How odd, Judi as I am also not finding it so effective. I still have lots left in the can I bought last year but am considering buying a new one to see if that would be better. I have discovered several baby scorpions in my living room and a centipede in the kitchen and think they are coming in under the front door which I spray round on a regular basis, even though it says it is effective for one year. The other morning I also found a wide trail of those tiny little ants making for 2 separate bowls of cat crunchies on opposite sides of the room.
