Overview
What is this animal?
- The African house snake is a glossy brown-to-black lamprophiid from sub-Saharan Africa, named for its habit of hunting rodents in and around human dwellings.
- It is not a colubrid like the corn snake or kingsnake, though it fills the same easy-keeper role, and its scales throw a subtle rainbow iridescence under bright light.
- A pale stripe through each eye is its most recognisable field mark.
- Size dimorphism is dramatic in this species, with males topping out around 60-90cm while females reach 90-135cm, so know the sex of the animal you are buying.
- Its defining trait as a captive is an almost mechanical feeding response, and it takes frozen-thawed prey with a reliability that ball pythons simply cannot match.
- Captive-bred animals are inexpensive, widely available, and live 15-20 years.
- This is arguably the best first snake that most beginners have never heard of.
- It stays around corn-snake size or smaller, needs no special humidity regime, and forgives the minor temperature wobbles that panic new keepers.
Temperament
- Adult house snakes are calm, deliberate handlers that rarely bite defensively and almost never musk, which puts them among the most pleasant small snakes to hold.
- They are nocturnal, so evening handling suits their rhythm, and one or two short sessions a week keeps them settled without stressing them.
- Do not handle for 48 hours after a meal.
- Hatchlings are a different animal, being tiny, flighty, and prone to treating everything that moves as either a threat or a mouse.
- This stage passes within months of regular gentle handling, and buyers should treat early nippiness as normal rather than a fault.
- The bites of even a large adult are trivial and bloodless.
- The one behavioural quirk to manage is the feeding response, because a hand that smells of rodent, or simply appears at feeding time, may be struck at enthusiastically.
- Tap-train by touching the snake gently with a hook or paper-towel roll before non-feeding interactions, and open the enclosure with tongs in hand on feeding days.
- This is a food-motivated mistake, not aggression, and it is entirely preventable with routine.
A good fit for
- First-time snake keepers who want feeding to just work
- People put off by ball python fasting stories
- Keepers with limited space for a full-size vivarium
- Budget-conscious keepers, as snake and setup are cheap
- Those wanting a modestly-sized snake, not a large python
Common mistakes to avoid
- Overfeeding, because they act starving at every meal
- Escapes through tiny gaps; lock every lid and vent
- Feeding-response strikes; tap-train and use tongs
- Never cohabit, as they readily eat other snakes
- Females can lay infertile clutches and risk egg-binding
- Hatchlings are tiny, flighty, and briefly nippy
Enclosure
Minimum 4,050 cm² of floor (628 sq in) · 90 × 45 × 45 cm
Must be housed alone. Solitary; house singly
- House an adult in a vivarium of at least 90x45x45cm (36x18x18in), and treat that as a floor, not a target, because these are active nocturnal foragers that use every inch at night.
- A large adult female, which can approach 135cm, does better in a 120x60x45cm (48x24x18in) enclosure, and the extra room costs little once you commit.
- Never cohabit house snakes, as they are opportunistic snake-eaters and a larger female can and will consume a smaller cage-mate.
- Provide a warm-side surface temperature of 31-32C (88-90F) under a thermostat-controlled heat mat or low-wattage overhead, with a cool side of 22-24C (72-75F) and a night-time drop to around 20-22C that this species tolerates well.
- UVB is not required for a nocturnal snake like this, but a low-output 2-5% (Ferguson zone 1) tube is a reasonable modern addition and does no harm.
- Ambient humidity of 40-60% is fine in most homes, with a moss-filled humid hide added during shed rather than misting the whole enclosure.
- Give at least two snug hides, a water bowl, aspen or coco substrate 5cm deep, and some low branches, which they genuinely climb after dark.
- Escape-proofing is the part keepers most often get wrong with this species.
- House snakes have slim heads, real strength for their size, and a talent for finding the one loose vent or sliding-glass gap, so use locking lids or wedges and check every seam before the first night.

Diet
- Feed frozen-thawed mice no wider than the snake's body at its thickest point.
- Hatchlings take a pinky mouse every 5-7 days, growing juveniles a fuzzy or hopper weekly, and adults an appropriately sized adult mouse every 10-14 days.
- Large females handle adult mice easily, while small males may stay on hoppers for life.
- The famous appetite is also the trap, because a house snake will act starving at every opportunity and strike at almost anything warm.
- Obesity from sympathetic overfeeding is the single most common husbandry failure in this species, so feed to a schedule and body condition, not to the begging.
- A healthy house snake is firm and gently rounded, with no visible spine but also no skin folds or segmented, bready look.
- Always offer food with long tongs, never fingers, and never feed live rodents, which this species does not need and which can injure it.
- Fresh water must be available at all times, and expect the snake to soak occasionally before a shed.
Health
- This is a robustly hardy species with few inherent problems when kept warm, dry-ish, and appropriately fed.
- The realistic health risks are obesity from overfeeding, stuck shed when no humid hide is offered, and the standard quarantine issues of mites or respiratory infection in newly acquired animals.
- Quarantine any new snake for 8-12 weeks away from other reptiles.
- Females carry one species-specific caveat, as they are prolific layers and can produce clutches of infertile eggs, called slugs, even when they have never met a male.
- Provide a mature female with a lay box of damp sphagnum and good body condition year-round, and see an exotics vet promptly if she strains, swells, or stops feeding for weeks, since egg-binding is an emergency.
- Repeated laying also drains calcium and body mass, so let a well-used female regain weight before assuming her slim state is normal.
- Wheezing, open-mouth breathing, or bubbly mucus means the enclosure is too cool or too damp and the snake needs a vet, not a wait-and-see period.
- Locate an exotics-competent vet before you buy, and budget for a 15-20 year relationship with them.

