If you do treat, garlic sprays may be an option. Most trees are going to be too big for spray equipment that is available to the homeowner to reach. You can treat for wooly aphids, but most likely it would be a job that would need contracted out. Aphids will rarely cause enough damage to a tree to kill it, and the infestations tend to not happen yearly. Luckily this is the case with other wooly aphids. You may also notice the white wax on the ground below the tree, as I did at Minnetrista. In the case of wooly aphids, you will also see the sticky, white wax substance they excrete for protection on the leaves and bodies of the aphids. Usually easily seen groups of aphids on the underside of the leaves. Sooty mold, a black fungus may be present on leaf surfaces. Honeydew, the sticky substance aphids secrete as waste, can be found on surfaces below the tree and leaves may be sticky. Stunted, curled, yellowed and distorted leaves. The signs of wooly aphid damage are also similar to other aphids’ species and can include the following: Wooly aphids will feed on leaves, stems, and twigs.
