To get rid of rats in the garden, remove food sources, clear clutter, seal burrows, and set snap or live traps near active areas. For persistent infestations, use natural deterrents like peppermint oil or cayenne pepper, and call a professional if signs continue after two weeks. Rats can become a serious health risk fast — they’re not just a nuisance. They’ll infest outdoor areas just as readily as your house, and knowing how to get rid of rats in the garden before numbers build is the difference between a quick fix and a full infestation.
This guide from Fantastic Pest Control covers the most common questions and explains exactly how to get rid of rats in the garden — from the first signs to long-term prevention.
TL;DR
- The brown rat is the UK’s most common garden rat — it burrows, gnaws, and breeds rapidly if left unchecked.
- Rats are attracted to gardens that offer food (pet food, compost, fallen fruit), water, and shelter (woodpiles, decking, sheds).
- The fastest removal methods are snap traps set along walls near burrow entrances, baited with peanut butter, bacon, or chocolate.
- The most effective natural rat deterrents are peppermint oil, lavender, cayenne pepper, and garlic — applied near active areas and refreshed after rain.
- Seal all entry points with wire wool and expanding foam after removing rats — a rat can squeeze through a hole the size of a 50p coin.
- Call a professional pest controller if you still see fresh droppings or active burrows after two weeks of DIY treatment.

Signs of Rats in the Garden
The five key signs of rats in your garden are droppings, unusual pet behaviour, burrows in the ground, gnaw marks on structures, and greasy smear marks along walls or fences. Spot any one of these and it’s worth investigating further — spot two or more, and you almost certainly have an active infestation.
Rat droppings
Rat droppings are one of the clearest signs you’ve got a problem. They’re small, dark, and oval-shaped — about 10 mm long, like a large grain of rice. Check under bird feeders, pet food bowls, and compost bins, as these are the spots rats return to most.
Fresh droppings are black and slightly shiny. Older ones turn brown and crumble easily. If you’re finding fresh ones regularly, the rats are still active. The more you find, the bigger the infestation is likely to be.
Pets acting strangely
Your pets — especially dogs and cats — will often detect a rat invasion before you do. If your dog or cat is fixated on a particular corner of the garden, sniffing around burrows, fences, or the shed, or pawing at gaps in structures, take it seriously. They’re picking up on scent you can’t detect yet.
Burrows and tunnels
Rats — particularly the common brown rat — are skilled diggers. They create burrows in the ground with smooth, well-worn entrances, usually close to food sources like compost piles or rubbish bins, and often hidden under shrubs, garden sheds, or decking.
If you’re wondering whether rats make holes in the ground — yes, they do, and they go deep. Brown rat burrows typically reach 30–60 cm deep, with entrance holes 6–9 cm in diameter. If you spot a hole that size near your compost bin or shed base, it’s almost certainly a rat burrow.
Bite marks
Rats gnaw constantly to keep their teeth sharp. Rubber garden hoses, wooden structures, and plastic containers are common targets. The marks are small and jagged with a rough texture.
Beyond surface damage, rats may gnaw on electrical wires or irrigation pipes — which can cause water leaks or even electrical fires. Check any chewable material around your shed or compost bin, and inspect the shed frame itself for marks along the base and door edges.
Rat tracks and smear marks
Rats tend to use the same routes through your garden, which creates tracks in muddy or dusty areas. Look for small footprints, tail drag marks, or worn paths along fences and walls. Where rats repeatedly brush against a surface, their oily fur leaves behind greasy smear marks — a reliable sign of a regular run.
What to do if you see a rat in your garden
Don’t approach it. A single rat in daylight is often a sign the population is already large enough that competition for resources is pushing individuals out into the open. Check the surrounding area for burrow entrances, droppings, and gnaw marks before doing anything else. Then remove any obvious food sources — pet bowls, fallen fruit, unsealed bins — and set a snap trap near the burrow entrance that same day. If you’re seeing rats regularly in daylight, or find multiple active burrows, call a professional pest controller rather than trying to manage it alone.

