"Nest removal should be initiated at the first sign of nestbuilding because it is illegal to remove nests with eggs or young. Nests can be washed down with a hose. Persistent swallows may attempt to rebuild nests several times before abandoning this effort.  Frightening swallows is not effective. Repellents are not effective. An adhesive repellent used for roosting birds (Tanglefoot®) may actually improve nest adherence. The use of toxicants, trapping and shooting are against the law; swallows are classified as migratory insectivorous birds under the Migratory Bird Treaty Act of 1918. " --- Springtime Bird Questions by Barb Ogg, Ph.D., Extension Educator, University of Nebraska

Bird Problems on your property? Pigeons, swallows, and sparrows can be a nuisance in large numbers as they can multiply quite rapidly and really make a mess on vehicles, outdoor furniture, walkways, and driveways. Once they "make themselves at home" (begin nesting) on your property it is difficult to get rid of them. It is also against federal law to disturb nesting migratory birds (most notably the swallows), so your only humane alternative is to discourage birds from building their nests under the eaves of your home to begin with.

We have developed methods to prevent successive generations of birds from revisiting and roosting in various locations on your property. These methods do not harm the birds. They simply make the process of future "nest-building" difficult so they go elsewhere in the neighborhood. The materials used are installed in a professional and workmanlike manner and are practically invisible from the ground. The installation process also involves removing abandoned nests and the buildup of bird droppings and carcasses associated with them.
