Bay Leaves as a Natural Roach and Rat Deterrent
While no single method guarantees 100% pest-free living, one simple, natural, and widely used household trick can help deter both rats and cockroaches…
Bay leaves won’t get rid of roaches or rats. What they can do is make your kitchen a less appealing place for them to stop by in the first place, and that’s worth knowing before you reach for something harsher.

How Bay Leaves Work
| Property | Effect |
|---|---|
| Strong aroma | Rats and cockroaches both dislike the pungent, herbal scent, largely thanks to compounds like eugenol and cineole. |
| Non-toxic | Safe around pets and kids when used as directed, unlike most chemical repellents. |
| Long-lasting | Dried leaves hold their scent for months. |
One thing worth being upfront about: bay leaves repel, they don’t kill. They won’t wipe out pests that are already there, but they may convince new ones to look elsewhere.
Where to Put Them
More on where to use them, next page.
Kitchen and Pantry
- Inside cupboards and cabinets, tucked into the corners
- Behind appliances like the fridge, stove, or dishwasher
- On pantry shelves near dry goods
- Taped to the underside of the trash can lid
Elsewhere in the House
- Under sinks, where moisture draws pests in
- Near doors, windows, and baseboards
- In basements, garages, and storage areas
- Around pet food storage
How to Use Them
- Two or three whole dried leaves per spot
- Swap them out every two to three months, or sooner if the scent’s gone
- Crush them slightly first — it releases more of the smell
Why It Works, and Why It’s Not a Fix-All
Rats and roaches navigate mostly by smell, finding food, sensing danger, all of it. A strong, unfamiliar odor throws that off and makes a space less worth their time. But if pests are already established, bay leaves alone won’t solve it. They’re one piece of a bigger approach, not a replacement for one.
What Else Helps
| Method | How It Helps |
|---|---|
| Peppermint oil | Deters rodents and some insects |
| Cedar chips or oil | Repels moths, fleas, rodents |
| Food-grade diatomaceous earth | Damages the exoskeletons of crawling insects |
| Sealing cracks and gaps | Steel wool plus caulk keeps them from getting in at all |
| A genuinely clean kitchen | No crumbs, no food source |
| Regular trash pickup | Removes what draws them in |
| Airtight containers for dry goods | Nothing to smell, nothing to get into |
What Bay Leaves Won’t Do
They won’t kill an existing infestation, work as your only line of defense, repel every pest (some insects don’t care), or last forever. Replace them every couple of months.
When It’s Time to Call Someone
If you’re seeing droppings, nests, gnaw marks, or hearing scratching in the walls, that’s past the point where bay leaves help. Call a pest control professional if you’re seeing multiple rodents or roaches regularly, or if whatever you’ve tried hasn’t worked after a few weeks.
Worth Doing Anyway
Bay leaves are cheap, safe, and simple, and as part of a clean, well-sealed home they genuinely help keep pests from settling in. They’re not magic. But they smell good to us and bad to them, and that’s a reasonable trade for something that costs almost nothing.
