slugs in greenhouse

Last night after seeing some slug slime on one of my pepper plants I decided to try a cunning plan, I dotted a few blue pellets here and there, some on the bench and some on the greenhouse floor, no more than 10 in total, just to see what happened.  This morning I was gobsmaked to find about 15 or so dead slugs, mostly on the floor around the edge of the greenhouse, one of them was massive so god knows where it was hiding  :blink:

I have nightly torchlight visits to my ghouse --- that's why
