SUMMARY In trapping slugs, 1 part of 30% Sevin (carbaryl) (1‐naphthyl‐N‐methylcarbamate) to 40 parts of standard metaldehyde‐and‐bran mixture gave an improved catch over standard biscuits. The fungicides dazomet or zineb incorporated in biscuits repelled slugs. It was shown that the fall‐off in the attraction of metaldehyde and bran did not occur until 4 days after biscuit exposure, and that black glass plates placed over pelleted baits masked their effect, the same catch being obtained with one or with sixteen pellets. Even without glass plates there was evidence to suggest that the catch of Agriolimax reticulatus was similar with one or sixteen pellets. The implications of these results on control measures are discussed and it is recommended that metaldehyde sprays be used for epidemics, and the baits only as long‐term measures to keep down infestations already partly controlled.
