is kings cages no chew safe?

[newbirds]

My 8 lovebirds ravage any type of decoration/plant we have in our living room, I have tried training them against it but with 8 lovebirds it is extremely overwhelming, I tried to do it one by one but as I needed to stay consistent I really couldn't, so I started searching and found this spray called "King's Cages No Chew", is it really safe and non toxic for birds?

I question what makes it effective, as parrots don't have a very good sense of taste.

None of that really tell me why it works though, nor if it is safe.

I’m curious how it’s safe if it says to keep away from the facial area…. beaks are part of the face.
I’m also curious how it works bring as taste is less developed in parrots than what we see in mammals.

If I were in your position I think I would find it would be easier to remove the plants and things that can’t be chewed to a room the birds don’t occupy.
