Beetles damage ash trees, and how to save ash trees

1 banning transportation of ash trees, which will take beetle’s nests to other areas

1 they cannot prohibit private companies that cut down ash trees to be firewood

2 drilling holes on the ash trees to inject a chemical pesticide that make beetles leave away ash trees

2 drilling too much holes will damage ash trees. The cycle of injecting a pesticide is two years.

3 planting trap trees that beetles like to lay their egges on

3 trap trees are beetles’ food, which will increase the population of beetles and hurt more ash trees.
