I saw some fleas on our dogs today so we are going to be cleaning the house and carpets tomorrow to hopefully get rid of them. I got some flea spray for carpets and furniture and was wondering how long the chins should be out of the room after I spray it? I sprayed some in the hall and it the smell goes away after a minute. I can bring their cage out of the room so it won't get on their stuff. I can also open the windows to air the room.
