Worms are good, do not worry about them. Carrot fly may be controlled by
planting something with a strong smell next to or around the carrots in
order to confuse them. EG Onions, chives. Or if you use filtered or grind
your own coffee spread the dregs between the rows. This may be too late for
next year but it will be worth trying next.

I recently built my wife a raised kitchen garden, which is very simply a
box
on legs, 2ft.6ins from the ground, so that she can grow some salad crops
without needing to bend. Firstly I have a problem with both carrot fly and
flea beetle,how do I deal with them and do I need to change all the
compost
or can I treat it? Secondly, not a problem but a mystery, I have a lot of
worms in the compost. Now bearing in mind the height of the box, how on
earth did the worms get there, as there is nothing but compost straight
out
of the bags in the garden?
