If you’ve spent any time in the garden this spring, you may have noticed the quiet return of slugs and snails.
They have a way of appearing just as everything else is getting going — drawn to those fresh, tender new shoots.
One simple, natural way to discourage them is with a garlic spray.
Does Garlic Spray Really Work for slugs?
In short — yes, but not in a dramatic, instant way.
Garlic spray doesn’t kill slugs and snails. Instead, it works by making plants smell and taste unappealing to them. Slugs rely heavily on their sense of smell, and strong scents like garlic can disrupt that, encouraging them to move elsewhere.
You’re unlikely to see an overnight transformation, but with regular use, it can make a noticeable difference — especially when plants are young and most vulnerable.
Like many things in the garden, it works best as part of a gentle, balanced approach.
Keeping plants healthy, avoiding overly damp conditions where possible, and applying deterrents like garlic spray all help to tip things in your favour.
And perhaps most importantly, it allows you to protect your plants without resorting to harsher methods — something that feels much more in keeping with working alongside the garden, rather than against it.
A Simple Garlic Spray Recipe
You’ll need:
2 whole bulbs of garlic
1 litre of water
A spray bottle
Method:
Crush the garlic cloves (no need to peel them perfectly).
Add to a pan with the water and bring to the boil.
Simmer gently for around 10–15 minutes.
Leave to cool completely.
Strain the liquid and pour into a spray bottle.
That’s it — simple and surprisingly effective.
How to Use It
Spray the solution onto the leaves of vulnerable plants, especially:
young shoots
seedlings
soft, leafy growth
It’s best applied:
in the early morning or evening
after rain (as it will wash off)
every few days when slug activity is high
A Gentle Approach
Garlic spray doesn’t eliminate slugs and snails, but it helps to tip the balance in your favour — making your plants less tempting while still working with the natural rhythm of the garden.
And like many things in gardening, it’s not about control. It’s about small interventions, applied at the right moment.
A seasonal note
I’ve started using garlic spray again recently as part of my April garden routine. If you’d like to read more about what’s happening in the garden right now, you might enjoy:
