7 Things how to make a mealworm feeder reveal bird feeder secrets

Constructing a specialized apparatus for dispensing insect larvae is a straightforward process that provides a high-protein food source for wild birds.

This type of bird feeder is specifically designed to hold and present small, wriggling invertebrates in a way that is accessible to birds but prevents the food from escaping or spoiling.

For instance, a simple, effective version can be a small, shallow glass dish with smooth sides placed in a protected area, while a more elaborate example might involve a covered hanging container with small openings for birds to access the contents.

The primary goal of such a device is to deliver a specific type of nutrition efficiently, attracting insect-eating species that might not visit traditional seed feeders.

how to make a mealworm feeder

Creating a dedicated feeding station for mealworms is an excellent way to attract a diverse range of bird species, particularly bluebirds, robins, and wrens, which favor insects over seeds.

Unlike standard seed feeders, these devices require specific features to contain the live or dried larvae while allowing birds easy access.

The construction process can range from incredibly simple modifications of household items to more involved woodworking projects, catering to various skill levels and available resources.

A well-designed feeder not only provides essential nutrients for birds, especially during nesting season, but also offers a fascinating opportunity to observe avian behavior up close.

The initial step in any project is gathering the appropriate materials, which will depend on the chosen design.

For a basic dish-style feeder, all that is needed is a small, shallow glass or ceramic bowl with smooth, vertical sides approximately one to two inches high.

For a hanging feeder, a small plastic bottle, a clean jar, or a purpose-built wooden container can be used, along with wire or durable cord for suspension.

Essential tools might include a drill for creating drainage holes and access ports, sandpaper for smoothing rough edges, and non-toxic, waterproof glue or screws for assembly.

One of the simplest and most effective designs involves repurposing a small glass or ceramic dish. Select a container with slick, steep sides to prevent live mealworms from crawling out and escaping.

This dish can be placed directly on a deck railing, a flat-topped stump, or within a larger platform feeder to protect it from the elements.

To enhance its effectiveness, ensure the location is visible to birds but offers nearby cover, such as shrubs or trees, allowing them to feel secure while feeding.

This method requires no assembly and can be implemented immediately, making it a perfect starting point.

For a more weather-resistant and predator-proof option, a covered feeder can be constructed from a plastic container or a wide-mouthed jar.

To begin, select a clean plastic tub with a lid, such as a margarine or deli container.

Using a sharp utility knife or a drill with a wide bit, carefully create several entry holes around the side of the container, each about 1.5 inches in diameter.

These openings should be large enough for small birds like bluebirds to enter but small enough to deter larger, more aggressive birds like starlings or jays.

After creating the access holes, it is crucial to ensure all edges are smooth to protect the birds from injury.

Use a small piece of sandpaper or a fine file to carefully sand down the interior and exterior of each cut opening until no sharp plastic burrs remain.

Additionally, several small drainage holes should be drilled into the bottom of the container to prevent rainwater from accumulating and spoiling the mealworms.

This simple step is vital for maintaining a healthy and hygienic feeding environment for the visiting birds.

A hanging feeder can be fashioned from a plastic bottle, offering an elevated feeding station that is less accessible to ground pests.

Choose a sturdy, clean plastic bottle and drill or cut access ports into the sides, similar to the covered container design.

To create a perch, a small wooden dowel can be inserted through the bottle, passing through two aligned holes drilled just below an access port.

The bottle cap can be securely fastened, and a strong wire or string can be looped around the neck of the bottle for hanging from a tree branch or a feeder pole.

For individuals with basic woodworking skills, constructing a wooden feeder provides a durable and aesthetically pleasing solution.

A simple design can be made from a small block of untreated cedar, pine, or redwood, which are naturally resistant to rot.

A wide, shallow depression can be routed or carved into the top of the block to hold the mealworms, creating a contained feeding area.

Alternatively, a small box-like structure can be built with a solid bottom, short sides, and a removable roof for protection from rain and sun.

Regardless of the design, proper drainage is a non-negotiable feature for any outdoor feeder.

For wooden or plastic models, drilling a series of small holes in the base allows rainwater to escape, keeping the mealworms dry and preventing the growth of mold and bacteria.

This not only protects the quality of the food but also safeguards the health of the birds that frequent the feeder. Neglecting drainage can quickly turn a helpful feeding station into a source of disease.

Once the feeder is constructed, its placement is key to its success.

It should be situated in a relatively open area to allow birds to spot it easily, but close enough to trees or shrubs to offer a quick retreat from predators like hawks or cats.

It may take some time for birds to discover the new food source, so patience is essential.

Placing a few brightly colored berries or a small amount of familiar seed near the feeder initially can help draw attention to the new offering.

Finally, maintaining the feeder is just as important as its construction.

