It wouldn't be a bad idea to do the yard also.  Where I lived before I had
carpenter ants infest the house and had to spray outside weekly to keep a
barrier around the house to avoid re-infestation.  The added bonus was that
the product I used also killed fleas.  I just made sure that on the days
that I sprayed that my dogs weren't out playing in the yard.

I hope so too.  Wasn't it the killing of cats (for being witches' familiars)
that *caused* the plague in the middle ages??!  Not enough cats let all
those rats with plague-carrying fleas spread throughout all of Europe
unchecked!
