How long does it take to get rid of mice?

I have purchased but not yet recieved the device to use on mice. It is an electrial device that sends electrical pulses that distrube the mice from nesting and setting up shop. How long does it take before I should see a lack mice. Also they say I should see more activity? What do they mean by more activity. The mice now are not seen scurring around the house. Only seen by the droppings in my basement finished basement food cabinet.

If any one has any comforting words please respond.

listen kid just get a cat I have one and I havent had a mouse for a long time

Mice are a pest for sure. I feel for you. Mice require one thing to survive and thrive. FOOD!! If you take away their source of food whatever that may be do it. Clean the areas you've seen them in and put down mouse traps. Try to find out where they are coming from and seal the entrance way off. Be aware though that they only need a hole the size of a dime to get in. Look for signs, poop etc. A cat wouldn't hurt either.

Good luck.
