We have to clean and vacuum better the house everywhere. Hubby has done nothing about any of the lice infestation problem. The vacuum cleaner has been blocked with a sock for a week so we never vacuumed: the dogs keep getting reinfested in the environment! With the first day of sunlight in a week i stuck the dog bed outside on the deck. After much thought, in the plastic bag it goes for 6 weeks in the shed after I will have sprayed it tomorrow.
