We have a PIR light on our garage and I've noticed that in windy weather the nearby hedge moving can trigger the lights.
I used to work for a fire alarm company and one problem we had with the optical smoke sensors and detectors was with small insects getting in and reflecting more IR light into the detector diode as they moved around. this was more prevalent in buildings that were close to fields and woodland.
