Having moles and mice in your garden can be frustrating, as they can disrupt your plants and landscaping. Thankfully, there are effective and eco-friendly ways to deter these critters without harming them. Let’s explore some practical methods to keep your garden free of moles and mice.
- Repel Moles with Plants
Certain plants naturally repel moles due to their strong scents:
Marigolds: Their pungent smell is unappealing to moles, making them a natural deterrent.
Castor Beans: These plants are highly effective but should be used with caution as they are toxic if ingested.
Plant these along the borders of your garden to create a barrier.
- Use Castor Oil-Based Repellents
Moles dislike the smell of castor oil. Create a simple DIY mole repellent by mixing:

3 parts castor oil
1 part dish soap
Water to dilute the mixture
Spray this solution on mole tunnels and surrounding soil. Alternatively, you can purchase ready-made castor oil repellents for convenience.
- Eliminate Mice with Traps and Natural Deterrents
Mice can damage plants and spread disease. To manage them:
Use humane traps: Relocate captured mice far from your property.
Peppermint oil: Mice dislike its strong scent. Soak cotton balls in peppermint oil and place them near areas where mice are active.
Predatory scents: Sprinkle predator urine (available at garden stores) to scare off mice.
- Maintain a Clean Garden
A clutter-free garden reduces the chances of attracting moles and mice:
Remove debris and fallen fruits.
Regularly mow the lawn to deter moles from tunneling.
Store birdseed and pet food in sealed containers.
- Use Barriers and Physical Solutions
Wire mesh or hardware cloth: Install these underground around garden beds to prevent moles from tunneling.
Ultrasonic devices: Emit sounds that are unpleasant to rodents but inaudible to humans.
Final Thoughts
Keeping moles and mice out of your garden doesn’t have to involve harsh chemicals or inhumane practices. By planting natural repellents like marigolds and castor beans, using castor oil sprays, and maintaining a clean environment, you can enjoy a beautiful and pest-free garden.
