Not necessarily ... information provided by Fredo (though again we're never told what that is) might allow Roth's men to infiltrate the home and then the bedroom (or even rig something up from outside the bedroom) to open the drapes.
Which you correctly state would have to have been done while Kay 'dozed' off because she would not have gotten into bed with those drapes opened.