How to Get Rid of Rats in the Garden
The most effective way to get rid of rats in the garden quickly is to combine two or three methods at once: remove whatever’s attracting them (food, water, shelter), set snap traps along walls near active burrows, and use natural deterrents to discourage them from returning. Rat poison works but carries risks near food crops and pets — natural and mechanical methods are the better starting point for most gardens.
- Remove all clutter: Rats are shy animals. They won’t settle somewhere they feel exposed. Clear everything that gives them cover — wood piles, unused plant pots, old garden equipment, and overgrown shrubs. Once you strip away the hiding places, you strip away their confidence. They’ll look elsewhere. Keep on top of this regularly. Cut the grass, trim hedges, and keep garden sheds tidy. The less cover available, the less attractive your garden is as a base.
- Live traps: Live traps catch rats without killing them — useful if you’re not certain what you’re dealing with. Bait with peanut butter or fruit, check frequently, and release any caught rat at least two miles from your home. If you leave a caught rat too long without checking, you’ll cause unnecessary stress, and the trap becomes counterproductive. Live traps work well for small-scale problems. For anything bigger, they’re not practical on their own.
- Snap traps: Snap traps remain one of the most reliable methods. They kill instantly with a spring-loaded mechanism. Position them along walls, close to burrow entrances — rats hug surfaces rather than crossing open ground, so placement matters.
- Try different baits: bacon, chocolate, and seeds all work. Leave unset traps in position for a few days first — this lets rats get comfortable with the object before you set and bait it.
- Flooding burrows: Flooding rat burrows forces rats out of their tunnels using water. It can work, but it’s a blunt approach. If the burrows are close to garden beds, you risk waterlogging roots and damaging plants. Identify tunnel entrances near food sources first, and treat this as a last resort rather than a first step.
- Natural repellents: The most effective natural rat deterrents for gardens are peppermint oil, lavender, cayenne pepper, and garlic — applied near active areas and refreshed after rain. These work because rats rely heavily on scent, and strong smells interfere with their ability to navigate and feel safe. Apply peppermint oil or lavender to cotton balls and place them near burrow entrances or along known runs. Mix cayenne pepper and garlic and sprinkle the combination around the perimeter. It won’t eliminate an existing infestation on its own, but it’s a solid deterrent once you’ve dealt with the main problem and want to keep rats from returning.
- Secure your food sources: Rats are opportunistic. They go where the food is. Secure everything in your garden — compost bins, pet food, fallen fruit. When composting, use a properly sealed bin and avoid putting dairy or meat in — both are strong attractants. Rat-proof compost bins are widely available and worth the investment if you’re an active composter. Check your compost pile regularly for signs of activity.

- Get equipped. You might come into contact with rat droppings or a dead rat, both of which are serious health hazards. Wear a face mask and rubber gloves before you start.
- Inspect thoroughly. Use a torch to check the base of the shed walls, the door frame, the roof junction, and the floor for gnaw marks and gaps. Rats can squeeze through a hole the size of a 50p coin, so look carefully — especially where different materials meet.
- Find and seal all holes. Block every gap you find with wire wool packed tightly into the hole, then seal over it with expanding foam. Wire wool alone isn’t enough — rats can pull it out. The combination is what holds.
- Install traps. Set snap traps or live traps inside the shed along walls and near any burrow entrances you found. Make the environment as inhospitable as possible. Check traps daily.

Call usHow to Keep Rats Away from the Garden
Once you’re certain you are rat-free, make a few changes to the garden to stop them coming back. Prevention is far easier than dealing with an established population.
Get a pet
If you don’t have a dog or an outdoor cat, now might be a good time to consider it. It’s not advisable to use your pets as pest control, but as a preventative measure, they can do a good job.
Plant your own pest control
Mint, peppermint, and lavender are among the best natural rat deterrents you can grow. Plant them around the perimeter of your garden or in pots near known hotspots — rats find the strong scent disorienting and tend to avoid areas where these plants grow densely. It’s low-effort prevention that keeps working season after season.
Put soft garden furnishings away
Keep patio furniture cushions in a secure cabinet when not in use. Rats love soft materials for nesting. Storing cushions away keeps them clean and removes a ready-made nesting resource.
Don’t keep woodpiles out in the open
Woodpiles are ideal rat cover. Store firewood at least 18 inches off the ground and at least four feet away from any structures. Keeping it away from your house and fences removes a natural bridge rats use to reach your home.
Keep food away from the lawn
Bird feeders and pet food bowls are two of the most reliable rat attractants in any garden. If you can avoid them, do. If you can’t, clean up spillage daily and bring bowls in overnight.

Shut the rubbish bin tightly
Bin locks are cheap and genuinely effective. Organic waste smells travel surprisingly far, and an unsecured bin will attract rats — and other wildlife — reliably.

Keep the garden tidy
The less clutter you have, the more inhospitable your garden is for rats. This includes the lawn itself — long grass gives rats cover to move around undetected, so mow it regularly.
Block access to the garden shed
Block holes in walls and around the door, and make sure there are no hollow spaces under the shed that could serve as a nesting spot. Wire wool and expanding foam together — not either alone — is the reliable fix.
Remove water sources if possible
It’s a tricky thing to manage, but removing sprinklers and birdbaths from your lawn genuinely helps. Unlike mice, rats need water every day — around 30–60 ml — and can’t survive long without it. Take away reliable water sources and your garden becomes a much less viable home for them.
Rats are very difficult to deal with once numbers build, so stay alert for the early signs. If you let an infestation get out of hand, you may find it hard to eliminate without professional rat pest control — and the Fantastic Pest Control team is always ready.

