One morning while coming to the garden and finding cotton-like fibers stuck to various plants, you are aware that they are dealing with a living being. That is what we call woolly aphids.

These white fuzzy insects are very common to find in various plants in gardens and yards. They are one of the 4000 types of aphids that exist worldwide.

Like most plant lice, woolly aphids are only about 2-4 mm. They have a soft pear-shaped body. The difference is, this type has a fibrous white part like cotton.

These insects live in groups, giving the impression that the plant is full of caterpillar nests. They live by sucking plant juices, both leaves, roots, and stems. It can reduce the power of your growers.

The cotton-like part is the wax with a sticky texture when it comes into contact with other creatures. It makes predators reluctant to approach so the woolly aphids can develop freely.

The reproduction process is unique because it involves two hosts. First, the mother lays the eggs in a location where they will develop without any mating process.

After two generations of development on the first host, the new woolly aphids become adults and have wings. They also look for other locations to eat and reproduce.

Are They Damage Your Plant?

Damage may be recognized by twisted and curled leaves, yellowing foliage, poor plant growth, branch dieback, or the development of cankers and galls on limbs or roots.
The Danger of Attack Woolly Aphids

The good news is that woolly aphids do not do much damage to your plants. They eat the essence of the buds, stems, and various parts of the growers but do not cause much interference for growth.

Honeydew and Sooty Mold

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.
Sooty Mold

The attack of the woolly aphids also coincided with the honeydew. This sugar-rich substance is a waste product that they release when they inject saliva into plant parts in the feeding process.

This material does not have a detrimental effect, but it attracts many other insects, such as ants and yellowjackets.

Those creatures will participate in foraging for honeydew excretion sites so that it has the potential to cause damage.

In addition, honeydew also has a sticky nature and adheres tightly to plants. If you do not fix it immediately, this material can also cause sooty mold.

Sooty mold is a type of fungus that usually appears in locations where woolly aphids are infected. Again, it does not cause significant damage but leaves a dark mark that interferes with the beauty of the plant.
