Spider mites are small, difficult-to-see insects that can infest orchids, particularly on thin-leafed ones. They prefer easy meals and are less common on thicker, more succulent orchids like Cattleya. There are three groups of spider mites infesting cultivated orchids: spider mites, flat mites, and broad mites. The two-spotted mite, or red spider mite (Tetranychidae), causes a chlorotic spot or stipple at each leaf, most often found on new growth and thin-leaf orchids.
To identify spider mites, wipe a white cloth or tissue over both sides of a leaf suspected. Spider mites can cause significant damage to the orchid, particularly on the underside of the leaves, as they kill cells on the surface layer. When spider mites are present, the top side of the plant also suffers.
Spider mites are common in houseplants and can attack orchids too. It is important to identify, isolate, and treat a spider mite infestation to ensure their safety. Spider mites are closely related to spiders and scorpions, making it crucial to recognize their damage so that they can be controlled.
In summary, spider mites are small and difficult to see, but they can cause significant damage to orchids, especially on the underside of leaves. To control spider mites in terrariums, vivariums, or orchidariums, use Phytoseiulus persimilis or the predatory gall midge, Feltiella. Spider mites prefer thin-leafed orchids due to their easy meal and preference for easy meals.

Today I am redoing my spider mite solution against spider mites that I like the most, as a step by step guide! ▽▽▽More info …
What are the spider like orchids?
Brassia caudata, also known as the Spider Orchid, is an endangered species found in Mexico, West Indies, Central and northern South America, and Florida. Its inflorescence consists of large spindly flowers with long slender yellow-green sepals and barred, blotched petals. The orchid was heavily impacted by freezes and fires in the late 1960s and is considered vulnerable throughout its range. It has not been seen in Florida since 1990 and is believed to be extirpated.
Pollination occurs when the speckled petals and sepals resemble spider legs and fool female spider-hunter wasps in the genera Pepsis and Campsomeris. The wasp stings the flower’s lip and comes into contact with the pollinarium, transferring pollen to the next Brassia flower it visits.
How to remove spider mites from an orchid?
To eradicate spider mites from an orchid, it is recommended to utilize a combination of soap and water, vegetable oil, or dish soap and rubbing alcohol. It is recommended that the aforementioned treatments be applied to the leaves of the plant in question once per week for a minimum of three weeks in order to eradicate all pests. For further information on the care of orchids, please refer to our website.
What is the rarest color of orchid?
Blue orchids are rare and beautiful, symbolizing rarity and strength. They are often dyed to maintain their striking color, while the calmer blue tones represent peace and calm. Their soothing presence creates a relaxing and harmonious environment, making them ideal for places where calmness is desired. The exotic and rare nature of blue orchids gives them a sense of elegance and luxury. Gifting blue orchids can convey a message of specialness and extraordinaryness, making them perfect for celebrating unique friendships.
Purple orchids, closely linked to power or royalty, are known as the ‘true queen’ among flowers. Their elegant appearance and deep symbolism add sophistication and meaning to any setting. They are perfect gifts for those who admire others, as they symbolize respect and appreciation. Both blue and purple orchids are perfect for expressing love, admiration, and appreciation.
How rare is the ghost orchid?
In 2023, several environmental protection groups have requested the US federal government to expedite the process of granting the Ghost Orchid protections under the Endangered Species Act. The ghost orchid, which is believed to be endangered due to poaching and habitat loss, is found in only 1, 500 plants in Florida, including the Audubon Corkscrew Swamp Sanctuary. The plant has been featured in various media, including the non-fiction book The Orchid Thief by Susan Orlean and the movie adaptation of the book, Adaptation.
The ghost orchid also inspired the fiction novel Ghost Orchid by D. K. Christi. In the Netflix series Wednesday, it is falsely stated that Dendrophylax lindenii was first discovered on The Isle of Wight in 1854 and is “carnivorous”. It seems that script writers Alfred Gough and Miles Millar confused it with another “ghost orchid”, the European Epipogium aphyllum. The painting of the plant also plays a role in the fiction book The Ghost Orchid by Jonathan Kellerman.
