Live Mealworms are best offered in moderation as part of a varied feeding routine. The right amount depends on the type of animal, its size, and its regular diet.

For most pets live mealworms work best as an occasional treat rather than an everyday staple. Offering them a few times per week — or during bonding and training moments — keeps them exciting and prevents overfeeding.

Treats should complement a balanced primary diet, not replace it. For wild birds, mealworms are best offered as a supplemental food alongside seeds, suet, and natural foraging. Providing reasonable portions and a variety of foods supports natural feeding behaviors and keeps your backyard setup balanced.

Yes. Mealworms are widely accepted by many backyard bird species and are especially popular with bluebirds, robins, wrens, chickadees, and woodpeckers.

Milo’s Mealworms offers Medium, Large, and Giant live mealworms. The best size depends on the species, age, and size of the animal you’re feeding.

The main difference is size. Medium mealworms are a convenient choice for smaller animals or when a smaller mealworm is preferred. Large mealworms work well for many adult animals, while Giant mealworms may be appropriate for larger animals that can comfortably manage them.
