For 2 years now my Yarrow has only produced lots of green growth but no flowers to speak of. I have sprayed it with a bug spray but still I cannot see any flowers developing. I bought it 3 years ago and put it in an island bed. It gets sun most of the day. Can you help?

Two reasons that would cause this is too much fertilizer & not enough sun.
Yarrow thrives in full sun and very well-drained soil. They like hot, dry conditions and low soil fertility, but won't tolerate wet soils which promote powdery mildew. It's a little early to expect blooms. As Landgirl mentioned, they are late bloomers.

Achilleas don't usually suffer from pests, did you see any before you sprayed? They are quite late to flower, mine are just starting to produce buds now.
