7 Tips for Preventing Orchid Pests and Disease

  1. Buy healthy plants.

      Before making a purchase inspect leaves for reddish-brown to black spots. Do not buy plants with spotted leaves (like those in the above photo). 

  2. Provide air circulation.

      Orchids love humidity, and so do bacteria.  To prevent diseases that thrive in a humid environment, turn on a fan. Air circulation will do wonders in preventing bacterial growth. 

  3. Avoid overwatering.

      Besides killing your orchid’s roots, standing water is like sending an invitation to unwanted bacteria to come to live in your orchids. 

  4. Keep it clean.

    Always sanitize pruning shears and other tools. Pass tools through a flame, wipe down with rubbing alcohol or dip in a bleach solution (2 parts bleach to 10 parts water). A well-maintained growing area includes picking up dropped flowers, weeding, dead leaves, dried sheaths, and other debris. Trim off old flower spikes, dead leaves, and pseudobulbs. Keep unused pots and mounts put away and floors swept clean of potting media. Empty trash regularly. 

  5. Frequent health checks.

    Take time to regularly inspect under leaves, and around small crevices. Some insects are large and easy to see. Other pests are very small and are more easily spotted with the use of a magnifying glass. If you can catch pests and disease in the early stages, they are much easier to control and gentler measures can be used to control the problem. A good time for health checks is when water, potting, and at the beginning of each season, making is much easier to treat orchid pests and disease should they occur.

  6. Isolation. 

    As an extra precaution isolate new plants for a week or two, just to be sure that it didn’t bring any hitchhikers, in the form of disease, along. This advice has saved my orchids. Sometimes we may overlook bacterial spots that somehow become glaringly obvious once at home.

  7. Proper care.

    Healthy plants will more easily fight off pests and disease, while weak plants are much more susceptible to succumbing to pests and infection.






Root, rhizome, pseudobulb
rot and leaf spots can all indicate fungus.

To treat fungal and
bacterial infections, use sterilized pruning shears to cut away affected area. Apply cinnamon paste to lesion. For fungal infections, apply beneficial fungi or, a copper-based
insecticidal soap.
For bacterial infections, apply beneficial bacteria,
or refined horticultural oil or insecticidal soap.


A spotted or sunken area where water was left sitting; a foul smell.

Treat bacterial infections as you would fungal infections


To prevent fungal and bacterial infections, remember three things:

1. Use a fan.
2. Always sterilize tools.
3. Try not to overwater, which leads to rot. Rot leads to infection.


Viruses are difficult to diagnose. Still, viruses can be
identified by a color break in blooms. A viruses tend to be
in not on plant tissue. Watch for streaking.

To accurately identify a virus you must take a sample and send it to a commercial lab such as agdia.


Here’s how viruses are spread: the sap from an infected orchid comes in
contact with a healthy orchid.

To prevent tool transmission
make sanitation a top priority. To prevent insect
transmission, keep insects under control.


Identify sunburn by leaf collapse. As time goes on the leaf will continue to deteriorate. A sunburned leaf will feel squishy.

Remove the burned leaf. Apply a cinnamon paste to the orchid where the leaf was removed.


Keep the orchid away from direct sunlight and do not leave an orchid in your car.

– Water
– Re-pot
– Sterilize tools with a flame or rubbing alcohol

Identifying Bacterial and Fungal Rot

As you will see, bacterial and fungal infections are identifiable by rot. Look for areas that are black or brown, mushy, seeping, and stinky.

Common Bacterial Infections

Bacterial Brown Rot begins with a small, brown watery blister on a leaf that quickly spreads until the entire leaf is brown and dead. If the infection reaches the crown or rhizome, the orchid will die.

Brown Rot is caused by the bacterium, Erwinia, which begins as a small brown spot on the leaf, but quickly spreads. Identify brown rot by its foul smell. If the infection reaches the rhizome, the orchid will die. 

Black Rot is caused by fungi, Pythium ultimum, and Phytophthora cactorum, often has a watery appearance, and can quickly kill a plant if not treated before it reaches the rhizome or roots. 

