Brewer Russel is a good mid-priced exterminator who responds quickly. And they do a great job.
There are a few smaller companies that are cheaper, but you never know if they'll go out of business and not be able to keep their guarantee.
I'd recomend Brewer Russel for any pest elimination problems, or for termite certificates when buying a house... they've been known to bend a few rules for you now and again.