Various sources have provided information on the status of the ghost orchid, including its flower composition, its conservation status, and its relationship with other “ghost orchids” such as the European Epipogium aphyllum. The taxonomic exaggeration and new hypotheses for Darwin’s orchids have also contributed to the ongoing debate on the status of the ghost orchid in Florida.
In conclusion, the Ghost Orchid is a critically endangered species in Florida, with only 1, 500 plants remaining in just a few locations. The US federal government should accelerate the process of granting protections under the Endangered Species Act to protect this vital species.
Can you wash off spider mites?
Spider mites can infest houseplants, so it’s important to keep them in a cooler room away from healthy ones. Keep the soil moist but not overly saturated, and water them when the top half inch of soil is dry. Repeatedly washing plant foliage with a soft cloth or a forceful spray of lukewarm water can help reduce the spider mite population. Other control options include treating plants with insecticides containing permethrin or pyrethrin, as well as insecticidal soap and horticultural oil.
Always read the label carefully before using any pesticide, as the availability and recommended use may change from year to year. If the infestation is severe, discard the plant and place a plastic bag over it to prevent mite migration. To prevent future infestations, keep newly acquired houseplants in an isolated area for a few weeks and monitor them for pest problems before placing them with the rest of your healthy plants.
Is it OK to touch orchids?
Unsanitary handling of orchids can lead to the development of viruses, especially in unopened buds, which are the most sensitive parts of the plant. To prevent this, it is essential to thoroughly wash your hands with soap and warm water before handling the plant, and consider wearing disposable gloves for extra precaution. Additionally, sanitizing your tools before trimming spikes is crucial for stimulating reblooming, but not doing so can result in the development of a virus that could potentially kill your orchid. Always discard gloves after use if they come into contact with a sick plant.
Are spider orchids rare?
The coloured spider orchid (Caladenia colorata) is a nationally endangered plant found in a few properties in the Murraylands and Riverland region. Historically found in low rainfall zones across South Australia and Victoria, it has dull-green leaves with a reddish base, red and hairy stems, and produces 1-2 cream-green, red or purple-brown-marked flowers. The plant is currently under conservation efforts to protect its remaining specimens and support their natural propagation. The plant’s flowers bloom between August and September and sometimes emit a faint petrochemical smell.
Are spider plants related to orchids?
Spider orchids are a type of orchid in the Brassia and Caladenia genera, both of which are known for their unique and attractive flowers. Brassia species, which are native to southeastern North America, the West Indies, and parts of Central and South America, are known for their yellow, greenish yellow, or orange-yellow flowers. Caladenia, a genus largely native to Australia, consists of around 350 species of terrestrial orchids, each with a single hairy leaf and a variety of colors. These orchids are difficult to grow and require symbiotic fungi for flourishing. The central labellum, a modified petal, is often delicately fringed.
Are spider orchids poisonous?
Spider Orchids are safe for families due to their non-toxic status, similar to the benign Jewel Orchid. Parents and caregivers should be vigilant around children, keeping them elevated and out of reach to prevent nibbling and protect the delicate structure of the orchid. Education is crucial, and parents should discuss the importance of admiring plants with their children using simple language and role-playing scenarios. A well-timed distraction can be more effective than multiple reminders, ensuring a safe and enjoyable home environment for Spider Orchids.
Why do spider orchids look like spiders?
Spider orchids, known for their exotic appearance, have long stems with spidery-looking flowers that evolved to attract a female parasitic wasp. The wasp lays eggs on the spider-like flowers, covered with pollen, and moves on to the next spider, pollinating the plant. Brassia orchids, native to wet, tropical forests of Central and South America, are named after 19th-century British botanical illustrator, William Brass.
Orchid hybridizers have crossed Brassias with Miltonia and Ondontoglossums, creating fragrant hybrids with large, spidery flowers. Understanding a plant’s native habitat is crucial for successful plant growth.
What are the spider webs on my orchids?