More on Rats in the Garden
Where do rats nest in the garden?
Rats nest in the safest, most sheltered spot they can find. In a garden, that’s usually a shed, a hollow space under decking or paving, a dense compost heap, or a cluttered corner with some overhead cover. They also use nearby sewers as access points and sometimes nest close to sewer exits. If you disturb a rat’s nest, expect the adults to scatter and potentially relocate close by.
Are garden rats dangerous?
Yes. Rats in the garden are a genuine health hazard — not just an inconvenience. They carry serious diseases that can infect people and pets through droppings, contaminated soil, or direct contact. They also gnaw on electrical cables and water pipes, which can cause structural damage or fire risk. Don’t wait to see how bad it gets.
What diseases do rodents carry?
Rats, mice, and voles carry a range of rodent-borne diseases, including salmonella, leptospirosis, cryptosporidium, Hantavirus, and rat-bite fever. In the garden specifically, contaminated soil and plants can spread disease even without direct contact. Droppings, bites, and scratches are all transmission routes — wear gloves whenever you’re working near a known rat area.
What damage can rats cause in the garden?
Rats will eat fruit, vegetables, and stored produce — including anything in your shed. They’ll invade compost bins, gnaw through fences, shed doors, electrical wires, and water pipes, and dig burrows that create uneven, unstable ground across your lawn. The damage compounds quickly once a colony establishes itself.
Will rats go away on their own?
Rarely. Without removing their food, water, and shelter, a rat population won’t leave — it’ll grow. A pair of rats can produce dozens of offspring within a few months. Acting early, when you first notice signs, is far easier than managing an established colony.
How do you destroy a rat’s nest in the garden?
Wear rubber gloves and a face mask before you touch anything. Soak the nest area with a disinfectant solution and leave it for a few minutes before disturbing the material — this reduces the risk of airborne particles carrying disease. Bag all nesting material in a heavy-duty bag, then double-bag it before disposal. Seal the burrow entrance with wire wool and expanding foam once the nest is cleared.
Where do rats live in the winter? Do rats hibernate?
Rats will find a warm place to shelter during the cold months. Usually that means a house or outbuilding like a barn or shed. If they can’t get inside, they’ll make do with a well-insulated burrow close to a reliable food source.
Rats don’t hibernate. They stay active all winter, but they need to eat more to maintain body temperature — roughly twice their usual intake. That drives them to exploit human resources more aggressively in cold weather, which is why rat activity around homes and gardens often increases through autumn and winter.
In fact, rats are notoriously resilient in cold conditions. A garden that feels quiet in winter can still be harbouring an active colony. Keep checking for fresh droppings and burrow activity even when the temperatures drop.

Getting rid of rats in the garden comes down to three things: remove what’s attracting them, disrupt where they’re living, and block them from coming back. Start by cutting off food and water sources, then set snap traps along walls near active burrows. Use peppermint oil, lavender, or cayenne pepper as natural deterrents once the traps are in place. If you’re still seeing fresh droppings or new burrow activity after two weeks of consistent effort, that’s your signal to call in a professional. Catching it early makes all the difference.
It’s always smart to bring in professional help if your own efforts aren’t cutting it. Fantastic Pest Control provides tailored, professional rat control solutions to help you get your garden back safely and for good. The Fantastic Pest Control team is always ready.
In the garden, pests may not be as obvious as in the home — but they’re just as worth dealing with quickly.
Pests like rats, mice and cockroaches may appear in your house if you neglect cleaning and do not take out the trash on time. I’m surprised people live in filth and then wonder why their place became infested.
I live in Wales near mountains and the garden has holes for the water to flow but I’ve spotted a rat what can I do my garden is clean but next doors is overgrown and it’s rented
Rats are cutting my garden plants.
What has “rented” got to do with anything? Go and speak to your neighbour. Start a dialogue. They may be receptive, and they could even contact their landlord if the responsibility is the landlords. If they are obnoxious, speak to environmental health at your local council. House owners are, as a matter of fact, more likely to not take care of their gardens than those in rented or leased accommodation…just for your information.
No, I think what she meant was that in general homeowners take a little more care of their garden for obvious reasons. Why be argumentative just for the sake of it?
Renters don’t care for a property like their own. They also won’t want to pay any additional costs. Stop being offended by a general statement just because you might not fit that bill.
I like my garden to be wildlife friendly, That means I’m happy to see native mice around the place and have many good locations but rats are not native and not welcome, I’m looking for rat solutions that with not harm the mice, hedgehog, foxes and birds. So no poison. A good well trained rat dog seems to be the solution but most are trains to go for mice also as most people are dicks and won’t to live a dead lands. We are careful about food sources, small field mice don’t need your leftovers but still have two locations where rats have displaced the wildlife. I’m guessing between the bugs, bird eggs and even the mice and small rodents the rats are finding plenty to prey on.
