How to Use Onions to Get Rid of Pests: Rats, Flies, Lice, Bugs, Lizards, Mosquitoes, and Cockroaches | February 8, 2025

Onions aren’t just a kitchen staple—they also serve as a natural and chemical-free solution to repel common household pests. The strong smell and natural compounds in onions can effectively deter rats, flies, lice, bugs, lizards, mosquitoes, and cockroaches. Here’s how you can use onions to keep these pests at bay:

1. Repelling Rats
Rats have a highly sensitive sense of smell, and they find the strong odor of onions unappealing.

How to Use:

Slice an onion and place it in areas where rats are likely to enter, such as near doors, behind appliances, or in pantry corners.
Remember to replace the onion slices every 1-2 days to maintain a fresh scent.
2. Keeping Flies Away
Flies dislike the pungent smell of onions, making them an effective repellent.

How to Use:

Place slices of raw onion near windows, doors, or anywhere flies gather.
For an extra repelling power, add a few drops of essential oils like peppermint or lavender around the onion slices.
3. Treating Lice Naturally
Onion juice is known for its effectiveness in treating head lice naturally, thanks to its sulfur compounds.

How to Use:

Blend a few onions and extract the juice.
Apply the juice directly to the scalp, leave it on for 30 minutes, and then rinse thoroughly.
Repeat once a week until the lice are gone.
4. Repelling Bugs and Beetles
