This post shares my tiny apartment balcony garden and all about how I made my DIY squirrel repellant spray for the cute but pesky squirrels who kept getting in to my garden!

My Balcony Garden & How to Make DIY Squirrel Repellant Spray

I absolutely love my apartment balcony garden. This is the first time we’ve have a balcony sunny enough to grow anything on, and I’ve definitely taken full advantage of it!

I have a vertical balcony garden I made that has herb pots clipped onto it and a bed of lettuce at the bottom. After my skinny pallet planter bit the dust, I bought this replacement planter and planted more lettuce seedlings.

I also have a cherry tomato plant, a jalapeno plant, a smaller planter with more herbs, and a few miscellaneous potted plants on the patio table. It’s my little apartment paradise!

Unfortunately, the approximately 1 million neighborhood squirrels agreed with me. THE SQUIRRELS LOVE MY GARDEN. They climb up the gutter next to our balcony, hop over, and dig into the soil. They typically don’t damage the plants, but they dig up seedlings and make a huge mess! I had to replant my lettuce seeds four times before I caved and bought chicken wire.

But after a few days of having chicken wire up and me thinking my plants were safe, the squirrels found their way in through the top of the chicken wire. I read online that squirrels hate the smell of cayenne pepper, so I tried just sprinkling that in my soil, but it didn’t do anything. They still dug holes and threw soil everywhere.

Eventually I decided to try my hand at a squirrel repellant spray. After I started spraying my soil with my DIY squirrel repellant spray, the squirrels starting staying away. In fact, the morning after I sprayed it, I saw a squirrel on our balcony, but it didn’t dig any holes! It just sniffed around and ran away. I’m hoping it’s because they hate the smell of my squirrel repellant and not just because they’ve run out of trinkets to bury.

Here’s what I used:

  • 8 cups water
  • 1 large onion, chopped
  • 1 jalapeno
  • Cayenne pepper, about a teaspoon
  • Pot, stove, strainer, spray bottle

And here’s how I made DIY squirrel repellant spray.

First step: Chop the onion and jalapeno. Make sure to leave the seeds in the mixture. Then add the onion, jalapeno, cayenne pepper, and water to a pot and bring to a boil. Let simmer for 20-30 minutes.

Second step: Let the mixture cool. Pour through a strainer so that only the liquid mixture makes it into the spray bottle. I didn’t want to waste the onions and jalapenos, so I added a bunch to some spicy stir fry chicken for dinner and saved the rest for another meal. But beware, they are s-p-i-c-y!

Spray the soil of your plants. The smell will hopefully ward off your tree rats and prevent them from digging holes and throwing soil everywhere. I didn’t spray any leaves because I didn’t have any problems with squirrels munching on the leaves.

Fingers crossed my plants stay green and my balcony stays clean!

Does this work for mice too? I live near agriculture and mice are a problem, but I don't want to use chemicals.

I'm sorry, but I haven't tried it on mice!

Great idea, I love wildlife but I love my vegetable garden more. We had to make a habenero oil spray to keep the deer from eating the leaves off of everything. We tried Irish spring but they're so hungry from our drought in California that even that didn't work for long.

I hope you get to enjoy some yummy veggies!

Oh I'm glad that worked! Our spray scared the squirrels right away...we've gotten plenty of lettuce, tomatoes, and jalapenos!!
