Annihilate means to destroy something completely, reducing it to nothing; think nil in annihilate meaning nothing.
Decimate is often used less literally in modern language to describe substantial but not complete destruction; annihilate is absolute.
Decimate might imply a significant loss or reduction, but there's always something left.
Use decimate for large-scale harm but incomplete devastation, and annihilate for total obliteration.
