How Many Hornworms Should I Feed My Hedgehog?

The Answer

Hedgehogs can eat hornworms, and they often enjoy them as treats or dietary supplements. Offer 1-3 hornworms per feeding, 1-2 times per week as part of a varied insectivorous diet. Hornworms are not a primary feeder or dietary staple for hedgehogs—they're a treat or supplement that adds variety. The soft body of a hornworm is genuinely beneficial for older hedgehogs or those with dental issues, as they're easier to bite and swallow than harder-shelled insects like crickets or mealworms. The high moisture content (approximately 85 percent water) also provides hydration value that can be useful for hedgehogs that don't drink as much water as they should. However, hornworms are lower in protein compared to the insects that form a hedgehog's primary diet, so they should not replace your hedgehog's main feeding items. Hedgehogs are insectivorous mammals with straightforward feeding needs, and treating hornworms as an occasional treat or supplement keeps expectations realistic and feeding simple.

Natural Range and Habitat

African pygmy hedgehogs, the species commonly kept as pets, are native to the savannas, grasslands, and scrubland of West and Central Africa, found from Senegal eastward through countries including Mali, Burkina Faso, Niger, and Nigeria. They inhabit warm, dry environments where they're active primarily at dusk and night. In their native habitat, hedgehogs live in burrows, hollow logs, and under vegetation, emerging at night to forage for insects and other invertebrate prey. The warm African landscape has shaped their physiology and behavior—they're adapted to warm climates and are relatively sensitive to cold. Hedgehogs are solitary foragers that spend their active hours hunting for insects and other small invertebrates. This natural history is crucial to understanding what they need in captivity: a warm environment (typically 72-80 degrees Fahrenheit, sometimes higher), appropriate substrate for burrowing and hiding, and access to a consistent supply of varied insect prey. They need the security of hiding spots to feel safe and reduce stress.

Natural Diet and Feeding Behavior

African pygmy hedgehogs are insectivorous foragers that eat a wide variety of invertebrate prey in the wild. Their diet includes beetles, grasshoppers, crickets, ants, termites, millipedes, earthworms, snails, and other small invertebrates they encounter while foraging through soil and vegetation at night. Hedgehogs are opportunistic hunters that eat whatever invertebrate prey is available in their environment. They root through soil and leaf litter, using their sense of smell to locate food. They're relatively slow, methodical foragers rather than fast pursuit predators, moving systematically through their habitat and investigating every nook and cranny for potential prey. Hedgehogs use their small but powerful teeth and strong jaw muscles to crush and consume hard-shelled insects, extracting nutrition from a diet that's high in chitin (the hard exoskeleton of insects). The natural diet of hedgehogs is varied in both species and size of prey, which is important context for captive feeding decisions. Variety matters for complete nutrition, and individual hedgehogs have preferences for different prey types.

Hedgehogs as Dietary Generalists

Like box turtles, hedgehogs are dietary generalists with broad feeding flexibility. They've evolved to eat whatever insect prey is available in their environment, and they're equally capable of consuming small hard-shelled beetles and soft-bodied caterpillars or larvae. This dietary flexibility means that hedgehogs do well on a varied insectivorous diet that includes multiple feeder-insect species. Hornworms fit naturally into this varied approach. Additionally, hedgehogs have no ontogenetic diet shift like some reptiles do; they remain insectivorous throughout their lives. A juvenile hedgehog eats the same kinds of prey as an adult, simply in smaller quantities due to smaller body size. This consistency makes feeding hedgehogs straightforward—the feeding protocol doesn't need to change with age, though portion sizes do increase as the hedgehog grows. This lack of diet shift is one of the advantages of keeping hedgehogs compared to some other exotic pets.

