Your Guide To Buying Neem Oil
The fruit and seeds of the neem tree can be used to produce neem oil, which is useful for a number of purposes. It is a strong insect repellent, due to its strong, garlic odor. It also kills a number of insect pests (aphids, mites, beetles, and more), while not harming beneficial insects (butterflies, honeybees, and ladybugs). It is also useful in killing fungus that attacks garden plants. Finally, it even has uses in cosmetic products as well. It can be used for treating acne, as well as acting as a skin exfoliant. Here is a guide to some of the best neem oils on the market.
Types of Neem Oil
100% Pure Neem Oil: Neem oil alone has a very strong odor, so it’s not recommended to spray it directly on plants unless it is prepared first. Dyna-Gro sells pure neem oil that must be mixed with warm water and soap. The mixture is then sprayed on your house plants.
Emulsified Neem Oil: There are products that have neem oil together with other ingredients that keep it from separating. (Oil naturally separates from water—adding soap or detergent will break up the oil globules to keep it from separating.)
What People are Saying
Based on all the consumers’ reviews we’ve scanned, these are the top things they mentioned about their new stuff:
Keep neem oil in refrigerator: Neem oil will solidify at low temperatures, but it’s recommended to keep it in the refrigerator, so that it stays fresh longer. You shouldn’t heat the oil over 85 degrees Fahrenheit (30 degrees Celsius), because it may destroy the active ingredients in the oil—which have the greatest insecticide action.
Reapply after rain: Rain will tend to wash the oil from the plants and the surrounding soil, so you will have to reapply it. But you can use less oil every successive application. You’ll notice that even a small bottle of the oil will last a long time.
Against types of mildew: There is a powdery mildew that accumulates on squash and cucumber plants. Neem oil is found to be effective in controlling it.
Adjust concentration: People noticed that the oil that has been mixed will not work well against some pests, such as aphids. You can try playing with a higher concentration in such a case, until the problem is solved.
Useful Tips for Shoppers
To protect foliage: People recommend spraying the foliage of their plants towards dusk with a mixture of the oil with soap. The mixture dries overnight, and should protect the plants from insect pests. If you are using 100% pure oil, mix 1.5 teaspoons of oil in 32 oz (approx. 1 liter) of warm water, along with ½ teaspoon of liquid soap. Shake the mixture, and spray it on the plant’s leaves.
Note: Plant experts warn not to apply the spray during hot weather above 85 degrees Fahrenheit, or when exposed to direct sun. This can cause irreparable damage to the plant leaves.
Mosquito repellent: Neem oil can be used as a mosquito repellent as well. People have noticed that a mixture of 2% neem oil together with coconut oil, when applied to the skin of volunteers in malaria-infested countries, were protected from mosquito bites for up to 12 hours.
Against Bedbugs: There are special products containing up to 22% neem oil, which can be used to eliminate bedbugs from problem areas (in a bedroom, there isn’t any of the other concerns about accidentally killing beneficial insects or harming plants).
Treat wrinkled skin: Undiluted oil shouldn’t be applied to the skin—it may cause an allergic reaction. If mixed with 16 parts of jojoba oil to every part of neem oil, it is effective as a skin moisturizer.
Other skin treatments: Neem oil has a certain antiseptic effect. So people have been employing it as an acne treatment as well.
