Emerald Ash Borer Treatment
Emerald Ash Borer (EAB) is an invasive insect rapidly killing ash trees in eastern Kansas, spread by the dispersion of adult beetles and the transportation of infested firewood. It's critical to treat ash trees prior to or immediately after signs of infestations are noticed, otherwise treatments may not be effective.
Treatments are done by injecting pesticides directly into the trunk of the tree. Trunk injections are fast and extremely environmentally safe.

Signs of EAB Infestation
Thinning Canopy
EAB causes tree canopies to thin and eventually die. Dieback is usually uniform but may start with one limb. It is critical to catch this early, as only 20% canopy loss can prevent tree recovery
Epicormic Shoots
New leafy shoots emerging below the canopy of the tree is a reliable sign of EAB infestation, and differentiates it from other causes of canopy loss
D Shaped Exit Holes
Adult beetles emerge from the bark after 1-2 years and create D-shaped exit holes. If exit holes are observed, nearby trees are also infested.
Dutch Elm Disease Treatment
Dutch Elm Diesease (DED) is a fatal fungal infection spread by bark beetles and root grafts. It rapidly spreads between nearby trees and must be treated before or immediately after symptoms appear. For this reason, preventative treatment is best solution for high value elm trees. Elm trees that cannot be saved should be removed as soon as possible, as even dead trees act as a repository for the disease.
Treatments are done by injecting pesticides directly into the trunk of the tree, and should be paired with removing infested trees from the community.

Signs of DED Infestation
Wilting Branches
DED begins with streaks of wilted branches, with leaves turning brown or reddish. As soon as any wilting is observed the tree needs to be treated immediately
Stained Sapwood
Brown stains appear in the sapwood of the trunk, branchs and twigs of the tree
Bark Beetle Channels
Elms killed by DED display beetle channels created by the bark beetles which spread the disease. It is imperative that dead elms are removed and destroyed to prevent the spread of these bark beetles
