Martha Stewart Reveals Plant That Repels Mosquitoes: 'They Bypassed Me in a Wide Arc'

As the weather warms and mosquitoes begin to emerge, many are seeking effective ways to keep these bothersome insects at bay. This year, a surprising ally has emerged in the form of a common garden plant, championed by none other than lifestyle icon Martha Stewart. Stewart recently revealed on her Instagram that catnip has proven to be a remarkably effective natural repellent, significantly reducing mosquito presence around her home.

One summer I just planted catnip in the yard and the mosquitoes, who otherwise adore biting me, bypassed me in a wide arc.

Stewart's personal experience is compelling: she noted that after planting catnip in her yard, mosquitoes that typically targeted her began to avoid her entirely. This anecdotal evidence is supported by horticultural insights. Catnip contains a chemical compound, nepetalactone, found in its essential oils, which acts as a potent insect repellent. While other fragrant plants like lavender, sage, mint, and lemongrass can also help deter mosquitoes by interfering with their scent receptors, Stewart specifically highlighted the exceptional efficacy of catnip.

The strong scents produced by some garden plants can somewhat disrupt the scent receptors that mosquitoes use to find people, but just planting fragrant plants is not enough to completely drive them away.

For those without a green thumb or the time to maintain a garden, the benefits of catnip can still be harnessed. Experts suggest that crushing the leaves or burning the plant's twigs can release the repellent oils. Alternatively, essential oil-based sprays can be created from the plant. This natural approach offers a welcome alternative to chemical repellents, providing a simple, accessible, and environmentally friendly solution to a common summer nuisance, all thanks to Martha Stewart's discovery.

The key is in the plant's oils. They are found in the leaves, are very concentrated, and really repel mosquitoes. It's best to release them by crushing the leaves or burning the plant's twigs.
