As we all know, a great deal of what we see on social media is simply made up, but the meme here is spot on, as I know from personal experience.
I needed to rid our ranch of ground squirrels, because their holes represent a danger to the horses. I built and installed a couple of owl boxes as an adjunct to a few other steps, and within the few weeks, the problem had vanished.
A great many local farmers around here (central California) have gone in this direction as well.
