- It’s unsafe to have gnats around because of the diseases they spread through contamination.
- You can get rid of gnats by reducing moisture in your home, placing traps, and bringing in expert gnat control.
Gnats are most likely in your house because they have found a source of moisture to live in.
If you’re a houseplant owner, you’ve likely dealt with the annoyance that is a fungus gnat infestation. Gnats can appear seemingly out of nowhere in your home. Fungus gnats in particular are known for infesting plants. They typically enter homes here in Louisiana when fungus sprouts due to excess moisture.

Why Do I Have Gnats?
Like other pests, gnats are attracted to excess moisture. When you overwater your houseplants, fungus gnats will lay their eggs on the moist potting soil. The larvae will develop within the soil and quickly hatch. Once they’ve established themselves, fungus gnats can quickly attack other nearby plants.
The humid climate and frequent heavy rains in Louisiana allow gnats to be so persistent. So if you are noticing gnats outdoors, it may be due to an overwatered lawn, a flat roof that lacks proper drainage, or dirty garbage cans that have grown fungus.
Once you’ve identified where the fungus gnats are coming from, you can work to eliminate the conditions causing the infestation.
Health Concerns
These pests may be a nuisance, but they also can spread diseases such as Salmonella and E. coli. Gnats can contaminate food, and certain species may trigger allergic reactions in sensitive individuals. Additionally, biting gnats can leave itchy, irritating welts that may become infected if scratched.
To prevent and get rid of gnats in your home, it’s important to avoid the things that would attract them in the first place.
How to Get Rid of Fungus Gnats in Louisiana
In order to get rid of gnats, it’s important to focus on getting rid of the larvae that may be in your soil. The key to keeping them away for good is preventing the environment that attracts them in the first place. Here’s what to do:
- Avoid watering your plants to the point where the soil stays wet for days at a time. You can rake the soil to help it dry quicker.
- Never let water sit in the drainage tray beneath plant pots. Always make sure your houseplants have the best drainage possible by incorporating gravel, sand, and more into your potting soil.
- Quarantine the plant pot that has the infestation. Consider taking it outdoors and removing the top layer of wet soil entirely.
- Place sticky traps in the plant itself to get rid of adult fungus gnats.
To get rid of outdoor gnats, make sure not to overwater your lawn, keep your garbage sealed properly, and make sure you have proper drainage on your roof and elsewhere. But overall, the best thing you can do is call an exterminator near you in Louisiana.

FAQs
What kind of gnats bite in Louisiana?
Here in Louisiana, the most common biting gnats are black flies and biting midges (often called “no-see-ums”).
Unlike fungus gnats, which are harmless to humans, biting gnats can leave painful, itchy bites that may swell and cause discomfort for days.
What smell do gnats hate the most?
Gnats are repelled by several strong scents, which can be useful for keeping them at bay. Some of the most effective include: peppermint oil, eucalyptus, lavender, citronella, and lemongrass.
Consider placing essential oil diffusers near problem areas or adding a few drops to a spray bottle with water to create a natural repellent.
Do coffee grounds or dryer sheets repel gnats?
Coffee grounds can help dry out moist soil, making it less hospitable for fungus gnat larvae. However, they won’t repel adult gnats on their own. Dryer sheets contain fragrances that may also deter gnats.
How long do gnats typically live?
The lifespan of a gnat depends on the species, but most adult gnats only live for about 7 to 10 days.
