Get out your field guides and practice your pest management knowledge by clicking on the GUESS THE PEST logo or following this link www.udel.edu/008255 and submitting your best guess. For the 2021 season, we will have an “end of season” raffle for a scouting toolkit for one lucky winner, and five winners will be sent a small jar of locally produced honey. Remember, you can’t win if you don’t play!