Root rot is caused by the fungus, Rhizoctonia, and attack roots potted in decomposed or poorly draining media. 

As root rot affects roots down in the potting medium it is difficult to see the rotten roots. Look for symptoms like failure to thrive – small new growths, shriveled leaves, and pseudobulbs. Take action immediately to prevent the fungus from killing your orchid. 

Treat by re-potting the infected orchid and removing damaged roots. Use fresh potting media. Follow up with fungicide according to product instructions. 

Common Fungi Infections

Leaf-Spotting Fungi is common and is not usually lethal. In fact, many orchid growers call it par for the course and don’t do anything except to improve general care practices like watering in the morning, providing good air movement, keeping water off the leaves and crown. This type of leaf spotting is identifiable because it is slow-growing and will not quickly destroy the orchid. If you do decide to treat leaf-spotting fungi, use a fungicide per product instructions.

Petal Blight caused by the fungus Botrytis cinerea causes black spotting on the orchid’s flowers. Good air movement will prevent petal blight. Keep water off flowers. Remove infected flowers.

Treating Bacterial and Fungal Rot

Treatment for bacterial and fungal infections includes: removing rotted plant tissue, applying disinfectant, and improving culture practices.

Removing Infected Areas

As a precaution remove a small portion of healthy tissue, using care not to touch the infected area with shears. After making the cut, examine the tissue to make sure no infection remains. Look for any brown discoloration.

Applying Disinfectant-Fungicide

Let the cut dry, then dust with ground cinnamon. For a longer-lasting seal, mix cinnamon powder with Elmer’s glue and apply it to the wound. 

Carefully clean the growing area with Physan, a disinfectant, fungicide. As an extra precaution treat the orchid with a Physan solution of 1 tablespoon Physan to 1 gallon of water. 

Always sterilize shears before and after use. If treating more than one orchid, sanitized before moving on to the next orchid. To sterilize, pass tools through a flame, wipe down with rubbing alcohol, or dip in a bleach solution (2 parts bleach to 10 parts water).

Improving Culture Practices

Next, here are a few ways you can help prevent future fungal and bacterial outbreaks:

  • Provide constant, yet gentle air movement. Point a fan away from your orchids, and turn the fan to the lowest setting.
  • Water in the morning. This way any water accumulation on the leaves will dry before nightfall.
  • Use care to keep water off the leaves and flowers. 
  • Keep paper towels on hand to absorb water that accumulates in the crown of the plant. Pay particular attention to phalaenopsis and paphiopedilum orchids.

Identifying Viruses

This is the bad news: Viruses are microscopic and can be difficult to diagnose and almost impossible to cure. Remember, viruses are most often identified by color streaking. Keep in mind that virus symptoms copy-cat symptoms of pests, nutritional deficiencies, pest damage, fungi and heat, and cold damage. A virus may even be present without manifesting any symptoms. 

At any rate, here are symptoms of viruses:

  • Color break or streaking in flowers and foliage
  • Loss of vigor
  • Yellow-white lesions
  • Dead leaf tissue – may look like frost damage
  • Leaves with stripes and rings
  • Irregular twisting, pitting, and curling of leaves

Treating Viruses

The best course is to throw out such plants. If you don’t want to throw out your orchid, keep it away from your other plants. Use caution and keep all tools (watering cans, razor blades, etc.) away from the infected orchid. If you do use a razor blade, be sure to throw it out after use.

TIP: To accurately identify a virus you must take a sample and send it to a commercial lab such as agdia

Improving Culture Practices

Since viruses are impossible to positively identify without a lab test and impossible to treat, best culture practices are a must. The following are a few things you can do to keep from introducing and spreading viruses into your orchid collection:

  • Ask the seller if they regularly test for viruses.
  • Sanitize all tools, including shears, pots, and surfaces. Change disposable gloves when potting multiple orchids.

Preventing Pests

As always, an ounce of prevention is worth a pound of cure: Check new plants for signs of pests before purchasing. Keep new plants away from other plants until you are sure the plant is healthy and pest free. Bugs are a huge nuisance, but you can take action against them. As soon as you notice them, begin treatment right away. 

