Summer in Greece is all about the sea, sunshine, and—let’s be honest—mosquitoes. Every year, the buzz around natural mosquito repellents gets louder, with DIY remedies popping up across social media feeds. One of the most popular? A lemon or lime sliced in half with a handful of cloves stuck into its juicy flesh. Word has it, this citrusy-clove combo is a natural insect repellent. But does it actually work, or is it just another sweet-smelling myth?

Let’s dig into the science.

The theory hinges on aroma. Cloves contain eugenol, a powerful essential oil with proven insect-repelling properties. Not just folk wisdom—lab studies back it up. In fact, eugenol is a common ingredient in many plant-based commercial repellents. The lemon, in this mix, acts more like a vehicle: it adds moisture and acidity that help release the eugenol into the air faster. Its own zesty scent may play a minor role, but science doesn’t give lemon much credit in the anti-mosquito department.

So… does it work?

In indoor spaces, it might offer mild relief. The cloves do emit eugenol, and that can slightly reduce mosquito activity nearby. But don’t expect it to be a shield against bites all night long. At best, it’s a pleasantly fragrant sidekick—not a solo warrior. Count on it alone, and you might find yourself scratching at 3 a.m. wondering why you didn’t grab the spray.

The effect fizzles fast outdoors. Scents dissipate quickly in open air, leaving you unprotected. Sure, it looks charming as a centerpiece and smells lovely, but your legs are still on the menu.
Still, there’s a silver lining: it’s 100% safe. No harsh chemicals, no cost, and nothing to lose by trying it.

Bottom line?

The lemon-and-clove trick isn’t a miracle cure. It won’t replace your trusted bug spray, but it is a safe, eco-friendly, and aromatic ally in your summer mosquito defense strategy.
