A bug never before seen in Idaho now lives in Ada and Canyon counties.

The Idaho State Department of Agriculture has reported the discovery of this new invasive insect, the Elm Seed Bug otherwise known as Arocatus melanocephalus. Here is communications director Pamm Juker  with details: “ The Elm Seed Bug has recently been confirmed in Idaho in both Ada and Canyon counties. Elm Seed Bugs, which have never been found before in the U.S., are commonly distributed in central-southern Europe and feed on the seeds of elm trees. The insect does not damage trees or buildings, nor does it present any threat to human health. However, due to its habit of entering houses and other buildings in large numbers to escape the summer heat and later to overwinter, it can be a significant nuisance to homeowners. If you suspect you have found the Elm Seed Bug outside of Ada and Canyon counties, please place 4 or 5 specimens in a plastic sandwich bag and mail in a regular envelope to: Idaho state Department of Agriculture, Plant industries Division, P.O. Box 790 Boise, ID 83701”

Since the Elm Seed Bug is new to the U.S., the United States Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) will take the lead in researching the biology of the pest and its possible impacts, and will develop recommendations about management. Homeowners in Idaho may contact their county’s University of Idaho Extension office for information on dealing with the insect.  To locate your local Extension office, please visit http://www.uidaho.edu/extension/about. The Idaho State Department of Agriculture will continue to track the movement of Elm Seed Bug as it is found throughout Idaho.
