You
will find red spots every week but you will not care much. It
won't disturb you. When you are bitten and as soon as the red
spot fades away, a new one will appear which means that you will
be beaten occasionally. Still in your mattress you will be able
to find bedbugs. When you find and kill them, only for one or
two days you will be sleeping well.
Then
you can call as "MODERATE"
