Signs of Insects on Azaleas
If you don’t know how to identify insects or plant pests, you should at least know what signs or symptoms to look for to determine if you have a pest problem.
Don’t worry, I’ll help you identify the main azalea pests in the next section.
That being said, many insects can go unnoticed due to their size or because they like to hang out in less visible places, so signs or symptoms are the first thing you notice.
Please note that while some of the following signs may mean you have a different problem, they are often signs of errors and are worth investigating.
So, some signs of pest infestation symptoms on your azaleas could be as follows.
- Your azalea leaves are falling
- Your azalea leaves are curling up
- The leaves have turned white or pale.
- yellow leaves
- Brown tips on the leaves.
- Holes in the leaves
- sticky sheets
- slow or retarded growth
- the leaves fall
- Silky bands (indicates spider mite)
- Small bumps on leaves or stems (usually indicates scales)
If your azalea is displaying some of these symptoms, but you discover that it doesn’t actually have any pests, you should read the articles linked above to find the source of the specific problem.
But since you’re here, chances are you have some bugs on your Azalea.
We will now help you identify them before deleting them.
Types of Bugs on Azaleas
Below are a few types of insects or pests your azalea may be facing right now or may appear in the future.
Azalea lace thumbtack
Azalea lace bugs are usually about 1/10th inch tall and dark in color with wings.
Unfortunately, azalea bugs tend to crawl and feed from the undersides of leaves, so you may not notice them unless you regularly check both sides of the leaves.
As they feed, you may notice the leaves begin to have white or yellow spots or the leaves wilt over time.
While this is definitely leaf damage, luckily it doesn’t have a major impact on the overall health of your azalea.
red spider
Mites are another common pest of azaleas and are very small (1/50th of an inch), so they can be quite difficult to spot unless they are forming in large numbers.
They can vary in color like yellow, red, green or brown.
The telltale sign of mites is the silky material they leave behind, which looks like cobwebs, only smaller.
These tiny pests also feed on the leaves of your azalea, causing nutrient loss by feeding on the leaf sap and causing small white or yellow spots or spots on the tops of the leaves.
Although these pests are very small, they can cause significant damage to plants and, if left untreated, can kill them.
Balance
Mealybugs or simply scales vary in size (1/8 to 1/2 inch) and usually appear dark brown or black in color.
These are usually found on the leaves and especially the stems of plants, which can be confused with small bumps that may appear to belong to the plant.
Time and time again, I’ve seen posts from people asking what these stem bits are, not realizing that they touch on different bugs.
This drives me crazy personally, eww.
Scales also feed on plant sap and are a major cause of leaf drop, yellowing of leaves and other problems related to nutrient loss.
They can also kill plants if they form in large numbers and are left untreated.
white flies
Whiteflies are another type of insect your azalea may encounter and these insects are usually between (1/16-1/10 inch) in size and have a yellow upper body with white wings.
Hence the name whitefly.
These insects are usually found on the undersides of leaves and not only drain nutrients from azaleas, but can also kill the plant if left untreated or heavily infested.
Great another pest that hides under the leaves, isn’t that annoying?
Fortunately, these bugs specifically have one major weakness.
Pro Tip: Whiteflies are attracted to the color yellow, so you can place yellow traps nearby to watch for whiteflies or to keep them away from your azalea to prevent further damage.
aphids
Aphids vary in size (1/16 to 1/8 inch) and can be different colors, such as red, green, brown, black, or other colors.
They are also another troublesome pest that feeds on the sap of azalea leaves, causing discoloration, dropping and stunting.
In addition, after feeding, aphids leave behind a honey-like substance that eventually turns into sooty mold.
Fortunately, if there are not many aphids, the damage is usually quite minor and mostly cosmetic.
It’s when they gather in large numbers that you really have to worry.
Azalea leaf miner
Azalea leaf miners are a larva formed from adult moths that specifically target azaleas rather than other plants.
They first appeared in Japan, but now wherever azaleas grow they can be affected by azalea leaf miners.
The telltale sign of leaf miners is the white or brown spores visible on the surface of the leaves, as the pests burrow between the leaves and treat them like their own personal tunnel.
Luckily, azalea leaf miners don’t actually cause plant health problems, they just cause significant leaf damage on a cosmetic scale.
How to get rid of errors
Now that you have a good idea of what insects or pests are infesting your azaleas, here are some of the best ways to get rid of these insects.
Remember to isolate your azalea from other plants if possible to prevent insects from spreading to other plants before treating them.
insecticidal soap
Using insecticidal soap is one of the best ways to get rid of azaleas because it kills most insects on contact.
All you have to do is spray the soap on your azalea making sure to cover all areas and get rid of the pests all at once.
You may need to spray more than once to ensure all bugs are dealt with.
A great advantage of insecticidal soap is that you can not only buy it online or in stores, but you can also make it yourself by combining the following household items.
- 2 tablespoons pure liquid soap
- 2 tablespoons vegetable oil
- Dilute in 1 gallon of distilled water
- Add to a vaporizer
Keep in mind that you may need to spray regularly to get rid of the bugs if they come back frequently, as it won’t last forever.
take oil
Neem oil works like an insecticidal soap, as the oil coats the insects and prevents them from breathing.
Neem oil is one of the best ways to get rid of insects on azaleas because it not only kills them on contact, but it also acts as a repellent against future infestations.
Plus, you can use it as a fungicide if needed.
Please note that you may need to spray this product more than once or at regular intervals to achieve the best treatment and prevention results.
Also, be sure to only spray neem oil when your plant is in shade or at night, as it can scorch the leaves if exposed to the sun before it dries out.
Finally, be sure to cover all parts of your azalea so you don’t miss any potential places for insects to hide.

cotton swab and isopropyl alcohol
If you have cotton swabs or rubbing alcohol, you can dip the cotton swab in rubbing alcohol to clean the leaves.
You can target all parts of the leaves or the insects themselves if you find them, as both methods will be quite effective.
However, it can be a bit annoying, so keep that in mind if you decide to use this method.
water pressure
Now, if you don’t have pest control products on hand or any of the household materials that can be used, you can use a garden hose or the like to provide water and pressure to spray the insects on your azaleas. . .
This can be effective against a wide range of pests, but leaf miners, for example, would not be treated well with this method.
This method is only good to use while waiting for better treatment products, because it’s better than nothing while waiting.
Be sure to spray the whole plant and with enough pressure to spray the insects, but not so much pressure as to break the leaves.
Prevention tips
Now that you know the signs and types of pests and how to get rid of them, it’s important to know how to prevent insects from appearing in the first place.
Here are some helpful tips for preventing insects on azaleas.
- Provide a clean growth environment.
- Provide good air circulation
- Control humidity
- Don’t Overwater Your Azaleas
- Prune diseased leaves
- Use neem oil as a repellent
- Isolate other affected plants
- Regularly inspect your azalea if any unusual signs appear
