As an Extension Entomologist, PJ Leash spends a lot of time thinking about ticks. Technically arachnids, ticks are obligate blood feeders. This means they need to take a blood meal so they can go to the next phase of their life cycle. This means that many outdoor enthusiasts often run into them while getting some fresh air. Many people have been saying this is a good year for ticks. So I asked PJ if he's seeing the same.
