After a very bad experience with a well-known national arborist company whose management has deteriorated badly, we are extremely pleased with Birch Fumigators. Due to the severe aphid problem this year we required two applications several weeks apart so we couldn't take advantage of Birch's free 2nd application within 1 week. However, without us asking, they reduced the second service call by $25 and we really appreciated it. So, the first application cost $130 and the second was $105. They are a family run business since 1900 (!!!) and we are extremely pleased with their service!
