These guys did a great job. I have several solar arrays due to the configuration of my roof. They surrounded each with a wire cage after cleaning the astounding amount of pigeon droppings and nesting materials. The also installed some spikes in areas that might otherwise become a new pigeon haven. They did a great job of cleaning up the entire area when they were done. The pigeons hate these guys but I’m very grateful to be able to walk out my front door and not have to fear a dropping blizzard or stepping through pigeon droppings. Thank you so much for your help!
