This office also provides arthropod management advice, tick identification, and referral for tick testing. Inquiries and samples can be submitted via phone, email, mail, and in person.

  • All specimens should be submitted in crush proof containers. In addition, the submission of spiders should be in a container of
    alcohol that is leak proof. Please be sure the container is well packed. If samples arrive in poor condition it may be necessary for
    us to request additional specimens. Mail packages to arrive on weekdays.
  • Intact ticks, mosquitoes, and other blood-feeding arthropods are acceptable submissions, but we cannot accept any public
    submissions of human or animal blood, mucosa, feces, or other tissues. Medical samples must be submitted to us through a
