Grubs | High Protein Nature's Grubs 350g | Mother Nature's

Nature's Grubs 350g is a premium, single-ingredient dried insect treat for wild birds, produced in Canada by Chin Ridge Seeds. Each bag contains dried black soldier fly larvae (BSFL) — a naturally high-protein, high-calcium food source that wild birds instinctively seek out during nesting season, moult, and cold weather. All natural, no preservatives, no additives, and produced using recycled food products in an earth-friendly closed-loop process. The 350g bag is ideal for trial use, supplemental feeding, or as a high-value addition alongside seed mixes at an existing feeder station.

Why Dried Insect Larvae for Wild Birds

Insects are a critical natural food source for most wild bird species, particularly during breeding season when parent birds require high-protein food to feed nestlings, and during moult when protein supports rapid feather regrowth. Black soldier fly larvae are especially valued for their high calcium content — significantly higher than mealworms — which supports eggshell formation in nesting females. Dried BSFL deliver this nutritional profile in a shelf-stable, mess-free format that can be offered in feeders, on trays, or scattered on the ground.

Best Suited For These Birds

Dried insect larvae attract insectivorous and omnivorous wild bird species, including:

• American Robins — strongly attracted to larvae; a natural substitute for earthworms during dry or frozen ground conditions
• Eastern Bluebirds & Mountain Bluebirds — insectivores that readily accept dried larvae in open tray feeders
• Black-capped Chickadees — will take larvae from feeders and mix them with seed
• White-breasted & Red-breasted Nuthatches — attracted to high-protein food sources at feeders
• Downy & Hairy Woodpeckers — readily consume dried larvae from platform and tray feeders
• House Wrens & Carolina Wrens — insectivores that benefit from dried larvae as a supplement
• Tufted Titmice — readily accept dried larvae alongside seed at feeders
• Cedar Waxwings — will take larvae during nesting season when protein demand is high
• American Tree Sparrows — attracted to larvae scattered on the ground or low trays
• Barn Swallows & Tree Swallows — insectivores that may take larvae from open platform feeders

Dried larvae are particularly effective during spring nesting season and late summer moult, when wild birds actively seek high-protein food sources beyond what seed mixes alone provide.

Ideal For

• Birdwatchers wanting to attract insectivorous species not drawn to seed alone
• Open platform feeders, tray feeders, bluebird feeders, and ground feeding areas
• Spring and summer nesting season supplemental feeding
• Late summer and fall moult support when birds need extra protein for feather regrowth
• Cold weather feeding — high fat and protein content supports energy in winter when insects are unavailable
• Trial and supplemental use — the 350g bag is ideal for adding larvae to an existing seed feeding station without committing to a larger quantity

Feeder Compatibility

Dried larvae are best offered in open platform feeders, tray feeders, or dedicated mealworm/larvae feeders with low sides that allow birds easy access. They can also be scattered directly on the ground or mixed into existing seed in a hopper or platform feeder. Bluebird feeders with small entry holes are particularly effective for targeting bluebirds and excluding larger species. Keep feeders dry — dried larvae can clump if exposed to moisture, so use a covered feeder or bring trays in during rain.
