What are gnats?
Gnats are tiny flies that are often drawn to decaying organic material, standing water, moisture, and dampness. There are many different species of gnats, some of which bite and others that do not. Some of the most common gnats include:
- Fruit flies – Small flies that are attracted to ripe or rotting fruit.
- Drain flies – Breed in drains, sewers, and damp areas.
- Moth flies – Harmless flies that look like small moths.
- Phorid flies – Tiny humpbacked flies that breed in moist organic matter.
- Fungus gnats – Attracted to damp soil and decaying plants.
- Black flies – Biting flies that breed near moving water.
- Sand flies – Tiny biting flies found near water and sandy areas.
While gnats are more annoying than dangerous, their bites can cause irritation, welts, and itching. Large swarms near food preparation areas can also pose a contamination risk. Getting rid of standing water, fixing leaks, cleaning drains, and removing decaying matter can help control gnat populations by eliminating breeding sites.
Why use peppermint oil?
Peppermint oil is derived from the peppermint plant, a hybrid of water mint and spearmint. The active ingredient in peppermint oil is menthol, which gives it a strong minty aroma and flavor. Peppermint oil has a number of benefits when it comes to repelling gnats:
- Strong smell deters gnats – Gnats dislike the potent smell of peppermint.
- Non-toxic to humans – Peppermint oil is safe to use around food, pets, and children when diluted properly.
- Natural ingredient – Derived from the peppermint plant so it’s environmentally friendly.
- Also repels other insects – Effective against flies, mosquitoes, spiders, roaches, and more.
- Available and affordable – Can be purchased at most grocery stores and online retailers.
Research shows that peppermint oil can repel a variety of flying and crawling pests. The strong scent confuses their senses and makes it hard for them to breed and feed. Using natural options like peppermint oil allows you to keep gnats at bay without worrying about toxicity or harsh chemicals.
How to use peppermint oil for gnats
There are several different ways you can use peppermint oil to help get rid of gnats inside and outside your home:
Potted plants
Add a few drops of peppermint oil to the soil of potted plants. This deters fungus gnats which lay eggs in damp potting soil. Just be careful not to overdo it with the peppermint oil as too much can harm your plants.
Homemade sprays and solutions
Making homemade peppermint sprays and solutions is an easy way to use the oil throughout your home:
- Peppermint spray – Add 15-20 drops of peppermint oil to a spray bottle filled with water. Mist around windows, doorways, and other flyways.
- Peppermint furniture polish – Mix peppermint oil into your favorite wood polish and apply to furniture.
- Peppermint floor cleaner – Add 5-10 drops of oil per gallon of floor cleaning solution.
- Outdoor peppermint spray – Make a strong solution with 20 drops of oil per cup of water and spray patios, decks, and outdoor furniture.
Essential oil diffusers
Use a diffuser to disperse the smell of peppermint oil throughout the rooms in your home. Follow your diffuser directions to add the appropriate number of drops. The lingering scent will deter gnats and freshen up your indoor spaces.
Sachets or pouches
Small breathable sachets filled with cotton balls and peppermint oil can be placed discreetly around your home. Put them in cupboards, drawers, closets, etc. As the oil evaporates over time, the scent will repel gnats that getting inside.
Dryer sheets
Soaking dryer sheets in diluted peppermint oil and then tossing them in areas like basements, garages, and sheds fills the air with gnat-repelling fragrance.
Personal repellent sprays
Make a peppermint oil personal repellent spray to keep gnats at bay when outdoors. Add 1 tablespoon of carrier oil like coconut or jojoba oil to 10-15 drops of peppermint oil. Transfer to a small spray bottle to spritz on skin and clothing.
Tips for using peppermint oil effectively
Follow these tips to make sure you use peppermint oil safely and effectively for gnat control:
- Always dilute peppermint oil before use – It’s very potent undiluted.
- Test on a small area first when spraying – Check for any damage or discoloration.
- Reapply every few days – The smell doesn’t last forever so refresh as needed.
- Use along with other control methods – Peppermint oil works best alongside proper sanitation and gnat-proofing.
- Keep out of reach of children and pets.
- Avoid getting peppermint oil on furnishings – The smell can linger.
- Open windows if the scent is too strong indoors.
Does peppermint oil work for gnats?
The effectiveness of peppermint oil against gnats depends on several factors:
- Method of use – How you apply the oil makes a difference. Sprays work better than oils in diffusers for repelling flying insects.
- Infestation level – Peppermint oil works best at warding off gnats versus eliminating existing severe infestations.
- Proper dilution – Using peppermint oil undiluted can damage surfaces and may be less effective.
- Coverage area – Needs to be reapplied frequently and may not reach all gnat hideouts.
- Gnat type – Some gnat species may be more averse to mint than others.
- Other control methods – Works best when enhancing sanitation, drain treatment, etc.
Overall, peppermint oil is most useful as a supplemental gnat deterrent. Relying solely on oil likely won’t solve a serious infestation. But as part of your integrated pest management, it can provide an added layer of prevention and protection.
Safety precautions
Peppermint oil is generally recognized as safe by the FDA. However, there are some important safety notes regarding its use:
- Avoid eye contact – Peppermint oil can irritate eyes.
- Keep away from pets – Toxic if pets ingest the oil.
- Use proper ventilation – The scent can cause headaches and nausea if too strong.
- Test skin sensitivity – Do a patch test before widespread use.
- Don’t use on young children – May cause skin irritation.
Make sure to purchase 100% pure peppermint oil from a reputable source. Dilute the oil properly before use and follow all label instructions. With the right precautions, peppermint oil can be an effective chemical-free way to discourage gnats from invading your home and outdoor living spaces.

Frequently Asked Questions
How long does peppermint oil last for gnats?

Are homemade peppermint sprays effective?
Yes, homemade peppermint sprays can be extremely effective! Mixing the oil with water amplifies its gnat-repelling properties. Spraying the solution directly on known gnat routes and hangouts drives the pests away.
How do you use peppermint oil in plants?
