Woolly aphids feed by inserting their needle-like mouthparts into plant tissue to withdraw sap. They are able to feed on leaves, buds, bark, and even the roots of the plant. As a result of feeding on the sap, woolly aphids produce a sticky substance known as honeydew, which can lead to sooty mold on the plant.
Aphids excrete a sugary liquid called honeydew, because the plant sap from which they feed contains excess carbohydrates relative to its low protein content. To satisfy their protein needs, they absorb large amounts of sap and excrete the excess carbohydrates. Honeydew is used as food by ants, honeybees, and many other insects.
Aphids can also transmit viruses and allow sooty mold to take hold. When the population becomes too large, an aphid might grow wings and fly away to find a fresh host plant.
An aphid infestation can ruin a garden. Learn what causes aphids and how to identify, kill, and control them naturally for healthy plants with no aphid holes.
