Natural Remedies To Get Rid Of Gnats

Natural remedies can be effective in getting rid of gnats without the use of harmful chemicals. Here are some natural solutions to help eliminate gnats:

1. Apple Cider Vinegar Trap

Fill a small bowl or jar with apple cider vinegar and add a few drops of dish soap. The scent of vinegar attracts gnats, and the soap breaks the surface tension, causing them to sink and drown.

2. Red Wine Trap

Similarly, you can use red wine instead of apple cider vinegar to attract and trap gnats. Place a small amount of red wine in a container with a few drops of dish soap.

3. Fruit Trap

Cut up a piece of ripe fruit and place it in a container. Cover the container with plastic wrap and poke small holes in the wrap. The fruit will lure in gnats but will have difficulty escaping.

4. Vinegar And Dish Soap Spray

Mix equal parts of water and vinegar in a spray bottle, and add a few drops of dish soap. Spray this solution on surfaces where gnats are present. The gnats will be attracted to the scent and will be killed upon contact with the soapy water.

5. Lemon Spray

The scent of lemon repels gnats. Create a natural gnat repellent by mixing lemon juice with water and spraying it around areas where gnats are present.

6. Essential Oils

Certain essential oils have repellent properties that can help keep gnats away. Peppermint, eucalyptus, lavender, and citronella oils are known to be effective. Dilute a few drops of the oil in water and spray it around doorways, windows, and outdoor areas.

7. Herb Plants

Planting herbs like basil, mint, and rosemary around your home and garden can deter gnats due to their strong scents.

8. Flypaper Strips

Hang up flypaper strips in areas where gnats are a problem. The sticky surface will trap the gnats when they come in contact with it.

9. Cinnamon

Sprinkle cinnamon powder around areas where gnats are present. The strong smell can deter them from coming near.

10. Vacuuming

Use a vacuum cleaner to suck up adult gnats and their larvae from surfaces and indoor plants.

11. Keep Things Dry

Gnats are attracted to moisture. Wipe down wet surfaces, fix leaks, and avoid overwatering indoor plants to reduce gnat attraction.

Chemical Solutions For Gnat Infestations

Chemical solutions can provide effective and fast-acting methods to control and eliminate these pests when facing a persistent gnat infestation. Here are some chemical solutions commonly used to combat gnat infestations:

1. Insecticides

Insecticides formulated specifically for gnats can be applied as sprays or foggers. These products contain chemicals that kill adult gnats on contact. Follow the instructions on the product label carefully and use them in well-ventilated areas.

2. Larvicides

To target gnat larvae, larvicides can be applied to areas where gnats breeds, such as standing water or moist soil. These chemicals disrupt larval development, preventing them from reaching adulthood.

3. Biological Control Agents

Beneficial nematodes and certain bacteria, like Bacillus thuringiensis var. israelensis (Bti), are used as natural biological control agents. They target gnat larvae in their breeding sites without harming other beneficial insects or humans.

4. Fly Strips And Traps

Sticky fly strips or traps can be effective in catching adult gnats. These traps use adhesive surfaces to capture gnats when they come into contact with the strip or trap.

5. Indoor Insect Foggers

In cases of severe infestations, indoor insect foggers (also known as “bug bombs”) can be used. These foggers release insecticides in aerosol form, filling the room and reaching gnats hiding in cracks and crevices.

6. Residual Sprays

Residual insecticides can be applied to surfaces where gnats rest or congregate. These chemicals provide longer-lasting protection against gnats as they continue to work for an extended period.

7. Electric Insect Zappers

Electric insect zappers attract gnats and other flying insects with UV light and then electrocute them when they come into contact with the grid.

When using chemical solutions, it’s essential to take safety precautions and follow the instructions provided on the product labels. Consider the following tips:

  • When applying insecticides, wear appropriate protective gear, such as gloves and masks.
  • Keep children and pets away from treated areas until the chemicals have dried or the fog has dissipated.
  • Ventilate indoor spaces after using insecticides to allow fresh air circulation.
  • Avoid using insecticides near food preparation areas or surfaces where food is stored.
  • Dispose of empty insecticide containers properly, following local waste disposal regulations.

Dealing With Gnats In Specific Areas

Dealing with gnats in specific areas requires targeted approaches. Here’s how you can handle them in different places:


  • Identify And Eliminate The Source: Check for any overripe fruits, vegetables, or food spills that may be attracting gnats. Discard them properly.
  • Clean Surfaces Regularly: Wipe down countertops, sinks, and other surfaces to remove any food residues that might be attracting gnats.
  • Securely Cover Trash Bins: Make sure your trash bins have tight-fitting lids to prevent gnats from getting inside.
  • Fix Leaks: Gnats are attracted to moisture, so fix any leaky faucets or pipes in the kitchen.


  • Keep It Dry: Moisture attracts gnats, so ensure your bathroom stays dry. Fix any leaks or water drips promptly.
