Quick Answer: Yes, mice do eat grass, but it’s not their preferred food source. Think of it as a snack, not the main course.
Introduction: If you’ve noticed unusual damage to your lawn or are simply curious about mouse behavior, you might be wondering about their dietary habits. This guide explores the relationship between mice and grass, providing practical advice on preventing mouse-related lawn issues.
Why Do Mice Nibble on Grass?
Mice are opportunistic omnivores, which means they’ll eat a variety of foods depending on what’s available. While their ideal diet consists of seeds, grains, nuts, fruits, and insects, several factors might lead them to nibble on grass:
- Nutritional Supplementation: Young, tender grass shoots can provide mice with additional vitamins and minerals, acting as a sort of natural multivitamin.
- Digestive Aid: Similar to cats, mice may eat grass to help with digestion and to expel hairballs. The fiber in grass can aid in their digestive processes.
- Survival: During times of scarcity, especially in dry periods or when other food sources are limited, grass can become a vital source of sustenance and moisture. Think of it as their emergency rations.
- Thirst Quencher: Particularly in dry conditions, grass can provide a source of hydration for mice.
What Kind of Grass Do Mice Eat?
Mice aren’t particularly picky when it comes to grass species. They’re likely to munch on tender, young shoots of common lawn grasses like Kentucky Bluegrass, Ryegrass, or Fescue. They also enjoy grass seeds, which are nutrient-packed.

Is Grass Harmful to Mice?
Generally, grass itself isn’t harmful to mice. However, if your lawn is treated with pesticides or herbicides, the chemicals can be toxic. Always opt for pet-safe and environmentally-friendly lawn care products.
How to Prevent Mice from Eating Your Grass
Keeping mice away from your lawn involves a combination of strategies:
1. Eliminate Food Sources:
- Store Properly: Keep birdseed, pet food, and any other potential food source in airtight containers.

2. Seal Entry Points:
- Inspect and Seal: Check your home’s foundation, walls, and areas around pipes for cracks or gaps. Seal them with caulk, steel wool, or other appropriate materials.

3. Natural Deterrents:
- Plant Mint: Planting mint or peppermint around your garden can deter mice with their strong scent. Other repellent plants include lavender and catnip.

4. Traps and Baits:
- Humane Traps: If necessary, use humane traps to capture mice alive for release elsewhere.

Identifying Mouse Damage in Lawns
Mouse damage can appear as small, irregular patches of closely cropped grass, particularly around the base of plants. You may also notice shallow burrows or runways.

Regional Variations
Mouse species and their dietary habits can vary by region. Some mice might be more inclined to eat grass depending on available food sources and local climate conditions. Contact your local university extension office or a pest control professional for region-specific information.
Conclusion and Call to Action
While mice do occasionally eat grass, it’s typically a supplementary food source rather than their primary meal. By understanding their behavior and implementing preventative measures, you can protect your lawn and maintain a healthy ecosystem in your yard.
