After using Colonial Pest Control one time for mice (which they did a wonderful job; never saw one again), we decided to sign up for the quarterly program. We just had our first visit and the technician was wonderful, friendly, knowledgeable, and explained everything he would be doing for ants, wasps, hornets, etc. Since he has left days ago, we have not seen a single ant or wasp, etc. I would (will) recommend them to all my friends and family!
