The FireFly WM is essentially the same as the FireFly FF, but it comes with a metal "L" bracket for mounting on wood structures. This configuration is primarily used to haze birds away from such structures.

Birds can be a serious nuisance and sometimes a hazard around wood utility poles, buildings, and other wooden structures. Their droppings create a mess and can lead to equipment damage and outages. Woodpeckers and flickers can also damage the wood itself.
The Firefly WM, employs the same bird deterring technologies as our FireFly FF, but hangs from a metal "L" bracket rather than a power line. It is easy to install using the included wood screws. Alternatively, straps may be used for installation on poles.
