Neem oil and spider mites

Spider mites are an arachnid which can attack both indoor and outdoor plants. They can often be most destructive in greenhouses. They are related to spiders, ticks, and scorpions, and are often reddish brown or pale. They are also very small, measuring about 1/50 of an inch long. They live in colonies, mostly on the underside of leaves, and feed themselves by sucking plant fluids from pierced leaf tissue. As they feed, the leaves turn yellow and can sometimes dry up and drop off. They appear mostly in hot, dry conditions.

A neem oil spray should be applied to plants affected with spider mites at least once per week. You should thoroughly wet the plants first, before applying the spray. You may need to reapply for several weeks before you see an improvement. Alternatively, you can also use a neem oil soil drench to help with controlling the population of spider mites.

For other types of mite, neem oil is an effective organic plant protector, and so it can be used to kill mites in your garden and in your home. Again, the best way to do this is with a neem oil spray. Apply it to the affected areas. The best time to do so is the evening, when the temperature is cooler.
