Breeding Feeders

Breeding your own feeder insects transforms how you approach nutrition for carnivorous invertebrates like tarantulas, scorpions, mantises, and centipedes. Instead of relying on pet store purchases with uncertain nutritional quality and irregular availability, you maintain control over the entire food chain. Your feeders eat what you provide them, they breed on your schedule, and you always have appropriately sized prey available when your animals need to eat.

This approach matters most for keepers with multiple carnivorous invertebrates or those keeping species that require frequent feeding. Buying crickets or roaches weekly becomes expensive over time, and store-bought feeders often arrive stressed, dehydrated, or poorly nourished from inadequate care. Breeding colonies eliminate these problems while giving you access to every life stage from tiny nymphs for spiderlings to full-grown adults for mature tarantulas. The initial setup requires some investment in containers and heating, but ongoing costs drop dramatically once colonies establish themselves.

The connection between feeder quality and invertebrate health runs deeper than many keepers realize. Your tarantula or scorpion cannot extract nutrients that the feeder never contained in the first place. Starving crickets from a neglected pet store bin pass that nutritional deficit directly to your animals through simple food chain dynamics. Properly maintained breeding colonies fed nutritious diets produce feeders packed with the protein, fats, and vitamins your invertebrates need for growth, molting, and reproduction.

New keepers often wonder whether breeding feeders is worth the effort or if it requires specialized knowledge beyond their current abilities. Questions about smell, escapees, space requirements, and time commitment reflect legitimate concerns that this article addresses directly. The short answer is that most keepers can maintain productive feeder colonies with basic equipment and modest time investment once they understand the fundamentals of colony management.

This guide covers selecting appropriate feeder species for your situation, setting up colonies efficiently, maintaining them without excessive labor, and ensuring the nutritional quality that makes home breeding worthwhile. You will learn how different feeders suit different invertebrates, what equipment you actually need versus what you can improvise, and how to troubleshoot common problems that cause colony crashes before they become serious.

Dubia roaches represent the gold standard for home feeder breeding due to their nutritional content, breeding productivity, and ease of maintenance. These tropical roaches cannot climb smooth surfaces, rarely fly, produce no odor when kept clean, and breed prolifically at warm temperatures. A colony of several hundred adults generates enough offspring to feed most invertebrate collections indefinitely. Dubias pack excellent protein and fat ratios while accepting almost any fruit, vegetable, or grain you offer them. Their slow movement makes them easy to catch and handle during feeding time.

Crickets remain popular despite their drawbacks because many invertebrates prefer them and they mature quickly from egg to adult. Cricket colonies require more attention than roaches since they smell, escape readily, and cannibalize when crowded or hungry. However, their fast breeding cycle means a small starting colony expands rapidly into productive numbers. Crickets work well for keepers who need large quantities of feeders and can tolerate the noise and odor that comes with maintaining them. The chirping of adult males becomes familiar background noise for experienced keepers.

Mealworms and superworms offer easy maintenance with minimal space requirements, breeding slowly but steadily in bins of substrate. These beetle larvae provide high fat content that suits some feeding situations while being less ideal for regular staple feeding due to their tough chitin. Mealworm colonies essentially run themselves in a dark corner, making them excellent backup feeders that require almost no daily attention between occasional feedings and substrate changes. Superworms grow larger and provide more substantial meals for bigger invertebrates.

Gut-loading your feeders before offering them to your invertebrates amplifies their nutritional value dramatically. Whatever your feeders eat becomes part of their nutritional profile within hours of consumption. Providing fresh vegetables, commercial gut-load diets, or nutrient-dense foods like squash and carrots before feeding time ensures your invertebrates receive complete nutrition. Feeders that have been eating cardboard or minimal rations pass little nutrition to predators that consume them, wasting feeding opportunities.

Colony setup requires appropriate containers, heat sources for tropical species, hiding places, food and water sources, and proper ventilation to prevent moisture buildup. Plastic storage bins work well for most species when modified with screen ventilation panels. Heat mats or heat tape maintain the warmth that tropical roaches and crickets need for active breeding. Egg crates provide vertical surface area that increases usable space and reduces stress. Water crystals or fresh vegetables provide moisture without drowning hazards that standing water creates.