The red spider mite is the most common mite affecting orchids, with webbing on leaves and tiny red specs moving about. To get rid of mites, purchase a pesticide specifically labeled for mites. For small infestations, wipe infested areas with a cotton ball dipped in rubbing alcohol. Repeat this procedure every week until no infestation is visible. If using a pesticide, two repeat applications at weekly intervals are necessary.
Grasshoppers, especially lubbers, can cause significant damage to orchids in a short period. They are typically 1″ to 3″ long and can vary in color from yellow to black. Control them immediately using hand, pruners, or shoe/boot.
📹 How I control spider mites in my Orchid collection – Simple!
The spider mites battle has been a long and laborious hassle for me the past years, mainly due to my way of handling things …
Thank you thank you Danni! I just discovered spider mites in my collection, and immediately used this treatment. One thing that helped: I used a spray bottle called a “flairosol” bottle, that is popular for hair and beauty applications. It has an ultra fine mist that coats very nicely. You can get them from Amazon.
Thanks a million Danni!!! Could you do a tutorial on how you mix your spray, and how you apply it? Would you spray the leaves, roots, stems, flowers and media. Should I re-pot in new media, even if I reported 2months ago? I think 2% of 1cup of water = 2ml = 40-50 drops of oil & maybe 3 drops of dish soap. Does that sound like the right proportions? Any guidance is greatly appreciated!!! Your shared experience is tremendously helpful!!!
This was BRILLIANT! I loved to hear the reasoning through which you got to this conclusion and found a solution. I’m surprised that this kind of oil could be used. I knew about horticultural oils, but they are hard to find, and expensive, sold in larger quantities, not something one would like to buy just to try and see it doesn’t work. This is very interesting! Could you maybe add instructions on your webpage, on how to measure the ingredients, and the proportion, and all, I think people would find it useful. Maybe even a article showing the preparation and the treatment being applied step by step (though part would be a repetition of what you already told in this article). Can this be left on the leaves? If sprayed on the underneath of the leaves, does it clog the pores? Does it need to be removed with water and soap, or is the soap you add in the mixture enough to break the surface tension such that it won’t clog the pores? How do you search for spider mites? I have a 20x magnifying lenses and the same USB microscope you showed in an old article. But I find it hard to find or identify things with them, though when an year ago I had spider mites on a plant, I could see them clearly with the USB microscope. But they are too tiny and hard to find.
Dear Miss, I had the same problem with my orchids last year. I used a liquid : 1ml dishwashing liquid + 3ml cooking oil + 1l water. I used this liquid once a week in 3weeks, then, 1time per 2 months (for prevention). spray every part of my orchid (including the roots). And, the problem was solved. The liquid is not hurt orchid’s roots or leaves. I hope this will help you a little bit. (I am not english so sorry if I wrote something wrong) 😀
Thank you so much for this article. I just discovered false spider mites on one of my cycnotes orchid. I had a large magnifying glass and was able to ID them. Red, of course! I have tried miticide but not sure if it’s working. In the meantime, I’m checking the other orchids daily for evidence. I love your articles. You have inspired me to grow orchids again.
@MissOrchidGirl Thank you for the good advice. I just noticed my first, very tiny, red spider like bug on an orchid leaf today. Have you done a article showing how you specifically mix the amounts, and addressed some of the questions here? Many of us would feel more comfortable trying it by perusal it being shown, please. Much appreciated.
Thank you for the advice. I am feeling very despondent at the moment with all the problems I have with my orchids and feel comforted that other people also have similar problems, including you! Most people just show their prize winning orchids with no blemishes or infections and one begins to think that you are too inexperienced to grow and look after them. I will keep trying!
I am about 50% inorganic now and not looking back. Not insect free but much better than bark. I hope your oil keeps working. In the past, I have resorted to unpotting and just dunking them all in a bucket/bath or hose pipe sprays. This can take an entire day for all my orchids. I did it for mites – mine turned out to be the non harmful kind but it was getting too much.
