Garlic can be mixed into a spray that will repel garden pests.
Garlic is an effective ingredient in a horticultural oil spray that works by smothering insects and mites. It can also be used as an ingredient in an all-purpose repellent spray. Does this Spark an idea?
Garlic Oil Spray
To make garlic oil spray, soak 3 ounces of minced garlic in 2 teaspoons of mineral oil for 24 hours. Combine the garlic and oil with 1 ounce of dishwashing liquid and 1 pint of water in a glass jar. To apply this as a spray, use 1 to 2 tablespoons of the garlic mixture for every pint of water.
All-purpose Spray
To make an all-purpose spray, combine six garlic cloves, one onion, one tablespoon cayenne pepper and one tablespoon biodegradable dish soap with a small amount of water and blend until the mixture is smooth. Add slightly less than a quart of water. Let the mixture steep for a day, strain and pour into a spray bottle and treat plants. The spray can be stored in a refrigerator for two weeks.
Pests Treated
Garlic sprays can be used to repel and kill whiteflies, aphids and fungus gnats. Roses, orchids, fruit trees, cucumbers, lettuce, peas and celery are some plants that often see their most prevalent pests deterred by garlic.
