The Red Spider Mite, scientifically known as *Tetranychus urticae*, is a tiny arachnid that commonly infests plants. These pests are often red or green and are known for their ability to reproduce quickly, leading to large populations. They thrive in warm, dry conditions and can cause significant damage to a variety of crops and ornamental plants by feeding on their leaves. These mites create fine webs on the undersides of leaves, which can be a sign of infestation. Control methods include introducing natural predators like ladybugs or using miticides. Regular monitoring and maintaining proper plant care can help prevent outbreaks of Red Spider Mites.
