Inside the home, gnats can be attracted to unsealed produce, fresh flowers, houseplants, food spillage and open or overflowing garbage cans. Gnats may also live in sink drains where food residue can collect. Dirty kitchen sink drains can provide food, water, shelter and breeding sites to many fly species.
The quickest solution to getting rid of gnats is to clean your space and remove any trash or unsealed food. Wipe down counters, clean drains, and make sure there is no standing water in your sink.
Probably because you're not killing off enough of the larvae that live in the soil, so they just keep producing new adults.
Where do gnats come from? Gnats come to find a breeding ground and place to lay their eggs. They seek out moist places, decomposing organic matter and damp soil of houseplants, and can be found around your trash or recycling bin.
Too much moisture in bathrooms and kitchens.
Drain gnats multiply when moisture builds up in bathrooms and kitchens, so you may attract drain gnats if you have faulty pipes, vents, and sinks in your home.
The only way to get rid of gnats without killing them is to repel them with scents they don't like: vinegar, vanilla, pine oil, peppermint, lemon, eucalyptus, and lavender. Even dryer sheets could help. Of course, the first line of duty would be to get rid of the infestation's root cause.
Excess moisture in and around your home, such as damp soil, wet houseplants, or leaky pipes, can attract gnats looking for breeding sites.
Fruit traps - Some homeowners use a jar of rotting fruit covered with perforated plastic wrap to lure and then trap gnats. Red Wine Traps Vinegar - Similar to a fruit trap, this option uses the gnats' attraction to these pungent liquids to trap them inside a jar.
In cooler weather it can take 4 to 5 weeks or more to complete the life cycle, so winter treatment can take longer. That's why I always recommend treating for 2 months (8 weeks), but at least 4 weeks minimum if you've caught it early and only have a tiny infestation.
In general, gnats go through the four life stages of egg, larva, pupa and adult, similar to other flies. The fungus gnats lay their eggs in moist organic debris or soil, which hatch into larvae. The larvae feed on organic matter such as leaf mold, mulch, compost, grass clippings, root hairs and fungi.
Geoff: Despite being one of the most common indoor plant pests, fungus gnats are notoriously hardy and difficult to get rid of. They are drawn to moist conditions and, as their name suggests, feed on fungus and other organic matter.
In various cultures and spiritual traditions, gnats are seen as messengers, bearers of lessons that we might overlook due to their size and perceived insignificance. Yet, these tiny beings remind us that even the smallest aspects of life are imbued with purpose and meaning.
Homemade gnat repellent spray: A mixture of dish soap, water, baking soda, and vinegar can be filled into a spray bottle. The mixture should contain a few drops of dish soap, a tablespoon of vinegar, and baking soda per cup of water. A few sprays of this mixture is an effective gnat repellent.
Or, you can switch up your favorite scent with something they don't like. Try Lighting citronella candles using lemon or vanilla sprays. While gnats are a fan of sweet-smelling fruit, they can't seem to stand vanilla, lemon, or even lavender. A little spritz can at least keep them at bay.
Gnats, especially fungus gnats, are attracted to damp soil and that's where they lay their eggs. If you're overwatering your plants, these bugs will find their way there and start laying eggs. They can lay up to 800 eggs in one breeding cycle so this can become a major problem very quickly.
Eradicate your fungus gnat infestation for good with the following method: Put up a bunch of sticky traps, top-dress the soil with sand and do nematode soaks every 10 to 14 days until the problem is resolved. Also, stop overwatering your plants and eliminate any unnecessary sources of moisture. That's it.
If you don't have vinegar at home, bleach will kill drain gnats, but it's a potent environmental pollutant, so you're better off running to the store for vinegar, which is actually more effective for cleaning your drain pipes.
How to Know If You Have Gnats. Unlike roaches, which can be hard to spot because they mostly come out at night and hide during the day, gnats are easy to spot because they swarm at all hours of the day. If you see one and are wondering if there may be more, head to your plants, windows, and lights.
Inside the home, gnats can be attracted to unsealed produce, fresh flowers, houseplants, food spillage and open or overflowing garbage cans. Gnats may also live in sink drains where food residue can collect. Dirty kitchen sink drains can provide food, water, shelter and breeding sites to many fly species.
Fill a glass or a bowl with 1 tablespoon of sugar, 2 tablespoons of apple cider vinegar, a half cup of warm water, and about 5 drops of liquid dish soap and stir well. Gnats will be attracted to the sweet sugar and pungent vinegar, but the sticky dish soap will disable them from escaping.
Additionally, houseplants can harbor gnats, particularly fungus gnats, which lay their eggs in moist soil. The larvae then feed on organic matter in the soil, potentially harming plants and causing an infestation. Overwatering plants only makes this situation worse.
Gnats are seasonal; they are a springtime pest. Once we get consistent summer weather, they will go away. Their life cycle is short - usually mid-May to late June is when we see gnats.
Apply Hydrogen Peroxide
While traps help control the adult population of fungus gnats, you still need to treat the eggs and larvae in the soil. Make a solution by mixing 1 part hydrogen peroxide and 4 parts water, then pour the mixture into the pot, making sure to completely saturate the soil, says Royer.
