Cobweb-forming mites can severely damage plants by sucking sap and causing visible damage and withering. These pests can be introduced through contaminated clothing, pets, or imported plants, and can rapidly spread in hot, dry weather. While synthetic insecticides like bifenthrin or permethrin can effectively control mites, they also harm beneficial insects. Natural pest control can be achieved through companion planting with strong-smelling plants like dill, coriander, and garlic, or by growing chrysanthemums, which contain pyrethrum and strongly repel mites.
