How to Attract Insects to Your Garden and Build a Healthier Plot

A garden without insects is a garden in trouble. They pollinate the flowers, control the pests, break down organic matter, and feed the birds and small mammals that follow them up the food chain. The more insects your garden supports, the healthier everything else in it becomes.   Attracting them is mostly about giving them what they need year-round: nectar, pollen, shelter, water, and a planting palette that suits a wide range of species. None of it requires turning your garden into a meadow.   Here's how to attract insects to your garden through design choices that still look intentional.  

Why insects matter to your garden

A healthy population of insects is the foundation of a functional garden. Without them, pollination drops, pest species multiply unchecked, and the soil loses one of its main sources of organic matter.   Insects in your garden:  

• Pollinate flowering plants, including most fruit and vegetable crops you might grow.

• Control pest species through predatory insects like ladybirds, lacewings and hoverflies that eat aphids and other plant-damaging species.

• Decompose organic matter, breaking down leaves, dead wood and plant debris into usable soil.

• Feed birds, bats, hedgehogs and amphibians, which means a garden with more insects also tends to have more visible wildlife of every other kind.

• Aerate and improve soil, particularly through ground beetles and earthworm activity in the upper layers.

• Signal a healthy ecosystem, since insect diversity is one of the clearest indicators of garden health.   The RHS guidance on encouraging wildlife covers the ecological case in detail.  

How to attract insects to your garden

To attract insects to your garden, plant a wide range of flowering species that bloom across every season, leave some areas of grass and weeds unmanaged, add a shallow water source, avoid using pesticides, and provide nesting habitat through log piles, bare soil and dead plant stems.   The detail matters. Each of the following is worth doing on its own, but the gardens that genuinely buzz with life do most or all of them together.  

Plant for year-round nectar and pollen

Many insects emerge in early spring and remain active until the first hard frosts. A garden that flowers from March to October supports far more species than one that peaks in June and dies back.   Plant a sequence: hellebores, crocuses and snowdrops for early spring; aquilegia, geraniums and salvia for early summer; echinacea, verbena bonariensis and rudbeckia for late summer; ivy and sedum for autumn. The gap most gardens have is in late winter and early spring, which is when emerging queen bumblebees most need food.  

Choose plants that insects actually use

Many ornamental cultivars have been bred for show rather than for nectar, and produce little usable food. Double-flowered varieties are particularly bad, as the extra petals block insect access to the nectar.   Single-flowered varieties of any plant family will outperform their double-flowered equivalents. Native species are generally the most reliable for British insects, but well-chosen non-natives like lavender, salvia and verbena are excellent additions and extend the flowering season.

Leave wild corners and longer grass

A neat, fully-mown lawn supports almost no insect life. A small area of longer grass, even one or two square metres, transforms a garden's insect population. Native grasses, clover and self-seeded wildflowers between blades all provide food and shelter.   You don't need to commit to a full meadow. Leaving the edges of the lawn uncut, mowing one area every three or four weeks rather than every week, and tolerating a few dandelions and white clover patches makes a noticeable difference within a single season.  

Add a shallow water source

Insects drink. Bees, butterflies, hoverflies and wasps all need water in summer, and most insects can't safely land in a deep pond or a steep-sided bird bath.   A shallow dish with stones for insects to perch on, a saucer kept topped up beside a flowering border, or a pebble-filled tray near a vegetable patch all work. A small wildlife pond with sloping sides is the gold standard, but a saucer of water does the basic job.  

Provide habitat for nesting and shelter

Most solitary bees nest in hollow stems, exposed soil or undisturbed wood. Ladybirds overwinter in dense plant litter. Lacewings shelter in hollow stems through winter.   Specific habitats worth including: a log pile in a shady corner, a small patch of bare or sparsely-planted soil for ground-nesting bees, dead plant stems left standing through winter rather than cut back in autumn, and a purpose-built insect hotel if you want to make the effort visible.  

Stop using pesticides

The single biggest gain in an insect-friendly garden is removing chemical pesticides. Broad-spectrum sprays kill beneficial insects alongside pest species, often more efficiently, because beneficials are usually more active in open flowers where the spray lands.   Aphid outbreaks resolve themselves once ladybird and lacewing populations recover. Caterpillar damage on brassicas can be managed with netting. Slugs and snails are best controlled by encouraging frogs, ground beetles and birds, all of which need an insect-rich garden to thrive in the first place.  

Plant for specific insect groups

Different insect groups prefer different flower shapes. Bumblebees favour tubular flowers like foxglove, salvia and aquilegia. Honeybees go for open, shallow flowers like apple blossom and lavender. Butterflies prefer flat landing pads with deep nectar wells, like buddleja, verbena bonariensis and echinacea. Hoverflies need open, easy-access flowers like fennel, marigold and yarrow.   A garden that supports all four groups will also support most of the smaller, less visible insects that quietly do most of the ecological work.  

Best plants for attracting insects to your garden

The best plants for attracting insects to a UK garden combine year-round flowering, easy nectar access and species variety. A typical insect-friendly planting palette I'd recommend:  

• Early spring: Hellebores, Galanthus (snowdrops), Crocus, Pulmonaria, Mahonia

• Late spring: Aquilegia, Geum, Salvia nemorosa 'Caradonna', single-flowered tulips, Centaurea

• Early summer: Lavandula angustifolia, hardy Geranium, Foxglove (Digitalis), Catmint (Nepeta), Achillea

• Late summer: Echinacea purpurea, Verbena bonariensis, Rudbeckia, Helenium, Eryngium

• Autumn: Sedum 'Autumn Joy', single-flowered Dahlias, Aster, Persicaria amplexicaulis

• Winter and late autumn: Hedera helix (ivy, when in flower), Sarcococca, winter-flowering Mahonia   Plant in groups of three, five or seven for each species. A single specimen scattered through a border is much less useful to insects than a generous clump they can move between.  

What about unwanted insects?

Building a garden that attracts beneficial insects doesn't mean tolerating every species that turns up. Some insects damage plants, structures or stored food, and a small number become genuine pest problems that justify professional help.   The distinction matters. Wasps nesting in a roof eave aren't pollinators you want to encourage in that location. Carpenter bees boring into timber decking can cause structural damage over time. Cluster flies in a loft, ants under a patio, or a wasp nest near a back door are situations where a specialist pest control service is the right call, rather than a broad-spectrum home spray that risks killing the bees, ladybirds and hoverflies you've worked to attract.   The general principle: design the garden for beneficial insects, and deal with unwanted ones surgically where they cause real problems.  

Plant borders designed to attract insects

The most insect-friendly garden is one where the borders are planted with pollinator species from the start. A border that's pretty in May but bare for the other eleven months is no good to the bumblebees emerging in March or the hoverflies still active in October.   If you're starting from scratch and want a structured planting scheme to work from, my free border design templates for UK gardens include several wildlife-friendly schemes with plant lists you can take straight to the garden centre. The pollinator border template is the obvious place to start, but the cottage and naturalistic Scandinavian schemes both support a wide range of insects too.  

Want a garden designed for biodiversity?

A genuinely insect-rich garden doesn't happen by accident. The planting, the layout, the wild corners, the water source and the materials all need to be planned together so the garden looks designed rather than neglected.   I design gardens across London, Kent and the South East, including garden design in Croydon and the surrounding boroughs. Every project starts with a free site visit and a careful conversation about how you want to use the garden, including how biodiverse you want it to be.
