Don't use total release aeros. Get the aeros that you can hold upside-down and direct the spray. Thoroughly vacuum entire floor. Wash all bedding, pet bedding. Spray under all furniture, under all removable cushions, in all closet floors, under throw/removable rugs.

If cottage has floor vents, open them up, clean them out (fill up with pet hair, dander) and treat into. Clean under stove, fridge-again much pet hair/dander and spray same. It's hard work.

Make sure that you use a flea aero that has a "growth regulator" in it. It will be Methoprene, usually. Label may say something like egg stoppers, flea birth control, kills larvae, etc.
