do u need to spray kitchen and bathroom floors? - only round the edges or joins
do u have to spray laminate floors ? - hard floors with no gaps shouldn't need spraying
or is it just carpets and soft furnishings ? - yes + any other cracks & crevaces
do u spray skirting boards? - yes - where the carpet & skirting join is a popular meeting place for fleas
does the animal have to be away from the room while its drying ? - yes - it will tell you on the can how long. It will tell you to air the room out too.
is one can enough fo a small house ??? - depends on the make and size of can - the can the vet gave me says it does an "average 3 bed house" (I had to get 2)
does it kill and prevent fleas ???. The better ones kill fleas and have a hormone stunter in that stops the larvae & eggs developing (eggs can't hatch)
do u spray animals bedding or just wash it ? - a hot wash should kill anything (60 degrees) most pet bedding says wash at 30 but I always chance it and wash at 60
I'm sure you know this but the can says never spray onto an animal.
