There’s nothing quite like the feeling of relaxation that comes with spending time on a patio on a warm summer’s day. The sun shining down, a gentle breeze rustling the leaves of the plants, and the sound of birds singing in the background – it’s the perfect setting to unwind and enjoy some quality time with family and friends. However, for many of us, there’s one unwelcome guest that can quickly ruin the ambiance: ants.

Ants on the Patio: A Common Problem
Ants can be a nuisance, to say the least. They’re attracted to sweet or sticky substances, and once they’ve found a source of food, they can quickly multiply and become a problem. But did you know that there’s a natural way to keep ants at bay without resorting to chemical pesticides? It’s true, and it involves using certain plants that repel ants. In this article, we’ll explore the top 11 plants that can help keep your patio ant-free this summer.
The Science Behind Ant-Repelling Plants
So, how do these plants work? The answer lies in the chemical compounds they produce, which are often found in the plant’s essential oils. These oils can be toxic to ants, or they can simply confuse them, making it difficult for them to navigate. For example, European pennyroyal (Mentha pulegium) contains a compound called pulegone, which is known to repel ants. The strong scent of pennyroyal disorients ants’ navigating systems, making it difficult for them to find their way back to their colony.
European Pennyroyal: A Powerful Ant Repellent
European pennyroyal is a perennial plant that’s native to Europe and Asia. It’s a member of the mint family and has a strong, pungent scent that’s reminiscent of menthol and eucalyptus. This plant is not only effective at repelling ants but also mosquitoes and other insects. It’s a low-growing plant that only reaches up to a foot high, making it perfect for growing in a pot. In fact, pennyroyal is often grown in containers because it can rapidly spread when planted in the ground.
One of the benefits of growing pennyroyal in a pot is that it’s easy to control its spread. You can simply prune it back regularly to keep it from getting too large. Additionally, pennyroyal prefers moist and damp conditions, making it a great choice for areas with high humidity. It’s also hardy in zones 5-9, although you can easily grow it in colder zones by overwintering the container in a warmer spot.

Not only does it have a calming effect on humans, but it’s also known to repel ants and other insects.
