ANN ARBOR, MIANN ARBOR, MIAphids are small sap-feeding insects that often gather on tender new growth, stems, buds, and the undersides of leaves. On landscape plants, the first clue is often not the insect itself but curled growth, sticky honeydew, sooty mold, or ants moving repeatedly over an infested plant.
Honorable Pest Control provides aphid inspection and targeted treatment for ornamental plants and landscaping within its published Southeast Michigan service area. The right response depends on the plant, the amount of aphid activity, visible damage, beneficial insects already present, and whether the infestation is on ornamental or edible vegetation.
Aphids occur in many colors and species, so identification should be based on the insect, host plant, feeding pattern, and damage rather than color alone.
A few aphids on an otherwise healthy, established plant are not automatically an emergency. Michigan State University and other integrated pest management guidance note that aphids have many natural enemies, including lady beetles, lacewings, and parasitoid wasps, and these beneficial insects can suppress colonies outdoors.
Treatment becomes more reasonable when colonies are increasing, new growth is being distorted, honeydew is creating a property nuisance, valuable ornamentals are under repeated pressure, or the infestation is not improving with practical nonchemical steps.
Aphids excrete a sugary liquid called honeydew. That residue can coat leaves and objects beneath an infested plant, and fungi can grow on the honeydew to create the dark coating commonly called sooty mold. The mold is a secondary result of the honeydew rather than the aphid feeding directly producing black mold in the plant.
Ants may feed on honeydew and protect aphid colonies from predators. That relationship can make an aphid problem more persistent, but aphids do not automatically mean every ant colony on the property needs treatment. Honorable inspects the actual ant activity and recommends a separate ant control step only when it is warranted.
Identify active colonies, plant damage, honeydew, sooty mold, ant activity, and beneficial insects already feeding on the aphids.
Ornamental shrubs, trees, flowers, vegetables, herbs, and fruiting plants can have different pesticide label requirements. Tell the technician when the affected plant is edible before a product is selected.
When treatment is appropriate, use a product labeled for aphids and the specific application site, following label directions for rate, coverage, timing, and pollinator precautions.
Aphids can reproduce quickly and may be protected inside curled foliage, so follow up should be based on remaining activity rather than a blanket promise that one application permanently prevents them from returning.
Aphid treatment is not harmless to every beneficial insect or pollinator. Product choice, plant type, bloom status, application timing, weather, and label restrictions all matter.

Aphids feed on plants, not people or pets. The main concern around homes is plant damage and the honeydew, sooty mold, and ant activity that can accompany a larger infestation.
Light aphid feeding often does not kill an established plant. Heavy or repeated infestations can curl or distort new growth, reduce plant vigor, and create significant honeydew. Young, stressed, or high value plants may need closer attention.
The sticky coating is usually honeydew excreted by sap feeding insects such as aphids. Check the undersides of leaves and new growth for active colonies.
A labeled insecticidal soap is different from household dish detergent. Dish detergents can injure plant tissue, especially at the wrong concentration or in stressful weather. Use products labeled for the plant and pest and follow the label.
If aphids are clustering on ornamental plants, coating surfaces with honeydew, distorting new growth, or returning faster than practical garden measures can manage them, Honorable Pest Control can inspect the affected area and explain the treatment options that fit the plant and property.
