Mites 3

Spider mites are a common pest for plants, causing damage and potentially killing them. They are known to infest a wide variety of plant species, making them a significant problem for gardeners and plant owners. One natural remedy that has been suggested for controlling spider mites is cinnamon. But does cinnamon kill spider mites? Let’s delve into the details.


Yes, cinnamon can kill spider mites. It acts as a natural antimicrobial agent that repels spider mites and kills them upon contact. Additionally, it can interrupt the breeding cycle of these pests, helping to control their population. However, it should be used responsibly and in conjunction with other plant care practices for effective control of spider mite infestations.

What Are Spider Mites?

Spider mites are members of the Tetranychidae family, which includes about 1,200 species. These tiny creatures, less than 1 mm in size, are related to spiders, ticks, and scorpions. They are known for their destructive feeding habits, where they puncture plant cells and consume the contents. This results in tiny yellow or white speckles on the leaves, leading to a yellow or bronzed appearance. If left unchecked, spider mites can cause significant damage, including premature foliage drop and plant death.

The Power of Cinnamon Against Spider Mites

Cinnamon has been found to be effective in controlling spider mites. This common kitchen ingredient is naturally antimicrobial, repelling spider mites and killing them upon contact. Additionally, it interrupts their breeding cycle, which is crucial in controlling their population.

Several studies support the use of cinnamon against spider mites. In one study, cinnamon oil showed 85.8-100% mortality against twospotted spider mite adults at certain concentrations. Another found that cinnamon oil caused 50% mortality to T. urticae after 2 days of exposure.

Using Cinnamon to Control Spider Mites

There are several ways you can use cinnamon to control spider mite infestations:

  1. Cinnamon powder: Sprinkle cinnamon powder around the base of the affected plants and on the leaves’ surface.
  2. Cinnamon spray solution: Prepare a cinnamon spray solution by boiling water with a few cinnamon sticks or powdered cinnamon. Once cooled, strain the solution and spray it on the affected plants.
  3. Cinnamite: Apply this non-toxic pesticide derived from cinnamon oil according to the manufacturer’s instructions.

Remember, maintaining proper plant care and proper humidity levels can also prevent spider mite infestations.

Cinnamon’s Environmental Impact

While cinnamon can be helpful in controlling spider mites, it’s essential to consider its potential environmental impact. Cinnamon production has been associated with deforestation due to the need to cut down whole trees. However, if produced responsibly, there’s no known significant damage to air, water, land, soil, or forests.


Cinnamon can be an effective, natural method for controlling spider mites. Whether you want to prevent an infestation or deal with an existing one, this common kitchen ingredient could be your solution. However, it’s crucial to use it responsibly and in conjunction with other plant care practices to prevent spider mite infestations effectively.
