Does Neem Oil Work On Spider Mites? (Guide)

There is nothing more frustrating to gardeners than dealing with pests. Even if you find a pest control method that doesn’t expose your plant to harsh chemicals, it can take weeks to remove the ravenous little creatures for good.

One of the worst contenders in the nuisance department is the spider mite. These insects look like tiny little spiders and leave behind delicate webs that blanket the leaves and stems.

More profound damage caused by these pests appears in the form of yellow or brown spots that pepper the plant leaves.

Letting spider mites have free reign over your plant opens the species up to severe damage over time. It’s best to treat the shrub or flower as soon as you notice a problem, which means employing a fantastic mode of attack.

A highly effective pesticide with natural ingredients is neem oil. Using this means you don’t have to worry about dangerous substances in your yard and ensures quick results.

Does neem oil work on spider mites?

Neem oil is magnificent pest control that works on a variety of garden insects, including spider mites. Its effectiveness comes from the combination of ingredients in a neem insecticide spray, which is generally water, soap, and the oil itself.

The water dilutes the neem oil making the mixture safer for direct use on the plant, while the soap breaks the surface tension and lets the formula do its job.

Together, they cover the spider mites and trap them beneath a coating of neem oil. This strategy, in turn, smothers the creatures already on the plant and kills them.

Later on, simply munching on the leaves and stem transmits the neem oil into the insect’s system.

Not only does it eventually kill the bug, but it also disrupts part of their biology, hindering their ability to make eggs.

All of these things combined are what make neem oil such an incredible strategy.

How often to apply neem oil spider mites?

When treating your plant for pest control, apply the neem oil once every seven days to eliminate spider mites. Doing this gives the ingredients plenty of time to work on the pests without overwhelming your plant with excess doses.

After the treatment plan finishes, and you no longer see any evidence of spider mites, you have the option of applying the same formula once every 14 days as a preventative measure.

How long does neem oil take to kill mites?

There are varying degrees of results after spraying your plants, though most gardeners see changes within a couple of days.

You may even notice a difference immediately since the blast of liquid is enough to knock some of the mites right off the plant.

Because neem oil suffocates insects, it may take a day or so before you see any significant drops in the pest population.

Neem oil also works by limiting the insects’ ability to reproduce, which means you’ll notice another dip approximately 4-5 days later.

Since the bugs cannot make new eggs, and any eggs left on the plant won’t hatch, this limits the numbers in any new infestations.

How do you use neem oil on plants for spider mites?

There are two different ways to apply neem oil on your plant, either with a cloth or a spray bottle. Both require creating the mixture first, then add it directly to the plant leaves.

A microfiber cloth works best on lighter infestations and when you don’t want to do an all-over coating of plants in the area.

Dampen the towel, and then gently wipe it across the affected areas. For greater convenience and tackling larger garden areas at once, a spray bottle is definitely more efficient.

Reapply the formula every seven days, usually for about four weeks, until you see results.

What are other benefits of neem oil on plants?

In addition to being a fabulous pesticide, neem oil is safe to use around pets and children. This benefit is one reason many gardeners choose the ingredient from the start, especially in high-traffic areas of your garden.

It has a low impact on the environment and is non-toxic to humans, pets, and most animals.

It doesn’t stop with just spider mites, either. It gets rid of most insects, including pests that affect humans more than they do the plants, such as mosquitoes.

The pesticide is also safe to spray around beneficial insects like ladybugs, butterflies, and bees since they don’t eat the leaves or plant and actually promotes the activity of other helpful creatures, like earthworms.

Another incredible advantage of this ingredient is that it makes a fantastic fungicide, as well as a foliar spray during dormant periods.

Can you leave neem oil on overnight?

Yes. It’s perfectly safe to leave neem oil on your plants overnight. There’s no need to rinse the plant off after treating it unless you are particularly concerned it will harm the plant. All plants are different, and some may be more susceptible to problems than others.

If you are worried about how your plant handles neem oil, test it out first.

The best way to do this is by spraying a small part of the plant. Check it after a day or two and notate any changes in the color or texture of the plant.

To be extra sure, you may even want to give it a week before spraying the entire plant. If there are no effects on the specimen itself, then go ahead and treat the entire plant and begin your pest control regimen.

What other home remedy kills spider mites?

There are plenty of natural remedies you can make at home without disrupting the balance in your garden.

If spraying them with a quick jolt of water doesn’t work, try a homemade mix with vinegar and baking soda or introducing natural predators to the environment.

DIY Spider Mite Spray with Vinegar

It’s particularly critical to use this spray on established plants only and to use sparingly, since vinegar often acts as a weed killer, as well.

Typically, for the vinegar to kill your shrubs or flowers, it needs to be in higher concentrations, so diluting it helps prevent damage while still eliminating pests.

Vinegar Repellent Recipe

  • 1/8 cup of apple cider vinegar
  • 1 cup of water
  • ½ tsp of baking soda
  • 3 drops of dish soap
  • Spray bottle

Substituting the apple cider vinegar for the white variety also works. No matter which you use, make sure to blend the ingredients thoroughly before spraying.

Add Natural Predators

Another great way to incorporate organic aids in the garden is by adding natural predators.

Ladybugs may just be the single greatest pest fighters out there, killing spider mites, whiteflies, aphids, and more.

Ladybugs eat about nine spider mites per hour, so you don’t have to get too many to get the job done. Find these helpful insects at your local home and garden store.

Final thoughts

No matter which method you choose, it’s crucial to use responsible amounts of pesticides when treating your plants.

Implementing a natural strategy is always ideal since chemicals that don’t damage the plants still may create problems in the soil structure and affect the surrounding ecosystem. Still, there is always such a thing as too much of a good thing.

So be sure to check that you are using the right amount of product for the size of the area being treated.
