Understanding Spider Mites
What Are Spider Mites?
Spider mites are small, eight-legged creatures related to spiders and ticks. They are typically red or green and can be challenging to see with the naked eye. These pests thrive in hot, dry conditions and multiply rapidly, making early detection and treatment vital.
Signs of Spider Mite Infestation
Look for these signs to identify a spider mite problem:
- Yellow or bronze leaves: Mites feed on plant sap, causing leaves to discolor.
- Webbing: Fine, silk-like webs on the undersides of leaves.
- Stippled or speckled foliage: Tiny puncture marks from mite feeding.
