If you’re looking for a simple, natural-smelling way to make your home less inviting to insects, you may have heard about boiling bay leaves. Bay leaves have a strong herbal aroma, and their essential oils contain compounds that have shown insect-repellent activity in some laboratory studies.
However, boiling bay leaves should not be considered a guaranteed way to eliminate flies, mosquitoes, or cockroaches. For a real infestation, proper sanitation, removing standing water, sealing entry points, and using appropriate pest-control methods are much more reliable.
What You Need
- 8–10 dried bay leaves
- 3 cups water
- 1 small saucepan
- Heat-safe bowl or container
How to Make Bay Leaf Steam
1. Add the Bay Leaves
Place the dried bay leaves in a small saucepan and add 3 cups of water.
2. Simmer
Bring the water to a gentle boil, then reduce the heat and simmer for 10–15 minutes.
As the leaves simmer, their aroma will become stronger.
3. Let the Aroma Spread
Turn off the heat and allow the pot to cool slightly. You can leave it in a safe location while the aroma is noticeable.
Never leave a hot pan unattended, and keep it away from children and pets.
Why Do People Use Bay Leaves?
Bay leaves contain aromatic compounds such as 1,8-cineole and other essential oils. Some research has investigated bay-leaf compounds for insect-repellent or insecticidal properties, but that doesn’t mean that simply boiling leaves will eliminate an infestation inside a home.
The strong scent may make certain areas less appealing to some insects, but results can vary considerably.
More Effective Ways to Reduce Household Pests
For flies:
- Keep food covered.
- Empty garbage regularly.
- Clean spills and food residue quickly.
- Keep doors and windows screened where possible.
For mosquitoes:
- Remove standing water from containers, plant trays, and outdoor areas.
- Keep water-storage containers covered.
- Use window screens and appropriate mosquito protection.
For cockroaches:
- Keep food in sealed containers.
- Clean crumbs and grease promptly.
- Fix leaks and reduce sources of moisture.
- Seal cracks and gaps around walls, pipes, and doors.
- Use appropriate cockroach baits or professional pest control for persistent infestations.
Important Safety Note
Don’t drink bay-leaf water prepared for pest purposes, and don’t spray concentrated herbal preparations onto food, skin, or surfaces without knowing that they are safe for that use.
Also, boiling bay leaves produces steam and heat, so use normal kitchen safety precautions.
Final Thoughts
Boiling bay leaves can create a pleasant, strong herbal aroma and may offer some limited repellent effect, but it isn’t a proven replacement for effective pest-control measures. If flies, mosquitoes, or cockroaches are repeatedly appearing in your home, identifying and removing their food, water, and breeding sources is the best place to start.
