We're so happy with Bulwark and have used them for two years now. (This is after being treated poorly by at least two other companies prior to that.) They always come when scheduled, the technicians are friendly...and they stand behind their work. If you have a service and at ANY time see insects before the next scheduled appointment, they'll come right out an spray again - for FREE. You can't go wrong and I wouldn't hesitate to recommend them to anyone.
