As far as I know, It is not harmful to cats if used according to label directions, and allowed to fully dry, etc.
Tick control usually begins outdoors, with a thorough treatment of the outside outdoor areas, lawn, tree bases, shrubs, etc, with a product such as Bifen IT. Treatment of outdoor areas and also treatment of animals are the first lines of defense before anything should be done inside. Ticks can be a problem on both cats and dogs.
So the bottom line is that only spraying the bedroom may not do anything. I complete program is probably going to be what it takes to get control. Then again, you can try.
