We get slugs in the kitchen, when we have the window open, I guess they just crawl in. I scoop them up and chuck them out, and then spend about half an hour washing my hands. Yuk.
I had a row years ago on the allotment, when the woman in the next plot saw me scattering slug pellets. She ranted and raved, but I made the point, no slug pellets, no French beans. And this is true. Some years, they attack tomatoes.
