The Insect Diagnostic Lab was established in 1978 to identify insects and insect damaged plant material from around the state. Primary service is to the county extension offices and commercial concerns. The location of extension offices in Wisconsin can be found at http://www1.uwex.edu/ces/cty.
The lab processes between 1,500-2,300 samples per year. Homeowners are encouraged to check with the local extension office for help first because many samples can be handled in a more efficient manner locally. Mail in samples, e-mails (with pictures if possible) and walk in samples are accepted. At the present time there is no charge for the service.
