6 Best Dried Insect Mixes for Nesting Birds
High-protein dried insects are vital for nesting birds. We review the 6 best mixes to support egg-laying and ensure healthy, thriving fledglings.
You hear it before you see it—the frantic, high-pitched chirping from a hidden nest. That sound means parent birds are working overtime, a relentless cycle of hunting and feeding. During nesting season, their need for protein skyrockets, and the insects they can find on your property become a critical resource. Offering a high-quality dried insect mix in your feeders is one of the most direct ways you can support their success.

Why Nesting Birds Crave High-Protein Insects
The entire process of raising a family is an immense energy drain for wild birds. From building the nest and laying eggs to incubating them around the clock, their metabolic rate is in overdrive. Protein is the essential fuel that powers this entire operation.
Once the chicks hatch, the demand doubles. Those tiny, fast-growing bodies require a constant supply of protein for proper muscle, organ, and feather development. Parent birds will spend nearly every daylight hour hunting for caterpillars, spiders, and beetles to satisfy the gaping mouths in the nest. A single clutch of chickadees can require thousands of insects before they fledge.
Providing a supplemental source of dried insects can be a game-changer, especially during a cold snap or a dry spell when natural insect populations dip. It gives parent birds a reliable, high-energy food source, reducing their foraging stress and increasing the odds that their young will grow up strong and healthy. This isn’t about replacing their natural diet; it’s about providing a crucial safety net when they need it most.
Kaytee Mealworms: A Widely Available Classic
If you’ve ever thought about feeding insects to birds, you’ve seen Kaytee Mealworms. They are the standard, available everywhere from local feed co-ops to big-box hardware stores. Their accessibility is their biggest strength; you can always find them when you need them.
Birds like bluebirds, wrens, robins, and chickadees absolutely love them. They are a pure, high-protein treat that can quickly attract insect-eaters to your yard. Because they are so light and dry, they are easy to store in a sealed container and handle without any mess.
However, it’s crucial to understand their primary drawback: mealworms are low in calcium. A diet too heavy in mealworms without other calcium sources can lead to weak eggshells for laying females and poor bone development in chicks. Think of them as a high-energy candy bar—a fantastic supplement, but not a complete meal.
Grubblies: Calcium-Rich Black Soldier Fly Larvae
Grubblies directly address the calcium deficiency found in mealworms. Made from dried Black Soldier Fly Larvae (BSFL), they are naturally packed with calcium. In fact, they have a much healthier calcium-to-phosphorus ratio, which is vital for birds’ bone and eggshell health.
This makes BSFL a nutritionally superior choice, especially during nesting season. You’re not just providing protein; you’re offering a more balanced supplement that supports the fundamental needs of both parents and their developing young. This can be particularly important for bluebirds, which are known to suffer from calcium deficiencies.
Many BSFL producers, including Grubblies, raise their larvae on pre-consumer food waste, turning potential landfill material into valuable animal feed. This sustainable production model is a major plus for anyone trying to make environmentally conscious choices on their property. Some birds accustomed to mealworms might take a day or two to try them, but their nutritional benefits are well worth the transition.
Happy Hen Treats Mealworm Frenzy for Bluebirds
This product is a straightforward, high-quality offering of what it promises: whole-dried mealworms. While the "for Bluebirds" branding is smart marketing, these mealworms are excellent for any insect-eating bird, from wrens to woodpeckers. The key here is consistency and quality.
Happy Hen Treats has a good reputation for clean, whole insects, which isn’t always the case with bulk, off-brand mealworms that can sometimes contain a lot of dust and broken pieces. If your primary goal is to attract and support a local bluebird population, this is a reliable and effective choice. Bluebirds are notoriously picky eaters and often prefer mealworms over other offerings.
Just like any other mealworm product, remember to offer it in moderation. Consider it a targeted treat to draw in specific birds or to provide an extra boost during a critical time. Pair it with a calcium-rich food source elsewhere in your yard, like crushed eggshells or a BSFL mix, to create a more balanced offering.
