10 Fastest Ways to Get Rid Of Gnats in Your House

10 Fastest Ways to Get Rid Of Gnats in Your House

Gants, these tiny insects, which resemble mosquitoes, are the most undesirable and unwelcome visitors to our home. They not only look like mosquitoes but even bite and suck blood from human bodies just the way mosquitoes do. They leave a red spot on your skin and can be very itchy. 

Female gnats can lay up to 300 eggs at a time so it is very much important to get rid of them as soon as you notice. As they can multiply in numbers within a blink of an eye. And can spread the infection way too fast than you can imagine. 

Are Gnats Harmful?

Gnats are little insects with long, slender bodies and very narrow wings that are black or dark brown. And they are considered to be the major cause or trigger for diseases like Myiasis, and microfilaria.

They even carry Leishmania parasites and when they bite it is likely to transmit to another person which eventually leads to Leishmaniasis.

Gnats come in a variety of shapes and sizes, but the most prevalent forms in our homes are fungus gnats, fruit gnats, and phorid or drain gnats.

Fungus gnats: These types of gnats breed on soil and accumulated water. Your indoor or outdoor flower pots can be their favorite spot especially if there is water accumulated. Even if there are any dead leaves it attracts them.

Why Are There So Many Gnats in My House?

Seeing a few Gnats isn’t a big deal as they could be visiting for food. However, if you see swarms of them everywhere, then you’ve got a problem. You need to find the source and get rid of them completely.

Here are a few reasons why your house has so many gnats:

Over Watering Your Indoor or Outdoor Plants

You must be very careful about watering your indoor and outdoor plants and make sure you don’t overwater them. As moist potting soil, damp soil where there is too much moisture is an ideal breeding habitat for fungus gnats’ eggs and larvae. 

Uncleaned Rotten Fruits, Plants, or Any Other Decaying Material

Rotten, overripe, and other sweet fruits attract fruit gnats. So, if you have any rotten fruits in your home, get rid of them right away and cover your overripe fruits.

In the case of Fungi gnats, they are attracted to decaying plants and flowers. Fungus, mildew, moss, and compost are among their favorite foods. They prefer to dwell in potting soil, where they can feed on root rot or decomposing leaves.

Delayed Emptying of Trash Cans 

Make sure you store rubbish in bins with tight lids that cover the whole cans. There is usually a lot of moisture in kitchen garbage cans and decomposing organic waste leftovers of meals, bones, veggies, etc. Leaving these garbage cans open and delay to throw can attract house gnats.

Too Much Moisture in Kitchen and Bathrooms

Gnats prefer to congregate in the kitchen and bathroom because they are a constant source of moisture. The kitchen sink contains unfinished food particles and when the dirty dishes are left for a long time they are attracted to these smells. 

Sometimes our bathroom sink or showers get blocked with hair and other dust particles which results in slow drainage. When there is standing water in the sink it is very enticing for gnats.

Leakage in Drains or Gutters

Another popular site for gnats is a leaking faucet, leaky pipes, or sweating pipes under the kitchen sink. It’s the dark, wet habitat that’s ideal for egg-laying. If there is leakage in roof gutters or any such place this can be ideal for gnats to start breeding and spreading in numbers.

Stagnant Water

If there is any standing water in your yard, or flower pots indoors or outdoor you need to get rid of them immediately. Female gnats lay eggs there as it is perfect for them. Try to keep your yard, washroom, and kitchen dry.  

Fragrance in Skincare products 

If none of the above-mentioned reasons apply to you, then fruit-scented hygiene and cosmetic products sometimes can be the reasons too.

Fruit gnats are drawn to specific floral and fruit scents. If you’ve been using any kind of fragrance or beauty product, they may have been drawn to it as well.
