simply turn the chemical control switch to off and let the fogger use up whats in its system and you can then store it for a few days without worrying about the insides getting clogged.
