It might sound a little odd at first, but Coca-Cola can actually be a handy helper in your garden. While it’s often linked to sugary drinks and weekend treats, this fizzy soda has a few tricks up its sleeve when it comes to plants and pests.
Instead of pouring that last bit down the drain, you can put it to good use outside. Gardeners have discovered creative ways to turn Coke into a pest repellent, compost booster, and even a wasp trap.
With its acidity and sugary content, this drink works surprisingly well in a few unexpected spots around your yard. If you’re curious about turning everyday items into garden solutions, this might be your new favorite garden hack.
Take a look at how this popular soda can do more than just fizz.
#1 Get Rid Of Slug

Like using the beer to attract slugs, you can make it by pouring some Coca-Cola into a low bowl overnight, and the snails and slugs will be attracted to it.
The acid in the soda will get rid of these pests. Choose the place where you find the slugs most in the garden and mark 2 to 3 spots.
#2 Repel Mealybugs

Mealybugs love to hide in the crevices of stems and leaves, but a light cola spray can help send them packing. Diet or sugar-free versions work best, especially when poured into a spray bottle.
Mist your plant gently until the leaves are damp, making sure to get underneath as well. Try it on non-delicate plants first to see how they respond. The pests hate it, and your plants might just breathe a sigh of relief.
#3 Make a Wasp Trap

Wasps and hornets can be a real nuisance when you’re trying to enjoy your garden. A bowl of Coke placed in an open corner acts like a magnet for these buzzing intruders. The sweet aroma lures them in, and they end up stuck in the liquid.
It’s a safe way to reduce wasp traffic without using harsh chemicals. Keep the bowl refreshed if you’re dealing with a bigger problem.
#4 Compost

Your compost pile loves a little extra help breaking things down, and Coca-Cola brings just the right mix of acidity and sugar. Pouring a small amount over the pile helps speed up decomposition by encouraging healthy microbial activity.
Use it when your compost needs a kick or when it feels too dry. Just be careful not to overdo it—moderation keeps things balanced. It’s an easy, unexpected way to help your pile thrive.
