Fleas are a real pest.
The Cat Flea is the one that bites us Humans. So, in order to solve problem, we would apply a residual insecticide to the appropriate floor areas and upholstery. A residual is needed to kill the young emerging from the eggs left in the carpet etc.
It may take several days for the problem to disappear, especially if the premises is vacant...for the fleas react to vibration caused by human movement...thus often seen jumping when one enters a room.
Our charges are $140-180+gst for the treatment of an average sized house.
