In regards to the argument that those electronic devices are only “temporary”….no offense, but so is spraying chemicals that will linger in everyones lung but eventually wear off and need to be redone. We humans are the ones taking over natures living areas and complain about bugs and such, we are such hyypocrites!
As I just recently bought my my first house in AZ and am now faced with Roaches, which leads to to Scorpions…I WILL be purchasing the Pest Offense for following reasons:
In europe most of the common sprays here arent even environmentally allowed to be used, so why do I want to subject myself to them, furthermore, I previously used those devices in Germany and while it does not KILL the spiders, it drives them out and away, which is frankly all I can achieve in life anyhow – even if I killed a million – they survive, and good so, cuz as much as i dislike for example spiders, they do control the fly population etc….

To cut it short – electronic devices work while you use them, sprays work for what, about a year? and cost how much more? Just putting it out there….
