Fungus Gnats In House With No Plants: Why & What To Do!

Fungus Gnats are tiny, black, or dark-brown insects that have thin wings and long, slender bodies that are 1/4 inch in length. What you observe are fully developed adult gnats, even though they appear to be little flies.

Gnats come in two varieties: non-biting and biting, although the ones you commonly see in your home and yard are the non-biting variety.

Given that they cannot bite humans and cannot transmit diseases, fungus gnats are completely safe to be around. They might cause issues for indoor plants.

But if you don’t have any plants, you don’t really have to worry about them. They can, however, annoy you if their population explodes.

It is all because of the scent. The majority of gnats are attracted to certain smells, especially fruit and sweet scents. The majority of us utilize a range of personal hygiene items.

You must first identify their cause in order to understand how to get rid of fungus gnats. They have several entry points into your home, including the outside, eggs laid in produce, and potting soil.

Gnats typically live in polluted soil outside and in containers where fungus can grow because of moisture. But there are also lots of other factors.

If your house has fungus gnats while having no plants, you must investigate the problem and its causes.

Why Do I Have Gnats If I Don’t Have Plants?

Gnats can be found in places that have higher humidity and colder temperatures.

Places other than plant soil, where you will find fungus gnats include basement bathrooms, cooling ducts in air conditioning units, and drain pipes.

They are also caused by water-related problems, such as broken appliances or basement pipes that are leaking.

The majority of gnats’ food comes from eggs laid in unripe fruits. When the fruit starts to deteriorate, the larvae consume it to develop into adult gnats.

Furthermore, open windows or doors can also allow gnats to enter your house. If you have a nearby trash bin with a gnat infestation, it’s typical to have a few of these insects trickle inside.

How Do You Get Rid Of Fungus Gnats When You Don’t Have Plants?

Even though gnats can live for up to four weeks, you must act quickly to eliminate them from your home since they breed quickly.

Before dying in 7–10 days, a female gnat can deposit up to 100–300 eggs at a time, up to 30 times.

You have to look for the source of the gnats in your house first, once the source has been identified, start taking action to eliminate the source and breeding ground of the gnats.

Here are a few ways to get rid of fungus gnats when you don’t have plants:

  • Combine one cup of water, a tablespoon of vinegar, and a little dish soap in a spray bottle. If you see gnats flying past, spray this mixture directly at them.
  • Fungus gnats, which are tiny, can look like glitter clouds in rainy weather and tropical temperatures. To capture them, leave trays of dishwashing liquid out overnight.
  • Hang vanilla and gently entice them back outside because they are drawn to the color yellow, setting traps or glue traps is preferable. Then they won’t disturb you because they will ultimately locate dirt.
  • If you can, remove the old AC window units that were in storage where the gnats can sit.
  • For your outdoor pests, there is also an option of electric fly exploders.

How to prevent gnats from coming back:

  • Food shouldn’t be left out. This includes cleaning your used cups and dishes. Gnats will be drawn to any trace of juice, wine, or sauce.
  • Eliminate any moist places. Fix your dripping faucets and pipes. Get a foam insulator to cover the pipes and prevent dampness.
  • Cover the trash containers. The trash should be taken out as frequently as you can. Gnats and other creepy crawlies both love to live in stinky trash cans.

Where Do Fungus Gnats Come From In My House?

As we mentioned earlier, gnats like moisture so it is obvious that they will come from damp areas.

Food spills, wet potting soil, overwatered grass or plants, trash cans, puddles in the kitchen or outside your home, dripping pipes under the sink, and condensation around windows and vents are all examples of damp areas that serve as gnat breeding grounds.

Also, gnats might enter your home through open windows or doors. It’s usual to have a few of these insects get inside if there is a neighboring garbage can with a gnat infestation.

Once the source has been identified, action should be taken to eliminate the food source and breeding ground of the gnats.

Why Am I Getting So Many Gnats In My House?

Since gnats are drawn to moisture, the summer is when you are most likely to see them. They frequently congregate in moist parts of your house, such as the kitchen drain or potting soil.

Additionally, it implies that elements like food spills, open trash cans, or potted houseplants can all help to fuel an infestation.

They are also attracted to sweet-smelling fruits, which arise when produce is left out in the open.

Additionally, they are drawn to any decaying or dropped fruit in your garden.

They eat things like moss, compost, fungus, and mold. They often reside in the potting soil where they can consume either decaying leaves or root rot.

The typical household gnat is attracted by sweat, body heat, mucus from your nose, tears from your eyes, and carbon dioxide.

If you have a gnat problem, stay away from fruit-scented lotions, perfumes, hairsprays, and detergents as they also enjoy sweet scents.

Gnats also cluster around lamps and light fixtures because they can’t fly properly in the dark, similar to flies.

Gnats can survive for up to four weeks, but since they multiply quickly, you must take quick action to get rid of them from your home.
