They get pretty brave here but most of the time when the light comes on my dogs are out the door so that may give them even more reason to leave the area, our duck houses and coop's are right next to our house. Which makes it pretty easy to chase something off. I only caught the one raccoon walking up the ramp with the pred light flashing but I will say this that coon had it's head down like it was avoiding the light but was still walking right up the ramp anyway. Also had an Owl land on the ramp with the light flashing. I was very disappointed that some of them stopped working after after about 6 months too, and of course I misplaced my receipt so couldn't send them back
