You must do the following before a flea treatment: Pick up and remove all electrical equipment and trailing electric cables from floor surfaces that require a treatment. Vacuum all floor surfaces and empty contents of vacuum. Pick up and remove all personal items, clothing, toys, books and any other possessions off floor surfaces. This includes underneath beds and any carpeted walk in wardrobes. If you have any pet cats or dogs they must have already been treated with a professional flea treatment from a veterinary practice. Declutter and move all items of furniture away from walls. You will have to vacate the property for approximately 4 hours after the treatment or until dry. All pets must be removed from the property during and after the treatment until treated floor surfaces are completely dry.