Is this urgent?
Most snake worry is about feeding, and most feeding worry is misplaced. Check the guide for this species' normal fast before treating a refusal as illness.
Go now
Open-mouth breathing, bubbles at the nostrils, or an audible whistleGo now. Respiratory infection. Snakes have one functional lung and little reserve.
NowCannot right itself, or holds the head and neck in an unnatural twistGo now. Neurological signs are always urgent in a snake.
NowToday
A regurgitated mealDo not offer food again for at least a fortnight. Check the warm-end temperature today, then call if it happens twice. Usually too cold, handled too soon, or a meal too large. Repeated regurgitation is a different and more serious problem.
TodayRetained eyecaps after a shed, or a ring of stuck shed on the tail tipRaise humidity and provide a damp hide. Call if it is not resolved within a day. Almost always humidity that was too low during the blue phase. A constricting ring costs the tail tip.
TodaySoon
Refusing food for longer than is normal for this speciesLog the refusal and check the species guide. For an adult ball python, a fast of about a month is not in itself a cause for concern, and much longer voluntary fasts are documented. Weigh weekly through it. The weight trend, not the calendar, is what tells you whether a fast matters.
Log it firstThis is general guidance for a healthy adult, not a diagnosis. An exotics vet who knows your animal always overrides it — and the time to find one is before you need one.
Can a african house snake eat that?
Reptile diets split hard by species. An insectivore and a grazing tortoise share almost nothing, so check the species guide as well as this list.
The full list
Never (15)
AlcoholNo safe amount at any body weight on this site.
neverAvocadoPersin. Fatal to many reptiles.
neverCaffeineCoffee, tea and energy drinks. Cardiac and neurological toxicity at tiny doses for an animal this size.
neverChocolateTheobromine and caffeine. Small mammals and reptiles cannot clear either.
neverCitrusToo acidic, and it interferes with calcium absorption.
neverDog or cat foodProtein and vitamin D levels formulated for a mammal. In tortoises it causes irreversible kidney and shell damage.
neverFirefliesLucibufagins. A single firefly has killed adult lizards. This is the most dangerous item on any reptile list and it is the one keepers do not know about.
neverFish caught from the wildThiaminase and parasite risk for turtles and aquatic species.
neverGarlicSame allium toxicity as onion, and more concentrated by weight.
neverIceberg lettuceWater with no nutrition. It fills a reptile up in place of food that would have done something.
neverLeekAllium family. Same mechanism as onion and garlic.
neverOnionOrganosulphur compounds damage red blood cells. The whole allium family is out.
neverRhubarbOxalate load high enough to cause acute kidney injury.

neverWild-caught insectsPesticide residue and parasites, and the identification risk. Captive-bred feeders only.
neverRare treats (1)
WaxwormsVery fatty. Useful for a underweight animal or for medicating, addictive otherwise. One or two, rarely.

Bell pepperSafe, low oxalate, and the colour gets a refuser eating. A few small pieces a few times a week.
occasionalButternut squashWell tolerated and a useful source of vitamin A precursors. Small cubes a few times a week.
occasionalKaleGood calcium, mild goitrogen. Rotate it. Twice a week.
occasionalMealwormsHard chitin shell and a poor calcium ratio. Fine as part of a varied feed, poor as the whole diet. A few, alongside better feeders.
occasionalSpinachOxalates bind dietary calcium, which is the last thing a reptile at risk of metabolic bone disease needs. A very small amount, rarely.
occasionalEveryday foods (6)
Black soldier fly larvaeUnusually high in calcium; one of the few feeders that does not need dusting. Several per feed.
everyday foodCollard greensOne of the best staple greens for herbivorous and omnivorous reptiles. Daily.
everyday foodCricketsA standard feeder. Gut-load them for 24 hours before offering, or you are feeding an empty shell. Sized no wider than the space between the animal's eyes.
everyday foodDandelion greensExcellent calcium-to-phosphorus ratio and readily taken. Pick away from sprayed ground. Daily, for herbivorous species.
everyday foodDubia roachesBetter calcium ratio and more meat per insect than crickets, and they cannot climb glass. Sized to the animal.
everyday foodMustard greensGood calcium ratio; rotate with other greens. Several times a week.
everyday foodThat food is not on our list. Reptile diets are narrower than they look — check the species guide, and ask an exotics vet before offering anything unfamiliar.
Dust feeders with a calcium supplement to the schedule in the species guide. A reptile can be eating well and still be starving of calcium.
What it really costs
Setup, monthly, first year and across a whole life, itemised and with the electricity worked out from the actual wattage. Published figures for the same animal disagree by a factor of four, so the calculator shows ranges rather than picking one.
Bedding and substrate
For snakes the substrate has to hold the right humidity for the shed, and let the animal get fully under it.
Safe
Cypress mulchHolds humidity without going sour quickly. A common default for tropical snakes.
safeAspen shavingsThe classic for colubrids. Excellent for burrowing; replace any patch that gets wet.
safeTopsoil and coco fibre mixBioactive-ready and holds a burrow.
safePaper towel or newspaperQuarantine, feeding response problems, and post-surgery.
safeWith a caveat
Aspen in a high-humidity setupIt moulds. Aspen suits dry-side species; wet species need mulch or soil.
with a caveatNever
Pine and cedarAromatic phenols.
neverSand for species that are not desert animalsAbrasive and dries the skin, causing shed problems.
neverStuck shed and retained eyecaps are usually a humidity failure during the blue phase, not a substrate failure afterwards.