Audubon Park Songbird Selections Insect Blend
Sometimes, variety is the key to attracting a wider range of species. The Audubon Park Insect Blend moves beyond a single-ingredient offering by mixing mealworms with other dried insects, often including crickets or other grubs. This creates a more diverse texture and nutritional profile in the feeder.
A blend like this can be a great way to see what your local birds prefer. A robin might go for the mealworms while a nuthatch might be more interested in the crickets. It provides more naturalistic variety and can appeal to birds that might otherwise ignore a feeder full of just one thing.
The tradeoff with any blend is a lack of control. You can’t be sure of the exact ratio of ingredients, and the overall nutritional profile might vary from bag to bag. It’s an excellent choice for a general-purpose songbird feeder aimed at broad appeal, but if you have specific nutritional goals (like boosting calcium), a single-ingredient product like BSFL is a more direct solution.
Fly Grubs: Sustainable Protein for Your Feeders
Fly Grubs are another excellent brand of Black Soldier Fly Larvae, competing directly with Grubblies. They offer the same core benefits: a high-protein content combined with a naturally high level of calcium. This makes them a fantastic, nutritionally balanced supplement for nesting birds.
The biggest selling point for BSFL products like Fly Grubs is the sustainability factor. These insects are incredible recyclers, efficiently converting food scraps and agricultural byproducts into protein. For the hobby farmer who values closed-loop systems and resourcefulness, feeding BSFL aligns perfectly with that ethos. You’re supporting your birds with a product that helps reduce food waste.
When deciding between Fly Grubs and other BSFL brands, the choice often comes down to what’s available in your area and the price point. Both are nutritionally superior to mealworms for supporting nesting birds. Offering them is a simple switch that can have a significant positive impact on the health of your local bird population.
Picker-Necker’s Bulk Mealworms for Big Flocks
Once you start feeding insects regularly, you’ll notice one thing quickly: a small bag doesn’t last long. If you have an established population of bluebirds, wrens, and chickadees visiting your feeders daily, the cost can add up. This is where buying in bulk becomes a necessity.
Brands like Picker-Necker specialize in selling large quantities—think 5, 10, or even 20-pound bags—of dried mealworms. The cost per ounce drops dramatically, making a daily feeding habit much more sustainable for your wallet. This is the most economical approach for anyone committed to providing a consistent food source for a large number of birds.
The main consideration with bulk buying is storage. You absolutely need an airtight, rodent-proof container to keep the mealworms fresh and protected from pests. A galvanized steel can or a heavy-duty plastic bin with a locking lid stored in a cool, dry place like a garage or shed is ideal. And again, even when buying in bulk, remember that mealworms are a supplement, not a complete diet.
Best Ways to Offer Dried Insects to Wild Birds
How you offer insects is just as important as what you offer. The best feeder is a simple platform feeder or a specialized mealworm feeder with smooth sides and a roof. The roof is key—it keeps the lightweight insects from getting soggy in the rain or blowing away in the wind.
Placement matters. Position your feeder near natural cover, like a thick bush or a tree line. Birds are vulnerable at feeders, and having a quick escape route nearby makes them feel much safer and more likely to visit. Offering the insects first thing in the morning ensures they’re available when birds are most actively foraging for their young.
Finally, practice moderation. A small handful of dried insects a day is more than enough for most situations. You can mix them in with seed, but they are often more effective when offered on their own in a separate dish. This prevents the insects from getting lost in the mix and allows insect-eaters to find them easily. The goal is to supplement their natural hunting, not replace it.
Ultimately, choosing the right dried insect mix comes down to your specific goals. Whether you’re prioritizing the balanced nutrition of Black Soldier Fly Larvae, the targeted appeal of mealworms, or the cost savings of buying in bulk, your efforts provide a vital resource. By offering a clean, reliable source of protein, you’re giving nesting birds a powerful advantage during the most demanding season of their lives.
