Neatmaster Ultrasonic Pest Repeller
Paranoia, paranoia, bugs and rats are comin' to get me! That's what I sang to my mama when she asked me to install some Neatmaster Ultrasonic Pest Repellers in her house, even though she hasn't noticed any "particular problems" with the spiders, ants, mosquitos, roaches, or rodents the device is designed to keep away.
The pest repellers plug into standard outlets and have 3 levels of sound-splaying settings, green, blue, and red for light, medium, and severe infestations respectively. Click through them using a button on the side of the Neatmaster device before settling on one. Probably not the red one.
Because the red one - holy sonic attack, Batman! This setting, rightly, is not recommended for installation in any space you plan to inhabit or walk by while in use. I turned it on inside a crawl space under my mama's stairs and was like, Arrrggghhh! Mine ears! Mine ears! And I could still hear it even after closing the door and walking 10 to 15 feet away. The ringing stayed for a couple of minutes after I turned it off too, and that was after less than 60 seconds of use.
But the green and blue settings - I left Mama's on the latter - were inaudible to me. I don't know if they'll terrorize pets, my mama doesn't have any, but if it somehow keeps her neighbor's fat cat, Willard, out of her yard, she'll probably consider it a prime Neatmaster Ultrasonic Pest Repeller selling point. Willard is one of her (many, many) nemeses.
For the record, Neatmaster says the ear-assaulting red setting is the only one audible to humans and household pets.
So far my mama hasn't reported any suspicious pest activity, and those who have tried the Neatmaster repellers have pretty good things to say about them. They're certainly worth a try, given they don't require the use of chemicals that would hurt way more than your, your kids', and your pets' ears. The ultrasonic method also gives the pests you want to rid yourself of a fair trade: stay away from this unpleasant noise, and I won't kill you.
