How to Get Rid of Gnats – Feature Article

Gnats can quickly become a nuisance, posing a challenge to households, businesses, and agricultural environments alike. Knowing how to get rid of gnats is important because these tiny flying insects are not only irritating, but can also contaminate food, spread diseases, and damage plants.

Recently, Joe Malinowski, vice president of pest management at Pest Authority and Mosquito Authority in Kernersville, North Carolina, spoke with about gnat infestations and how to prevent them in the future.

Gnat infestations can signify underlying issues such as poor sanitation, excess moisture, or organic debris buildup. Addressing gnat infestations is essential not only for maintaining hygiene and comfort, but also for protecting health and preserving property. Ignoring the problem can lead to escalating populations, making eradication efforts more difficult over time.

Taking prompt and effective action against gnats is crucial for restoring peace and cleanliness to living spaces and ensuring the well-being of occupants.




What Are Gnats?

Gnats encompass a diverse group of small, flying insects belonging to several families within the order Diptera. While the term “gnat” is often used broadly to refer to any small flying insect, it more specifically includes species such as fungus gnats, fruit flies, and biting midges. 

“There are some 714 species of gnats to be precise, and they are generally found in the interior of a home or commercial property. When in doubt,” said Mr. Malinowski, “it’s best to contact pest control providers quickly — in optimal conditions, gnat eggs hatch in only a few days and can advance to adults in six to eight days.”

Each type of gnat varies in appearance, behavior, and habitat preferences. Gnats undergo complete metamorphosis, consisting of egg, larval, pupal, and adult stages. The lifecycle from egg to adult can range from a few days to several weeks, depending on environmental conditions and species. 

Identifying gnat infestations typically involves observing their small size, erratic flying patterns, and congregation around food sources or moist areas. Understanding the lifecycle and behavior of gnats is crucial for implementing effective control and prevention strategies tailored to specific species and environments.

What Causes Gnats to Appear?

Gnats are commonly attracted to environments with moisture and organic matter, conditions that are ideal for breeding with various factors attributing to their presence. 

One primary cause is poor sanitation practices, such as leaving food crumbs or spills unattended, as well as storing fruits and vegetables improperly. Overripe fruits, decaying plant matter, and standing water act as breeding grounds for gnats, allowing them to multiply rapidly. 

“It’s also worth noting that gnats have a common occurrence on fungi which provides a major food source for their larvae,” said Mr. Malinowski.

Additionally, excessive moisture from leaky pipes, damp soil, or overwatered houseplants creates an inviting habitat for gnats to thrive. Outdoor environments, such as compost piles and stagnant water bodies, also contribute to gnat populations. Understanding these underlying causes is crucial for effective gnat control and prevention strategies.

How to Get Rid of Gnats

Getting rid of gnats requires a multifaceted approach that addresses both the immediate infestation and the underlying factors attracting them. Regular monitoring and maintenance routines can help prevent future infestations, ultimately leading to a gnat-free environment.


Implement thorough sanitation practices, including cleaning up spills, properly storing food, and eliminating sources of organic debris. Gnats sometimes lay eggs in the sink drain or garbage disposal, so pouring boiling water down the drain can kill the eggs before they hatch. 

Try DIY methods

Natural remedies such as homemade traps using vinegar and dish soap, essential oils, or biological control methods can help reduce gnat populations. 

Consider pesticides

Consider using pesticides or commercial repellents for more severe infestations while following safety precautions when applying.

Look for moisture sources

Environmental management is crucial, both indoors and outdoors. This includes ensuring proper ventilation and humidity control indoors and eliminating standing water inside and out. Be careful not to overwater plants, and keep an eye out for potential moisture problems like leaky pipes, windows, roofs, or other cracks, clogged drains, and clogged gutters or downspouts.

How to Prevent Gnats

Prevention measures play a pivotal role in keeping gnats at bay and maintaining a gnat-free environment. Incorporating these prevention measures into your daily routine can significantly reduce the risk of gnat infestations and help maintain a hygienic environment.   

Keep things clean

Implementing cleanliness and sanitation tips is essential, including regularly cleaning up spills, wiping down surfaces, and disposing of organic waste properly. Clear out leftover food, throw out garbage, and keep food in sealed containers to remove smells. 

Eliminate breeding grounds

Properly storing food in airtight containers, sealing trash bags, and emptying garbage bins frequently can reduce gnat attraction. Ensure your home or business has adequate ventilation and humidity control to deter gnats from staying.

Reduce moisture where possible

Remove standing water, fix leaks, and let your plant soil dry out to prevent gnats from being drawn to your property in the first place.

Getting Professional Help

Seeking professional pest control services becomes necessary when gnat infestations persist despite implementing various prevention and eradication methods. Signs indicating the need for professional intervention include large or recurring infestations, difficulty in identifying the source of the problem, or when DIY methods prove ineffective. 


When working with a multi-faceted mosquito control company like Mosquito Authority, clear communication with your pest control professional is key. Be sure to provide accurate information about the extent of the infestation and follow their instructions carefully regarding preparation and follow-up procedures. Additionally, inquire about the safety of the treatments used and any potential health risks, especially if children or pets are present. Collaborating with experienced pest control professionals ensures thorough and effective gnat eradication while minimizing risks to occupants and the environment.

Long-Term Prevention

Long-term prevention strategies are vital for keeping gnats away and maintaining a pest-free environment in the future. Establishing regular maintenance routines, such as consistent cleaning practices and proper waste management, helps eliminate potential breeding grounds and food sources for gnats.


Monitoring for early signs of infestation, such as noticing increased gnat activity or spotting larvae, allows prompt intervention before the problem escalates. By incorporating these long-term prevention measures into everyday habits, you can effectively mitigate the risk of future gnat problems and enjoy a comfortable environment.
