Although woolly aphid populations barely get big enough to hurt most plants, the curled and distorted leaves they create and leave behind are unappealing. It is essential to know how to get rid of aphids.
What are Woolly Aphids?
Woolly aphids are one of 3500 various types of aphids which might infest your garden. These aphids vary mostly in appearance from others.
Like all aphids, these pests are tiny, typically growing no bigger than a quarter inch long. Like their many cousins, they create damage to plants by draining out the sap.
Woolly aphids are usually green or blue in color, and somewhat fuzzy. Their covering of a white, waxy, material gives them some shelter against the elements, and in some instances against pesticides.
Much like other sorts of aphids, these sap-sucking insects are little. Woolly aphids look fuzzy because of the waxy and white material that covers their body. These insects use two hosts: one for feeding in summer and one for overwintering and laying eggs in the spring.
Woolly Aphid Damage
Aphids usually feed in groups. They can observed feeding on buds, bark, foliage, twigs, branches, and roots. Damage is detected by yellowing foliage, branch dieback, the curled and twisted leaves, bad plant growth, or the development of cankers on the roots or branches.
Sometimes, wax accumulation is seen along with the sticky, sweet residue referred to as honeydew. Also, plants might get covered with sooty mold.
Woolly Aphid Control
Though this does not typically damage or affect the plant itself, getting rid of the aphids and their honeydew will aid in regulating the sooty mold. Since extreme woolly aphid attacks rarely happen, there is little need for woolly aphid pesticide.
Typically, their numbers remain low with natural predators like hoverflies, lacewings, ladybugs, and parasitic wasps. If desired, you can spot treat where the aphids are plentiful using neem oil or insecticidal soap. Also, you can trim out and kill infected branches.
When chemical control is believed to be necessary, a woolly aphid insecticide like acephate can be used to regulate these insects. Contact Hickory Tree Care to apply a woolly aphid insecticide treatment if necessary.
