Flir Thermal Camera for Android or iPhone
Check your bees cluster without disturbing them using thermal imaging.
Use thermal imaging to check for rodents, find clusters for effective Varroa Treatment and much more.
Beekeepers obviously want to avoid opening the hive in winter and losing all the heat that’s inside. But it’s still important to check on the bees. In summertime, bees are scattered throughout the hive, busy with making honey and feeding the young. But in the winter, they gather together in a tight knot called a “cluster” to stay warm. This cluster shows up as a hotspot that can be seen from outside the hive using a thermal camera.
