Using Your Computer to Repel Pests

Just when you thought you heard it all before (pun intended for no good reason). " Thats nothing- CowboyNeal can repel all known lifeforms just by playing his massive collection of boy band MP3s.

    If this thing can repel them, I wonder if they have something that could be used to attract them somewhere else.

    As most geeks probably realize, it's generally much easier to repel a given organism than it is to attract it.

    That would make a nifty virus. When it infects a computer, it plays sound through the speakers to attract all sorts of critters. Since the victim can't hear it, they'll never know why.

    According to a colleague at Rutgers:
    Hand-held electronic devices that rely on high-frequency sound to repel mosquitoes have become surprisingly popular in recent years .... Scientific studies have repeatedly shown that electronic mosquito repellers do not prevent host seeking mosquitoes from biting. In most cases, the claims made by distributors border on fraud.

    It's not so much that they're designed to emit sounds humans can't hear, as it is that they can't really be designed *NOT* to emit sounds humans can't hear.

    No matter what you do, you're going to be producing harmonics that may well lie outside the human range of hearing, and what with materials being imperfect, you could never perfectly limit the sound emissions to the normal human-audible range no matter how hard you tried. Even if you wanted to (and why?), there'd be the small matter of cost-effectiveness.

    Paying an extra $500 per speaker just so your dog doesn't get to hear something you can't isn't really a good investment.

  9. I've used such devices... by pieterh · · Score: 4, Funny

    In my house, which was overrun by mice when they demolished a run-down building beside us. Dozens of mice, everywhere. The device produces little high frequency clicks that drives mice totally crazy. They just love it! All the mice descended on my kitchen, where I put the thing, and ate my cat's food. The cat just watched. Finally I had to poison them with old editions of MSDN, which they chew and swallow but cannot digest. They explode in little blue puffs.
    Cockroaches and mosquitos are less common here in Belgium, where I'm writing from, but tomorrow I'm going to download Punyaratanabunbhu's (that's Puny for short) Anti-Mal and try it on the cat.
    This has to be one of the weirdest uses for old PCs that I can imagine, following my neighbour, who gave an old laptop (no HD, no battery) to his kids as a toy. It really hurt to see them drop it and squeal with joy.

      The mice demolished a building!?! Did they hire an outside contractor or did they do it themselves? Either way, though, that's definitely an effective way to get back at the prior owners for the mousetraps and rat poison.

      (* which they chew and swallow but cannot digest. They explode in little blue puffs. *)

      That reminds me of teenagers who steel raw sodium from chemistry labs, mix it with popcorn, and toss it all to birds at that beach. Once they get a taste of the popcorn, they come back for more, and the naturally-frosty-coated sodium resembles the popcorn. Thus, they mistake the sodium for popcorn, ingest it, and then explode in mid-air because the sodium hits water in their stumach. Tweet tweet Boom.

  10. Re:Darwin's Revenge by Etcetera · · Score: 5, Funny

    Such a trick may only work for so long. Eventually bugs and pests will evolve a tolerance to it. Being that bugs reproduce pretty quickly, it may only take a few years before it is ineffective I would guess.

    That's the joy of a software solution -- it can keep up with evolution.

    Download Bug Repellant 2004 - now combats Roach 1.1 and Ant 2.0

    (FWIW, products like these have been out for some time and still seem to work effectivly. They're *repellants*, not killers. The only place a large-than normal tolerance would develop and grow/multiply is among roaches that decided to live within the range of the repellant.)

    As a PhD student in animal behavior, stories like this really irk me.

    Although bats do emit ultrasound, only a few species of moths (the Noctuid moths) actually have the capacity to hear and respond to bat calls. They typically fold in their wings and just fall to the ground.

    Mosquitos have no such hearing capacity. Repeated studies by scientists and the FTC have demonstrated that the ultrasonic mosquito repellant systems fail to work as promised. Those devices, and the program described above, may be fun to tinker with, but they cannot help you.

  12. Don't just repel pests... by da3dAlus · · Score: 4, Funny

    Don't give them a reason to get near you in the first place! Take a bath every day--it's a great excuse to get away from your computer for a while (and I promise that a little soap won't hurt you). That, and why not take a minute to clean up all the soda cans and pizza boxes lying around your desk/room/office. Unless you work outside, live in a dorm, or some other run-down dwelling, I don't see why you would need to repel anything in the first place. If you are attracting rodents, maybe you need to get a little better with the personal hygiene.