Recognizing healthy breeding activity and addressing problems early keeps colonies productive over the long term. Roach colonies show health through visible gravid females, growing nymph populations, and minimal deaths accumulating. Cricket colonies should produce constant chirping from mature males and visible egg-laying by females. Watch for population crashes, excessive deaths, or breeding slowdowns that indicate temperature problems, disease, inadequate food, or overcrowding. Addressing issues promptly prevents total colony failure that forces you to start over.

Tarantulas accept most common feeder insects readily, making them ideal candidates for home-bred prey. A productive dubia colony easily supports dozens of tarantulas across all size ranges since you can offer small nymphs to spiderlings and adult roaches to large terrestrial species. Crickets work equally well for tarantulas, and some keepers maintain both species to offer variety and backup options. Mealworms and superworms serve as supplementary feeders though their hard exoskeletons make them less digestible than softer prey items.

Scorpions share similar dietary flexibility with tarantulas, accepting roaches, crickets, and appropriately sized worms without fuss. The main consideration for scorpion keepers involves matching feeder size to scorpion size since many species struggle with prey that is too large or too small. Breeding colonies that produce multiple size ranges give you flexibility to feed individuals across your collection regardless of their current dimensions. Small feeder nymphs prove especially valuable for feeding juvenile scorpions that cannot handle adult-sized prey.

Mantises present unique feeding requirements since many species prefer flying or highly mobile prey that triggers their hunting response. Crickets generally work better than roaches for mantises because their erratic movement patterns stimulate predatory behavior more effectively. Breeding both feeder types gives you options, and fruit fly cultures provide essential food for newly hatched mantis nymphs that cannot handle larger prey items. A fruit fly culture takes minimal space and produces continuously with basic maintenance.

Centipedes rank among the most aggressive feeders and accept almost any moving prey they can overpower. Large centipede species readily tackle adult roaches and crickets while smaller species need appropriately scaled feeders. The challenge with centipedes lies more in safe feeding practices than feeder selection since centipedes bite defensively and can injure handlers during feeding time. Dropped feeders that establish themselves in the centipede enclosure may also stress or harass the resident animal.

Assassin bugs, vinegaroons, and other predatory invertebrates have varying feeder preferences that often require experimentation to determine. Some species strongly prefer certain feeder types while rejecting others that seem equally appropriate to keepers. Maintaining multiple feeder colonies gives you flexibility to discover what your particular animals prefer and ensures you can always offer something acceptable even if preferences change seasonally or with age.

Starting a feeder colony requires obtaining healthy starter stock from reputable breeders rather than pet stores where animals may carry diseases or parasites. Online sellers specializing in feeder insects typically offer better quality and lower prices than local shops. Order enough individuals to establish genetic diversity and survive initial losses while the colony adapts to your setup. A hundred adult dubias or a few hundred crickets provides a reasonable starting population for most keepers.

Housing arrangements depend on which species you choose and how many feeders you need to produce. Dubias thrive in dark plastic bins with screen ventilation, egg crates for hiding, and heat mat sections maintaining temperatures around 85 to 95 degrees Fahrenheit. Crickets need more ventilation, more frequent cleaning, and slightly cooler temperatures. Mealworms require only a container of wheat bran or oatmeal substrate with occasional vegetable additions for moisture. Scale your setup to your needs rather than building massive colonies before knowing your actual consumption.

Feeding your feeders determines what nutrition they pass to your invertebrates, so provide quality foods consistently. Fresh fruits and vegetables like carrots, squash, apples, and leafy greens supply moisture and nutrients. Dry foods including oatmeal, fish flakes, and commercial gut-load diets add protein and vitamins. Remove uneaten fresh foods before they mold and maintain dry food availability at all times. This gut-loading transforms basic feeders into nutrient-dense meals.

Maintenance schedules vary by species but generally involve cleaning, feeding, and population monitoring. Roach colonies need substrate changes every few months and regular removal of dead individuals. Cricket bins require more frequent cleaning due to waste accumulation and higher mortality rates. Check water sources, food supplies, and heating equipment weekly at minimum. Investing a few minutes daily prevents problems that cause colony crashes.