So happy you found a solution to this problem! Wow! I had a scale infestation last winter in my indoor garden and it was horrible, so I can really relate to your problem… cured mine with neem and coconut oil. Incidentally, neem has been used as birth control, so it does more than just smother. Happy growing! 🌱
Dani- Hi, I had a problem with Spider Mites about two years ago when I started collecting orchids my self. I found a nice formula from Brads Greenhouse, for a natural spray. It uses Alcohol as the base along with water and several drops of dish detergent. Since I have started using this I haven’t had a problem. It seems to be effective. I also try to keep the humidity high. Don’t know if this has anything to do with it or not. So, just my two sense, Thanks for all your informative articles, don’t think I’d be half the enthusiast without you! Thnx
I think I’m dealing with this now and I’m freaking out because I have about 300 or so orchids. I am so glad you posted this as I have been on the phone trying to find out about systemic insecticides that can be used in the house! It’s winter and I can’t take them outside to spray and I have kids and pets. I remembered you had posted spider mite articles and looked up a few you made! Now I’m off to the store to find some oil like you used here! Thanks!
Interestingly a Orchid shop I recently discovered had premix insecticide for sale that is made up of four ingredients being Mineral oil, Bicarbonate of Soda, Soap & Methylated Spirits (Denatured alcohol), I guess water as well. I am not sure of the ratios but I have not had any ill effects on any of my orchids thus far. After researching the use of each it looks like a good combination in theory. With the help of your article I have an idea for the oil part of the mix so I can hopefully make my own next time, thanks!
I knew my orchids didn’t have a fungus!! I have been using a copper based fungicide for 3 weeks now to no avail and did a test by rubbing and tapping some affected leaves over white paper and the microscopic black flecks started to move!!!! the worst plants affected have gone pale and the leaves are turning silvery!!!! I need to get rid of these asap!!!!! hopefully I can find the oil you got in your country here in the USA… I have been struggling for a while and now I FINALLY know what it is!!!!!!!
Hi Danni~ I thought I would like to let you know I tried baby oil and it didn’t work! DX I also increased the quantity and it only ended up burning the leaves TT_TT! So I’m going to seek out a product with petroleum or paraffin oils, which is a bit tricky to come across in Australia since I’ve noticed that beauty products here are goin paraffin free >_< Thank you though for doing all the experiments and stuff to give us spider mite haters more hope 😀
I have changed my approach to managing them instead of trying to eradicate. For a while, I have been taking my higher risk orchids (mainly miltoniopsis and dendrobium nobiles) into the bath tub and putting the shower on a high setting and really hosing the orchids down. I find this better than soap sprays because you can get wide coverage fast and the mites really can’t hold on! They also hate the wet leaves afterwards.
Hi, Danny! Thank you for discovering and sharing this method against spider mites. I treated all my orchids, and now they are free from the mites. But there is another question. How to treat the violets against these insects? They have hairy leaves and the oil mixture won’t cover them… Do you treat them as well?
That’s interesting. I did use an oil based solution, most likely it was with “horticultural oil” and it worked. I didn’t talk about it too much, because people tend to use the big guns on spider mites and I thought that the answer couldn’t be that easy and I hadn’t tried it out on many plants. But maybe we’re lucky. About a year ago I did a nail polish experiment to stop a fungal disease from spreading. I thought it was logical and gave it a go, but I wanted to wait to see if it worked. But unfortunately it didn’t work too well. But I think I’ll edit the footage anyway, because it might be interesting nevertheless. 🙂
Hi! Love your chanel. You are incredible 😊 Please help me. I have some questions about my phalaenopsis.. Ok. First- when I was soaking a pot with roots in a woter bowl I found out some white bugs runing inside a pot. Do you know what kind of bugs are they? Can they damage my orchid? Second- some of the leaves have a small holes. And leaves are not totally green. It have some redish strings. It have to be like that? Third- small orchid. One of it leaves have dark brown ends and other of the same orchid leaves have some spots on top. These spots are not cleanable. I don’t know how to describe it. Other thing- the stem. Is it kind of the desease that black area? I have some pictures. Hope you’ll recognise things which I meant. Sorry for my english, hope you’ll understand 😅 and I’ll wait your answers. Thnx 😊
Hello, some days ago I got an orchid in a nursery and it has spider mites. As I didn’t knew I bought it and it infested some of my other orchids. Can you please make a article on the things we should look before selecting an orchid to take it home? . Now I have learn that I have to look the back of the leaves but I don’t know if there are other aspects to take into account for not having this surprises again
hi Dani, I just watched your spidermite saga from 2015 till now. just to learn about pest and other nasty stuff BEFORE my plants get any so I know what to look for and what best way to procede. so thanks for al your experiments. I just have 10 orcids so I don’t want to sacrifice 1 to science 🙈. ps what phalaenopsis is that pink striped mini that’s in the end and beginni g of your vid? I just bought 2 mini phals. at aldi’s last Thursday. and one had exactly the same flowers the other has light green with a bit of purple. and that one is not doing good in the spagnum media it was to wet and to packed so she was suffocating and had a worm crawling out of the spagnum. altho she is in bloom I unpotted her slrayed wirh hydogen peroxide 3% and put her in handpicked tiny leca beads. but I relay would like the know her name. so I can look up the specific needs of that tiny phal.
