Bird control

I am looking for a hand held laser to scare away birds from the local airport here where i live. I had a hulk green laser but totally died. So now i need a new laser.
My questions are;
What is the best color to use to scare the birds?
Which is the best brand to use? And lastly is there
any American companies that are good that i can order
From so i dont have to wait for weeks to be shipped from China?

Thank you in advance for any help on this.

There's a massive bird problem where I live.
I use a 300mW 532nm laser with a small beam. Just point it on the ground next to them and they will fly away. Works on most birds.

Check out laserglow, they are in Canada.

So can I buy that dead green for $20?

What was its power?

I was planing on getting it fixed later. It was a 250 mw
