Regarding copper wire and copper bands, I will reiterate what I stated before, then let it go. A state biologist presented in Puna in 2009 that he tested the efficacy of copper banding in preventing slugs and snails from crossing. He found in his lab that it did NOTHING to retard slugs and snails from crossing. They crossed right over it. There you have it.
( Edit: I just read in the CTAHR report mentioned earlier in this thread that slugs won't "generally" cross a copper band that is 3-4 inches wide.)
As to water catchment, rat lungworm infects humans who consume the nematodes that live inside the slugs/snails. The severity of the infection is partly due to how many nematodes are initially consumed because they do not reproduce inside the human body. A 5 micron filter and then uv should be enough to kill any that get that far. The nematodes don't live long outside the host either so they are not just swimming around in anyone's catchment tank.
(Edit: I just read that the infective stage of the nematode is when they are about 400 microns large. That is about the size of this period. So the filters will catch them. But good luck seeing that on a lettuce leaf.)
