Hopefully it doesn't spread.. there are things you can put under the bed stands that will keep them trapped if they try to escape but there are other ways of them getting off of the bed. Also, whatever you brought them in with (if you brought them in that is).. maybe a suitcase.. they may already be in other areas of the house. Empty drawers, take all your clothes to the dry cleaner, take pics off your walls and wipe them down (there could be eggs that you can't see).. Good luck bro - let me know how it goes.
