Thanks for reference.

Fleas love the shady areas of your lawn, so hit those areas extra hard.

Also, vacum the house like its the national pass time. Including the couch cushions & anywhere else the dog lays/sleeps etc. Replace or empty the bag/dirt catcher early and often.

In fact, go buy a new vaccum. A big one. One with lots of power, tell your wife that she isn't doing it right...

We will need pictures of you vaccuming the house......and your wife......
