Open the windows and cover the area with some bicarbonate of soda or if you don't have any to hand, talcum powder.Put a bit of kitchen paper on top of the powder and then shake a few drops of tea tree oil or any nice smelling essential oil onto the paper and then leave it over night or for a few hours and then remove the paper and vacuum the powder up.
Or make up a solution of white vinegar and water ..spray this onto the area let it dry and then vacuum . I know its a vinegar smell but it's better than sick !!
