There is no known chemical or biological control of this beetle to date, so complete tree removal and sanitation is the only course of action. A total of over 300 public and private trees will be cut and chipped in Chicago this winter. Support from the City of Chicago and the USDA Forest Service is assisting with removal and replanting efforts. The adults are active from May to October. The larvae bore large holes and feed in the wood.
Female beetles chew pits in the bark of tree trunks and branches and lay their eggs there.
One of the best ways to offset global warming is to plant trees. It seems that a major factor in global warming is an increase in greenhouse gasses, especially carbon dioxide. Greenhouse gasses trap heat in the atmosphere and give the planet a fever. The process is all very slow, but some scientists believe we have already set the stage for global warming in the future. Carbon dioxide in the atmosphere has been increasing at a rate of one half a percent per year.
