Some people like to use saucers of beer to attract the snails. Dispose of the pests after they've fallen in. I'm always hesitant to use product names in this column because a number of products on the market can help solve various gardening problems. But there is a lot of talk about Texas Pure Industries' red cedar products, and sometimes talk warrants a reference to a particular brand. See today's Lazy Gardener for other comments on this product.
Persistence is the answer in trying to control snails.
As it gets hotter and drier, there will be some relief. Wet springs are the worst, and many gardeners reach for one of the baits and sprinkle it around to save their plants. Cutworms sleep by day and work by night. There are cutworm baits that can be sprinkled around the base of plants you wish to protect. You can slip paper or plastic cups around seedlings to keep the worms away until your plants can put on some size.