A regular cleaning schedule, involving scrubbing the feeder with a mild soap and water solution, should be established to prevent the buildup of waste and bacteria.

The feeder should be completely dry before it is refilled with fresh mealworms.

Consistent maintenance ensures a safe and inviting environment, encouraging birds to return regularly and providing them with a reliable source of high-energy food throughout the year.

Key Considerations for Feeder Construction and Use

1. Material Safety

   The choice of materials for constructing the feeder is of utmost importance for the well-being of the birds. Always opt for non-toxic substances, such as untreated wood (cedar, pine), glass, ceramic, or food-grade plastics.

   Avoid using materials treated with chemicals, paints, or stains that could leach into the food and harm the birds.

   If building a wooden feeder, ensure any screws or nails are rust-proof, such as stainless steel, to prevent corrosion and maintain structural integrity over time.

2. Effective Drainage

   Proper drainage is critical to prevent the mealworms, whether live or dried, from becoming waterlogged and spoiling. Rainwater accumulation can lead to mold and bacterial growth, which can be fatal to birds.

   To ensure adequate drainage, drill several small holes (approximately 1/8 to 1/4 inch in diameter) in the bottom of the feeder.

   This simple step maintains a hygienic environment and ensures the food remains fresh and appealing to your avian visitors.

3. Predator and Pest Deterrence

   A well-designed feeder should discourage unwanted visitors like squirrels, raccoons, and larger, more aggressive birds.

   For ground feeders, placing them within a wire cage with openings large enough for small birds but too small for squirrels can be effective.

   For hanging feeders, incorporating a baffle above or below the feeder can prevent mammals from climbing to it.

   The size of the entry ports can also be tailored to exclude larger bird species, ensuring the intended smaller, insect-eating birds can feed peacefully.

4. Bird Accessibility and Safety

   While containing the mealworms is important, the feeder must be easily accessible to the target bird species.

   The edges of the feeder should not be too high or steep for a bird to comfortably perch and reach the food.

   Any holes or openings must be sanded smooth to prevent injury to birds’ feet, beaks, and feathers.

   For hanging models, providing a small perch near the access port can make feeding easier and more comfortable for the birds.

5. Containment of Live Mealworms

   If offering live mealworms, the feeder design must prevent them from escaping. A container with smooth, inward-curving, or vertical sides at least one inch high is typically sufficient to keep the larvae contained.

   Glass, glazed ceramic, or smooth plastic are excellent materials for this purpose.

   Avoid rough-textured materials like un-sanded wood for the interior of the feeding area, as this can provide a foothold for the mealworms to crawl out.

6. Routine Cleaning and Hygiene

   Maintaining a clean feeder is essential for preventing the spread of avian diseases. The feeder should be cleaned every one to two weeks, or more often if it is heavily used or exposed to rain.

   Disassemble the feeder if possible and scrub all surfaces with a solution of nine parts water to one part vinegar or a very mild dish soap.

   Rinse thoroughly with clean water and allow it to dry completely before refilling with fresh mealworms.

7. Strategic Placement

   The location of the feeder significantly impacts its usage and the safety of the birds. Place the feeder in a location that is quiet and sheltered from strong winds.

   It should be about 10-15 feet away from dense shrubs or trees, providing birds with a safe place to retreat from predators like hawks.

   At the same time, avoid placing it too close to windows to minimize the risk of bird collisions; if it must be near a window, it should be within three feet so birds cannot build up enough speed to cause serious injury.

Advanced Tips for Optimal Mealworm Feeding

• Offer a “Calling Card” to Attract Birds

  When introducing a new feeder, birds may not recognize it as a food source. To attract their attention, especially species like bluebirds, consider creating a visual cue.

  Placing a small, bright blue object, such as a bottle cap or a piece of ribbon, near the feeder can pique the curiosity of bluebirds.

  Some enthusiasts also use a specific whistle or call just before filling the feeder, which can train the birds to associate that sound with the arrival of food over time.

• Combine Mealworms with Other Offerings

  To appeal to a wider variety of birds and provide a more balanced diet, consider offering mealworms alongside other foods.

  A platform feeder is ideal for this, as it allows for separate sections or small dishes for different items.

  Placing a small dish of mealworms next to offerings like sunflower hearts, suet pellets, or chopped fruit can attract birds that might not come for mealworms alone, encouraging them to sample the new food source.

• Manage Live Mealworms Effectively

  For those offering live mealworms, a few techniques can enhance the feeding experience.

  To slow down active mealworms and make them easier for birds to eat, they can be refrigerated for a short period before being placed in the feeder.

  Additionally, dusting the mealworms lightly with calcium powder, available from pet supply stores, can provide an extra nutritional boost, which is especially beneficial for female birds during egg-laying season.

