Mice are curious little creatures and can be caught if trap placement is strategic. Problem is that as curious as they are they are just as smart. I've seen where I've put glue boards down flat against the wall can came back a week later to find that the mice actually built a bridge of debris across the gluetrap so they could cross the trap without getting stuck in the glue!!
If you are faced with a mouse problem then my advice would be to integrate your approach. Most people go out and buy few snap traps, slap a glob of cheese on the trigger and wait.
First off. Look to see where the activity is heaviest. If you are finding lots of dropping under the sink the thing to do would be to clear out the underneath of the sink and set the snap traps with just a smear of peanut butter or a small piece of cheese. Make the mouse work at getting the food and your success rate will increase. Also use lots of traps. Don't just buy two or three, buy 10 or them putting 2 traps per side and 2 in the middle. Some traps bait with cheese and others with peanut butter. If they are getting into candy then bait with chocolate. Some folks will attach cotton to the trigger. Mice use this for nesting material and will get caught struggling to free the cotton from the trigger. If you decide to throw in some gluebaords into the mix I would not advise putting anything to attract the mouse to them. Some people will plop a glob of peanut butter in the center of the trap hoping to attract the mouse to get stuck. The oils in the peanut butter spreads into the glue rendering the trap useless.
If the mouse is noticed each night scurrying back and forth along a certain wall then put your traps here ( be generous) and you'll most likely catch him. Mice tend to travel the same route each night. IF you catch one then don't think you've won. There may be several to deal with so keep the traps down. If you haven't caught anything in a few days then place them in different areas. Even if you move the trap a few inches to the right from where it is. This will help in catching them.
