This building manager in Cape May Court House, NJ was having a serious issue with birds roosting on the high beams in his warehouse and defecating all over the place.
Birds and their droppings can carry over 60 different types of diseases and, if disturbed, can be transferred to humans just by being around the droppings. The most infamous disease is Histoplasmosis, which is a respiratory disease that results from a fungus growing in dried bird droppings.
Besides being direct carriers of disease, birds and their nesting carry a plethora of parasites, most notoriously bird mites. Bird mites are parasites that feed on blood. When birds leave or abandon their nests, the mites are left behind without a suitable host for their next blood meal. If disturbed while removing they will make their way into a building and feed on humans.
We carefully removed the birds' nesting materials and applied a product that specifically targets bird mites. Next, we installed optical gel along the beams throughout the warehouse to prevent the birds from roosting. The optical gel is a multi-sensory bird repellant that deters birds using sight, smell, and touch. As a visual deterrent, the birds see a UV spectrum that, to them, looks like fire or smoke (although there isn't any). As a smell deterrent, the optical gel gives off a cayenne pepper or peppermint odor that the birds hate and as a touch deterrent, the optical gel has a tacky feel to it that the birds dislike.
Now the building owner can continue his operations in a safe, disease-free, and nuisance bird-free work environment.