Primary Diet for Hedgehogs

The foundation of a healthy hedgehog diet should be appropriately-sized insects that form the natural diet: crickets, dubia roaches, mealworms, and larvae like black soldier fly larvae (BSFL) or silkworm larvae. These insects should be gut-loaded before offering—meaning they've been fed a nutritious diet themselves so that when the hedgehog consumes them, it's getting nutritious prey rather than empty chitinous shells. Gut-loading the insects before feeding them to your hedgehog can be done by feeding the insects carrots, dark greens, or commercial gut-load formulations. Feed your hedgehog 10-20 insects per feeding, 5-7 days per week, depending on the individual's size and metabolism. Adult hedgehogs typically weigh around 1-2 pounds and eat roughly equivalent to about 1-2 percent of their body weight in insects daily. This is enough food to maintain body condition without leading to obesity. Variety is important—rotate between different cricket species, roaches, mealworms, and occasional larvae to provide nutritional diversity and prevent dietary boredom. Dust some feedings (roughly 2-3 times per week) with calcium and vitamin supplements formulated for insectivores to ensure complete nutrition.

Where Hornworms Fit

Hornworms should be viewed as an occasional treat or dietary supplement, not a primary feeder. They can be offered 1-2 times per week as part of the varied insectivorous diet, but they shouldn't replace the hedgehog's main feeding items like crickets or roaches. The reason is nutritional: hornworms are lower in protein (approximately 9 percent) compared to crickets and roaches (which are typically 15-20 percent protein or higher). A hedgehog fed primarily on hornworms would receive insufficient protein to maintain muscle mass, body condition, and health. However, as an occasional item mixed into the feeding rotation, hornworms add variety, provide different nutrients and textures, and are relished by many hedgehogs. The high water content can also provide hydration value for hedgehogs that might not drink enough water otherwise. Treat hornworms as you would treat any other supplementary feeder insect—useful in moderation, but not replacing the dietary staples.

Special Benefit for Older Hedgehogs

Hornworms have a particular advantage for aging hedgehogs or those with dental problems. As hedgehogs age, their teeth can wear down, become loose, develop cavities, or develop other issues that make it painful or difficult to bite through hard-shelled insects like crickets or mealworms. A soft-bodied hornworm requires far less jaw force to consume—the hedgehog can bite through the body easily without pain or struggle, and the prey item can be swallowed without difficulty. For an older hedgehog with compromised dentition, regular inclusion of soft prey items like hornworms can make feeding more comfortable and ensure the animal continues eating adequate nutrition despite dental challenges. Additionally, the soft body makes hornworms easier for a hedgehog to handle in its mouth without risk of frustration or injury. If your hedgehog is aging or showing signs of dental problems (difficulty eating, food dropping from mouth, eating only soft foods), increasing the frequency of soft-bodied prey items like hornworms (while reducing very hard-shelled insects) can significantly improve feeding comfort and nutritional intake. However, this doesn't mean abandoning hard-shelled insects entirely—most older hedgehogs can still handle them and benefit from the variety and nutritional profile they offer.

Nutritional Profile

Hornworms have a nutritional composition of approximately 9 percent protein, 3 percent fat, and a calcium-to-phosphorus ratio of roughly 3.07 to 1. The protein content is lower than optimal for a hedgehog's primary diet (insects like crickets and roaches provide 15-20 percent protein or more), but it's adequate as a supplementary item. The fat content at 3 percent is relatively low, which is fine for a supplementary feeder. The calcium-to-phosphorus ratio of 3.07:1 is good, which means you're not introducing an imbalance when feeding hornworms alongside your hedgehog's regular diet. The moisture content of approximately 85 percent is notable—it provides hydration and can be useful for hedgehogs that don't drink as much water as they should or that live in dry environments. However, this hydration benefit shouldn't be relied upon as the sole strategy for maintaining hydration. Provide fresh water daily and monitor your hedgehog's drinking behavior; if water intake is consistently low, offer more hydrating prey items like hornworms more frequently, while continuing to provide water access.

Feeding Guidelines

Offer 1-3 hornworms per feeding, depending on the individual hornworm size and your hedgehog's size. A typical adult hedgehog can handle 2 medium-sized hornworms in a single feeding. Remember that a commercial cup of hornworms contains 20-24 individuals of varying sizes; you can select appropriately sized specimens from each batch. Offer hornworms 1-2 times per week, mixed into your regular feeding rotation. This frequency ensures variety without creating nutritional imbalance or dependence on a single prey type. On other feeding days, offer crickets, roaches, mealworms, larvae, or other primary feeder insects. Some hedgehogs are enthusiastic about hornworms and will consume them immediately; others may ignore them initially. This is normal and doesn't indicate a feeding problem. If your hedgehog consistently refuses hornworms, that's fine—there are plenty of other feeder insects available. Don't force the issue or become concerned about hedgehog not eating a particular type of prey item.

