We contacted Kaiser Tree Preservation Co. in April 2013 to have our yard’s perimeter treated for ticks after four members of our family contracted Lyme Disease during the summer of 2012. Kaiser Tree is an excellent company across the board–punctual, professional, and competent in every service they offer. After being impressed with their tree service (both removal and planting), we decided to use them for tick spraying. We noticed immediate improvement in tick activity in our immediate yard. They spray the perimeter of our yard very thoroughly 4 times through the active tick season and always call a day or so ahead prior to their actual spraying. We will continue to use this company for our tree and yard services, and most definitely, future tick and mosquito control. We give our highest recommendation and feel fortunate to be able to rely on their expertise.
