When we treat a house for unwanted pests we put a lot into the initial treatment often taking a number of hours to complete that process. Then we perform regular service at intervals to help keep the pests away. When you cancel the program you just might let the pests get restarted and entrenched again. That would require us to re-do the initial service to rid the home of the pests again. So, unless you reinstate your standing with A.E.P.I. quite quickly we may have to do the initial treatment over and we would have to charge you for that.
