I had mice invade my cottage during the winter.I called Amtech and they responded immediately and sent two of their employees to explain what they were doing to solve my problem.They worked quickly and returned weekly to check on the problem in no time the house was free of mice. Attach would call before my tech arrived and he would let me know the progress that was made.the tech was very professional,informative, and caring.I would recommend Amtech to those who have problems with wild life.
