Crickets

Crickets are the most widely used feeder insect in reptile keeping and have been a staple of the hobby for decades. They are readily available at virtually every pet store, come in a range of sizes suitable for reptiles from tiny hatchling geckos to adult bearded dragons, and trigger strong feeding responses in most insectivorous and omnivorous species because of their active movement patterns. For many keepers, crickets are the first feeder insect they ever purchase, and they remain a core part of feeding programs for millions of reptiles worldwide.

The nutritional value of a cricket depends almost entirely on what that cricket has been eating. This is the single most important thing to understand about feeding crickets to your reptiles, and it cannot be overstated. A cricket purchased from a pet store that has been sitting in a bare container with nothing to eat is little more than a crunchy shell full of empty calories. That same cricket, given twenty-four to forty-eight hours of quality food before being offered to your reptile, becomes a genuine nutritional delivery system carrying vitamins, minerals, and moisture directly into your animal's diet. This process is called gut-loading, and it transforms crickets from adequate feeders into excellent ones.

Calcium supplementation is the other critical piece of the cricket feeding equation. Even well-gut-loaded crickets have an inverted calcium-to-phosphorus ratio, meaning they contain more phosphorus than calcium. Since reptiles need roughly twice as much calcium as phosphorus in their diet, every cricket you feed should be lightly dusted with calcium powder before being offered to your reptile. This is not optional, and skipping this step consistently leads to metabolic bone disease, which is one of the most common and most preventable health conditions in captive reptiles.

Crickets do come with some drawbacks that every keeper should understand. They are noisy, they smell when kept in large numbers, they die easily if conditions are not right, and uneaten crickets left in a reptile enclosure can actually bite sleeping reptiles and cause skin injuries. None of these problems are insurmountable, but they are real considerations that factor into how you manage crickets as part of your feeding program.

This article covers everything you need to know about using crickets effectively, from purchasing and housing them to gut-loading, calcium dusting, proper sizing, and feeding techniques that maximize nutritional benefit while minimizing the hassles that come with these ubiquitous feeder insects.

Selecting the right size cricket for your reptile is the first practical decision you make every time you feed. The standard rule is that prey items should be no wider than the space between your reptile's eyes. For hatchling leopard geckos and small juvenile bearded dragons, this means pinhead or small crickets. Medium crickets suit juvenile to sub-adult animals, and large or adult crickets are appropriate for full-grown bearded dragons, adult chameleons, and similarly sized reptiles. Feeding crickets that are too large creates choking risk and potential impaction, particularly in smaller species, so err on the side of slightly smaller rather than slightly larger when you are unsure.

Gut-loading is the process of feeding your crickets nutritious food so that nutrition passes to your reptile when the cricket is consumed. Begin gut-loading at least twenty-four hours before feeding day, and ideally maintain your crickets on quality food at all times rather than only loading them right before use. Excellent gut-load foods include fresh collard greens, mustard greens, carrots, sweet potato, squash, and high-quality commercial gut-load products. Avoid feeding crickets lettuce, citrus, or anything with minimal nutritional value. The goal is to fill the cricket's digestive tract with nutrients your reptile needs, particularly calcium-rich vegetables that help offset the cricket's naturally poor calcium-to-phosphorus ratio.

Calcium dusting should happen immediately before feeding. Place the appropriate number of crickets in a plastic bag or cup, add a small amount of calcium powder, and gently shake or swirl until each cricket has a light coating. You want a visible dusting, not a thick paste - too much powder causes crickets to stop moving, which reduces your reptile's interest in eating them. Dust with plain calcium carbonate for most feedings and use calcium with vitamin D3 once or twice per week, unless your reptile has adequate UVB exposure that allows them to synthesize their own D3. A separate multivitamin dust can be used once weekly or biweekly depending on species requirements.

Housing crickets between purchase and feeding requires minimal setup but consistent attention. Keep them in a well-ventilated container - a plastic storage bin with a screened lid works well. Egg crate flats provide climbing surfaces that reduce overcrowding stress and die-offs. Maintain room temperature or slightly warmer, and provide fresh food and a moisture source such as water gel crystals or fresh vegetable slices. Do not use open water dishes, as crickets drown easily. Remove dead crickets daily to prevent bacterial growth and the characteristic ammonia smell that poorly maintained cricket containers develop.

When feeding crickets to your reptile, offer only the number your animal will consume within about fifteen minutes. Loose crickets left in the enclosure overnight hide in crevices, stop being gut-loaded since they have nothing to eat, and may chew on your sleeping reptile's skin, causing injuries that can become infected. Some keepers feed in a separate bare container to prevent escapees, while others use feeding tongs to offer crickets individually. Both approaches work well and eliminate the problem of leftover crickets in the enclosure.

