For a healthy niche holding plant species, insect life, even if there's *some baddies around feeding on the plant, Imho is a good thing.
The presence of a healthy thriving ecosystem around your plants actually helps in controlling pest populations counterintuitively. When your plants don't stand out like sore thumbs to the pest species, they spend more time moving from plant to plant, and less time housing themselves up.
A good example of this is how guerilla growers planting inside succession zones at the ended of forest lines or on the edges of a flood planes, and how rarely if ever do these grows suffer blanketed infestations of anything even if completely untreated, but you can almost *always find unwanted pests on these plants whenever you want, but rarely are they a grow altering problem. There's just too much other attractive vegetation around them. If you don't leave an exit ramp, nothing will take it. You have to exterminate it all instead
