1. Gather Your Materials
Grab a can of regular Coca Cola, a clean spray bottle, and a pair of gloves if you want to protect your hands.
You'll also want to make sure you’re in an area where you don't mind getting a little messy, because things could get sticky!
2. Prepare the Spray Bottle
Using a funnel (if you have one), pour the can of Coca Cola into your spray bottle.
If you're working with a large bottle, you can add a little bit of water to dilute it, but for most weeds, full-strength Coca Cola works perfectly.
The sugar and acidity in the Coke are what help to dry out and kill the weeds. It's like a mini science experiment right in your garden!

3. Apply to Weeds
Now that your spray bottle is ready, it’s time for the fun part—spraying those weeds!
Be sure to target the weeds directly. The Coca Cola works best when applied directly to the leaves and stems of the weeds.
You’ll want to spray thoroughly, covering as much of the weed as possible.
Keep in mind that this solution is non-selective, meaning it will kill any plant it touches, so be careful not to spray your precious flowers or garden veggies.
But Won’t It Attract Ants?
You’re not alone if your first thought after spraying Coca Cola is, “Won’t this turn my yard into an ant buffet?” The truth is, yes — the sugar in Coke can attract ants if it’s left sitting on the surface for too long or sprayed around edible plants or mulch-heavy areas.
Here’s what to do:
- Use it only on isolated weeds, like in cracks of pavement, gravel paths, or driveway edges — areas where ants are less likely to set up shop.
- Avoid spraying near your veggie beds or flowers.
- Follow up the next day with a quick rinse if you're seeing any sticky residue or insect activity.
Basically: treat it like spot treatment — not a blanket spray — and you’re in the clear!
4. Wait for the Magic to Happen
After spraying, give it some time to work. Within a few hours to a day, you’ll start noticing the weeds wilting and dying.
The Coca Cola’s high sugar content interferes with the weeds' water intake, causing them to dehydrate and die off. It's nature's way of saying, "goodbye weeds, hello healthy garden!"