Offering Methods

Hedgehogs typically hunt by searching for and finding prey on their own rather than having prey dropped directly into their mouth. Place hornworms in a shallow dish or scatter them on the substrate of your hedgehog's enclosure, allowing it to forage and find them naturally. This mimics natural foraging behavior and provides enrichment that improves hedgehog welfare. Some hedgehogs respond well to watching their food move and will hunt actively when live prey is offered. Others will simply walk over a hornworm and eat it incidentally while foraging. Both behaviors are normal. Ensure your hedgehog is actively looking for and consuming offered prey within a reasonable timeframe (typically within an hour). Remove any uneaten hornworms after feeding to prevent them from escaping into your enclosure or dying and decomposing in the bedding. Hornworms can climb and move, and a loose hornworm might become a surprise or hazard after you've cleaned the enclosure.

Age Considerations

Juvenile hedgehogs can eat hornworms just as adults can, but portion sizes should be adjusted. A baby hedgehog might only consume one small hornworm, while an adult typically eats 2-3. Juveniles have higher metabolic rates than adults and require feeding more frequently overall—juvenile hedgehogs should be fed daily or nearly daily, while adults can be fed 5-6 times per week. If offering hornworms to a juvenile, include them in the regular daily feeding but don't devote the entire feeding to hornworms. Include variety from a young age: some hornworms on one day, crickets on another, roaches on another, larvae on another. This varied approach from a young age sets the hedgehog up for a flexible, healthy diet throughout its life. Older hedgehogs, as noted earlier, benefit particularly from soft prey items like hornworms as their dentition ages. Increase the frequency of soft-bodied prey items in an aging hedgehog's diet while maintaining overall nutritional adequacy through continued varied feeding.

Signs of Healthy Feeding

A healthy hedgehog maintains a rounded body shape with visible but not exaggerated ribs and a defined waist. You should be able to feel the ribs if you gently palpate the hedgehog's sides, but they shouldn't be prominently visible or showing sharp points. The hedgehog should be alert and active at night (their natural active period). A healthy hedgehog produces regular fecal pellets, typically daily or every other day. If your hedgehog appears to be losing weight, becoming lethargic, showing signs of quilling distress, or showing other signs of illness, check environmental conditions first (temperature should be 72-80 degrees Fahrenheit, humidity appropriate). Ensure the enclosure has adequate hiding spots and isn't too bright or loud. Then consult a veterinarian if problems persist. Feeding refusal in hedgehogs is most commonly related to temperature being too low—hedgehogs have poor appetite in cool environments and may enter a hibernation-like state if kept too cold.

Common Mistakes

One common mistake is feeding hornworms as the primary feeder insect when they're better suited as a supplement. A hedgehog fed primarily on hornworms will receive insufficient protein and may not maintain healthy body condition. Another mistake is offering oversized hornworms to a small hedgehog. Select appropriately sized specimens from each batch. A third mistake is not providing dietary variety. Hedgehogs need varied prey items; relying on a single insect species, even if it's a good one like crickets, can lead to nutritional imbalance and dietary boredom. A fourth mistake is not gut-loading feeder insects. Prey insects should be fed a nutritious diet before being offered to your hedgehog; this dramatically improves the nutritional value your hedgehog receives. A fifth mistake is neglecting calcium and vitamin supplementation. Dust some feedings (typically 2-3 times per week) with calcium supplement formulated for insectivores. Finally, some keepers maintain improper temperature in the enclosure. Hedgehogs are sensitive to temperature and require consistent warmth (72-80 degrees Fahrenheit). A cold hedgehog won't eat well regardless of what prey items are offered, may fail to digest food properly, and may become lethargic or sick.

Gut-Loading Feeder Insects

One of the most important practices for hedgehog health is gut-loading the feeder insects before offering them to your hedgehog. Gut-loading means feeding the insects a nutritious diet before they're consumed, so that when the hedgehog eats them, it's receiving the nutrition from both the insect's body and the nutrition inside the insect's digestive system. Gut-load crickets, roaches, and other feeders with high-quality foods like dark leafy greens, carrots, sweet potato, squash, and commercial gut-load formulations. Feed the insects for 24-48 hours before offering them to your hedgehog. This practice dramatically improves the nutritional value your hedgehog receives from feeder insects. Additionally, gut-loaded insects have better nutritional profiles than starved insects and provide more complete nutrition for growing hedgehogs.

