Ladybirds are among the most helpful insects a gardener can welcome, according to plant pest expert Tessa Cobley, owner of Ladybird Plantcare. Their bright red wings and cute appearance may make them a favourite, but their real value lies in what they eat.
Why ladybirds are good for your garden
Cobley says these tiny beetles are one of the best natural helpers you can have outdoors. "Ladybirds are one of the best natural helpers you can have in your garden," she explains. "They feed on many common garden pests, helping to create a healthier balance outdoors and reducing the need for intervention like chemical control."
Although many gardeners worry when they spot insects near their crops or flowers, Cobley says ladybirds should not be a source of concern. She points out they are "an essential part of a thriving outdoor space". A single adult ladybird can eat dozens of aphids a day, and their larvae are even hungrier – working through hundreds of aphids before they reach adulthood. This makes them one of the most effective natural defences against sap-sucking pests.
How to attract ladybirds
If your garden is lacking these helpful insects, there are practical steps you can take. Cobley advises against removing every pest you find. "Ladybirds need a reliable food source, so don’t be too quick to remove every pest you see," she says. "Leaving a small number of aphids on less valuable plants can encourage ladybirds to visit and settle in your garden."
Planting the right flowers also helps. Ladybirds are particularly drawn to flat-topped, umbrella-shaped plants, including dill, fennel, coriander, yarrow, angelica and sweet alyssum, as well as bright yellow and orange flowers like marigolds and calendula.
Ladybirds can also be bought from specialist suppliers, but Cobley warns there is no guarantee they will stay if conditions are not favourable. "Like all wildlife, ladybirds will stay where they have access to food, shelter and a safe environment," she adds. "By making your garden a welcoming place for them, you’ll be rewarded with one of nature’s most helpful little garden visitors."
There are 47 types of ladybirds in the UK, varying in colour and number of spots, and non-native species can also be found here. All of them are considered beneficial overall and feed on the same pests regardless of their kind.
