Spider mites on orchids can be eliminated using four different methods. There are a number of methods that can be used, including prevention, isolation, spraying, and pesticides. Keeping this in mind, you can see that eliminating spider mites necessitates a multifaceted approach that includes both treatment and prevention.

In the greenhouse, dealing with pests is easier since you have more control over the environment. Spider mites, which are minuscule and difficult to detect, are the exception to the rule when it comes to getting rid of pests. As a result, whether your orchids are indoors or out, the approaches listed below are better suited.

Orchids are also infested by three different kinds of mites. Thus the moniker “spider mites,” which are more often known as two-spotted mites, are a type of spider. While flat mites and fake spider mites exhibit similar symptoms, they do not produce a web of their own.

Finally, if you detect yellowing on the leaves of your orchids, you may have a broad mite infestation.

Preventive measures are the first line of defense against spider mites. Preventative measures are still necessary even if mite infestation is obvious. According to the American Orchid Society, these pests like a warm and dry habitat.

This is where a greenhouse comes in handy, since you can keep an eye on the temperature and humidity levels inside. This is based on the fact that spider mites are more tolerant of high humidity, hence limiting humidity and wetness in greenhouses can slow their activity. Misting your plant on a regular basis can help prevent, control, and ease the removal of pests.

To keep your orchids healthy and free of spider mites, avoid overwatering and take a quick warm shower once a month. If you lower the temperature, it will also be beneficial. Ensure that orchids are kept at the correct temperature, but keep an eye out for conditions that spider mites enjoy.


The University of Florida recommends that infected orchids be isolated as soon as possible. As you continue to treat for spider mites, you’ll find it easier to keep an eye on their numbers and activities. Allow for an area of isolation, and you may later use this space to store additional orchids as they grow.

You should also check the soil around the plants that have been affected. In order to avoid recontamination by spider mites, it is best to remove the old media and repot. Before repotting, take sure to rinse the roots of the orchid plants with distilled water.


Spraying or brushing the affected plants is the most popular home method for getting rid of spider mites. To begin off, use water to wash the orchid leaves to remove any minute mites. This is a good place to look for mites, as they like to hide behind the leaves.

Use a soft sponge and water to eliminate mites that are lurking in the nooks and crannies. In addition, you should do everything you can to remove the webs and eggs. As long as the problem remains, spraying the affected orchids with water can continue for up to six weeks.

To further reduce the quantity of spider mites, you can put a soapy solution on the foliage before rinsing it. Hard-to-reach areas can be cleaned with an alcohol-and-cotton-swab combination. Instead, try misting some alcohol with some mild liquid soap.

Alcohol is sufficient for mild infestations, but be careful with powerful solutions to prevent harming orchids. Rub alcohol should be avoided on tender or thin-leaved plants. Using 1 part rubbing alcohol, 1 part Murphy’s oil soap, and 2 parts water is a good starting point.

Insecticidal soaps and horticultural oils

Insecticidal soaps and pesticides are options if the first three methods don’t work. However, it’s always a good idea to read the product directions on the label before using anything new. Insecticidal soaps and horticultural oils are safer and less resistant to pests than insecticides and pesticides, therefore use them first before using them.

Since they’re less harmful to the environment, they’ll be more effective when an infestation is just getting started. Spider mites can only be killed by direct contact, thus they must fully soak the orchids. Neem oil mixed with water and plant-safe detergent is a reasonable alternative.


Miticides can be used to control mite infestations that are difficult to control if the label instructions are followed. Determine how often and for how long you must reapply insecticide to keep the population under control. Keep in mind that not every insecticide can be used on orchids, and always transfer the plants outside to ventilate the fumes.

Your orchids might convey their fear of spider mites if they were able to speak.

There are two kinds of these sap-sucking orchid bugs can be found. This spider mite, which has two black spots on a yellow-green body, is found across North America. Tropical regions are the natural habitat of the flat mite.

Due to their minuscule size, spider mites are nearly impossible to identify before their damage has taken place. A silvery sheen on the underside of the leaves of a threatened plant indicates sap loss.

Isolate, then eradicate

So orchids near a sunny window may be more susceptible to spider mites. A humid greenhouse is a good alternative, but for most orchid owners, simply spraying down your orchids regularly works, too.

Mites that resemble spiders are called spider mites because of the way they build their webs. A tiny mist of water applied to the leaves will reveal the web and any orchid pests that may be hiding there. Destroying the web is essential because it prevents the leaves from receiving topical therapy. In order to prevent the spread of spider mites from one pot to the next, keep all web-infested plants separate from healthy ones.
