I have been removing pigeons for both businesses and the city for just over a year now. I have a different tactic of removal than other companies would and birds are garanteed not to be harmed during removal. Another great thing about it is we are very good at removing the birds, and do it rather quickly. without poison you migh be able to get 65% of a problem... with my tactics we have been able to remove 75-100% of a problemed area without injuring a single bird. feel free to give a call today for furthat questions.
