Don't buy it. It smells strong and does nothing. I don't know how healthy it is to smell it. I still have the smell of it.

It doesn't do any work at all. I spray a lot, it drips, and after half an hour, pigeons come back and sit again. Only in the first few days did it take an hour for them to return, now it takes ten minutes.

Extremely effective!
I had a serious problem with pigeons on my balcony. I identified the spots where they sit and applied vaseline (I read online that vaseline is an effective way to get rid of pigeons) and then sprayed this spray! No pigeons have appeared on my balcony for two months now!

Very good, I spray it on the fences and luckily it doesn't damage them... not even a problem with the plants. The pigeons didn't come back.... Of course, I recommend it!
