Some measures I have had success with in the past.
Rat poison
Fake OWL scarecrow
Shoot them
Another effective, although expensive method for preventing roosting pigeons is the use of a commercially available bird barrier system consisting of a series of metal prongs or "porcupine wires" along a metal base that can be attached to a horizontal roosting surface. The needle-like strips of stainless steel act as a prickling fence to exclude birds permanently without harm.
YOU DO NOT NEED A 12G ALL YOU NEED IS A PELLET GUN. WHEN YOU ARE LAYING IN YOUR BED, WITH THE RETRACTABLE ROOF OPEN ON THE TRAILER. YOU CAN POP THEM OFF ONE AT A TIME..........G.
this is rough but it works. Dogs/Birds/Cats/ anything. Get three or four light bulbs and put them in a thick paper bag. Stomp that bad until all you have is glass saw dust. Take that glass saw dust and mix it with hamburger meat. Then throw the hamburger meat where the critters are. They'll eat it and cut their insides out in the process.
Slim, they are tearing up my house and also pooping allover the place. Their nests are made from concrete with tree branches and they settle under wood overhangs, causing it to deteriorate. Very unpleasant. If they were people, they would be in jail for destruction of personal property.
Slim-
My daughter would praise you.
Myself- theyre a pest.
Asked a bud with similar problem- his solution...
Catches him with a simple trap- box with a stick and string- food under box.
Sells em to a local pheasant hunter club.

I hadnt had heart to do anything other than hose them- and yes they seem to like the "bath",lol
