I do use slug pellets, albeit the ferrous sulphate ones which are organic and do not harm other wildlife such as birds (as opposed to the bright blue metaldehyde ones), and only sparingly.
I've given up putting fairly small seedings into my front garden, as the slugs hide underneath the large lavender hedge and come out at night - so look to see what might be hiding slugs. Also don't plant out so small.
And cultivate an allotment which is friendly to foes of slugs, such as thrushes.
I have no answer to the mozzies question, except for bug spray and long sleeved clothes!
