Ants Ultrasonic Pest Repeller Reviews Bell Howell Range

Ultrasonic pest repellers are electronic devices that emit high-frequency sounds designed to repel, hurt or kill household pests, such as rodents and insects.  Whether they're really constructive at doing and so has been disputed by testing labs and the U.S. Federal Trade Committee (FTC).

Left unchecked, rodents and insects tin can transmit salmonella, hantavirus and other diseases, as well every bit cause significant edifice impairment. Signs of a rodent infestation include droppings, peculiarly near food and beneath sinks, gnawed or chewed food packages, and holes in structural materials that can provide entry into the home.

Cockroach infestation, which is arguably the most pervasive and hard-to-eliminate type of pest infestation, peculiarly in urban areas and industrial and commercial kitchens, is evidenced by the pest's debris, which are pepper-like specs, typically found in kitchen cupboards, also as their egg sacs, which are often spotted in difficult-to-reach locations, such as cracks and crevices in kitchen cabinets and drains, and behind dishwashers and refrigerators.  Ultrasonic pest repellers are claimed to eliminate fifty-fifty these types of household pests.

How They Piece of work

The apply of audible sound to deter pests is an quondam strategy; the aboriginal Chinese used a number of mechanically operated sensory-repellent devices to deter rodent infestations in agricultural crops and buildings. Ultrasound, which is defined by sound frequencies beyond the upper limit of human hearing, has been used every bit pest control only over the past few decades, however.

The ultrasonic devices are plugged into a home'due south electric receptacle outlets which then purportedly emit loftier-frequency sounds that are disruptive to pests. The sound supposedly causes a physiological response known as audiogenic seizure response, which is characterized by non-directional running, convulsions, and possibly death from cerebral hemorrhage. The theory behind the devices is that confused rodents eventually flee when the disruption prevents them from gathering food, breeding, edifice nests or communicating. Ultrasonic devices are popular and appealing to consumers because of their ease of use and the fact that they are silent to human ears and allegedly eliminate the need for traps and toxicant, which are thought by some to be inhumane forms of pest control. Electromagnetic and subsonic devices are also available, and all designs vary past signal intensity, charge per unit and frequency.

But Exercise They Work?

Studies designed to investigate the efficacy of ultrasonic pest repellents have shown mixed results. One all-encompassing test performed by Kansas State University in 2002 establish that the devices were effective at repelling some insects, such as crickets, but the same devices had little outcome on cockroaches. Ants and spiders were unaffected by any of the devices. Of the pests that seem to be bothered past the noise, some tests have shown that they soon get habituated equally they realize the racket is harmless. Even models proven successful in tests are unlikely to perform fairly in real-globe situations, where signal strength speedily diminishes and tin can be blocked by walls and furniture.

Safe concerns have arisen, as well; some users take reported that the sound tin weaken the clarity of phone conversations, interfere with burglar alarm systems, and crusade muting in hearing aids. The noise may also crusade inadvertent distress to rabbits and rodent pets, such every bit guinea pigs and hamsters. Cats and dogs can hear in the ultrasonic range, but they announced not to be bothered by the dissonance emitted past these devices.

Manufacturers of ultrasonic pest repellers make claims that may be unsupported by scientific testing. In fact, more than 60 companies received warning letters from the FTC in 2001 stating that "efficacy claims about those products must be supported by scientific evidence."  Two years later, one company was sued by the FTC for violating its alert.

Nevertheless, many users accept reported success, and so customers are brash to research specific brands earlier they buy an ultrasonic pest repeller. The devices should exist placed in areas where their signals will travel uninterrupted by walls or furniture.

Better Options

InterNACHI inspectors may inform their clients that many more than reliable forms of pest command, such as chemical pesticides, traps and even cats, are effective and inexpensive.  Many InterNACHI inspectors are too qualified to perform wood-destroying organism (WDO) inspections, which can further identify and perchance diagnose insect infestation problems to help homeowners devise workable solutions.  Inspectors should e'er article of clothing the appropriate personal protective equipment when inspecting areas of a dwelling house that could be a refuge for pests.

In summary, ultrasonic pest repellers emit high-frequency sounds that manufacturers claim reduce household pest infestation, simply laboratory tests accept shown that the majority of such devices practise not piece of work as advertised, in violation of FTC guidelines.  Homeowners with pest problems should rely on a qualified inspector who can help them identify their item pest trouble and suggest them on practical and effective solutions.
