ProRep Bug Grub is a complete dry diet formulated specifically for the breeding and maintenance of livefood insects. Whether you're running a small colony or managing large-scale feeder insect stocks, it delivers consistent, high-quality nutrition to keep your livefoods in prime condition before they reach your animals. Available in multiple sizes to suit different colony setups and usage levels.
What It Does
A well-fed feeder insect is a nutritious feeder insect. Bug Grub ensures your crickets, locusts, and other livefoods are gut-loaded with a balanced diet high in both calcium and protein — directly improving the nutritional value passed on to your reptiles, amphibians, or invertebrates at feeding time.

How to Use
Place Bug Grub in a shallow dish inside your feeder insect enclosure, making sure the insects can access it freely. Only provide enough for one to two days at a time — moisture causes mould, so replace regularly and never allow it to become wet. Always offer Bug Gel or small pieces of carrot alongside it as a moisture source, as Bug Grub itself is a dry food.