Did you try a bleach solution (1:10/bleach:water) at some point? I use that with newly purchased aquarium plants. Before they enter my aquarium they get a bleach dip. Works wonders for all the worms and snails and they’r eggs as well as algae and any bacteria! I learned my lesson the hard way, and since then I use bleach. On the other hand the orchids seem to have sensitive leaves… not sure about that…
So based on this article would you suggest Nivea or baby oil as insecticide mixture. Did it work ? I don’t think mine are spider mites though. Not entirely sure what they are. I asked my county horticulture center sending pictures and articles to their email and they thought possible mealy bug infestation but they aren’t fuzzy looking and white how most mealy I see almost resembles bugs springtails or thrips article more I think. They seemed gone for weeks and it was like overnight all my planters were crawling badly with them again. Not sure if it was eggs all hatching at same time or what ..
Hi Danny, I just found spider mites on 5 of my orchids and it has been at least 4 months since I had to treat a good number of them,. but it went away after using the same solution you came up with. It TOTALLY works, however, do you recommend that I unpot my orchids everytime I find spider mites in them? It just seems too costly for the orchids that I have in organic medium to have to basically get rid of the old medium and add fresh medium all over again. The good thing is most of my orchids are in leca so its not too big of an issue.
I went to several local pharmacies (Walgreens, CVS) and Walmart yesterday. None have any oil with paraffin. Nearly all are mineral oil based and paraben free. None, including all baby oil, had paraffin listed in their ingredients. The few that were not mineral oil based (sunflower, sesame, rosemary etc) did not contain paraffin either. Any suggestions of what else to use if you can not find any oil with paraffin?
What would you say is the best way to test an orchid for spider mites? I purchased a dendrobium yesterday which has some fine webbing in a couple of areas. I have found two tiny spiders (actual spiders!) on the orchid so I’m hoping they are the only cause of the webbing. I have wiped the underside of some of the leaves with a tissue and nothing comes off, except a small amount of some powdery black stuff which is here and there on the plant, and wipes of completely with no damage underneath. I have so far kept this new orchid separate from my old ones and I’ve done nothing to it but will be repotting on the weekend. What do you recommend?
would you recommend the oily spray solution for prevention against red spider mites? i had them a couple of years ago, and i got the fleck virus, so trashed my collection of 40 phal. violacea. but i thought i would give orchids another go, but i am scared to be to late to react if i get an infestation, so i am already thinking of doing this as prevention of infestation… what are your thoughts?
Hi Danny, I was given this beautiful phal a week ago and I noticed that 2 of the leaves have spots that I’m not sure what causes it. The phal is still in quarantine and if it’s caused by mites, I would definitely try your method. Here are the pictures of the leaves and thanks for making such an informative (and entertaining) article. Cheers! dropbox.com/sh/d8qmax6e6oimwjp/AACvTnlItZgKY99AIk5SjnQPa?dl=0
At 12 minutes towards the end of the article you said “the more you play with some soapy water, trust me the worst it will get”…….does this mean that soapy water will not work against spider mites? Are you required to use oil in the mixture for properly fighting spider mites mechanically? I am afraid of using oil without an exact recipe of measurements.
