Long term test of ultrasonic pest control devices

This test consists of a large number of long term overlapping non-scientific tests stretching over a period of more than 20 years.

Objective of study
To establish the long term effect of ultrasonic pest control devices with random sound emission for a period of 730 days (2 years).

Choice of subjects
More than 112000 customers favoured us with their trust since 1987.

Materials and methods
The ultrasonic pest control devices tested are close to 10000 units of Topo Stop E50, E250 and E500. The test method has in each individual case been performed according to manual.

Experimental design
AB Soveco International offers up to 2 years Money-Back-Guarantee (no questions asked!) for all ultrasonic pest control devices and so the test period for each individual element (customer) is set to 730 days (2 years).
If a test subject in any way is dissatisfied with the pest control result he will claim the M-B-G for a refund. This will in turn indicate that this particular test element has been unsuccessful. On the other hand those test elements (customers) not taking advantage of the M-B-G must be considered to be successful. One might argue that customers not entirely satisfied don´t bother to claim the refund guarantee out of shear laziness. This might of course be true for a device costing less that $30,00, but for an ultrasonic pest control appliance costing in excess of $ 100,00 very few would be financially affluent enough not to bother claiming the M-B-G!

Yet another argument is that 730 days (2 years) is too short a time span to really establish the long term effect of a ultrasonic pest control device. Let us assure you that we through the years, have had thousands of satisfied customers coming back after 3, 5 or even 10 years to order yet another device for someone in the family. They all vouch for that their house has remained rodent free since more or less the first month they made the installation! Besides, the argument about the time span is not really fair since rat poison very seldom have any long term effect beyond two months!

Evaluation of Results
For the full test period of nearly two decades data show us that in the early years the M-B-G was being claimed in between 2-3% of the test element cases (customers). As knowledge among people about how to implement ultrasonic pest devices at best has grown considerably since 1987, the M-B-G claims have in consequence dropped to less than 1% of the test element cases in later years. Thus more than 99% of the test elements have not responded to the M-B-G in recent years.

Conclusion
With all test data on hand as summarized above, high tech ultrasonic pest control on a non-biased comparison basis must be deemed to be superior to any traditional rodent control method.
Even though their could well exist a grey zone of let´s assume 5-10% so called "affluent elements" that haven´t bothered to take advantage of the M-B-G, one must still acknowledge the fact that modern ultrasonic pest control technique with random sound emission is an effective and environmentally safe tool for controlling rodent pest.

Validity of test
The fact that AB Soveco International, despite the two year Money-Back-Guarantee still exists as a company and flourishes is the bottom line proof that this long term test of high tech ultrasonic pest control appliances has a bearing.
