How to Kill Flies: 10 Proven Methods That Actually Work

Flies are not just annoying—they can carry germs, contaminate food, and quickly multiply in your home or yard. If you’re searching for how to kill flies effectively, you’re in the right place. In this blog, we’ll share 10 powerful and safe ways to eliminate flies using both natural and chemical methods.

Whether you’re dealing with houseflies, fruit flies, or outdoor pests, this guide covers everything you need to know.

Why Is It Important to Kill Flies?

Flies may seem harmless, but they are known to spread diseases like:

  • Salmonella
  • E. coli
  • Cholera
  • Typhoid fever

They breed in garbage, feces, and decaying matter—then land on your food and surfaces. That’s why controlling and killing flies is essential for a clean and healthy home.

1. Use a Fly Swatter (Classic but Effective)

Sometimes, the old-school method works best. Keep a fly swatter handy in your kitchen or patio to take out flies quickly. Aim for a quick, controlled swing—flies have fast reflexes!

Best For: Single flies indoors.

2. Set Up Vinegar and Dish Soap Traps

This natural method is perfect for fruit flies and small houseflies:

  • Fill a bowl with apple cider vinegar.
  • Add a few drops of dish soap.
  • Cover with plastic wrap and poke small holes.

The scent attracts flies, and the dish soap breaks surface tension so they drown.

Best For: Kitchens and near fruit bowls.

3. Use Fly Paper or Sticky Traps

Hang sticky fly traps in problem areas—especially near windows or doors. These traps contain attractants that lure flies and hold them in place.

Best For: High-traffic fly areas like porches, patios, and pantries.

4. Install an Electric Fly Zapper

Electric fly zappers attract flies using UV light and kill them instantly. These devices are perfect for:

  • Backyards
  • Dining areas
  • Garages

Pro Tip: Choose one with a safety grid to protect pets and children.

5. Keep Your Home Clean

This might sound obvious, but prevention is key. Flies are attracted to:

  • Leftover food
  • Trash cans
  • Dirty dishes
  • Pet waste

Keep surfaces clean, take out the trash daily, and use sealed garbage bins to reduce fly breeding grounds.

6. Essential Oils as Natural Fly Repellents

Flies hate the scent of certain oils. Use a spray bottle with:

  • Water
  • A few drops of lavender, eucalyptus, peppermint, or citronella oil

Spray around windows, doors, and garbage areas to keep flies away naturally.

Bonus: Your home will smell amazing.

7. Use Chemical Fly Sprays (With Caution)

When infestations get out of hand, chemical sprays like Raid® or Ortho® Home Defense can provide quick relief. Always:

  • Follow the instructions
  • Use in well-ventilated areas
  • Keep away from pets and food

Use as a last resort or for outdoor areas.

8. Seal Entry Points

Check your doors, windows, and vents. Flies can slip through the tiniest openings. Use:

  • Weather stripping
  • Door sweeps
  • Window screens

🚪 Prevention is easier than extermination.

9. Lemon and Clove Natural Repellent

Slice a lemon and stick cloves into the flesh. Place it in kitchens or near entry points. This simple hack acts as a natural fly repellent with a pleasant aroma.

10. Hire Pest Control for Serious Infestations

If you’re facing a fly infestation that doesn’t go away with DIY solutions, it’s time to call a professional. Pest control experts can identify breeding sites and eliminate the problem at the source.

Best For: Large properties or recurring infestations.
