From the page: Garlic peel has power
Idea 7
Homemade pest repellent
Garlic sprays have been used since ancient cultivation to scare off aphids, whiteflies and mealybugs — precisely because of the sulfur that gives garlic its strong smell. That smell confuses insects' sense of smell and hinders their locating of the plant, working as a shield the plant itself cannot produce.
What you need
- Garlic peels from 5 to 6 heads (you can also use bruised cloves)
- 1 liter of water
- A blender or mortar and pestle
- 1 teaspoon of grated mild soap
- A clean spray bottle
How to make it
-
1
Blend the peels with half a liter of water until they turn into a pulp — grinding releases far more of the sulfur compounds than just soaking.
-
2
Let this mixture rest in a covered spot overnight, so the extract becomes well concentrated.
-
3
Strain with a fine cloth and mix in the rest of the water along with the mild soap — the soap makes the liquid stick to the leaves instead of running off.
-
4
Pour into the spray bottle and test on a single leaf first, waiting a day, because very sensitive plants may react poorly.
-
5
Spray in the late afternoon, on both sides of the leaves, where the pests hide — strong sun combined with soap can stain the leaves.
Finishing touches
Apply every 5 to 7 days while pests persist, and always after rain, which washes the product away. Store the rest in the fridge for up to a week, well sealed so the smell doesn't take over the fridge.
