Onions are not just for cooking; they can also serve as a natural and cost-effective solution to keep various pests at bay. Their potent smell and unique compounds make them an excellent option to deter pests like rats, flies, lice, bugs, lizards, mosquitoes, and cockroaches. Let’s explore how you can use onions to combat different types of pests effectively.
1. Rats ๐
Why It Works:
Rats are repelled by the strong, overpowering scent of onions, which can overwhelm their sensitive noses.
How to Use:
- Cut up a fresh onion into chunks.
- Position the onion slices in areas frequented by rats, such as corners, entry points, or near food storage locations.
- Remember to replace the onions daily for maximum effectiveness.
Caution:
Ensure onions are inaccessible to pets as they can be harmful to cats and dogs.
2. Flies ๐ฆ
Why It Works:
The sulfur compounds in onions act as a natural repellent for flies.
How to Use:
- Slice an onion and place it in a bowl of water.
- Enhance the repellent properties by adding a few drops of lemon juice.
- Put the bowl near windows, doors, or other fly-prone areas.
Optional Spray: - Create a spray by blending an onion with water and straining the liquid. Use it in fly-infested zones.
3. Lice ๐ง๐ง
Why It Works:
Onions contain sulfur that can suffocate lice and aid in breaking down their eggs.
How to Use:
- Make a paste by blending an onion and straining the juice.
- Apply the onion juice directly to the scalp, leaving it for 30 minutes.
- Thoroughly rinse and comb out the lice and nits. Repeat as necessary.
4. Bugs and Insects ๐
Why It Works:
The potent smell of onions deters bugs and insects effectively.
How to Use:
- Place chopped onions in bug-prone areas such as cabinets, under sinks, and near food containers.

5. Lizards ๐ฆ
Why It Works:
The strong odor of onions disrupts the sense of safety for lizards.
How to Use:
- Position onion slices near lizard-populated areas like window sills, corners, or behind furniture.
- Replace the onions every 2-3 days.
6. Mosquitoes ๐ฆ
Why It Works:
The pungent aroma of onions masks the scents that attract mosquitoes.
How to Use:
- Crush an onion and mix the juice with water.
- Spray the mixture in mosquito-prone sites like standing water areas, windows, and doorways.

7. Cockroaches ๐ชณ

The offensive smell of onions deters cockroaches from infested areas.
