Your flea control expert can help you prepare for a treatment, but you'll want to ensure that all food items, dishes, toothbrushes, and other items you put in your mouth are removed from the house or stored in a closed cabinet. It may help to vacuum prior to treatment, as its vibrations can encourage pupae to emerge. If you have a special case, such as an aquarium you can't easily move, seal it and turn off the air pump. Your exterminator can review other options and directions with you.
