5 Clever Ways to Use Irish Spring Soap in Yard and Garden Spaces
If you’ve ever found yourself side-eyeing your garden beds and thinking, “Okay, who’s been snacking on my lettuce again?” — same. It turns out, using Irish Spring soap in the yard might be one of the weirdest but easiest little pest-control hacks you’ll actually want to try.
Here are five ways to use Irish Spring soap in the garden and around your outdoor spaces — all super easy, low-cost, and no gross sprays involved.
Why Use Irish Spring Soap in the Garden?
People have been using Irish Spring soap in the garden to keep critters at bay for ages. Deer, rabbits, squirrels, even some bugs — they can't stand the smell. It’s like a “Keep Out” sign they actually listen to. And unlike sprays that fade after a rain, soap sticks around (literally).
Plus, it’s cheap, easy to find, and smells a whole lot better than most outdoor deterrents.
Tools and Materials:
- 1 bar of Irish Spring Original Soap🧼
- Cheese grater (one you're okay using for outdoor projects)
- Small mesh bags or old socks
- Wooden garden stakes or bamboo skewers
- Hammer or mallet (for stakes)
- Spray bottle
- Hot water
- Small containers, plastic cups, or yogurt containers (for grated soap)
- Twine or string
- Optional: food processor if you’re not in the mood to grate by hand

Step-by-Step: How to Use Irish Spring Soap in Your Yard
Here’s how I’ve been using it around my yard and garden, with a few fun twists you can try too.
1. Grate and Scatter Around Garden Beds
Grab an old cheese grater and go to town on a bar of Irish Spring. (It’s oddly satisfying.) Once you've got a little pile of shavings, sprinkle them directly into your garden beds, along the perimeter of raised beds, or mix them into the mulch.
The smell is what does the heavy lifting here. It’s strong, fresh, and apparently super offensive if you’re a rabbit, deer, or squirrel. So if you’ve got sneaky snackers visiting your kale patch, this might help keep them out.
Bonus Tip: Reapply after a heavy rain or once the scent fades. It’s not a one-and-done situation.
2. Slip a Soap Bar into a Sock + Stake It
This is one of my favorite lazy-day hacks. Just drop a full bar, chunks (or a generous handful of shavings) into an old sock, tie it off, and nail or staple the sock to a wooden garden stake. Then pop the stake into the ground near the plants you’re trying to protect.
The smell carries surprisingly far, especially when the sun hits it, and it gives you a little extra coverage without getting soap in your soil. Great for flower beds, raised beds, or anywhere the wildlife seem to throw a party at night.
Where I use this: Right in the middle of my tomato plants — they were practically a bunny buffet last year.
3. Melt It and Spray It
Want to make your own garden-friendly pest spray? Just grate about half a bar of soap, pour it into a bowl of very hot water, stir until it dissolves, and let it cool. Then pour it into a spray bottle and mist your garden beds, patio, fences, or even the legs of your raised beds.
This works great for people who don’t want visible soap chunks sitting around the yard. Just make sure not to overdo it on delicate plants — this is more of a barrier spray, not something to drench your leaves in.
Where I like to spray: Along the fence line behind my garden and around the base of the shed — prime hiding spots for critters.
4. Put It Around Trees
If you’ve got fruit trees (or just trees that seem to attract curious wildlife), try grating some Irish Spring soap and sprinkling a ring around the base of each tree. It's especially helpful if deer tend to nibble on lower branches or new growth.
The scent helps deter them without needing sprays or fencing. It won’t harm your trees, but it will probably confuse a few nosey deer.
Tip: Reapply every couple of weeks, or after rain.
5. Sprinkle Along Your Foundation
This one’s for the spiders, ants, and other crawlies. Try sprinkling a thin line of grated soap along the foundation of your house — especially where garden beds or mulch meet your siding.
The smell creates a kind of invisible barrier that bugs (and some rodents) just don’t want to cross. Plus, it smells way better than any chemical alternative.
Where to target: Near basement windows, shed doors, or anywhere ants love to sneak in.
