Feeding a bearded dragon is a daily ritual, and the choice of feeder insect directly impacts their health, activity levels, and even their willingness to eat. The wrong bug can be a gut-loading failure, a choking hazard, or a carrier of parasites, making selection a critical husbandry decision.
I’m Mo Mahin — the founder and writer behind Furric. I spend my time comparing the nutritional profiles of feeder insects, analyzing customer reports on live arrival rates, and cross-referencing calcium-to-phosphorus ratios to find what truly works for captive reptiles.
After digging through hundreds of verified buyer experiences and supplier data, I’ve sorted the market into reliable picks that simplify your shopping. This guide covers the top insects for bearded dragon diets, focusing on survival rates, nutritional value, and practical feeding logistics.
How To Choose The Best Insects For Bearded Dragon
The right feeder insect must balance protein content, shell digestibility, and ease of keeping. You cannot just grab any bug — the calcium-to-phosphorus ratio, moisture content, and chitin thickness all determine whether your dragon digests it well or risks impaction.
Nutritional Profile: Protein, Calcium & Phosphorus
Dubia roaches offer roughly 22% protein with a calcium content of 283 ppm, making them superior to crickets which usually hover around 18–20% protein. Superworms are higher in fat, so they work better as treats rather than staple feeders. Always look for insects that can be effectively gut-loaded — roaches have a longer digestive tract, absorbing more nutrients before being fed off.
Live Arrival & Hardiness
Shipping live insects is stressful. Crickets are fragile and often arrive with high mortality in cold weather, while dubia roaches are hardy and can survive 5–6 days in transit. Banded crickets have a longer lifespan than common house crickets and handle shipping slightly better. Check whether the seller offers a live arrival guarantee and includes overcounts to cover expected losses.
Size Appropriateness for Your Dragon
The rule is simple: the insect should be no larger than the space between your dragon’s eyes. Adult dragons (14 inches or larger) can take 1-inch crickets, adult dubia roaches, or large superworms. Juveniles need smaller prey — ½-inch crickets or medium roaches — to avoid choking or impaction. Size consistency matters; some suppliers send mixed sizes, which complicates portion control.
Gut-Loading and Dusting Potential
Insects are only as nutritious as what they eat. Dubia roaches have a longer digestive tract that holds nutrients longer, meaning they pass more calcium to your dragon after dusting. Crickets need to be fed fruits and veggies for at least 24 hours before feeding off. Superworms can be gut-loaded but should be offered within a day or two of receipt.

In‑Depth Reviews
1. Live Dubia Roaches (10 Adult Male)
These adult male dubia roaches from Rainbow Mealworms are a staple feeder that solves two common problems: cricket odor and cricket escape. With 22% protein and 283 ppm calcium, they out-nutrition most crickets on the market. Buyers consistently report near-100% live arrival, even after 5–6 days in cold transit, which is remarkable for live insects.
The high meat-to-shell ratio means your dragon digests more and passes less undigested chitin. Because these are males only, you do not have to worry about accidental colony establishment in your home. The seller includes a live delivery guarantee by offering hold-for-pickup shipping to your local post office, and customers appreciate the free sticker included as a thoughtful touch.
Mid-range pricing for a 10-count pack makes this a manageable trial size before committing to larger quantities. The roaches are hardy enough to be gut-loaded over several days, and their longer digestive tract means they retain more calcium powder after dusting. This is the most balanced, low-hassle option for daily feeding.
Why we love it
- Consistently 100% live arrival in cold weather
- High calcium-to-phosphorus ratio ideal for bone health
- No odor or noise compared to crickets
Good to know
- Only 10 roaches per pack — better for trialing than bulk feeding
- Males only, so not suitable for breeding colonies
2. Adult Dubia Roaches 20 Females & 10 Males
This 30-count breeding kit gives you 20 females and 10 males specifically selected to start a thriving colony. Buyers report that these roaches arrive at around 1.5 inches in length — a size perfect for adult bearded dragons. The colony establishment feedback is strong: multiple customers note seeing babies within weeks and describe the roaches as bigger and healthier than any pet store alternative.
The seller requires you to add “HOLD” to your shipping address for a live arrival guarantee and does not ship to Florida, Hawaii, or Alaska due to state regulations. Almost every reviewer reports just one or two losses in transit, which is acceptable for a live insect shipment. The roaches arrive clean with no noticeable smell, which is a major upgrade over cricket shipping.