Vigilant surveillance is vital to preventing an infestation of pests. 

Identifying and Treating Pests

Just the word scale gives me a shiver of distaste! These little beasts can easily spread throughout an entire collection if you’re not careful. The first step is always prevention. Then you’ll need to know how to identify pests and know how to treat pests to get rid of them. If you notice any sort of pest, immediately remove the orchid away from the rest of your orchid collection.


Look for aphids on the most tender parts of your orchid, especially news growths. Aphids are soft-bodied green, yellow, or black insects. As a sucking insect, their greatest threat is that they may spread disease, particularly viruses between plants. 

To treat aphids take your orchid outside and spray off the aphids with a strong stream of water. Watch closely as it only takes one aphid to start a colony. Check your orchid regularly to be sure the aphids are not making a reappearance. 


If you notice a cottony, web-like substance around the base of the plant on pseudobulbs, rhizomes,  or on the underside of leaves you may have mealybugs. Another tip-off is the presence of ants. Mealybugs excrete honeydew that attracts ants. 

Here’s how to treat mealybugs and scale in 3 steps:

  1. First, isolate these orchids from the rest of your collection.
  2. Second, spray the plant with horticulture oil. This is most effective when bugs are in the nymph phase.
  3. Third, with an old toothbrush and 70% rubbing alcohol, and a pair of surgical gloves scrub every nook and cranny of your orchid. This may seem overwhelming when you first look at your orchid, especially if your orchid is large, with lots of leaves and pseudobulbs, but you can do it. Once you get started, it’s not so bad.

Additional Measures to Treat Mealybugs and Scale

I recommend pouring a small amount of rubbing alcohol into a dish so that you can easily dip the toothbrush into the bowl without contaminating the rest of the alcohol.

Keep the toothbrush and alcohol on hand so that you can repeat the process every 10 days, or sooner if you see signs of the bugs. After the scale has been treated the hard shells will dry up and easily flake off, though a scar will remain.


Scale, particularly armored or Boisduval is considered the worst of orchid pests. Unlike mealy bugs, you can’t simply use your fingers to brush the scale away. The scale has a thick detached shell that is practically cemented to the orchid. Look on leaves, and all around the base of the plant, for signs of this pest. These insects can be difficult to get rid of because they hide in every imaginable nook and cranny. Repeated treatment is recommended.

Identifying scale: Hard light, brown bumps that you can not scrape away indicate Boisduval scale.

treat orchid pests and disease

Treat scale the same way you would mealybugs.

Snails and slugs

Nighttime is the best time to catch snails and slugs in action. A slime trail is an instant giveaway that snails and slugs are present. Flowers, buds, and other new growth are most vulnerable to snails and slugs.

To treat snails and slugs use Sluggo, a reportedly safe product. Just sprinkle it around your orchids. The snails and slugs will ingest the Sluggo and die. 

Spider Mites

As not all spider mites spin webs, the best indicator of these pests are tiny stippling marks on your orchids’ leaves. Spider mites are very tiny and are not easily seen. If you need to, use a magnifying glass to look for these pests.

To treat spider mites, isolate infected orchids. Spray the plant with horticulture oil. This is most effective when the bugs are in the nymph phase. After treatment, keep a close eye on your orchids to be sure the mites have been eradicated. 


If you notice dry edges on the flowers, or flowers that have difficulty opening properly along with root damage, your orchids may have thrips. 

Thrips are truly beastly as they are hard to control. The most effective way to treat them is with repeated applications of insecticide. If you have repeated thrips infestations, regularly flush flowers and leaves with water. 

What to Do If You Think You May Have Pests Feasting On Your Orchid’s Roots

If you suspect that pests are down in the orchid’s roots and potting media you can safely pour hydrogen peroxide in the potting mix. As this will dry out the roots, be sure to water thoroughly afterward.

Now you know how to treat orchid pests and disease. I have confidence that you’ll be able to with the tools we’ve talked about you’ll be able to successfully eradicate these common pests and diseases.

