Slugs in the house!!!
we tried intensive cleaning, removing skirting / kick boards, blocking holes all without success. Salt just seems wrong.
we never see them in the day so we started leaving a lamp on in the middle of the kitchen floor. In the evenings that followed we removed a few slugs that might have been in residence. Following that we have been slug free. Some articles suggest slugs move toward light to avoid predators so I may be wrong but while it works I will leave a light on.
