All pets should be excluded from the room when R.I.P. Fleas Extra is sprayed. Immediately after spraying, open windows and ventilate the room for at least 1 hour. Make sure all spray mist has settled and all surfaces are dry before allowing any pets to re-enter. After this time, dogs and cats should be allowed to access all areas of the house as this will encourage pupae to hatch, shortening the pupal window and enabling the infestation to be controlled more rapidly.
