Sonic wave bug deterrent?

Question

do those plug-in, sonic-wave rodent and bug machines work? Sunbeam makes one; I'm not sure if there are others. My office has the reputation of having a spider and waterbug problem, and I've seen roaches occasionally. I'd like a non-chemical way to deter them. Has anyone had success with these machines? Are they safe around dogs and cats? Thanks.

Answer 1

my mom got one when we had mice...I never saw any mice and the cats and dogs did't freak..never affected the spiders, though. don't know about water bugs.
