Hydrangea Scale is a small, brownish-red scale insect that feeds on the leaves of hydrangeas and causes damage to the plant. The insects are spread through the movement of infested plants and horticultural material.
The hydrangea scale is hard to see as it attaches itself to the underside of leaves. It has a very small circular hole in its center where it sucks sap from the plant. This causes leaf drop, reduced flowering, and leaf curling. The scale will also cause premature leaf drop if left untreated for too long.
The best pesticide for scale is a combination of Acephate, imidacloprid, and dinotefuran. These three systemic insecticides are effective against scale and can be applied directly to the plant or sprayed onto the soil around it.
Acephate is an insecticide that works by interfering with an insect’s nervous system, causing paralysis and death. Imidacloprid is a systemic insecticide that works by disrupting the central nervous system of insects through direct contact or ingestion. Dinotefuran is a synthetic pyrethroid that works by disrupting the normal function of an insect’s nervous system through contact or ingestion.
How Do You Treat a Scale Infestation?
Treating a scale infestation is easy, but it can be a little tricky to get the timing right. We recommend using neem oil for an organic and natural treatment and prevention method, but for serious infestations, insecticidal soap may be more powerful. Simply spray the entire plant down from top to bottom (with either mixture), and wipe the foliage clean with paper towels.
How Do You Get Rid Of Scale Insects?
Scale insect infestations are a common problem for homeowners, and they can be very difficult to get rid of. These pesky pests cling to the leaves and stems of plants, sucking out their juices and causing damage to the plant’s structure. They are most often found on citrus trees, but they can also attack other plants such as roses and tomatoes.
The first step in getting rid of scale insects is to identify which type you’re dealing with. There are several different types of scale insects, each with its own unique characteristics. Knowing what kind you’re dealing with will help you know how best to treat the infestation.
Once you’ve identified the type of scale insect that’s infesting your plant, there are several different methods for getting rid of them. The method you choose will depend on what kind of plant you’re trying to save, some methods work better than others depending on whether or not it’s an indoor or outdoor plant (or both).
How Do You Get Rid of the Hydrangea Scale?
There are two ways to get rid of the hydrangea scale: by hand or with a chemical treatment. It’s important to choose whichever method is best for your plant and its surroundings, as well as what kind of person you are.
If you’re an organic gardener, then you may want to consider hand-picking/squishing/rubbing off the creatures. This can be a tedious process, but it’s also very effective. Just be sure to wear gloves when doing so, because those critters can give you a nasty rash if they get under your skin (and don’t forget the sunscreen).
If you’re more of a chemical treatment kind of person, then summer weight horticultural oil and insecticidal soap are both options that work well on hydrangeas. These products are less harsh than those designed for winter use, so they won’t damage your plant over time, but they will still kill those pesky little scales.
List of Pesticide For Hydrangea Scale
Pesticides can be used to control this pest, but it’s important to use only pesticides labeled for use on hydrangeas (usually those with active ingredients like azadirachtin or acephate). You’ll want to apply them at the first sign of an infestation (before you notice any damage or honeydew) and repeat applications every three weeks until all signs of scale have been eliminated.

Additional Info :
Hydrangea scale is a tiny, immobile insect that attaches itself to the stems and leaves of hydrangeas. It sucks sap from the plant and can cause it to become stunted and deformed.
Hydrangea scales are difficult to kill because they secrete a protective waxy coating that keeps them safe from insecticides, so you’ll need to find a product with enough power to make it through the protective layer. Look for products that contain acephate or diazinon. These pesticides will kill the scale quickly, but they can also be harmful to other beneficial insects such as bees.
