This is an extremely broad question - the term "insects" covers a wide range of species, and the term "harm" is very vague.
In general, insects that are living in their native habitat don't harm the environment - they are part of the ecologic system and are both controlled by predators and control their food sources (plant pollen, other insects, etc). Native insects sometimes harm humans, such as mosquitoes biting humans and infecting them with malaria or dengue fever. However, this is normal for that environment.
Insects that are invasive into other environments tend to cause a lot of harm - there are no predators that can control them, and once established these populations tend to outcompete the native insect populations. Invasive insects can also harm humans, although the primary issue tends to be environmental.
