Dealing with Moles, Rabbits and Garden Pests

Read the damage before you reach for a deterrent

Half the battle with garden pests is working out exactly who is visiting. The damage each creature leaves is remarkably distinctive, and once you know the culprit you can choose a method that actually works instead of scattering vague deterrents around the borders.

• Moles: neat cones of fine, crumbly soil with no obvious hole, usually in bursts across a lawn or bed.
• Rabbits: stems bitten off at a clean, sharp angle, often close to the ground, plus bark stripped from young trees between roughly 30cm and 60cm.
• Deer: ragged, torn stems and stripped foliage much higher up, with hoof prints in soft ground.
• Pigeons and cabbage white caterpillars: shredded or lace-like brassica leaves, often with droppings nearby.
• Voles: shallow runnels through grass and bark gnawed right at ground level.

Take a torch out at dusk, or a walk first thing in the morning. Most culprits are creatures of habit, and seeing them confirms the diagnosis.

Moles: the honest truth about molehills

Moles are solitary, territorial insectivores. They do not eat your plants. A mole is following earthworms and grubs through damp, loose soil, and the molehills are simply the spoil heaps pushed out of the tunnels. The real damage is cosmetic: soil on paths and gravel, disturbed seedbeds, and lifted roots where a tunnel passes beneath a young plant.

Molehills do come with a silver lining. That soil is beautifully sieved and free of stones, perfect for topping up raised beds or mixing into potting compost. Rake it up before it dries and hardens.

Deterrence is imperfect. Vibration and sonic devices sometimes shift a mole a few metres down the plot, then stop working as the animal grows used to them. Moles favour moist, worm-rich ground, so improving drainage in one area and keeping the lawn a little drier through summer can make it less appealing than next door's paddock. Where a mole is genuinely wrecking a lawn or sports area, humane trapping by a competent person is legal in the UK, but it must be done properly and with care for the animal. In most gardens, tolerance plus a rake is the kindest and most sensible answer.

Rabbits: barriers are the only reliable answer

Every scented spray on the market is a delay, not a solution. If rabbits are a real presence, fencing is the answer.

• Height and gauge: minimum 1.05m of hexagonal wire netting, 25–31mm mesh. Smaller mesh stops young rabbits squeezing through.
• Buried skirt: run the base 30cm underground, or fold it outward along the ground and pin it down firmly. Rabbits dig, and so do badgers and foxes, so check for new gaps monthly.
• Rigid top: add a taut wire or timber rail along the top so the fence cannot be pushed down.
• Tree guards: spiral guards or mesh sleeves to 60cm on young fruit trees. A rabbit can ring-bark a sapling in a single night.
• Veg cages: a simple timber frame draped with fine mesh over raised beds keeps out rabbits, pigeons and butterflies in one go.

Also clear long grass, brambles and log piles along boundaries. Rabbits dislike crossing open ground, and removing nearby cover makes your plot far less attractive.

Tolerant planting and sacrificial crops

Nothing is truly rabbit-proof in a hard winter, but some plants are reliably left alone. The trick is to plant the vulnerable things close to the house and put the awkward, strongly scented or prickly plants at the boundary.

• Herbs and silver foliage: lavender, rosemary, thyme, sage, nepeta and artemisia.
• Unpalatable ornamentals: foxgloves, daffodils, alliums, hellebores, berberis, holly and viburnum.
• Robust vegetables: potatoes, broad beans, onions, garlic, leeks and rhubarb. Brassicas will always need netting.
• Sacrificial rows: a patch of lettuce or nasturtiums well away from the main veg plot draws attention elsewhere.

Encourage the predators that do the quiet work: a small pond for frogs, a sheet of corrugated metal for slow worms, log piles for hedgehogs and beetles, and dense native hedging for thrushes and sparrowhawks. A healthy population of ground beetles and hedgehogs will do more for your slug problem than any trap.

Humane deterrents: scent, sound and surprise

Deterrents work best when rotated, because animals quickly learn to ignore a single stimulus.

• Scent: homemade garlic and chilli sprays, or predator-scent granules. Reapply after rain and swap products every ten days or so.
• Sound and movement: rustling tape, chimes and a timer-set radio can unsettle rabbits and deer for a while.
• Water: motion-activated sprinklers are excellent for cats and deer, and harmless to everything else.
• Slugs: water in the morning rather than the evening, clear damp debris, and apply nematodes in spring when the soil has warmed.

Please avoid poisons and glue traps. They cause suffering, and anything that takes a poisoned slug or rodent can pass that poison up the food chain to owls, buzzards and hedgehogs.

Living well with a working countryside

Aim for a garden that gives a little and defends what matters. Keep a note of what gets hit and when, so next season you can plant accordingly. Rake molehills into the beds. Accept a nibbled lettuce or two. Then wrap the things you truly care about — the young apple trees, the winter greens, the cutting garden — in proper barriers that will last a decade.

That balance of tolerance and good fencing is what makes a moorland garden feel settled rather than besieged. The wildlife stays, the vegetables survive, and you spend your evenings enjoying the view rather than patrolling it.
