No one wants tiny home invaders like insects and rodents sneaking around the house. The question is how to get rid of and prevent their infestations. For the tender-hearted and the squeamish, kill traps won't fit the bill. That's what makes the uHome an attractive alternative. The humane device emits powerful, penetrating ultrasonic waves, which, instead of killing its targets, simply drives them away. The sound waves are not audible to the human ear, but for for spiders, roaches, ants, mice, and more, the ultra-high-pitched noise makes your home a decidedly inhospitable place. If you're a pet owner, however, take care. Household pets such as cats, hamsters, and guinea pigs may be sensitive to the uHome's noise, but dogs don't mind it. Available on Amazon; $75 for set of four.
