Works great for log cabins
I have a log cabin and we had a carpenter bee infestation. The bees were lighting up the house and garage with holes everywhere. We used to have pest control come out and spray powder in the holes for 3 years and that NEVER worked. Then I found the traps. The trick with these traps, is make sure to place them every 15-20 feet, and seal up any holes in your home/garage so they are forced to go to them. Bees dont want to make new holes, its too much effort. Thats why the traps work. It also helps to catch a dead carpenter bee and put one in the trap. But once you do that, then they fill up. Its the only thing that has ever worked. We stopped seeing new holes. Had the traps up for 5+ years.