• Establish a Consistent Feeding Routine

  Birds are creatures of habit and are more likely to frequent a feeder that provides a reliable food source.

  Try to refill the mealworm feeder at the same time each day, such as early in the morning when birds are most active.

  This consistency helps birds learn when to visit and can lead to them waiting nearby in anticipation. A dependable schedule is particularly crucial during harsh weather or the breeding season when energy demands are high.

• Adapt the Feeder for Different Seasons

  Seasonal adjustments can make the feeder more effective throughout the year. In the summer, place the feeder in a shaded spot to protect the mealworms from overheating and spoiling quickly.

  During winter, ensure the feeder is sheltered from snow and ice, and consider offering dried mealworms, which are less affected by freezing temperatures.

  Providing this high-protein food in winter can be a lifeline for birds when other insect sources are unavailable.

The nutritional profile of mealworms makes them an exceptional food source for wild birds. They are rich in protein, fat, and essential nutrients, which are vital for feather growth, energy, and overall health.

This high-protein content is particularly beneficial during the nesting season, as it supports healthy egg development and provides fledgling birds with the strength needed for their first flights.

Offering mealworms supplements a bird’s natural diet, especially in urban or suburban areas where natural insect populations may be limited.

A variety of bird species are drawn to mealworms, many of which do not typically visit seed feeders. The most famous enthusiasts are Eastern Bluebirds, which can be difficult to attract otherwise.

Other species that readily consume mealworms include American Robins, wrens, chickadees, nuthatches, and even some types of woodpeckers.

By providing this specific food, a garden can become a haven for a more diverse avian population, offering a more complete and engaging birdwatching experience.

A common consideration is whether to offer live or dried mealworms, as each has distinct advantages. Live mealworms provide hydration and their movement is a powerful attractant for birds, often enticing them more effectively.

However, dried mealworms are more convenient, have a longer shelf life, are less expensive, and do not require special care or containment.

Many birds will readily accept dried mealworms, especially after they have been rehydrated by soaking them in warm water for a few minutes.

Maintaining a year-round feeding schedule offers continuous support to local bird populations. While many people focus on feeding during the winter, birds face challenges in every season.

In spring, mealworms provide crucial energy for migration and breeding. In summer, they supplement the diet of busy parents feeding hungry chicks.

In autumn, they help birds build fat reserves for the upcoming migration or winter, making a consistent supply a valuable resource for their survival.

Providing a supplementary food source like mealworms can have a positive impact on the local ecosystem.

By supporting a healthy and diverse bird population, one also supports natural pest control, as many of these same birds will consume garden pests. Furthermore, a thriving bird community contributes to pollination and seed dispersal.

A well-maintained feeding station is a small but meaningful way to bolster the health of the immediate environment and support its natural cycles.

Proper sourcing and storage of mealworms are essential for providing a quality food source. Mealworms can be purchased from wild bird supply stores, pet stores, or online retailers that specialize in live insects.

Live mealworms should be stored in a refrigerator in a container with a ventilated lid and a substrate like oat bran, which keeps them dormant and extends their life.

Dried mealworms should be kept in a cool, dry place in an airtight container to maintain their freshness and prevent moisture contamination.

Even with a well-designed feeder, some common problems may arise. One frequent issue is dominance by larger, more aggressive birds like starlings or grackles.

This can often be solved by using a feeder with a protective cage or adjustable-weight perches that only allow smaller birds to access the food.

Another problem is ants being attracted to the feeder; this can be mitigated by creating a small “moat” of water around the feeder pole or using a commercially available ant guard.

The role of insects in the avian diet cannot be overstated, particularly for nestlings.

The vast majority of terrestrial bird species feed their young an exclusive diet of insects and other arthropods, regardless of what the adult birds eat.

Insects like mealworms are soft, easily digestible, and packed with the protein necessary for rapid growth.

Providing mealworms during the breeding season directly supports the successful rearing of the next generation of birds in the area.

A mealworm feeder can be a central component of a larger, bird-friendly landscape. To create a truly inviting habitat, it is beneficial to combine feeding stations with other essential elements.

This includes providing a clean water source, such as a birdbath, for drinking and bathing.

Planting native shrubs and trees that produce berries, seeds, and nectar, as well as attract native insects, will create a comprehensive sanctuary that meets all of a bird’s needs for food, water, and shelter.

When sourcing mealworms, it is worthwhile to consider the environmental impact of their production. Opting for suppliers that raise mealworms sustainably can make a difference.

Sustainable farming practices often involve using organic feed for the mealworms and minimizing waste and energy consumption.

Supporting companies that are transparent about their farming methods ensures that the effort to help local birds does not inadvertently contribute to broader environmental issues, aligning the hobby with a deeper commitment to ecological stewardship.
