People will be heading out to their gardens this weekend as the temperatures rise, but uninvited guests will also be making an appearance as the hot weather will see a surge in insects, with experts saying there will be plenty of wasps. If wasps decided to set up home in your home, removing a nest can cost around £250.

But experts say you can keep wasps out of your garden, and your home, using a common 49p plant.

Liam Cleary, outdoor plants expert at Old Railway Line Garden Centre, says planting lavender is a simple, affordable solution that looks great and keeps the wasps from hanging around your garden.

He said: “Wasps are highly sensitive to strong scents, and lavender is one they really don’t like. Planting it near seating areas, doorways, or patios can help mask the smells that attract them, like food, sugary drinks or perfumes.”

Why lavender keeps wasps away

Lavender contains essential oils like linalool and camphor, which give it that distinctive floral smell. While it’s pleasant to humans (and pollinators like bees and butterflies), it’s overwhelming to wasps, which rely heavily on scent to detect food.

It also happens to be one of the easiest and most rewarding plants to grow. It’s drought-tolerant, looks great in any outdoor space, and is available in compact pots for patios or larger varieties to border garden paths – just in time for National Lavender Day on July 9.

You can pick up a pot of lavender for £6, or lavender seeds for as little as 49p. Liam said: “It’s low maintenance, smells incredible, and keeps your garden feeling calm, all while helping you enjoy a wasp-free zone.”

How to get the best results:

• Choose a sunny spot: Lavender loves full sun and well-drained soil, so avoid shaded or damp areas

• Go for pots or raised planters: These make it easier to move the plants where needed, and work brilliantly on patios or balconies

• Don’t overwater: Lavender is drought-tolerant and prefers slightly dry conditions. Overwatering can cause it to wilt or rot

• Pair it with other natural deterrents: If you’re prone to wasp visits, try planting lavender alongside mint, thyme, or lemongrass for an extra layer of protection

Wasps become more aggressive from late June into August as their colonies grow and natural food sources decline, making them more likely to pester humans for sugary snacks and drinks.
