How to get rid of rats in the garden

Stop feeding wild birds and animals

Like all living things, rats need food, water and shelter to survive. Remove at least one of these from your garden or allotment and they are less likely to stay. Rats feed on grain and may be attracted to your garden by fallen food from bird feeders. Stop feeding birds if you suspect rats are visiting your garden, and secure chicken runs. Store bird and other animal food in secure containers, or stop feeding and focus on natural sources of seeds and berries.

Keep the garden tidy

Tidy gardens are less likely to attract rats as they provide less cover, but bear in mind that this could harm other wildlife, such as hedgehogs. Keep grass short, clear cluttered storage areas, remove rubbish and reduce overgrown areas, especially near fences or garden buildings.

Rats are ‘neo-phobic’, which means they have a fear of new things. They don’t like disruption to their territory, so place obstacles in their runs and move things around in the garden frequently.

Block access to decking

The space beneath decking is perfect for rats – it’s sheltered, hard to reach and food scraps can fall between the planks. Sweep up any fallen food after alfresco meals. Block access if possible or consider installing a patio instead, if the problem persists.

Block access to garden buildings

Protect your compost bin

Make your compost bin or heap uninviting – don’t add food scraps and keep it moist (which rats don’t like) by including plenty of green and brown materials. Watering the heap regularly can also deter them. Fixing chicken wire around the base of the bin can also help, as it prevents rats from being able to dig beneath the bin to climb inside. Turn the heap regularly but bear in mind that other wildlife uses compost heaps too. If rats have made a home in your bin, don’t use the compost on edible crops.

Need to update your compost bin? Our experts have tested a range of different types, so you can choose the best compost bin to suit your garden. Here’s a list of the Best Buys from that test, at a glance:

Keep an eye on crops

There’s not much you can do to keep rats off your crops. Rats will eat sweetcorn, pumpkins, squash, root vegetables and apples, so once harvested, store them somewhere secure. If you suspect that stored or growing crops have been nibbled by rats, don’t eat them. Rats also eat seeds, so store them securely.

�

Remove water sources

Rats can’t survive without water. While it’s not advisable to remove garden ponds or bird baths, removing other sources of water, including dripping taps, can help deter rats, Secure drains and add baffles to drainpipes.

Encourage predators

Rats form a substantial part of a fox’s diet, so – where possible – it’s a good idea to give foxes space to live in your garden or allotment, too. Pets can also deter rats, as they can be a disruptive force in the garden, making the rats less likely to stay. Some cats will kill and may even eat rats, but they are not as effective predators as foxes.

Control them

As an absolute last resort, you may consider taking stronger measures to control rats. Do this only after all other efforts to deter them have been exhausted, as poisons can harm other wildlife in your garden and can get into the wider environment. First, identify where the rats are living and feeding routes they take between them – in neighbouring gardens, too. Traps and poisons are sold at garden centres but must be used correctly – read the label. It’s better, and safer, to contact your local council or professional pest controller.

How to protect plants from rats

There’s not a lot you can do to deter rats from eating your vegetable crops, but it’s thought that regularly spraying peppermint oil on or near your crops will help to deter them. Rats hate the potent smell of peppermint oil and will stay away. Reapply the oil twice a week. Another strong smell is the plant catnip. Plant this in your borders and you may stop rates visiting.
