Insects are causing problems
Bag worms and Japanese Beetles are causing problems
Japanese Beetle grubs feed on grass roots and adults feed on the foliage of over 300 species of plants. Bag worms can severely defoliate and kill evergreens. They also feed on fruit trees and ornamental trees and shrubs.