Premium-tier pricing reflects the colony-starter value rather than a single-feeding pack. One reviewer noted that older individuals may die within 2–3 weeks, so this is best used for breeding rather than as a long-term feeder supply on its own. Once established, a colony can provide a continuous, low-cost feeder source for months.
Why we love it
- Proper male-to-female ratio for successful colony breeding
- Large, healthy roaches — bigger than pet store stock
- Minimal transit deaths and clean packaging
Good to know
- Not shippable to FL, HI, or AK due to laws
- Some roaches may be old — better for feeding than long-term breeding
3. Bassett’s Cricket Ranch 500 Medium (1/2″) Banded Crickets
Basset’s Cricket Ranch offers 500 medium banded crickets at a price point that undercuts most pet store alternatives. Banded crickets have a longer lifespan than common house crickets and are easier to keep alive at home. Verified reviewers report 99% live arrival with fast shipping, and the crickets are often described as lively and well-fed upon delivery.
The ½-inch size is ideal for juvenile to sub-adult bearded dragons, but several buyers note that sizes can be inconsistent, with many measuring closer to ¾ inch to 1 inch. If your dragon is small, you may need to separate out the larger individuals. The crickets come in a ventilated bag and can be transferred to a cricket keeper with egg crate for longer storage.
Mid-range pricing per count makes this an economical bulk option. However, a small number of reviews report contamination issues — spiders, centipedes, or beetles mixed in — and DOA batches in extreme weather. The seller offers customer service to replace dead crickets, but the inconsistency means this is best ordered during moderate temperatures. Overall, the value per live cricket is hard to beat.
Why we love it
- Excellent price per cricket — great for bulk feeding
- Banded crickets last longer and are hardier than house crickets
- Fast shipping with high live arrival rates in good weather
Good to know
- Size inconsistency — some crickets are larger than 1/2 inch
- Risk of contamination and DOA in extreme heat or cold
4. Superworm 300 Large Superworms (Bulk Organic)
Superworms are larger and fatter than mealworms, making them an excellent high-protein treat for adult bearded dragons. This 300-count bulk pack from Many Mealworms delivers plump, active worms with nearly 100% live arrival according to the majority of reviews. Multiple buyers note that these worms survived over 25 days when stored properly with vegetables for moisture.
The 16-ounce bag is organic and labeled as high-protein seafood flavor, though your dragon will not care about the label — they will just register the movement and bite. Superworms are fattier than roaches or crickets, so they should make up no more than 10–20% of the diet. They work great as a treat or to stimulate a picky eater’s appetite.
Premium-tier pricing per count reflects the organic certification and the convenience of bulk. A few negative reviews mention undercounting — one buyer received only 50 worms instead of 300 — which is a risk with any live insect seller. However, the overwhelming majority report chunky, healthy worms that their reptiles love. If your dragon needs extra protein or you want a treat that keeps well, this is a solid pick.
Why we love it
- Chunky, large worms with high live arrival rates
- Long shelf life — can last 25+ days with proper storage
- Organic certification for cleaner gut-loading
Good to know
- Higher fat content — best used as a treat, not a staple
- Some reports of undercounting or missing quantities
5. Josh’s Frogs 1″ Large Adult Banded Crickets (1000 Count)
Josh’s Frogs supplies 1,000 large adult banded crickets specifically recommended for bearded dragons 14 inches or larger. Banded crickets are superior to house crickets — they live longer, are less prone to disease, and provide better nutrition. The seller uses a mix of shipping carriers based on your location and weather to optimize live arrival, and includes a virtual care sheet with storage and feeding instructions.
The 1-inch size is perfect for fully grown adult dragons, eliminating the need to sort by size. Buyers report that spring and fall orders arrive with almost all crickets alive, healthy, and free of smell or unwanted pests. The seller offers a live arrival guarantee and provides generous overcounts to cover expected losses.
Premium-tier pricing reflects the larger count, specialized banded cricket genetics, and the customer service backing. A handful of negative experiences involve DOA shipments in winter and incorrect sizing, but Josh’s Frogs typically works to correct issues. For owners of multiple adult dragons or those who prefer a bulk cricket supply with professional support, this is the most reliable large-volume option.
Why we love it
- Banded crickets live longer and are healthier than standard house crickets
- Large 1-inch size — ready for adult dragons without sorting
- Strong live arrival guarantee and customer service
Good to know
- Bulk 1,000 count requires a proper cricket keeper and storage plan
- Winter shipping can result in high mortality despite packaging
