Unlike seeds or dried grubs, live calci worms are soft, wriggling and easy to digest — exactly what nature intended. Sometimes garden birds can take a little time to get used to a new food. But once they recognise Calci Worms, they tend to go mad for them. Many people find their birds will even pick the calci worms out first, especially when they have chicks to feed. Robins, blackbirds, wrens and tits all love them, and you’ll soon see the difference as your feeders become a hive of activity. With natural insect numbers falling, calci worms provide the vital extra food that keeps garden birds and hedgehogs thriving. Whether you start with a small pack or stock up in bulk, you’ll quickly see why calci worms are the best choice for wildlife. 💚 Kind to Wildlife & the Planet Our calci worms are raised on surplus fruit and vegetables, helping to cut down food waste and lower emissions. For every kilogram of live grubs we produce, around 12kg of CO₂ is saved compared to imported Calci Worms and mealworms. With 7% of the UK’s emissions coming from rotting food waste, we’re proud to be doing our bit to turn a problem into a solution. Everything is done with care. We never use manure or animal waste, and our grubs are fully traceable and tested for safety. Unlike the cheap Chinese worms you’ll find in most shops, ours are grown right here in Cambridgeshire, so you know exactly where they come from. We’re a small startup farm run by Niki, Lucy, Helen and Joe, and we care deeply about the animals you feed, the environment, and the future of farming. Every order you place helps us keep pushing towards a better food system — one that works for wildlife, for people, and for the planet. 💡 Care & Feeding Tips Store in a cool place out of direct sunlight Feed directly or place in a shallow dish so the grubs can’t crawl away (a dog bowl works perfectly) Do not soak in water – these are live grubs and best fed as they are Provide fresh water nearby for birds and hedgehogs to keep them hydrated Why Buy From Us? This all began when I was studying at Cambridge University. I learned that the UK produces over 30,000 tonnes of food waste every single day, and most of it ends up rotting in landfill, releasing methane and driving climate change. In nature, organic waste is broken down by insects. But with natural insect populations plummeting, our wildlife is running short of the very food it depends on. That’s why we launched this startup farm in Cambridgeshire. By feeding surplus fruit and vegetables to our calci worms, we turn waste into high-quality nutrition for wild birds, hedgehogs, reptiles and fish. Every grub you buy helps cut emissions, supports British farming and gives nature a boost. Unlike the cheap Chinese calci worms and mealworms flooding the market, ours are fully traceable, grown on clean feed, and tested salmonella-free. Imports are often raised on questionable, even toxic substrates, then shipped halfway round the world. This adds to climate change and risks the health of the animals that eat them. Right now, our worms are helping garden birds and pets. But our mission is bigger. As a young startup, we’re working towards creating sustainable feed for chickens too, so they no longer rely on soya grown on deforested land in Brazil. We’re proud to be the UK’s first dedicated Calci Worm startup farm. When you buy from us, you’re not just feeding your animals, you’re backing a new way of farming that fights waste, cuts carbon, and builds a better food system. - Joe Halstead, AgriGrub CEO Your birds deserve better.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
