If your pride in your garden is being spoilt by pests like aphids, whiteflies and mosquitoes you know how frustrating they can be. These bugs can be extremely pervasive and difficult to get rid of. While many gardeners turn to intense chemical sprays to protect their plants, one expert says there is a more natural solution that will not only get rid of pests, but add a gorgeous splash of colour and scent to your garden.
Doug O’Connor, a garden expert, from DeerFencing.com, explains that certain flowering plants release compounds and scents that naturally deter insects. He said: “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.”
If you want to step your garden up and keep it clear of pests the first thing you need to plant is lavender.
Dough said: “Lavender’s strong aroma, which comes from natural oils like linalool, repels moths, fleas, and mosquitoes. It’s particularly effective when planted along paths, borders or near seating areas.”
Lavender thrives in sunny, well-drained areas, making it a great low-maintenance addition to most gardens.
Marigolds are another great addition – they are bright and colourful but also make a great companion plant to vegetables. This is because they contain a natural insecticide.
Doug said: “Marigolds contain a compound called pyrethrum — a natural insecticide. They’re especially effective when planted alongside vegetables like tomatoes or courgettes.”
They’re easy to grow, bloom for months, and make excellent companions in mixed planting beds or borders.
The third plant that can help stave off insects is one of the most effective – chrysanthemums are great at repelling insects thanks to their high pyrethrin content.
“Chrysanthemums repel everything from ants and lice to ticks and cockroaches,” says Doug. “Plus, they add bold colour to autumn gardens when most plants begin to fade.”
You can plant them near your doorways and windows to discourage bugs from flying into your home.
Last, but certainly not least – daffodils. Known for signalling the arrival of spring, daffodils also have insect-repelling benefits. While not as potent as marigolds or chrysanthemums, their alkaloid content deters certain pests like slugs, and their bulbs are unappetizing to rodents.
Doug said: “They’re low-effort and naturalise easily, meaning they’ll come back year after year with minimal care. Plus, they help protect more vulnerable plants nearby.”
