At the end of last season I made some raised beds,
sieved soil, stable waste and farm yard manure all
mixed.
This was covered with old carpet to stop any weed
growth.

Today I uncovered and loosened the soil and found a lot of Centipedes and
millipedes.

Now for my questions.

1 Do they do any harm ?

Millipedes mostly eat dead and decaying vegetation, but can eat small
seedlings and cause further damage to slug-damaged corms, tubers, bulbs and
seeds

Centipedes are insectivorous - so are often considered to be helpful to
gardeners
