These are traditional & modern fruit fly catchers, both on the job for the same length of time. Modern on the left, with a single-use adhesive pad that’s $20.00 and eats electricity. On the right, the traditional fly catcher is fueled by apple cider vinegar @ $0.02/use and just eats bugs. It's far more effective and far less expensive.
More specifically, the traditional bug-catcher is 3 orders of magnitude less expensive and at least 2 orders of magnitude better at its job. Net effectiveness is therefore 100,000 times greater and that doesn't even count the appliance cost or the electricity cost. Put another way, this is a classic example of Gizmo Green on the left and the Original Green on the right.
The Original Green is the sustainability all our ancestors knew by heart, and that kept humans alive and expanding in wisdom, range, and skills until the Thermostat Age, when we thought we could just flip a switch and make everything OK. The Original Green is based deeply in the rules of nature, because in the beginning of civilization, nature's resources were all that was available for humans to use to survive and later to thrive. Much nature-based wisdom has come down to us today if we want to see and hear about it, like the bug-catcher on the right. Vinegar is as old as civilization itself, and its attractiveness to fruit flies is likely as ancient as well. The only new tech is the Saran Wrap Wanda perforated with a fork (ancient tech) to get the cider smell out and the fruit flies in, and the rubber band that keeps it atop the ceramic bowl.
Gizmo Green, on the other hand, is based on novelty. "New & Improved" is its lowest threshold, with "Amazing New Innovation That Will Change Your Life" being on the high end. Whatever the sales pitch, because it's sold as being better stuff, it's definitely more expensive than what you've previously used to do the same job. Gizmo Green stuff more adept at getting into your wallet is that which is billed as "Smart." Everything Smart is electronic and likely connected to the "internet of things." And of course they need regular operating system or firmware upgrades, but if your version doesn't support the latest software, it's outtadate and therefore obsolete. Refrigerators manufactured in the 1950s are still running in the USA today, but if you have a "smart" refrigerator, its shelf life is probably measured in just a few years, not decades.
The Original Green and Gizmo Green divide sharply on what's smart or not. Original Green techniques since the beginning were developed by humans who were getting smarter, or at least more clever, and humans had to be thoughtful enough to operate their innovations. Gizmo Green, on the other hand, is based on the premise that its gizmos will do everything for you, so the humans can be stupid, or at least careless about how the tech works. So choose smart over stupid; durable over soon-obsolete, and more natural over more artificial, and the Original Green will serve you well. It always has.
