We found several ants in the kitchen area last month. Within 2 hours of the initial call to Cain Pest Control, someone was here to spray the kitchen area which has been free of ants ever since. We called yesterday when we found some ants in our bedroom and the very next day, someone came to spray the entire home (including the exterior). No questions asked. The 1 year guarantee worked for us and customer care has been excellent. We are very pleased with the results.
