I guess if you get organic - animal friendly pellets then that is organic...and if you aren't using them around your veg anyhow then I guess it doesn't matter.
The soapy water one has been talked about before. I don't believe the experts mean washing up liquid when they say soft soap, they actually mean horticultural soft soap, which as I understand it, is perfectly organic.
Me, I find my boot is an organic way of dealing with slugs and snails and my fingers squish the aphids, organically friendly, but a bit yuck!
