What Are Scale Insects and Why Should You Care?

If your plants have sticky leaves, yellowing foliage, or strange shell-like bumps, you’re likely dealing with scale insects. These tiny sap-sucking pests cling to stems and leaves, quietly draining your plant’s nutrients and weakening it over time.

I have dealth with these tiny insect pest over the years both indoors and on outdoor plants, what I found interesting about these little critters is they will remain motionless on garden plants what makes the perfect cammarflourge but although they are motionless the damage is being done because in this state they are feeding on your garden plants. Chemical pesticides may offer a quick fix, but often come with environmental and health risks.

That’s why more gardeners are turning to natural-scale insect control—safer for plants, pets, pollinators, and people.

Below are the top five organic remedies for scale insects, along with pros, cons, and best-use tips to help you choose the right solution.
