On the research front, there are a LOT of products out there (not integrated like mine) disturbingly selling rather well!! There are about 20 scientific articles suggesting these DO NOT WORK :( Just the 1974 ONE that suggests they do! This is one of many claiming a blind test shows no proof of it working: http://www.ncbi.nlm.nih.gov/pubmed/10890136
.....
... so for my product improvement phase, I am thinking of finding a way to add other options such as Bear/Cougar/Rodent repulsion ultrasonics (which DO have scientific proof of working) or a Citronella band to the screw-on plastic reflector retainer - using something like this as a base: http://www.amazon.com/Citronella-Insect-Repellent-Wrist-Amount/dp/B005V6AHF6/ref=sr_1_9?ie=UTF8&qid=1367732704&sr=8-9&keywords=citronella+wrist+band

Need to expand scope of repulsion options ref:http://www.bugjammer.com/reports/coro/index.htm
Note from Alex Wilks: Challenge THeory:p.s. I just did a quick Google and found this: http://www.bbc.co.uk/news/magazine-20669080. Don't mean to ruin your plans before you've gotten started but thought you may just want to check that the research backs your idea up first?

Range
- According to Washington State University, the sounds from ultrasonic pest control devices don't carry far. They lose about half their energy within 15 feet and are ineffective at 30 feet. Objects placed in the way of the sound, such as a couch or table, can also block the device's effects. This could permit pest animals to hide behind large pieces of furniture to avoid the sound. Rodents are already prone to run along walls and under furniture for protection from predators, which decreases the effectiveness of most ultrasonic repellers.
- According to Rat Behavior, ultrasonic frequencies are sounds above 20 kHz (or kilohertz, a measurement of radio frequencies)–anything higher than a human can hear. Rats and other rodents are capable of hearing up to around 90 kHz. Dogs can hear up to 40 kHz and cats up to 60 kHz. This means that many of the ultrasonic frequencies that can be heard by pest animals can also be heard by pets in the home, especially if those pets are related to the pests homeowners wish to drive out.
