Can human beings make ultrasonic sounds? (with vocal cords)?
I had the idea that perhaps there is a way to emit such sounds by straining the vocal cords as to make a high pitch whining sound, and then pushing a bit further up. You arrive to a point where there is no audible sound, but the air is still passing through. I had the impression I was producing ultrasonic sounds when I saw the reaction of my cat. (or was he just reacting to the flushing expression on my face?)
interesting observations….a very good question indeed…but to strain the vocal chords to such an extent is in the “impossible” catagory for average humans…but in the world there is probably someone who can do it…maybe that someone is you!

House wide spider elimination suggestions?
I live in southeastern Wisconsin (USA) and have recently been over-run by spiders. I know they do more good than harm, but walking my face into webbing while trying to get to the coffee pot first thing in the AM means they have to go!
Since I’m going to be re-carpeting the entire house the first week of August, I thought that would be the ideal time to also attack the spider problem.
Does anyone have any experience with any of the ‘bug bombs’ or any other spider eliminators that are on the market? Could you please let me know what you thought of their effectiveness? Or any other great ideas?
Also, I have five house rabbits…I’m leery of using any of the ‘ultrasonic’ devices since I’m not sure how THEY would react to it. (The bunnies are going to the sitters while I do the carpet – they’ll be gone for a week so I can set off bombs if that’s the method that works the best).
Thanks in advance for any advise!
The bug bombs work great. Just make sure you get enough to ensure every room is covered or exposed to the bomb. Also make sure you leave them undisturbed for at least the recommended time. I am sure you already know to air out throughly (after treatment) and cover anything you do not want exposed (food stuffs; yours and your pets).
I agree with your reluctance to use the ultrasonic devices. Animals cannot tell us when they are in discomfort and I would rather err on the side of safety.^
