What are the most common pests that damage garden plants?
The most common pests affecting garden plants include aphids, spider mites, whiteflies, and various species of caterpillars. Aphids are tiny insects that suck the sap from plants, leading to stunted growth and yellowing leaves. Spider mites can create webbing and cause leaf discoloration, while whiteflies can transmit diseases as they feed on plant sap. Caterpillars, depending on their species, can cause significant damage by voraciously consuming leaves.
In addition to these, other pests such as beetles, slugs, and snails can also wreak havoc in the garden. Beetles might chew on leaves and flowers, while slugs and snails leave a trail of silk and can severely damage young seedlings. Recognizing these pests early can help in managing them effectively before they cause irreversible damage.