Monitoring your reptile's response to cricket feedings helps you calibrate quantity, sizing, and frequency over time. A reptile that eagerly hunts and consumes all offered crickets within minutes is properly sized and hungry enough for the portion given. An animal that shows interest but cannot catch or swallow the crickets may need smaller prey. Consistent refusal of crickets in an animal that previously ate them well warrants investigation into temperature, health, or environmental factors rather than simply switching feeder species.

Bearded dragons are among the most common cricket consumers in the hobby, particularly as juveniles when their diet should consist primarily of insects. Young bearded dragons may eat thirty to fifty appropriately sized crickets per day spread across two to three feeding sessions. As they mature and transition to a primarily vegetable-based diet, cricket consumption drops to perhaps ten to twenty per day for adults, offered several times per week rather than daily. The high volume consumed by juveniles makes gut-loading and calcium dusting especially critical during this growth phase, as the nutritional quality of each cricket compounds across dozens of feedings per day.

Leopard geckos rely on crickets as a dietary staple throughout their lives since they are obligate insectivores that do not eat plant material. Adults typically eat five to eight appropriately sized crickets every two to three days. Leopard geckos are ground-dwelling hunters that prefer to chase their prey, so releasing crickets onto the enclosure floor triggers stronger feeding responses than tong feeding for most individuals. Keep a shallow dish of calcium powder in the enclosure at all times so your leopard gecko can self-supplement between feedings, which many of them learn to do regularly.

Chameleons are enthusiastic cricket hunters whose feeding behavior benefits from the movement and climbing activity that crickets provide. Most chameleons eat crickets by shooting their tongues from a perched position, so offering crickets in an escape-proof cup placed within tongue range or allowing them to climb on branches within striking distance works better than dumping them on the enclosure floor. Chameleons are particularly susceptible to over-supplementation with vitamin A, so follow species-specific supplementation schedules rather than dusting every feeding with multivitamins.

Smaller gecko species like house geckos, day geckos, and mourning geckos eat pinhead or small crickets and need tiny portions appropriate to their body size. For these species, two to four small crickets per feeding is often sufficient, and overfeeding causes obesity faster than in larger, more active species. The same gut-loading and dusting principles apply regardless of reptile size - even the smallest cricket going into the smallest gecko should be properly loaded and dusted.

Some reptile species that are primarily herbivorous as adults, such as blue-tongued skinks or uromastyx, may accept crickets as occasional treats or protein supplements without needing them as dietary staples. For these species, offering a few crickets once a week or less provides enrichment and supplemental protein without unbalancing a diet that should be predominantly plant-based.

Cricket die-offs frustrate keepers who purchase large quantities only to find half the container dead within days. The most common causes are overcrowding, inadequate ventilation, lack of food and water, temperature extremes, and ammonia buildup from decomposing dead crickets that were not removed promptly. Buying smaller quantities more frequently, maintaining clean housing conditions, and providing adequate food, moisture, and air circulation prevents most die-offs. If you consistently lose large percentages of purchased crickets, evaluate your storage setup rather than blaming the supplier, though poor quality from some sources is admittedly a real issue.

Cricket bites on reptiles are more common and more damaging than many new keepers realize. Hungry crickets will chew on sleeping reptiles, particularly around the eyes, ear openings, and toes where skin is thinnest. These bites cause wounds that can become infected and leave permanent scarring. The solution is straightforward - never leave uneaten crickets in the enclosure overnight. Feed only what your reptile will consume during an active feeding session, and remove any remaining crickets afterward. This single habit prevents virtually all cricket bite injuries.

Noise and odor are the most common lifestyle complaints about keeping crickets. Adult male crickets chirp loudly, especially at night, and a container of several hundred crickets produces enough sound to disrupt sleep if kept in a bedroom. The smell of a cricket container intensifies rapidly when hygiene lapses, as cricket waste and dead bodies produce ammonia. Keeping crickets in a well-ventilated space away from living areas, maintaining clean conditions, and using smaller quantities purchased more frequently all help manage these nuisances.

Nutritional complacency develops when keepers treat crickets as a complete food source without proper gut-loading and supplementation. Crickets straight from the pet store container, fed without gut-loading or calcium dusting, provide inadequate nutrition that leads to deficiencies over time. Metabolic bone disease from calcium deficiency is the most serious consequence, but general poor health, slow growth in juveniles, and weakened immune function also result from feeding unsupplemented crickets. Every cricket your reptile eats should be gut-loaded and dusted - this is a non-negotiable foundation of insectivore nutrition.

