Ash trees of all varieties are under constant assault from common pests such redheaded ash borers, Asian long-horned beetles, and carpenterworms. These insects cause slow decline in ash, and merit concern and eradication. However, the most recent and pernicious pest is the Emerald Ash Borer (EAB), which has proven to be fatal after just a few years of infestation. The EAB, and the aforementioned pests alike, can be controlled and wiped clean of your ash trees with our proven systemic insecticide injections. ASK ABOUT OUR 2-YEAR CONTROL PROGRAM!
Here are just a few of the most emergent pest problems that you may commonly find on your property. Please be aware!

Be Alert to the Bagworm!
The bagworm insect (Thyridopteryx ephemeraeformis) is a notorious menace to many evergreen species, such as spruce, arborvitae, and junipers. Bagworms both populate and feed voraciously from late May to the end of August, leaving severe defoliation and ugliness in their wake. If an infestation is left unchecked, the affected tree may not survive, or be left disfigured and bare of needles at best.
Treatment is best applied on the bagworms from late May through July, while the bagworms are still feeding heavily and thus vulnerable to our proprietary blend of effective insecticides. With our treatment, they will be stopped in their tracks within hours of application, guaranteeing bagworm-free trees for the remainder of the season.

Kermes scale, Pin Oak scale, or Allokermes Galliformis are just a few names for the latest pernicious pest to invade our neighborhood trees. Most likely to be affected are Pin Oaks and Red Oaks, though most oaks are at some risk. The life cycle of scale is complex, and often goes unnoticed due to scale’s small size. However, their presence is disturbingly observable beginning in midsummer as evidenced by “flagging” of leaves (center picture). These clusters of brown leaves are a result of heavy feeding by females, whom encase themselves in a waxy shell (top right). Disguised as buds and blending in with bark, they insert their stylets, or sharp mouthparts, to siphon off the sap via the phloem. Thus, nutrient transport is disrupted, which first manifests itself as unsightly flagging. The lifecycle continues in September as eggs become fertilized in the brood chamber (bottom left), and heavy damage ceases momentarily until next spring when the next generation wreaks havoc. If left untreated, infested oaks will exhibit dieback, slower growth rate, and greater susceptibility to other diseases and pests. In severe cases, the tree may become overwhelmed and die.
Fear not! We can deliver control and eradication via systemic insecticide, ideally applied from May through August. Call AB Tree & Lawn for assistance with all your tree care needs!
