How can I effectively manage plant pests using scales on my garden plants?

To effectively manage plant pests like scales on your garden plants, you can use natural predators, such as ladybugs or lacewings, to control the scale population. Additionally, you can prune and remove heavily infested plant parts, and use horticultural oils or insecticidal soaps to suffocate and kill the scales. Regularly inspecting your plants for signs of infestation and taking prompt action can help prevent the scales from spreading and causing damage to your garden.
