What do you need help with?

Before you submit a sample, please be aware of the following:

  • Please note we charge fees for out-of-state samples, as well as several tests outside of routine diagnosis. Make sure to contact us with any questions if you are uncertain which testing is needed. 

  • We do not process human or human-related insect identification samples such as scotch tape samples from skin, hair, or other tissue samples. Insect identification samples must be a visible insect or arthropod that can be placed in a collecting jar or vial.     

  • We do not diagnose marijuana samples or photos of marijuana pests or diseases.


  • We have a new app available for digital sample submission. It is available for both iPhone and Android. Please note: we charge a fee for out of state samples submitted through the app and we do not diagnose samples from outside the contiguous United States.
