we placed 3 boxes over 2 months ago in different places on our property hoping we could catch a swarm. I had finally given up hope of catching anything this year. We were going to take the boxes down soon and I'm sure glad we didnt. I was mowing the area around this tree, looked up and almost drove in to the tree from the shock lol. We have bees! We had a hive 3 years ago but theyflew away. I'm so happy that we have bees. They may or may not stay, it at least we learned to set up a lure box.
