1. Peppermint oil
Rats hate the smell of peppermint oil, so it’s an effective way to drive them away. Moisten some cotton balls with 100 per cent pure peppermint oil and place them in various spots around the garden, including the garage and shed. Reapply the oil a couple of times a week.
Get some catnip from a garden centre and plant it in several spots around the garden. Be strategic with your planting and look for signs of rat activity like nests and pellet droppings.
3. Keep your garden clean
You can deter rats from setting up home in your garden by keeping it clean and tidy. Remove piles of wood and garden clippings; pick up any fallen fruit, berries or vegetables, and cut back overgrown areas.
4. Remove food and water sources
Rats will seek out any sources of food or water in your garden. Make sure your taps aren’t dripping and don’t use a bird bath. Remove bowls of pet food or water at night. If you like to compost, keep it secure and bury any organic material deep in the bin. Make sure lids are tightly closed on bins and don’t leave garbage bags outside for long periods.
5. Soil netting
If you want to protect a new garden from rats, lay a piece of netting just under the soil. This will prevent rats from burrowing and eating roots and bulbs. Determined rats may chew through the netting, so keep an eye out for it.
6. Sealing gaps
Rats will try to enter your home through any gaps or cracks in external walls. Use an appropriate sealant to block any nooks and crannies.
