1.	Eliminate breeding places: Practice sanitation in the garden by removing decaying matter and rubbish.
2.	Modify garden design: Eliminate plants that are known to be attractive to snails substituting less snail-attractive species.
3.	Isolate host plants: Locate plants that are attractive to snails to specific areas so other methods of control such as diatomaceous earth barriers can be utilized.
4.	Hand picking can be effective: When snails get up into plants, hand picking is often the only way to remove them.
5.	Install copper barriers: In some instances barriers of copper screening or copper strips can be used effectively to keep snails from certain areas. It is also reported that painting a liquid solution of copper sulfate on tree trunks, etc. will effectively repel snails.
6.	Use Sluggo: Sluggo is an organic alternative to metaldehyde baits that can be used safely around domestic animals. The active ingredient is iron phosphate which occurs naturally in the soil.

Instructions for using Sluggo, an organic snail and slug bait:

Even though Sluggo is an organic material, it is considered a pesticide and all necessary restrictions and precautions must be observed. The label lists all the information needed by the applicator for the safe use of this material and should be reviewed prior to each application. Appropriate personal protective equipment, including coveralls, boots, rubber gloves, and eye protection, must be used.

Hazards To Humans And Other Domestic Animals: Sluggo can cause eye irritation. Read and follow label instructions.
General information: The bait is attractive to snails and slugs and lures them away from their hiding places and plants. Ingestion, even in small amounts, will cause them to stop feeding, become less mobile, and begin to die within 3 to 6 days. Dead snails and slugs may not be visible as they often crawl away to secluded places to die. Plant protection will be observed by the decrease in plant damage.
How To Apply: The granules should be scattered on the ground around the plants to be protected. Apply bait evenly at about 1 pound per 1000 sq. feet (0.15oz., or about 1 level teaspoon per sq. yard) and reapply as bait is consumed or at least every 2 weeks. Do not place in piles. If ground is dry, wet it before spreading bait. The soil should be moist, but with little or no standing water.
When To Apply: Evening is the best time to apply the bait.
Where to apply: All likely areas of infestation should be treated, especially the perimeter of garden plots. These pests travel into plant areas from daytime refuges. Favorite areas include flower gardens, rockeries, hedges, citrus groves, ivy patches, and other ground covers where they obtain shelter by day.
