SUMMARY 0.025% endrin and 0.05% Rogor (dimethoate), when incorporated in standard metaldehyde and bran slug baits did not increase the catch of slugs. Both insecticides in bran biscuits acted as repellents. The addition of 1 part of 50% Sevin (I‐naphthyl‐ N ‐methylcarbamate) to 40 parts of the standard metaldehyde and bran mixture improved the catch by 15%. Arion hortensis did not appear to be attracted to metaldehyde to the same extent as Agriolimax reticulatus and Milax budapestensis and the latter species responded more when the nights were warm. Meteorological observations suggest that in the autumn and winter months more slugs are trapped when the night air temperature and the morning relative humidity are high. The age of the biscuits, the grass minimum temperature and the mean night air temperature accounted for 70% of the variance of the catch of metaldehyde biscuits.