Harvesting feeders for use involves selecting appropriately sized individuals and sometimes preparing them before offering to your invertebrates. Use feeding tongs to transfer roaches or crickets to enclosures, dust them with calcium powder if supplementing, and remove any uneaten prey after feeding time. Track feeding responses and adjust quantities based on what your animals actually consume rather than arbitrary schedules.

Letting colonies crash through neglect wastes the time and money invested in establishing them. Feeders need consistent food, water, appropriate temperatures, and periodic cleaning regardless of how busy your schedule becomes. A thriving colony can collapse within weeks when deprived of basic care. Setting reminders, establishing routines, and checking colonies briefly each day prevents the gradual decline that culminates in dead containers full of feeders you could have used. Even five minutes of attention prevents most problems.

Overcrowding causes stress, increased mortality, and reduced breeding that undermines colony productivity over time. Roaches and crickets both need adequate space to thrive, and cramming too many individuals into undersized containers creates problems even with excellent care otherwise. Either cull excess population, expand housing, or feed off surplus before overcrowding becomes critical. Watch for signs like increased deaths, reduced breeding, or aggressive behavior that indicates density problems requiring intervention.

Neglecting temperature requirements prevents tropical species from breeding productively or causes outright colony failure during cold weather. Dubias stop breeding below about 75 degrees and may die in sustained cold. Crickets also need warmth for active reproduction and development. Invest in reliable heat sources, monitor temperatures regularly with thermometers, and have backup heating available for equipment failures. The cost of proper heating equipment is trivial compared to replacing crashed colonies and the invertebrates that starve without feeders.

Feeding low-quality diets to your feeders then wondering why your invertebrates seem unhealthy misses the fundamental principle that feeder nutrition directly impacts predator health. Starving feeders on cardboard and water crystals produces nutritionally empty prey that offers calories without vitamins or complete protein. Gut-loading only works when feeders have time to digest nutritious foods before becoming meals. Plan feeding schedules so feeders contain quality nutrition when your invertebrates consume them rather than offering starving insects.

Ignoring early warning signs allows fixable problems to become colony-ending disasters. Unusual smell may indicate excess moisture, mold growth, or dead animals needing removal. Declining populations suggest reproductive failure from temperature problems, nutritional deficits, or disease. Visible parasites like mites require immediate intervention before they overwhelm the colony and spread to other containers. Check colonies attentively and investigate anything unusual rather than assuming problems will resolve themselves without your action.

Breeding your own feeders gives you control over nutrition quality, ensures consistent availability regardless of pet store stock, and reduces long-term costs compared to purchasing feeders regularly from commercial sources. The investment of time and space pays dividends through healthier invertebrates fed on properly nourished prey that you raised yourself under controlled conditions. Once established, colonies require modest maintenance while producing far more feeders than most keepers can use.

Choose feeder species based on what your invertebrates prefer, what you can realistically maintain given your space and schedule, and how much production you actually need. Dubias offer the best combination of nutrition and easy care for most situations and most keepers. Crickets suit keepers who need high volume or whose animals strongly prefer them despite the extra maintenance involved. Maintaining multiple species provides flexibility and backup when one colony struggles unexpectedly or a particular animal rejects its usual feeders.

Gut-loading transforms mediocre feeders into nutritional powerhouses that support invertebrate health far better than starving prey ever could. What your feeders eat directly affects your invertebrates through simple food chain dynamics that pass nutrients upward. Provide fresh vegetables, quality dry foods, and adequate hydration to feeders before using them as food. This simple practice improves your animals without requiring any changes to their direct care and costs almost nothing extra beyond what you would feed to your feeders anyway.

Consistent basic maintenance prevents the crashes that frustrate and discourage keepers who try breeding feeders without establishing reliable routines. Check colonies regularly for signs of trouble, provide adequate food and heat throughout the year, clean when waste accumulates to problematic levels, and watch for warning signs of problems developing. The routine becomes second nature quickly with practice, and the reward is never running out of feeders or paying pet store prices for questionable quality insects. Your carnivorous invertebrates deserve better than starving crickets from a neglected store bin, and home breeding delivers exactly that reliable quality week after week.
