Gnat Infestation

Easy Solutions for Dealing with a Gnat Infestation

If you have ever dealt with a gnat infestation then you know how annoying these tiny pests are.  While extremely small, gnats create a huge problem.  Whether being bothersome outdoors or indoors, once they start multiplying it seems you can never get rid of them.  However, there are proven methods to eliminate an infestation, which we have addressed in this article.  That way, if you ever have this problem again, you will know the easiest and quickest resolution.

There are many different types of gnats, one of the more common culprits being the fungus gnat.  The first step in eliminating a gnat infestation is to understand why you have them in the first place, as well as where they like to hide.  If the problem is in the house, it will always be associated with potted plants or atriums.  What happens is that when plants are overwatered, these gnats not only breed but also thrive.  When larvae feed on fungi found on plants, the infestation would be the result.  In this case, check the soil of all indoor potted plants/atriums and if too wet, it should be changed.

Another way a gnat infestation occurs indoors has to do with these insects getting in through a small opening somewhere, usually a window.  Remember, these insects measure between 1/16 and 1/4 of an inch so they can squeeze through the smallest hole.  In this case, below the entry point you would likely find mulch nearby.  If this were the case, you would need to inspect the area outside.  If gnats were found, the problem would need to be addressed on the outside of the house, as well as the inside.

Another possible cause has to do with a water leak.  For instance, if you had water standing in the basement, a kitchen faucet that constantly drips, or even a pet’s water bowl that is always leaving a puddle on the floor, you could very well end up with a gnat infestation.  Obviously, eliminating the water problem would prevent the infestation but first, you would need to take steps to bring the current problem under control.

One of the easiest, safest, and most affordable means of eliminating a gnat infestation is by spraying vinegar onto the area where they are coming from. Some people use 100% apple cider vinegar, some Windex glass cleaner with vinegar, and some a blend of 50% vinegar and 50% water.  This works great for the outside but obviously, this solution would not work well indoors.

For a gnat infestation around fruit, you can also fix the problem easily and without spending more than $3.  Discard the fruit attracting the gnats and then place half a cut red delicious apple inside a plastic zipped bag.  With a sharp knife, poke three holes, each no more than the size of the tip of a dull pencil.  Remember, these insects are incredibly small so you do not need a very large opening.  Then, place the bag with apple inside near where most gnats are found.  Within hours, you would notice the bag with live gnats feasting on the apple.  However, these insects can get inside the bag but not out so they die.

Another similar solution for getting rid of a gnat infestation is to place one-quarter cup of apple cider vinegar, one tablespoon sugar, and about three drops of dishwashing soap in a plastic bag.  Again, poke about three very tiny holes in the bag and place near the problem area.  With this, you do not even need to mix the ingredients.  For the apple in the bag and this gnat infestation solution you may need to replace the bag every four days until all the gnats are gone.  If the problem were minor, they would all be captured in a day or two but if the infestation is serious, it could take a full week.
