Explanation
Bay leaves do contain essential oils (like eugenol and cineole) that have a strong aroma which may repel some insects temporarily. When boiled, the steam carries these compounds into the air, which can make your kitchen or house less attractive to flies, mosquitoes, and even roaches for a short time.
Reality Check
- This method does not permanently eliminate pests. It only masks smells or creates an unpleasant environment for a while.
- Flies and mosquitoes may stay away briefly, but they can return once the scent fades.
- Cockroaches are tougher — the bay leaf smell may repel some, but it won’t kill them or keep them away long-term.
Safer & Effective Alternatives
- Flies & Mosquitoes
- Use citronella candles, lavender oil, or eucalyptus oil.
- Keep windows/doors closed or install screens.
- Cockroaches
- Baking soda mixed with sugar (natural bait).
- Boric acid powder in hidden corners.
- Keep kitchen dry and clean (roaches love moisture + crumbs).
- All Pests
- Seal cracks and food containers tightly.
- Empty trash frequently.
- Bottom line: Boiling bay leaves may help repel pests temporarily due to their aroma, but it’s not a permanent or guaranteed solution. For long-term control, combining natural repellents with cleanliness and proper sealing is much more effective.
