Wild Birds
The garden's busy little songbirds
Robins, blackbirds, tits and sparrows naturally spend much of their day hunting insects. Calciworms help bring that natural food source into the garden, giving birds a protein-rich boost, especially during nesting season when chicks need soft, nutritious food.
Key benefits
- Calcium essential for egg laying females and healthy bones in growing chicks
- Soft, protein-rich insect food for the breeding season
- High-fat dried larvae help adult birds build condition for autumn and winter
- Dried Calciworms can be soaked in water for nesting season
- A calcium-rich alternative to mealworms
Did you know? The RSPB advises against seeds and peanuts through summer to reduce disease spread, but recommends insects for birds all year round.
Hedgehogs
The garden's gentle night-time explorer
Hedgehogs are natural insectivores with a big appetite for nutritious invertebrates. Calciworms provide the perfect balance of protein and calcium to support their health and energy on their nightly foraging rounds.
Key benefits
- Naturally high in calcium for strong bones and teeth
- High in protein to support growth and vitality
- Around 60× more calcium than dried mealworms
- Easily digestible and grain-free
- Irresistible taste hedgehogs love
Did you know? Hedgehogs can eat up to 200g of insects a night. Calciworms are a natural favourite.
Chickens
The backyard's busiest little foragers
Chickens are curious, social birds with a serious love of scratching, pecking and exploring. Insects are a natural part of their diet, and Calciworms bring that instinctive foraging behaviour back into the garden flock.
Key benefits
- Naturally high in calcium to support strong eggshells
- Rich in protein and beneficial fats
- Essential amino acids to help prevent feather pecking
- Supports laying condition and long-term hen health
- Encourages scratching, pecking and active foraging
Did you know? Chickens do not have teeth. Instead they swallow small stones and use their gizzard to grind food down.
Reptiles
The terrarium's sun-loving insect hunters
From bearded dragons and geckos to skinks and chameleons, insect-eating reptiles rely on variety, movement and the right nutritional balance. Calciworms are soft-bodied and naturally rich in calcium, making them a useful addition to a varied reptile diet.
Key benefits
- Naturally high in calcium to support healthy bones and growth
- No gut loading or nutrient dusting required
- Soft-bodied larvae that are easy to eat and digest
- Wriggly live food that triggers natural hunting behaviour
- Available in a range of sizes for different reptiles and life stages
Did you know? Many reptiles use their tongue to gather scent particles from the air, processing them through a special organ in the roof of their mouth.
Fish
The water's curious little hunters
From aquariums to garden ponds, many fish are natural opportunistic feeders. Insects and insect larvae form part of many wild diets, and Calciworms add insect-based variety to feeding routines for aquarium fish, pond fish and koi alike.
Key benefits
- High in antimicrobial lauric acid
- Insect protein linked with improved parasite resilience
- Small larvae ideal for many aquarium fish
- Larger larvae make a great floating treat for koi and pond fish
- Adds natural insect-based variety to the diet
Did you know? Many pond fish naturally feed on insects and larvae that fall onto the water’s surface, making floating insect treats an engaging part of their feeding routine.
Amphibians
The terrarium's tiny ambush hunters
Tree frogs, toads and salamanders are skilled predators that rely on movement and timing to catch their food. They strike fast and swallow prey whole, so soft, wriggly Calciworms can make a useful addition to a varied amphibian diet.
Key benefits
- Live, wriggly food that triggers a natural feeding response
- Soft-bodied larvae suitable for animals that swallow prey whole
- Naturally rich in calcium to support growing amphibians and breeding females
- A calcium-rich alternative to mealworms
- Complements crickets, flies, worms and other feeder insects
Did you know? Some frogs use their eyes to help swallow. When they blink, their eyes press down into the roof of the mouth to help push food toward the throat.
Invertebrates
Tiny hunters with serious instincts
From jumping spiders and tarantulas to praying mantises and scorpions, many pet invertebrates are skilled predators. They rely on movement, patience and quick reactions, so live, wriggly Calciworms can make a natural and stimulating prey choice.
Key benefits
- Available in a range of sizes for different mouth sizes
- Wriggly live food that triggers a natural hunting response
- Soft-bodied larvae suitable for many predatory invertebrates
- Larger larvae can hatch into flies, ideal prey for praying mantises
- Complements crickets, roaches and other feeder insects
Did you know? Scorpions glow blue-green under ultraviolet light, thanks to special compounds in their outer shell.
Exotic Pets
Specialist animals with wild instincts
From small mammals and specialist zoo animals to omnivorous exotics, many species benefit from foods that encourage natural foraging and hunting behaviour. Our Calciworms are fed to around 30 different species in zoo settings, including otters, mongoose and small primates.
Key benefits
- A safe and nutritious way to introduce natural insect protein
- Suitable for many insectivorous and omnivorous exotic animals
- Naturally high in calcium
- Available live or dried to suit different feeding routines
- Helps encourage natural foraging, searching and hunting behaviours
Did you know? Many small primates and carnivores spend a large part of their day searching, sniffing, digging and exploring for food. Scatter feeding insects can help turn mealtimes into enrichment.
