Pigeon droppings are unsightly. Nobody likes to see or walk on pigeon droppings. People can slip and fall where pigeon droppings accumulate. When pigeon feces are fresh or rained on it is slippery.  Protecting your beams from pigeons roosting, exclusion is the best solution to pigeon problems on structural beams.  

Pigeons, like most birds, are attracted to places that provide roosting and nesting opportunities, food, and shelter. Backyard decks, patios, roofs, and gutters are seen as perfect situations for pigeons to set up shop. We all know that they carry many communicable diseases and make an unsightly mess anywhere they go. Not to mention they can be a nuisance, disrupting your peaceful day in the backyard flying around, and dropping bird-bombs everywhere.

The easiest method of cleaning is prevention, and with no natural predators available to control the pigeon population, it's up to businesses and residents themselves to keep birds away from their roof. That's why many businesses decide to invest in bird spikes. Bird spikes are a simple, inexpensive option that keeps pigeons and other larger winged pests from finding any space to land, preventing them from either nesting on pop-outs and ledges or finding a place to leave their droppings. Once spikes are installed, birds can no longer roost on the roof or a perch and instead must move to a different location, saving the expense and man-hours of having to clean up an unsightly and dangerous mess.