Calcium Supplementation Is Essential

Dust some of your hedgehog's insect feedings (roughly 2-3 times per week) with calcium supplement formulated for insectivores. This is not optional; it's essential for bone health, shell health (if your hedgehog ever develops any shell issues), and long-term health. Calcium deficiency can lead to metabolic bone disease, weakness, and other serious health problems. Calcium supplements are inexpensive, widely available, and simple to use—just dust the insects with powder before offering. Vary the type of supplement slightly if possible (some feedings with calcium, some with calcium+vitamin D, some with multivitamin) to provide nutritional variety, but maintain consistent supplementation.

Enrichment and Foraging Behavior

Hedgehogs are naturally foraging animals, and providing opportunities for foraging behavior is important for their psychological well-being. Rather than simply dumping a pile of insects in the enclosure, scatter them on the substrate or hide them among bedding to encourage natural foraging behavior. This provides enrichment, encourages natural hunting behaviors, and slows feeding so the hedgehog doesn't eat too quickly. Providing foraging opportunities also gives the hedgehog more opportunity to use its instinctive behaviors, which supports psychological health and contentment. A hedgehog that's allowed to forage is often a calmer, more content hedgehog than one fed in a bowl. This natural foraging also mimics what would happen in the wild and provides mental stimulation that keeps captive hedgehogs engaged and satisfied.

Water Intake and Hydration

Hedgehogs should have continuous access to clean water via a water bowl or water bottle. Some hedgehogs are enthusiastic drinkers; others drink very little. Monitor water intake and urine output to gauge hydration status. If your hedgehog drinks very little, offering more hydrating prey items like hornworms (which are 85 percent water) more frequently can help. However, don't rely on hornworms for hydration; ensure your hedgehog has access to water and encourage drinking by keeping the water bowl clean and fresh. Dehydration can lead to metabolic problems and poor digestion, so hydration is important to maintain.

Handling and Socializing

Regular, gentle handling helps hedgehogs become accustomed to human contact and can make them calmer and more docile. However, excessive handling can stress hedgehogs, and some individuals are naturally less tolerant of handling than others. Find the balance for your hedgehog—regular gentle handling that your hedgehog tolerates, without forcing interaction on a stressed animal. Some hedgehogs become excellent pets that enjoy handling; others remain somewhat aloof. Both are normal and healthy. Additionally, avoid handling immediately before or after feeding; allow time for digestion and feeding behavior to occur undisturbed. Respect your hedgehog's individual personality and preferences regarding handling. Stressed hedgehogs may refuse food, so maintaining low stress through appropriate handling practices supports feeding success.

Long-Term Hedgehog Care

African pygmy hedgehogs live 5-8 years in captivity with proper care, sometimes longer. They're a substantial commitment requiring consistent daily feeding, heating, cleaning, and care. Before acquiring a hedgehog, ensure you're prepared for the multi-year commitment and the ongoing costs of feeders, heating, supplements, and potential veterinary care. Hedgehogs can require specialized veterinary care, and regular veterinary checkups are recommended. A well-cared-for hedgehog makes an engaging, rewarding pet, but only if you're prepared for the commitment and expense involved in proper care.

The Bottom Line

Hedgehogs are insectivorous foragers that thrive on a varied diet of insects. Hornworms fit well into this dietary variety as an occasional treat or supplement—offer them 1-2 times per week as part of your hedgehog's regular feeding rotation. Don't make hornworms a dietary staple. The soft body of a hornworm is particularly useful for older hedgehogs with dental issues, making feeding more comfortable. With appropriately varied insectivorous feeding, regular heat, proper hydration, consistent calcium supplementation, and good husbandry, hedgehogs are straightforward and rewarding animals to keep. They're relatively simple to feed compared to more specialized species, and hornworms can be one small part of a healthy, balanced diet. Respect the hedgehog's insectivorous nature, provide variety, and maintain consistency, and you'll have a healthy, long-lived hedgehog.
