How do you prevent pigeons from defecating and building nests on your balcony?

This is a common question and unfortunately a common problem, especially for wildlife removal in Toronto.

Pigeons are not only persistent birds but also, they are carriers for disease. Do not believe everything you read! First and foremost, a gigantic bird statue or scarecrow will not work. This is an ineffective method to control pigeons.

Depending on the company (and where you live as local laws will dictate), you may either resolve this using humane, chemicals, or a combination of both. Try googling "pigeon spikes" and you will find some pictures of a humane way of controlling pigeons. This works quite well.
