1st yr trying the Mosquito Treatment. 1st couple of treatments were fine. From then on, a date would be scheduled for a treatment and without notice, the date and time would be changed. Had conversation with District Mgr. But the last treatment was also switched. At that point I cancelled the contract. It seemed to me that because our yard was small it didn't matter when the treatment was scheduled. Would like to try it again in the Spring, hopefully with better results.
