We have been using Bryant Pest Control for a couple of years.  They are always on time, neat and professional. The phone person who calls the day before they spray is always in an upbeat mode and a pleasure to talk to.  Like most people, we are not fond of bugs.  Accordingly we have Bryant Pest Control out once a month, year round.  Never an issue and rarely do we see any bugs.  If you are not having them spray every 30 days, you might wish to consider that program.  To us it is money well spent.
