It doesn't. The FTC has info on these scams at http://www.ftc.gov/opa/2001/05/fyi0128.shtm. Enter "Pest Repeller" in the FTC search window for more info.
No, any rodents within the repeller's range will also be affected by it, sadly.
Electronic devices are not effective long term.
If the red light on the pest repeller stops working, it could indicate a malfunction in the device. The light is typically an indicator of when the repeller is functioning properly or emitting frequencies to deter pests. It is best to consult the user manual or contact the manufacturer for troubleshooting and potential solutions.
I don't recommend it-they are not effective long term
Electronic devices are not effective long term.
Yes, Riddex electronic pest repeller repulses squirrels (Sciuridae family). But it requires a certain range of effectiveness, beyond which it has no impact and within which other controls -- such as removing food sources and sealing cracks -- need to be implemented.
You can buy them off Ebay. They are cheaper and they ship fast!
No. It can only make the animal suffer. This devise gives off an electrical pulse that these small animals may be able to feel. Read the label on this product before using around the guinea pig.
Yes it's just ultrasonic sound, but they usually don't work long if at all so I would advise against purchase.
Emission of high-frequency sounds whose cycles are digitized to random variations and whose pitches discourage cockroaches, mice, and rats from feeding and nesting in attics and garages is the way in which the Ultrasound pest repeller works. Efficacy nevertheless requires an absence or paucity of furniture and outlets as well as a lack of such domesticated animals as chinchillas, gerbils, guinea pigs, hamsters, minks, and tarantulas whose behavior and hearing will be impacted.
No, don't buy any of the electronic repellers. Although some provide short term benefits, none has been proven thus far to work long term. Many of the big pest cos. have already tried them & no one is using them.
