The commercial application for ultrasonic rodent repellers is extremely diverse. Virtually any business which experiences on-going rodent problems can potentially benefit from incorporating this technique into its rodent management program.
Conventional traps of all types and toxic baits serve only one purpose; to kill the existing target species. Killing the rodents may be satisfying but it cannot cure the problem long term as anyone involved in facilities maintenance well knows. There are always more rodents outside waiting to come in to replace the population killed. The cycle is endless because the "carrying capacity" of the space has not been altered. Carrying capacity is the ability of a given space to support a given number of rodents with food, shelter and water.
Rodents will maintain the optimum carrying capacity of a space by killing young and reducing breeding cycles if the population gets too high and aggressive males prevent the incursion of new outsiders. Similarly, when the population is decimated by trapping or baiting, the remaining animals will increase breeding cycles and new outsiders will be allowed to come in. This is simple survival of the species biological response. Rodents are at the bottom of the food chain; everything eats them, so they are well adapted to survive.
One survival adaptation that they possess is the ability to communicate in a range of sound that their predators cannot perceive. That range is ultrasonic. Rodents have the ability to emit and receive sound from 20,000 cycles per second (20Khz) to 90,000 cycles per second (90Khz). This ability is precisely what gives we humans the opportunity to alter the environment of the space to make it inhospitable for rodents and therefore break the re-infestation cycle.
Ultrasonic rodent repeller introduces into a given unobstructed space complex an intense ultrasonic sound in the 32-62Khz range. The level of noise in the ultrasonic range creates auditory stress which can be disorienting and even painful. A disoriented rodent is a rodent vulnerable to predators and that is not acceptable as a survival strategy. The net result is that that particular space will no longer sustain a rodent population and your rodent management program makes real strides forward. This technique is not magic, it simply capitalizes on biological responses known to exist.

Using the technique properly for maximum success
Trying to blanket a warehouse or any other facility with ultrasonic sound rarely works well because the units have to be mounted in the ceiling and there will be too many sound shadow areas created by materials stacked and stored in the warehouse.
The correct solution to the problem is to treat the entry points for the rodents and/or treat the perimeter of the building. If the building has a cement floor, a solid foundation and good solid walls, just treating the entry points is usually all that is required. Entry points are delivery doors, employee entrances and any other opening to the outside. Rodent Repeller units are placed either facing toward the entry point from up to 3 meters away or placed so that the speakers face across the entry point at a 90 degree angle. Units should be placed about half a meter off the floor.
If the building has a poor foundation or walls with lots of holes for entry you must treat the entire interior perimeter of the building. Units are placed about 5 meters apart around the inside wall facing along the wall (90 degrees. to the wall) toward the next unit in line. In a square 8,000 sf facility this method would require approximately 22 units. If only the entry points need to be treated, it could require far fewer.
Now the question is: Yes, but what about the rats already in the building? Will entry or perimeter treatment get rid of them? The answer is no. What the treatment will do is prevent new rodents from coming in after they trap out the ones that are currently inside. The technique of using high frequency sound changes the environment of a space treated with the sound to make it a place which rodents do not find hospitable.
Here is the problem with poisoning and trapping. Any space can support a specific number of rodents with food, shelter and water; that is called the "carrying capacity" of the space. In a house that can be perhaps 10 mice or rats, in an 8000 sf warehouse it could be 200. The rodents claim the space as their own and will defend against others from the outside to maintain the "carrying capacity". If they are killed off and the number drops below the carrying capacity level two things will take place to restore the desired number: 1. New rodents from the outside will enter and be allowed to stay. 2. The survivors will breed more rapidly to restore the desired number. This is basic biological survival of the species behavior.
The above is the reason that trapping and poisons can never achieve an end to the problem. There are always more rats outside to replace the ones killed inside and they will keep coming in until something changes in that building to make them unable or unwilling to enter. Making a building unable to be entered by rodents is extremely difficult--even the White House in Washington has a huge rodent problem. Making a building one which rodents are unwilling to enter is achievable using properly placed high frequency ultrasonic repellers.
What level of success is reasonable to expect? Even ultrasound cannot achieve 100% prevention of entry. There will always be a few rats or mice that will brave the assault on their ears to see what is in the building, consider them like humans who bungee jump off of bridges. But those few who do enter will be disoriented by the sound and much easier to trap. The real goal is to reduce an infestation which is expensive in terms of cost of lost products, damage, health hazard and time and materials used to deal with it to an easily controlled situation. Ultrasonic deterrence can provide long term benefits which make it an extremely cost effective investment.
For an 8000 sf warehouse which might require 25 units at a cost of $20 each the equipment investment is only $500. The product will last easily 10 years so the real investment cost is $50 per year. Any facility operator experiencing a rodent infestation should evaluate the overall cost of current efforts to deal with the problem, the historical cost of damaged or destroyed stored product and cost to repair rodent damage to the facility itself.
Compare that annual cost to the cost of adding the ultrasonic component to your rodent management program and the course of action is obvious. You literally can't afford not to try it. Considering the fact that the product is sold with a 90 day money back guarantee there is no good reason not to try it.
