Remove mealybugs and scale using cotton swabs dipped in alcohol. Spraying the plant with a dilute alcohol solution (1:3) may help control pests that are not easily visible but the solution may damage the epidermis of sensitive cacti and succulents. Test a small area before spraying the entire plant.
Just so, how do I get rid of scale on my plants?
Remove existing scale on houseplants by rubbing gently with a facial-quality sponge or cotton swab dipped in rubbing alcohol. The alcohol alone should kill the scale, but the dead insects will remain on your plants and make it difficult for you to scout for new infestations.
Keeping this in view, can plants recover from scale?
They feed on the sap of plants, and a large enough population can weaken a plant, damage it or even kill it. Scale can be difficult to detect. Once the insects settle down to feed and pierce the plant’s tissue with their needle-like mouth parts, they never move again and become firmly attached to the leaves or stems.
How do I get rid of scales?
When the scale feed on the sap, they ingest the toxic insecticide and are killed. Acephate, imidacloprid and dinotefuran are three commonly used systemic insecticides that are effective against scale.
Neem oil is a godsend. Not only does the oil coat plants, but it naturally contains azdirachtin, which will slowly poison most soft scales and mealybugs. You can use it on armored scales as well, but it will work like a horticultural oil in that usage.
Remove light scale infestations by scraping them gently from the surface of the leaf with your fingernail or pruning out leaves if the scales are localized. Sometimes applying alcohol to the insects will make them easier to remove, but be careful not to get any on the plant.
