Slugs and aphids won't touch your garden if you grow 4 plants that 'repel everything'

Common garden pests like aphids, the sap-sucking insect, pesky mosquitoes and slugs can turn a glorious outdoor space into a gardener's nightmare, but these four plants could be your saving grace. While many people turn to chemical sprays in these desperate times of need, it turns out there is a more natural solution. Not to mention, it can spruce up your garden in the meantime.

A number of flowering plants release compounds and scents that can naturally deter insects, a garden expert from DeerFencing suggests. Doug O’Connor explained: “These plants aren’t just ornamental — they serve a vital purpose in keeping your garden healthier, naturally. With the right selections, you can create a vibrant space that’s both attractive and more resilient against pests.”

He has shared the four common plants you can use at home to repel unwanted insects, all while adding a touch of beauty to your outdoor space.

Lavender

Lavender is loved by many for its calming scent and natural uses in the beauty and wellness world, but it also happens to be a great flower for pest control. According to the gardening enthusiast, its strong aroma, which stems from natural oils like linalool, works to repel moths, fleas, and mosquitoes.

It's suggested that Lavender is particularly effective when planted along paths or borders near seating areas. The plant thrives in sunny, well-drained areas, which makes it incredibly low-maintenance, whatever level of experience you have with gardening.

Marigolds

Full of vibrancy and colour, marigolds make a great addition to any garden, but they're more than just decorative. Similar to lavender, their distinctive scent deters common garden pests like aphids, whiteflies, and even soil-dwelling nematodes.

Doug suggests that Marigolds contain a compound called pyrethrum, which acts as a natural insecticide and are particularly effective when planted beside vegetables such as tomatoes or courgettes. With easy-to-grow qualities and the ability to bloom for months on end, marigolds make a great companion mixed into planting beds and borders.

Chrysanthemums

Chrysanthemums are an often-overlooked plant despite being among the most effective insect-repelling flowers due to their high pyrethrin content. The gardening expert claims that this type of flower can repel anything, from ants and lice to ticks and cockroaches.

They add a bold touch of colour to autumn colours when most other plants begin to fade and are especially helpful when placed near doorways or windows, which helps to discourage insects from sneaking their way inside your home.

Daffodils

For many, daffodils are known for signalling the arrival of spring, but they also happen to have excellent insect-repelling benefits. While not as potent as marigolds or chrysanthemums, their alkaloid content works to deter certain pests like slugs, and their bulbs are unappetising to rodents.

The expert explained that they’re a low-effort plant that naturalises easily, meaning they’ll make a comeback year after year with very little care needed. Plus, they help protect other vulnerable plants nearby.

Doug O’Connor said: “Natural pest control doesn’t have to be complicated. These four flowering plants are widely available across the UK, require little maintenance, and add colour as well as protection to your outdoor spaces.

“Rather than relying on harsh sprays, which can harm pollinators and disrupt ecosystems, using companion planting gives gardeners a sustainable way to manage pests. It’s a win-win for biodiversity and your borders.”
