When we moved here I kept getting bites on my ankels, then we bought our lab puuppy Islay and as she came into our lounge she yellped and ran out,,,,we bought flea stuff (we had no cats) but we still got bitten so I put a trap to find what was happening, a bowl of water with a light over the top so the fleas jump up to the light and land in the bowl of water, that way we found out they were cat fleas, we got the pest man in and none at all since, it was only our lounge but funny how long the eggs stayed viable in there, poor fleas must have been soooo hungry. We just use front line for the dogs but its ticks I get fed up with, although I think front line keeps them at bay too...ticks are horrid things!!!
