How to Deter Ants From Your Garden (or Anywhere) Using Coffee Grounds

Posted on Nov 7 2011 - 2:12am by Mike Lieberman

There has been a bit of an issue on my balcony garden lately with some ants. One of the swiss chard containers dried up and ants have gotten to it. I’ve been using coffee grounds to help deter them.

I’m not sure why exactly this works, but when the ants go near the grounds, they freak out and won’t cross them.

The first thing that I did was line the bottom of the container with the grounds. Then I had to follow the trail of ants to where they were going, which was into holes that were at the bottom of one of the rails.

A few coffee grounds were sprinkled around the rail, but also into the holes which the ants were using. After grounds were sprinkled into one of them, I watched as they went to the next and filled that one too. Grounds were put directly into the holes, otherwise they would just go around it.

Since putting the grounds down, I’ve definitely noticed a decrease in the ants.

Bonus Tip: If you don’t drink coffee, you can hit up your local coffee shop or cafe. If you ask, they will usually give you the grounds for free.

What are some other ways to deter ants from your garden?
