Slug Bait (Metaldehyde)

• 1). Purchase a metaldehyde-based slug bait from a garden supply store or home improvement store. Read the label carefully to make sure the slug bait contains the chemical metaldehyde, which is extremely effective against slugs. Slugs are not bothered by many other insecticides, so it is important to use metaldehyde. Metaldehyde is normally available in liquid form and pellets or flakes.
  
  
• 2). Wait to use the metaldehyde bait until soil conditions are dry. Applying the metaldehyde to the soil while it is wet can result in the chemical being diluted too much to effectively kill the slug.
  
  
• 3). Apply the metaldehyde slug bait in areas of heavy slug activity. Use the bait where slugs are eating your plants, or in the soil where they are gaining access to your home. Spread 10 or more drops or pellets per square yard of soil. Keep pets and children away from the area after baiting.
  
  

Ammonia

• 1). Fill a bowl or container with one part ammonia and 10 parts tap water.
  
  
• 2). Pour the ammonia and water mixture into a empty spray bottle. Swirl the mixture around to thoroughly combine the ingredients.
  
  
• 3). Spray the ammonia mixture directly onto any slugs you see in your garden or by your home. Look for the slugs in the evening, after the sun goes down, which is their prime feeding time. Avoid spraying large amounts of ammonia on your plants.
  
  

Sodium Chloride (Table Salt)

• 1). Fill a shaker with regular table salt (sodium chloride).
  
  
• 2). Shake the table salt directly onto the slugs to kill them. Avoid using large amounts of salt on or around your plants, as the salt can hurt them.
  
  
• 3). Pour a line of salt to form a barrier between the slugs and areas of your garden or home. Apply the salt in a solid line that prohibits slugs form passing through it. Use this method only on pavement, concrete, bricks or wood. Do not pour large amounts of salt directly onto the soil, where it can contaminate the soil and kill your plants.
