Trap check
From MHWiki
These are random checks of your mouse trap and although they may not occur hourly, you will average about 24 each day.
Reporting problems
If you notice that your quantity of checks is way off, then add your concerns to the most current trap-check related thread under the Tech Support heading of the discussion boards. Make sure to search for older posts that are similar in topic, as your problem may have already been answered, thus a new post would be rendered redundant.
