Attracting Bats to Waterside Gardens with Night-Scented Plants

There is something magical about a waterside garden at dusk: the light fading over the pond, the first pipistrelle flickering along the hedge, the plop of a Daubenton's bat skimming the surface. If you garden beside a river, canal, lake or even a modest wildlife pond, you already have the foundations of a bat-friendly haven. With a few night-scented plants and a thoughtful approach to lighting, you can turn your patch into a reliable dusk larder and commuting route.

Why Waterside Gardens Suit Bats

Water is a magnet for insects, and insects are what bats need. A single common pipistrelle can eat around 3,000 midges, mosquitoes and small moths in a night. Waterside gardens also offer drinking water — bats drink on the wing, swooping low to take a quick sip — and many species use rivers, canals and pond edges as dark corridors between roosts and feeding grounds. Daubenton's bat, in particular, hunts over calm open water, trawling insects from the surface with its large feet.

Plant a Night Larder

Night-scented flowers are the heart of the plan. They release their fragrance after dusk, drawing in moths and other nocturnal insects, which in turn bring in bats. Pale or white flowers also show up well in low light. Plant them in generous clumps rather than single specimens, and place some close to the water's edge or beside a seating area.

Evening primrose (Oenothera biennis) — tall, luminous yellow flowers that open in the evening.
Night-scented stock (Matthiola longipetala) — modest plants with an extraordinary clove-like perfume after dark.
Tobacco plant (Nicotiana sylvestris and N. alata) — white trumpets that glow at dusk and attract moths.
Sweet rocket (Hesperis matronalis) — cottage-garden favourite, scent strongest in the evening.
Honeysuckle (Lonicera periclymenum) — native climber, night-scented and a larval food plant for moths.
Night phlox (Zaluzianskya ovata) — low-growing, honey-scented, perfect for a pot by the door.
Nottingham catchfly (Silene nutans) — a wildflower that opens at night and feeds moths.

Do not forget the caterpillars. Moths need larval food plants: nettles, honeysuckle, evening primrose and native grasses. Leave a wild corner, avoid double-flowered varieties, and aim for a succession of bloom from late spring to autumn.

Light with a Light Touch

Lighting is the single biggest factor in whether bats use your garden. Most UK bats avoid brightly lit areas, and one white security light can deter them from a whole stretch of water. If you need light, choose warm white LEDs of 2700K or lower, or red LEDs, which bats seem to tolerate better. Keep the wattage low, fit hoods or shields so the beam points down, and use motion sensors and timers.

Never illuminate the water surface, mature trees, hedges or known roosts. Keep a dark corridor along the water's edge and across the garden, so bats can commute and feed without crossing a pool of light. Solar-powered floodlights are often the worst offenders: bright, cool white and on all night.

Manage the Water's Edge

Bats need a clear approach to drink. Keep a stretch of open water free from overhanging branches — three or four metres is plenty — and avoid netting over ponds, which can entangle bats. Leave shallow margins and plant native marginal species such as yellow flag iris, sedges and rushes; these support the midges, caddisflies and small moths that bats eat.

If you keep fish, keep them few. Large stocks of carp or goldfish graze on insect larvae and can leave the water lifeless. Avoid chemical treatments, fertilisers and insecticides anywhere near the water; run-off reduces insect numbers and can poison bats indirectly. A log pile or stone stack at the edge adds shelter for insects and other wildlife.

Roosts and Shelters

Bats need somewhere to roost as well as feed. Mature trees, old hedges, ivy-covered walls and gaps in buildings all provide roosts, but you can add purpose-built bat boxes. Choose untreated rough-sawn wood or woodcrete, with a crevice 2–3 cm wide, and mount it 3–5 metres up on a south or south-west facing wall or tree, free from clutter. Put up several boxes with different aspects; bats are choosy.

Keep cats indoors from dusk. Cats are significant predators of bats, especially near roosts and low over water. Remember that bats and their roosts are legally protected in the UK; if you suspect a roost, do not disturb it — seek advice from a licensed bat ecologist.

Dusk Watch and Seasonal Rhythm

In summer, common and soprano pipistrelles usually appear 20–30 minutes after sunset, flitting erratically along hedges and over the water. Daubenton's bats arrive later, flying fast and low, sometimes touching the surface. A heterodyne bat detector turns their echolocation into clicks and smacks you can hear; even without one, watch for silhouettes against the afterglow.

Leave seed heads and hollow stems over winter, and delay cutting back until late spring. Water is valuable all year, so keep a pond ice-free in cold spells if you can. With night-scented flowers, dark edges and a little patience, your waterside garden will become a dusk destination — for bats, moths and you.
