I just put a sharp gardening knife through them!
Crushed and thrown onto the path for the birds.
Slugs in the "Slug Jar" filled with salt water and then down the drain. Unless they drown in the beer traps first. But still down the drain in the end.
I just chuck them into the middle of the lawn all in one pile - the birds soon notice.
The lack of thrushes is believed to be down to years and years of slug pellet use before the ferrous type was introduced.
I found this gardener's blog page, who attended a Kingston Mauward lecture on slugs and snails then shares notes taken; aerobatics didn't seem to be on the college syllabus on solutions :0
I've noticed that thrushes won't eat snails that have eaten slug pellets. I regularly find dead thrushes in cold winters and snowy periods.
I don't use slug pellets, but wonder how far slugs can actually travel, ie if they go next door and eat slug pellets how quickly does it kill them, could they get to our garden and then by me killing them with a fork and giving them the birds cause a problem?
Science has recently proved that snails have a homing instinct, we knew this when we were kids back in the 50's we painted them different colours and then took them out of our garden and down the road and then released them. Each day we would go to the spot where we had collected them to see if they were back and whose snail had won. We had them come back from dissidence's of over half a mile. They were sometimes back within a few days, we discovered that they returned quickest in warm damp weather. I which I had had the research grant to do the latest scientific discovery!
I chuck mine in the green recycling bin - destined for an awful end I'm afraid.
I DO feel guilty as I do it, and I have to shut the lid pretty damned quick to avoid all the previously chucked slugs getting out.
I doubt they actually get tipped into the waste cart, being so tenacious, so I guess they die a happy death munching away at all my weeds in the bin.
Currently, I chuck mine into the busy road at front. At University, in the rented garden, I would gather them up and then pour lye on them. In retrospect, pretty dangerous and I have no idea what that might have done to the soil, but I poured it on morning glories that were taking over everything.
I also had two large puffer fish in a tank and they loved snails. It was great because they needed the shells to keep their teeth from getting too long. Made for a nasty filter however.
