Black Crickets Extra-Large | Bag of 500 | Bulk Livefood

Black crickets are a staple feeder insect for reptile and amphibian keepers across the UK, and the extra-large size — measuring 20–30mm — is suited to adult animals that need a substantial, protein-rich meal. This bag of 500 is dispatched directly from the breeder and gut-loaded before packing, so they arrive in the best nutritional condition possible.

Size and Species Suitability

At 20–30mm, these are genuinely large crickets suited to adult reptiles, large amphibians, and insectivorous invertebrates. They're a strong choice for bearded dragons, water dragons, monitor lizards, skinks, basilisks, turtles, pacman frogs, and bullfrogs, as well as tarantulas and mantids. If you're keeping large adult insectivores, this is the size to reach for.

Gut-Loaded and Farm-Bred

Every batch is bred in controlled, ethical farm conditions and fed before dispatch — not an afterthought, but part of the preparation process. Gut-loading ensures the nutritional value is as high as it can be when your animal feeds. Farm-bred stock also means consistent sizing and lower parasite risk compared to wild-caught insects.

Packaging and Transit

Crickets arrive in a ventilated plastic tub with egg-box cardboard included to increase surface area, reduce crowding, and minimise trampling losses. Ventilation holes run along the sides to keep airflow moving while containing the insects securely. Seasonal adjustments are made to packaging: additional perforations are added during warmer months for cooling, and a heat pack may be included during colder periods to maintain a safe transit temperature.

Keeping Them in Good Condition

• House at room temperature, away from direct sunlight and draughts
• Feed regularly on fresh leafy greens, carrot, squash, or sweet potato — this maintains hydration and nutritional value
• Specialist gut-loading diets can be used to further boost their nutritional profile
• Remove uneaten food daily to prevent mould and keep the enclosure clean
• Provide adequate space and hiding spots to reduce overcrowding stress

Well-maintained crickets are significantly more nutritious than neglected ones. The effort put into housing them properly between delivery and feeding directly benefits your animal's health and digestion.
