Possible Reasons For Gnats Presence in Refrigerator

Gnats in Refrigerator

There are two possible reasons for the presence of gnats inside the refrigerator. The first one is simple, the presence of decayed or rotten food inside the refrigerator. Gnats are attracted to decayed organic matter, so always try to remove food materials that can no longer be eaten.

Second, comes the availability of passage. If the door is kept open, gnats are most likely to grab this opportunity and will enter into the refrigerator.

Also, if there is a problem with the gasket, they will find a way into the fridge. The gasket is an elastic strip that is attached to the outer edge of a refrigerator.

Having a problem with the gasket means the door is not sealed properly. There could be debris along the gasket that is preventing the door from closing properly. This provides a passage for gnats to make their way into the refrigerator.

It is advised to clean the gasket and then do a test to ensure that there is no gap. The test is simple. 

You will need to grab a piece of paper and then put it between the door of the fridge. Try to pull out the paper. If there is tension felt while doing so, then everything is fine.

But if there is no tension felt i.e. you can easily pull out the paper then a repair or replacement is required. This should be done to prevent the entry of gnats into the refrigerator.

How Do Gnats Get Inside the Refrigerator?

The doors are closed all the time, so how is it possible for gnats to get inside the refrigerator? Maybe they are so fast that they get inside while we open it to get some things. Let’s find out.

Gnats mostly enter refrigerators through its doors. They do so when we mistakenly keep the fridge open for a longer time. Gnats grab this opportunity.

Sometimes they may enter even if the doors are not opened for a long time. We don’t even notice this as they are very tiny and fast.

Few homeowners keep large baskets inside their refrigerators, which stops the doors from completely closing. Gnats use this gap to enter into the fridge.

Those gnats that are present inside the fridge, find their way to the freezer through the vent. They can enter there with the help of doors also. But since freezers are not used too much, gnats don’t get enough opportunity to make their way to the freezer through its doors.

Although most of the gnats use doors for their entry inside the fridge or freezer, another entry point is through fruits and vegetables. Gnats could have already been present over the edibles before putting them inside the fridge. 

How Long Can Gnats Survive in the Refrigerator?
