Join us for an exciting evening searching for and learning about scorpions! We'll discuss interesting information about these arachnids, including their food sources and ecosystems, plus methods to naturally keep these little critters away from your home and other structures. As we hike the trail, we'll stop to watch the scorpions glow under our black lights!
