Here is an example of what bag worms can do to a leyland cypress tree in very short order. Bag worms strip the needles from the tree to make their small pods. As more worms infest the tree, further damage is done.. Shrub Doctor noticed this damage as he was driving along the road. As is often the case, the home owner may not notice the damage until it has advanced to a serious level. Mark successfully treated the infestation using a nicotine based product containing the active ingredient bifenthren. The insect controls used by Shrub Doctor are very safe when used around pets and humans, and carry a “caution” rating. Insecticides carrying a caution label are the safest products to use in your landscape.
