    How to Submit a Sample to the UPPDL

    Identifying the arthropod (insect, spider, mite, etc.) or disease affecting your plants is the first step to proper control. When submitting a sample, please complete the fillable submission form (pdf format), print, and include with your sample. You may also print the form and fill it out with a pen or pencil, or add additional information to a form completed and printed from your computer. Your sample will be discarded when a final diagnosis is reached.

    We highly recommend including printed or digital images to accompany any submission. Images may be sent via email, or printed and included with the sample. Ideally, you should take images encompassing a range of perspectives, from close-up to over-all pictures of the yard where the damage is occurring.

    Pictures can be emailed to

    There is a $7.00 fee for both walk-in and mail-submitted arthropod and plant disease identifications. Payment can be made with cash or check. Make checks payable to the "UPPDL". Additional charges may apply if high-cost tests are needed to make a diagnosis (for plant diseases). Clients will be contacted for approval before additional testing occurs.

    New Diagnostic Fees

    Identification of virus diseases may require additional testing. The cost for these tests is not covered by the $7 fee. The tests run from $30-200 per sample depending on the test. You will be notified if additional tests for an exact identification would be required. If you choose to do additional testing, we will let you know how much the cost is and you will have to pay the fees.
