In years when food is scarce for squirrels (such as last year when the maple trees did not produce many seeds due to a late frost), they can resort to eating bark to meet their nutritional needs. If this is happening, we recommend offering an alternative food and water source, such as nuts and seeds, to deter them from stripping the bark. Stripping bark can expose the xylem of the tree, leaving it susceptible to insects and diseases. They can also potentially girdle a tree and cause long term damage.
Research indicates that bark stripping has a higher occurrence following a "mast year" where trees produce a bumper crop of fruits and seeds, which may correlate with a higher population of juvenile squirrels. Here is an excellent article from Ohio State University about bark stripping.

Bagworms. Everyone’s favorite little defoliator, right? These clever moths begin life as tiny caterpillars and use the foliage of trees and shrubs to protect themselves so they can mate and create even more bagworms. They can be extremely destructive, and their cone-shaped cases oftentimes go unnoticed as "pinecones" or some other doo-dads that almost pass for something that belongs on the tree!
Can bagworms kill my trees and shrubs?
YES - Bagworms can disfigure or even kill evergreens in a hurry as they feed on needles. If you have a minor infestation of bagworms, pick off the cases and throw them away in a sealed grocery bag, place in a bucket of soapy water, or burn them if that gives you satisfaction. If your trees have more than a few however, give us a call so we can perform properly timed insecticide sprays. Remember, every case can have 300-1000 eggs, so you don’t want the population exploding from one year to the next!
How does Arbor Aesthetics manage bagworm infestations?
Arbor Aesthetics offers a two-time foliar spray treatment of either Permethrin or Bifenthrin insecticide while the larvae are actively feeding on your trees and shrubs. We closely monitor bagworm larvae activity so the timing of the treatments is most effective. We recommend repeating this treatment annually for at least 2-3 years before re-evaluating for control.
