How to Prevent Pigeons from Perching on Windows and Balconies

Lourdes, from Pamplona, shares her experience with the anti-pigeon liquid repellent “AviFin Liquido” to prevent pigeons from perching on windows.

I live in Pamplona, on the sixth floor of a residential building. For years, I have had many issues with pigeons perching on my apartment windows and making a mess.

I’ve tried everything to keep pigeons away: owls with rotating heads, discs, tapes, spikes… But there was no way to scare them off. Specifically, with the spikes, unless you cover the entire area with them, they don’t do much good because the pigeons just gather around. Additionally, it is difficult to attach them to stone or cement surfaces. We tried anti-pigeon spikes for a while, but the pigeons would still gather around. Then, some of them came off during the rain, and now we have glue stains on the stone.

One day, I noticed that pigeons had nested on the building’s facade, in an inaccessible area but close to one of my apartment windows. That’s when I decided to look for a better solution to prevent pigeons from perching on windows.


I started using the BirdGard Iberia “Avifin Liquido” Pigeon Repellent in November 2020. I have been using it continuously for over a year now. So, I can confirm that AviFin Liquido anti-pigeon repellent works.

I spray the windowsills, where the pigeons perch, every 10 to 15 days or so. When you apply the anti-pigeon liquid, it smells like mint. So, it’s easy to tell when it’s time to reapply because the scent fades. Water eliminates the effect of the anti-pigeon liquid repellent. So, if it rains, I reapply the AviFin Liquido.

In my case, having several windows where pigeons perch, one bottle of AviFin Liquid lasts me over a month.

With consistent application, the AviFin Liquid anti-pigeon repellent works very well. After my positive experience, I gifted a bottle of AviFin repellent to my sister, who also had issues with pigeons perching on her balcony, and it has worked wonders for her as well.

Out of all the methods I’ve tried to combat pigeons: owls, discs, tapes, spikes… the anti-pigeon liquid has been the most effective. So, I recommend it, as long as it’s used consistently, of course.