Cricket escapees are an inevitable part of keeping these feeders, and while they are harmless, they are annoying. Escaped crickets chirp from behind furniture, hide in dark corners, and occasionally startle household members who did not sign up for sharing their home with loose insects. Minimize escapes by transferring crickets carefully, using containers with secure lids, and feeding in controlled environments. Accept that occasional escapes will happen and that a loose cricket in the house, while irritating, is not a crisis.

Make gut-loading a permanent part of your cricket management rather than something you do only right before feeding day. Crickets that are maintained on quality food from the moment you bring them home carry better nutrition than those gut-loaded for just twenty-four hours. Keep fresh vegetables in the cricket container at all times, replacing them before they dry out or mold. This ongoing gut-loading approach means every cricket is ready to feed whenever you need it, and the overall nutritional quality of your feeder supply improves dramatically.

Develop a calcium dusting routine that becomes automatic rather than something you have to remember to do. Keep your calcium powder, dusting container, and feeding tools together in a designated spot near your reptile enclosures. When dusting becomes part of the physical workflow of preparing food rather than a separate mental step, you are far less likely to skip it during busy days when shortcuts are tempting. Plain calcium for most feedings, calcium with D3 once or twice weekly, and a multivitamin once weekly or biweekly is a standard schedule that works for most insectivorous reptiles.

Rotate crickets with other feeder insects to provide dietary variety that no single feeder species can match alone. Dubia roaches, black soldier fly larvae, silkworms, and hornworms each offer different nutritional profiles, and rotating between them gives your reptile a broader range of nutrients than any one feeder provides exclusively. Crickets can remain the primary feeder if they work well for your animals, but supplementing with other species even occasionally adds nutritional depth to the diet.

Buy crickets from the best source available to you, prioritizing health and gut-load quality over price. Crickets from a specialty reptile supplier that maintains them on quality food are worth more than bargain-priced crickets from a source that keeps them in bare containers with no food. If your only option is pet store crickets, plan to gut-load them at home for at least twenty-four hours before feeding. Online cricket suppliers who ship healthy, well-maintained feeders can be cost-effective when purchased in quantity, and the consistency of quality often justifies the shipping cost.

Crickets remain an excellent feeder insect for most insectivorous and omnivorous reptiles when used properly, and using them properly means three things every single time you feed - gut-load them, dust them with calcium, and offer only what your reptile will eat in one session. These three practices transform crickets from mediocre nutrition into high-quality feeding events, and skipping any one of them compromises the value of the other two. A gut-loaded cricket without calcium dusting still carries an inverted calcium-to-phosphorus ratio. A dusted cricket that was not gut-loaded delivers calcium on the outside but empty calories on the inside. And leftover crickets in the enclosure are potential biters that have lost both their gut-load and their dust. All three practices work together as a system, and the system only produces good results when all three elements are present consistently.

The hassles associated with crickets - noise, smell, die-offs, escapes - are real but manageable with consistent husbandry of your feeder supply. Think of cricket maintenance as an extension of reptile care rather than a separate chore. The ten minutes per day you spend maintaining clean cricket housing, providing fresh gut-load food, and removing dead insects directly impacts the health of every reptile you feed. Keepers who neglect their feeder insects are functionally neglecting their reptiles' nutrition, even if they feed on schedule. A well-maintained cricket supply is quieter, smells less, suffers fewer die-offs, and delivers better nutrition than a neglected one, so the effort pays dividends on multiple fronts simultaneously.

Consider crickets as one component of a varied feeder insect rotation rather than the only insect in your program. While crickets alone can sustain most insectivorous reptiles when properly gut-loaded and supplemented, dietary variety provides a margin of nutritional safety that single-feeder programs lack. If crickets are your primary feeder, try adding dubia roaches, black soldier fly larvae, or silkworms as secondary options offered once or twice per week. Your reptiles will likely show increased feeding enthusiasm for the variety, and the nutritional breadth improves their overall dietary quality. Different feeder insects carry different amino acid profiles, fat contents, and chitin-to-meat ratios that complement each other in ways that repetitive single-species feeding cannot achieve.

Ultimately, the effort you invest in cricket quality directly determines the nutritional return your reptiles receive from eating them. A cricket is a delivery vehicle, and what it delivers depends on how you prepare it. Keepers who gut-load consistently, dust reliably, and feed thoughtfully get exceptional value from one of the most accessible and affordable feeder insects available. Keepers who grab a handful of starving pet store crickets and toss them in the enclosure are going through the motions of feeding without delivering the nutrition their animals need. The difference between these two approaches is not money or special equipment - it is simply the habit of doing it right every time rather than only when it feels convenient.
