Its that time of year again... They're coming in from the winter cold... I cant/wont use poison, because my cats sometimes get ahold of the mice... And the traps kinda freak me out when i hear them go off and the scurrying if it isnt killed right away... (but i can deal with that.. if need be.) I was wondering if those plug-in things worked?? or a waste of money and time? Personally, i think poison works best but i just cant risk it. If you think they work,... which brand do you use?? Thanks!
