Are Blueberries Bad for Snails?

When it comes to gardening, enthusiasts face a never-ending battle against the persistent pests that threaten to devour their hard-earned bounty. Snails, those slow-moving gastropods, often find themselves at the center of this botanical battleground. As we strive to protect our precious plants, it’s only natural to wonder: are blueberries bad for snails?

Blueberries are not bad for snails – they are rich in vitamins, antioxidants, and other nutrients. However, feed them in moderation, as snails have a diverse diet, and consuming a specialized diet of blueberries may not provide all the necessary nutrients for optimal health.

This article delves into the effects of feeding snails with blueberries while also providing additional information on nutrition options that snail farmers, aquarists, and hobbyists can adopt.

The Special, Destructive Nature of Garden Snails

Unlike many other snail species, garden snails are uniquely herbivorous. When people complain about the destructive nature of snails, it’s almost always the garden snails they’re referring to.

Found on doorposts, flower gardens, fruit farms, and vegetable gardens, these snails can wreak havoc on your cherished plants.

Garden snails are notorious for their appetites. Their herbivorous nature leads them to the following destructive path:

  • Create unsightly holes in the broad leaves of collard greens.
  • Mercilessly sever the buds of fruit trees.
  • Rasp against tree bark.
  • Ruthlessly chop off your beautiful flowers.

Given that people plant gardens to enjoy the bountiful crops they yield, the presence of snails in these habitats is highly undesirable.

Can Garden Snails Eat Blueberries?

Garden snails have been known to munch on blueberries found on trees in the garden. However, blueberries are not their top food choice when they are busy ravaging the lush greens. Garden snails are less likely to opt for blueberries if other food options are available.

Other factors may deter snails from approaching the blueberry tree and its fruits. Many farmers utilize pesticides and other chemicals to boost their garden’s productivity or protect their precious crops from unwanted invaders.

Interestingly, garden snails possess an instinctive ability to detect poisonous foods, particularly those tainted with pesticides. Consequently, they steer clear of blueberries when the fruits contain toxic chemicals.

Feeding Blueberries to Your Pet Snail

While garden snails have the freedom to choose their own food, pet snails rely on their keepers for sustenance. Fortunately, many snail enthusiasts are dedicated to ensuring the well-being of their slimy companions, which includes providing them with a proper diet.

Feeding blueberries to your pet snail is possible, but it requires caution. Pet snails can be either aquatic or land-dwelling. Some people prefer keeping snails in aquariums alongside fish. In contrast, others create suitable habitats for their pet snails within their living environments.

Regardless of the setup, caring for pet snails is a labor of love. When it comes to snails in aquariums, feeding requires extra care since the food is placed in the water. Unlike in a dry environment, food can spoil faster when it gets soaked.

Fruits like blueberries can deteriorate quickly when left in water for extended periods. Therefore, it’s important to determine how much your snail consumes in a day and provide only the amount of food they can finish within twenty-four hours.

Any uneaten blueberries should be promptly removed from the tank to prevent rotting and maintain a clean habitat for the snail.

Feeding your pet snails blueberries offers significant nutritional benefits. Consider the following points: 

  • Blueberries are antioxidants, which means they can help delay or prevent cell damage in snails by neutralizing harmful molecules in their bodies.
  • Rich in Vitamin C, blueberries contribute to the protection and health of the snail’s body cells.
  • The dietary fiber content in blueberries promotes normal bowel movements and maintains bowel health in snails.
  • Blueberries are a rich source of minerals such as calcium, phosphorus, zinc, manganese, and iron, each playing a vital role in enhancing the overall health of snails.
  • Blueberries are an excellent dietary supplement for snails, providing a refreshing break from their regular diet and adding variety to their meals.

There is no doubt that blueberries offer significant nutritional benefits for snails. Still, it’s important to exercise caution due to the following factors: 

  • The risk of overfeeding: Snails may be tempted to consume more blueberries than they need due to their sweet taste, leading to constipation issues. Provide them with an appropriate portion size to maintain their digestive health. 
  • The risk of poisoning: Opt for organic blueberries grown without the use of harmful chemicals and pesticides. This ensures that the blueberries you offer to your snails are safe for consumption and won’t pose any toxic risks. 
  • Cutting the right size: Snails don’t have teeth; instead, they possess a radula, which they use to rasp on food. Cut blueberries into small pieces that are easy for snails to consume, allowing them to effectively rasp and feed on the fruit.

What Foods Are a Must-Have for Snails?

If you are keeping snails in captivity, provide them with calcium-rich foods. Calcium is the most vital nutrient for snails, as it is crucial in ensuring proper body function.

Here are some key reasons why calcium is essential for snails: 

  • Fluid regulation: Snails require ample fluids in their bodies to maintain moisture and produce sufficient slime, which aids in their movement. 
  • Shell formation, growth, and development: Calcium is instrumental in the growth and development of snail shells. Without an adequate supply of calcium, the shells can become brittle and prone to damage. 
  • Egg-laying: Snails need calcium to prepare for reproduction, especially while laying eggs. Calcium is vital for the formation of strong and healthy eggs.

Garden snails have a distinct advantage as they can find foods naturally rich in calcium as part of their daily activities. They will feed on calcium-rich plants and use rock particles, discarded bones, and eggshells to ensure they receive an adequate dose of calcium.

For snails living in an aquarium, their calcium intake can be supplemented through plant foods and other fruits that are high in calcium. However, it is important to provide additional sources of calcium to ensure they receive a sufficient supply.

Supplemental calcium can be in the form of:

  • Cuttlebones
  • Crushed eggshells
  • Natural rocks
  • Limestone
  • Powdered calcium

When it comes to feeding snails, there are no strict rules on how much food they need. It is essential, however, to exercise caution in selecting their food, as certain items can be harmful to snails.

To determine the appropriate amount of food, observe your snail’s eating habits daily and adjust the quantity accordingly. If your snail consumes all the food provided, it may indicate that more food is needed. Pay close attention to their eating patterns and ensure they are fully satisfied with the amount of food they receive.


Snails remain one of the easiest animals to keep as pets, and they are fortunate to have a wide range of food options. Their diet includes:

  • Natural plants
  • Meat products like worms and insects
  • Decaying plants and animals

Blueberries, in particular, are a beneficial fruit for snails due to their mineral content and dietary fiber, contributing to their bowel health and overall well-being.

Additionally, blueberries act as antioxidants, aiding in neutralizing any potential harmful effects from accidental ingestion of other food particles.
