How to Get Rid of Flies and Cockroaches Naturally …Without Harsh Chemicals
Flies and cockroaches aren’t just annoying — they can carry bacteria and contaminate food surfaces. While chemical pesticides may work quickly, they often come with strong odors, health concerns, and environmental risks.
The good news? You can reduce or eliminate these pests using simple, natural ingredients you may already have at home.
Here are several effective remedies that can help drive away flies and cockroaches — often within an hour.
1. Onion and Baking Soda Mixture
This simple combination works as a natural repellent, especially in kitchens and damp areas.
What You’ll Need:
- 1 medium onion
- 1 teaspoon baking soda
How to Prepare:
- Finely chop the onion.
- Mix it with baking soda to form a paste.
How to Use:
Place small amounts of the mixture in shallow lids or containers. Set them in areas where pests are active:
- Under sinks
- Near trash bins
- Behind appliances
- In kitchen corners
The strong onion odor combined with baking soda helps repel insects quickly.
2. Apple Cider Vinegar Fly Trap
Flies are strongly attracted to the smell of fermentation. This trap uses that to your advantage.
What You’ll Need:
- Apple cider vinegar
- A few drops of dish soap
- Small bowl or jar
- Plastic wrap
- Rubber band
- Toothpick
How to Prepare:
- Fill the bowl halfway with apple cider vinegar.
- Add a few drops of dish soap (this breaks surface tension so flies sink).
- Cover with plastic wrap and secure with a rubber band.
- Poke small holes in the top.
How to Use:
Place the trap where flies gather. They’ll enter through the holes and become trapped inside.
3. Bay Leaf and Clove Spray
Strong-smelling herbs naturally repel many insects.
What You’ll Need:
- 10–15 bay leaves
- 10–15 whole cloves
- 2 cups water
How to Prepare:
- Boil the water.
- Add bay leaves and cloves.
- Simmer for about an hour.
- Cool, strain, and pour into a spray bottle.
How to Use:
Spray around:
- Baseboards
- Cabinets
- Entry points
- Under sinks
The aroma deters both flies and cockroaches.
4. Baking Soda and Sugar Bait (For Cockroaches)
This is a common natural control method.
What You’ll Need:
- Equal parts baking soda and sugar
How to Prepare:
Mix thoroughly.
How to Use:
Sprinkle the mixture in areas where roaches travel.
The sugar attracts them, and the baking soda disrupts their digestive system.
5. Essential Oil Repellent Spray
Certain essential oils naturally repel insects.
Effective Oils:
- Peppermint
- Eucalyptus
- Lavender
What You’ll Need:
- 1 cup water
- 10–15 drops essential oil
- Spray bottle
How to Prepare:
Mix and shake well before each use.
How to Use:
Spray around:
- Windows
- Door frames
- Cracks and crevices
- Kitchen cabinets
Reapply daily for best results.
6. Lemon and Clove Repellent
This classic method works especially well against flies.
What You’ll Need:
- 1 lemon
- A handful of whole cloves
How to Prepare:
- Cut the lemon in half.
- Insert several cloves into each half.
How to Use:
Place the lemon halves where flies are active. The scent combination acts as a natural deterrent.
Prevention Is Key
Natural remedies work best when combined with proper hygiene and prevention.
To reduce infestations:
- Take garbage out regularly
- Wipe up spills immediately
- Store food in airtight containers
- Clean drains frequently
- Seal cracks and gaps around doors and walls
Pests are drawn to food, moisture, and shelter. Remove those, and you remove the attraction.