Helpful Critters

There are many helpful friends that feast on pests, such as lizards, toads, and frogs. In addition, don’t overlook the option to purchase predatory mites, midges, and parasitic nematodes that can be extremely helpful in controlling unwanted pests.

Prevent Identify and Treat Sunburn

Along with learning how to treat orchid pests and disease, it is equally important to know how to prevent, identify, and treat sunburn. Otherwise, you may think your orchid has a disease when the leaf damage should be properly attributed to sunburn.

How to Prevent Sunburn

Use care not to expose the orchid to the possibility of sunburn. If you suspect sunburn, move your orchid further away from the window or light. Never leave your orchid in your car.

How to Identify Sunburn

Sunburned orchid leaves result in destroying the leaf tissue. At first, the leaf will just feel squishy. Over time, the least will continue to deteriorate and the leaf will turn from green to brown, and, eventually, black.

In this photo, the leaf has been sunburned and the leaf tissue has been destroyed.

How to Treat Sunburn

The best course of action is to remove the sunburned leaf with sterilized shears or a single edge razor blade. Apply a cinnamon paste to the lesion. 

Caring for Your Sick Orchid

If you have an orchid that has been weakened by pests or disease it will need some tender loving care. 

Begin restoring your orchid to good health by first removing the flower spikes. I know this may be painful, but flowering expends a lot of energy that will be better spent on recovery. 

Next, check out the root system. If it is in good shape – that’s excellent news. Otherwise, remove dead roots with sterilized shears. If fungal problems have plagued your orchids, dust the roots with ground cinnamon. 

RePot to If Root System Is Damaged

Repot your orchid with a fresh potting mix such as sphagnum moss. This is a good potting choice for rehabilitating orchids with extensive root loss. Sphagnum moss is highly absorbent and can be kept damp. Additionally, sphagnum moss, when fresh, has some natural antibacterial and antifungal properties. If re-potting with sphagnum moss, be sure that the moss is wrapped loosely, yet securely around the roots.  

The next step is to move your orchid to a more shaded location and increase humidity. An easy way to increase humidity is to make a mini-greenhouse by placing a large, clear, plastic bag over the top of the orchid. 

Reduce Water – Increase Humidity – Stop Fertilizing

While in recovery, reduce water to the roots, yet increase humidity, and wait to fertilize until the orchid has initiated new growth – particularly roots. Continue to be on the lookout for a resurgence of pests or disease. 

Prevent, Identify and, Treat Orchid Pests and Disease for Healthier Plants

These three keys: prevent and identify, treat orchid pests and disease all work together to help you grow healthier orchids. When you do notice a problem, act quickly. And above all, good clean orchid culture is the best thing you can do to prevent problems before they occur. Don’t let the inconvenience of sanitizing your orchid’s grow space and tools keep you from growing robust orchids.

    How long do you leave the cinnamon on the leaves?

    1. Anna says:

      H P,
      I don’t have an exact timetable. After a few days wipe the cinnamon off, if you still see black spots, reapply as necessary. Cinnamon really is an effective and safe fungicide.

  12. Marj says:

    Thank you for your tips! Im a newbie when it comes to orchids. My orchid just finished blooming ang is now growing new shoots. However i saw a black spot at one of the old leaves. How often do i apply it? Is daily apply application safe? Thanks,

    1. Anna says:

      After you have applied the hydrogen peroxide or cinnamon, wait to see if the brown spot is still soft and watery. You could simply remove the leaf, cutting about a centimeter past the damaged tissue with sterilized scissors. Apply cinnamon to leaf edge where the cut was made.

      A word about prevention: Your orchid’s best defense against bacterial brown spotting is good air movement. A small fan, set to the lowest setting and pointed away from the orchid will do wonders in preveting bacterial and fungal growth.

