Spider mites suck sap from the plant and thus quickly create wreak-havoc on the house and outdoor plants. They feed by piercing leak tissues and sucking up fluids and nutrients of plants. Thereby, they cause damage to leaves and stems.
Dry and hot climates make the perfect condition for spider mites to thrive. However, they feed on indoor and outdoor plants year-round in some parts of California. They deteriorate the strength and nutrition of plants and trees, making them susceptible to tree diseases and insect infestation. So, before planning any defense mechanisms, a professional arboricultural consultation is crucial.
