Mice are opportunistic omnivores, meaning they'll eat almost anything they can get their paws on. And yes, mice absolutely do eat birdseed. This makes bird feeders a particularly attractive food source for them, often leading to unwanted guests in your garden or backyard. This article explores why mice are drawn to birdseed, the potential problems this can cause, and how to deter them.
Why Do Mice Eat Bird Seed?
Birdseed provides mice with a readily available source of carbohydrates, fats, and proteins. Different types of birdseed offer varying nutritional benefits to mice:
- Sunflower seeds: High in fat and calories, these are a particular favorite.
- Nyjer (thistle) seeds: These small seeds are easier for mice to access and consume than larger seeds.
- Milo: Although less nutritious than other seeds, mice will consume it if other options are scarce.
Essentially, birdseed provides mice with an easy, energy-rich meal, especially during colder months when other food sources might be limited.
What Problems Can Mice Cause Around Bird Feeders?
The presence of mice around bird feeders presents several issues:
- Disease transmission: Mice can carry diseases that can be harmful to both birds and humans. Salmonella and hantavirus are examples of diseases they can transmit.
- Competition for food: Mice will readily compete with birds for the seed, potentially reducing the food available for your feathered friends.
- Property damage: Mice can gnaw on wooden feeders, garden furniture, and even the siding of your house.
- Nesting: Mice may build nests within or near the bird feeder, potentially attracting more mice and creating a larger infestation.
What Kind of Bird Seed Do Mice Prefer?
While mice will eat almost any type of birdseed, they tend to show a preference for seeds that are high in fat and calories, and those that are easier to handle. Sunflower seeds are a top choice, followed by smaller seeds like nyjer. However, they won't hesitate to consume other types of seed if readily available.
How Can I Keep Mice Away From My Bird Feeder?
Preventing mice from accessing your bird feeders requires a multi-pronged approach:
- Choose the right feeder: Opt for feeders that are difficult for mice to climb onto or access. Metal feeders are generally preferable to plastic ones as they're less susceptible to gnawing. Consider feeders with cages or baffles to deter rodents.
- Regular cleaning: Regularly clean up spilled seed and remove any droppings to eliminate attractive food sources and nesting materials.
- Secure the area: Eliminate potential entry points to your yard or garden, sealing any cracks or holes in walls or fences.
- Use deterrents: Commercial rodent repellents can be used, though their effectiveness varies.
- Consider alternative feeding methods: Ground feeding attracts mice, so choose hanging feeders instead. Using feeders with weight-activated mechanisms which close when the birds are not feeding can also help.
Are There Other Animals That Eat Bird Seed?
Yes, many other animals, besides mice, will eat birdseed. These include squirrels, rats, chipmunks, and various birds. Strategies to deter mice often overlap with strategies to deter these other animals.
By understanding why mice are attracted to birdseed and implementing effective preventative measures, you can provide a safer and more enjoyable feeding experience for your birds while minimizing the risk of a rodent infestation. Remember, a clean and well-maintained feeding area is key to keeping unwanted guests away.
