How to Kill Gnats in Your Bathroom?

The most common types of gnats that you will find around your home are called fungus gnats. They have dark bodies with clear type wings, looking almost like mosquitoes. But if you ever wondered what they are doing in your bathroom, it’s because they are attracted to the water. That means you will find them at drains, showers, toilet bowls, any moist places. If you have infected house plants in your house, gnats come from the soil of these infected plants. They don’t bite like mosquitoes do, and they don’t spread disease either. In fact they are not dangerous, they’re just a total nuisance.

Adult gnats become attracted to water and light. You will find them gathering around lights, sinks or windows. The bathroom is their favorite room followed by the kitchen. The adult gnat will lay its eggs in the soil of the infected house plant. The larvae of the gnats live in that soil, feeding on any fungal matter. The larvae can actually eat the root of the plants, and the plant can wilt as a result. If the infestation is severe, the damage to the plant can be pretty severe.

Where do gnats come from?

Gnats come from places like moist vegetables and fruits that are kept in bags and start rotting in your cupboards and pantries. The fungus gnats are drawn completely to any organic matter that is busy decaying. That is for them the perfect meal. You need to remove fruit that is getting soft, liquidizing and oozing because you will be sure to see gnats flying around it.

How to get rid of gnats in your bathroom?

It’s a technique that is used to apply diluted chemical pesticides, herbicides, fungicides and even fertilizers to a certain plant or tree. Rather than spraying an entire lot of plants for instance, a soil drench in this instance is applied into the affected pot’ soaking in and dealing with the larvae, without affecting the plant. If your plant is very badly infected, sometimes it might just be better for you to move it outdoors for a while to deal with it there, or else throw it away. If you are serious about getting rid of gnats in your home, you will need then to go further and do an inspection of any new plants before you bring them indoors. Try and avoid using the same potting soil that you were using outdoors. Rather get brand new potting soil.

Gnats can be carnivorous

Gnats also feed on pollen from plants and other plants. Some gnats are even carnivorous. They chew on dead organic matter. Sometimes in the summer you can see male gnats all swarming together towards evening. Gnats still manage to be pests in the home. Even though here are a lot of different species of the gnat, it will depend on their diet and food source what their color will be. This can vary a bit. A real effective way of getting rid of gnats is to buy a gnat trap. They are very convenient and inexpensive. In fact, they are just like fly strips.

Natural home remedies to get rid of gnats

1. Vinegar Trap

But it will be the soap in the liquid which will trap them and kill them.

2. Ammonia or Bleach

If you have gnats near the bathroom sink, a good homemade method is to just pour some bleach or ammonia down the sink. But DON’T mix the two together, because that will create a horrible poisonous gas. Some people prefer ammonia, just pouring a bottle down the sink. Did you know that gnats can live deep inside the pipes, so flushing ammonia down will kill gnats that lurking there.

3. A jar with apple cider vinegar

The most natural simplest war to get rid of gnats is just simply using a mason jar. Fill it with some apple cider vinegar. Poke quite a few quarter-inch little holes in the jar lid and leave overnight. The gnats will be drawn to the smell and enter the jar but they will not be able to get out.

4. Harmless baking soda

All you do is make paste with baking soda. Apart from that you will need only 2 more things, a bowl and some water.  Place some baking soda in a bowl, adding some water to form a paste. Then apply this paste on your bath tub, allowing it to stand for around 5-10 minutes. After the minutes have passed, wash out your bath tub, using a scrubbing brush with hot water. That will definitely get rid of any eggs of the gnats that remain in your bath room. Do this for your shower and toilet too.

Product Recommendations

* Foggers: You will find many fogger-products available on the market. It’s because they are so effective.

* Keep your house clean:  Don’t leave food around where gnats can lay their eggs, especially on dirty dishes that aren’t washed soon enough. Buy a trash bin that has a lid, keeping bacteria from spreading as well as keeping the odors away in consideration of your neighbors and to keep the gnats away, which are attracted to the odors. Gnats are drawn to the strong smells. Strong odors like rotting flesh, rotten foods, rotten wood; these are the scents that will draw gnats to your home. They are like bees as well when it comes to the sugar that is found in the soda cans.

* Replace indoor plants by throwing away seriously affected plants, or buying a soil drench for not such damaged plants. Grow new plants and new potting soil.

* Check windows and doors of your house to ensure there are no cracks and holes where gnats can enter in. In the summer time, if doors and windows need to be open to get in fresh breezes, keep gnats from entering in by installing mesh screens at windows and doors.