  19. Marie says:

    Hello Anna,
    I need help… orchid that I purchased around the holiday season and has been in bloom all this time is suddenly in distress. and, yes, it is still in bloom – however,
    earlier this week, one of the large leaves fell off – it’s just sitting on the table. didn’t even get moved/touched. and it was slightly discolored – like the older leaves do when they are turning color. just today, now, about 5 days later, this plant is still in the same place getting the light it needs, etc., and I noticed that the 2nd leaf is laying on the table. uh, oh – I decide to “really” look at it.

    I noticed when I took the plastic pot out of the decorative one that it’s full of the moss and the roots are looking squashed and like they are tired. I poked my little finger up through the bottom hole and it is damp. I have watched lots of u-tubes on the care, the potting, what to look for, as well as following along all your very informative “tips” to know that this plant is in distress. so, I carefully remove it from the plastic liner and nothing seems to want to move. I got a large plastic container (I keep the large plastic covers that one gets when buying a cake in the grocery store as I have found them to be very helpful when working with plants, etc. and then I don’t destroy any of the better food storage containers) – anyway – I took it to the sink and with just tepid water, I slowly lowered the plant into the container to sit for a few minutes. I then drained the water and started to very carefully remove all of the moss. No wonder the plant was crying out for help – it was packed in there solid! That whole plastic container was filled almost to the top with the moss. I noticed that some of the root system came with the moss – I guess they were truly dead. However, for the most part, the plant has lots of roots and to me, they do look salvageable. I got all the material off the roots and rinsed well under the tepid water and it is now resting.

    I am hoping I am following good protocol with this plant. I have a new medium – some moss but mostly bark that I will now repot it into.

    I guess I’m looking for some direction here from you to know that I’m doing the right thing. the other thing is – it is still in full bloom and I surely hate to cut them off – but if it’s advisable, then that is what I will do.

    I have attached some pictures so you will see just what I’m talking about. Any help you can provide would be greatly appreciated.



    1. Anna says:

      You are doing the right thing by re-potting. Be aware that the orchid will have to recover from re-potting and may lose its flowers. But, maybe not, so there is no need to cut off the flower spike unless the flowers begin to fade.
      Good job getting to the root of the problem 😉

  20. Renee Andres says:

    I have abouut 6 orchids and 3 of them are infected with this weird red mold or fungus in the soil and I can’t find anything on the internet telling me what it is or how to treat it. Please help me!

    1. Anna says:

      Apply a horticulture oil to treat the fungal or bacterial infection. Reapply weekly. You could start with one orchid and see how it responds to the treatment before treating all three orchids. Also, keep the infected orchids away from the healthy orchids and sanitize your tools.

      Your orchid just needs a few care tweaks and it should bloom. The two things it likely needs is more light and possibly a change in temperature. Check out these two posts and apply what you learn. I’m confident you’ll be able to get your orchid to flower.

    I purchased an orchid online and received it about a week ago. The post office was supposed to hold it for pick up since I am in Arizona and it is very hot right now. The orchid was delivered and left at the front door in the sun in it’s shipping box. It seemed to be okay and was packed well but was very warm. I put it on my kitchen counter to cool down and it seemed okay. Imagine my shock when I looked at it a couple of days later and it is turning black. Is this heat damage? I have separated it from my other orchids.

      I am sure it was heat damage. I’m so sorry!

    I repotted a phalaenopsis orchid I’d had for six years according to your instructions. Only two roots were green; the others were partly black with brownish fleshy sections. I removed all of them. The orchid is growing a new leaf, which is great, and several new roots, but all the roots are growing from above the medium and above all the existing aerial roots! What do I do?

    1. Anna says:

      Since you just barely potted your orchid, and it does sound like it is doing well, I recommend waiting until it completes a bloom cycle and then re-pot it again, potting up the new roots.

    There is a shiny, glimmery, wet-looking area on a couple of leaves on one of my orchids (Phalaenopsis) that doesn’t evaporate or go away. A larger blooming one has what looks like tiny water drops on the spike. The 2 orchids are next to each other. Do I worry?

    1. Anna says:

      A wet looking spot dark spot sounds like bacterial rot. The best course of action is to remove the diseased portion and increase air movement. If there is a lot of rot, use a fungicide. Use care as bacterial rot is contagious.
