South Florida Gardening

Make your own natural pest deterrents to keep your garden free of aphids, mosquitoes, snails, and other harmful insects and animals.

Natural Pest Deterrent #1

Mix 1/4 cup of Murphy’s Oil Soap per gallon of water to kill and deter whiteflies, mites, aphids, scale and other nuisance pests. Apply with a spray bottle to both top and bottom of affected leaves and stems when sun is not shining brightly.

Natural Pest Deterrent #2

Mix together 1 teaspoon dish washing liquid, 1 cup of vegetable oil and 1 cup of rubbing alcohol. Add 2 teaspoons of this mixture to 1 cup of water and apply as for #1 above.

Safe Mosquito Repellent

Mosquitoes are very sensitive to certain scents, especially Chamomile and Eucalyptus. Both are easy to grow and both are used in dry flower arrangements and potpourri. To make mosquito repellent, take one ounce of green leaves from both plants and boil in a gallon of water, then strain the mixture and place it in the refrigerator. Before going outside, splash the mixture over your face and exposed parts of your body. You will enjoy the fresh, citrus smell and the mosquitoes will stay far away.

Snail Deterrent

If you are having a problem with snails or slugs, place crushed egg shells or course sand around the base of plants. Snails don’t like crawling over the sharp edges, and egg shells are good for the soil!

Essential Oils

These pure extracts make great natural pest deterrents, but they are very potent and should be diluted and used sparingly. Use with caution and avoid direct contact with skin, eyes and mucous membranes! Remember, if a little works well it doesn’t mean that more will work better! Use these oils for making tinctures, teas, cosmetics, massage oils, bath oils and salts, potpourri, candles, incense etc. Place a few drops on a cotton ball and put in cupboards to repel insects.
