How big are the holes? Does the surrounding leaf appear to be diseased or
damaged?
Sometimes Ladybug larvae attach themselves to iris leaves to pupate. When the
adult ladybug emerges, a clean, ladybug-size hole is left in the leaf. I
discovered this because I'm very protective of my ladybugs at all stages of
their development. I've concluded that a few leaf holes are a small price to
pay for the pest control they provide.
So I advise against spraying unless you've identified a pest.
