House Gecko: Health, Temperament, Care & Costs

House geckos are small, insect-eating lizards in the Hemidactylus group, most often the common or Mediterranean house gecko in the US pet trade. Adults are usually about 3-5 inches long and weigh only a few grams, with sticky toe pads, large eyes, and a slender body built for climbing glass, walls, and branches. Many are nocturnal, so they are most active after dusk and may spend the day tucked behind cork bark, plants, or background panels.

Temperament is usually shy rather than social. These geckos are better for watching than frequent handling, and they can move fast enough to escape through tiny gaps. Some settle into routine care and will hunt confidently in front of people, but many remain skittish. Because their skin and tail are delicate, rough handling can lead to injury or tail loss. For many pet parents, that means a house gecko is a display reptile first and a hands-on pet second.

Their care needs center on secure housing, climbing space, correct heat and humidity, and a varied insect diet dusted with calcium. Even nocturnal geckos benefit from appropriate UVB exposure in captivity, because UVB supports vitamin D3 production and calcium use. Good husbandry matters as much as food. When temperatures, humidity, lighting, and supplementation are off, health problems can develop quickly in a small reptile.

With steady care, many house geckos can live about 5-10 years in captivity, though lifespan varies by species, source, and husbandry. They are often chosen because the enclosure footprint is modest, but they still need species-appropriate equipment and an exotics veterinarian for routine care and illness checks.

The most common health problems in pet geckos are linked to husbandry. Metabolic bone disease is one of the biggest concerns when calcium intake is low, the calcium-to-phosphorus balance is poor, UVB is missing, or temperatures are not right for digestion. Affected geckos may seem weak, shaky, reluctant to climb, or develop soft jaws, limb deformities, or fractures. In a tiny lizard, these changes can progress fast, so weakness, tremors, or trouble moving should prompt a visit with your vet.

Dysecdysis, or retained shed, is another frequent issue. House geckos need the right humidity and textured surfaces to shed normally. Stuck shed around the toes, tail tip, or eyes can cut off circulation and damage tissue if it is not addressed. Dehydration, low humidity, parasites, and poor nutrition can all play a role. Eye swelling, cloudy retained skin, or swollen toes after a shed cycle are reasons to contact your vet.

Other problems seen in small geckos include intestinal parasites, weight loss from chronic stress, mouth inflammation, skin wounds, and gastrointestinal impaction if loose substrate is swallowed with prey. Female geckos may also have trouble passing eggs. Because house geckos are prey animals, they often hide illness until they are quite sick. Red flags include refusing food for more than several days, rapid weight loss, sunken eyes, lethargy, open-mouth breathing, visible spine or hips, discharge, or repeated falls from climbing surfaces.

See your vet immediately if your gecko cannot stand normally, has a suspected fracture, is having trouble breathing, has severe retained shed on the eyes or toes, or stops eating and becomes weak. Bringing photos of the enclosure, lighting boxes, temperatures, humidity readings, and the exact supplements you use can help your vet find the cause faster.

House geckos are often seen as lower-cost reptiles, but the setup matters more than the animal itself. In the US, the gecko may cost about $15-$60 for common species, while the enclosure, screen top, climbing décor, digital thermometers, hygrometer, heat source, UVB fixture, hides, and feeding tools often bring the initial setup into roughly the $180-$450 range. A more naturalistic bioactive enclosure or larger vertical terrarium can push startup costs to $500 or more.

Monthly care costs are usually moderate but ongoing. Expect about $15-$40 per month for feeder insects, calcium and vitamin supplements, water conditioner if used, and routine substrate or paper changes. Electricity for heat and lighting is often modest, but bulb replacement adds up. UVB bulbs commonly need scheduled replacement even if they still produce visible light, and that can add about $25-$60 every 6-12 months depending on the fixture and bulb type.

Veterinary care is the cost many pet parents underestimate. A routine exotics wellness exam in many US clinics now falls around $80-$150, with fecal testing often adding $30-$70. If your gecko becomes ill, diagnostics and treatment can rise quickly. For example, a sick visit with exam, radiographs, and supportive care may run about $200-$500, while more involved treatment for metabolic bone disease, severe dehydration, egg binding, or trauma can exceed $500-$1,000 depending on hospitalization and medications.

A realistic annual cost range for one healthy house gecko is often about $300-$800 after the enclosure is established, with higher totals if bulbs, emergency care, or habitat upgrades are needed. Conservative planning helps. Setting aside a small reptile emergency fund can make it easier to choose the care option that fits your gecko's needs when something changes.

House geckos are insectivores. In captivity, they do best on a varied menu of appropriately sized live insects rather than one feeder alone. Good staple options may include small crickets, dubia roaches where legal, black soldier fly larvae, and other small soft-bodied feeders. As a rule of thumb, prey should be no wider than the space between your gecko's eyes. Variety helps reduce nutritional gaps and keeps many geckos interested in eating.

Feeder quality matters. Insects should be gut-loaded before feeding so your gecko gets more than empty calories. Calcium supplementation is also important. Many exotics vets recommend plain calcium on most feedings for growing geckos and a balanced vitamin schedule based on the exact diet, UVB setup, and species. Because over-supplementation can also cause problems, it is smart to ask your vet to review your supplement routine instead of guessing.

Most juveniles eat daily or nearly daily, while adults often do well eating every other day or several times a week. Feed in the evening when house geckos are naturally more active. Remove uneaten insects that may stress or bite the gecko. Fresh water should always be available in a shallow dish, and many house geckos also benefit from light misting that supports hydration and normal shedding.

Avoid wild-caught insects from areas that may have pesticides, herbicides, or parasite exposure. Freeze-dried insects are usually less useful as a staple for small geckos because movement helps trigger feeding and moisture content is lower. If your gecko suddenly refuses food, loses weight, or only licks at prey without striking, your vet should check for husbandry problems and illness.

House geckos do not need walks or out-of-enclosure play, but they do need room to climb, hide, and hunt. A taller, escape-proof enclosure with branches, cork bark, ledges, and plant cover encourages normal movement. These geckos are agile vertical climbers, so usable height matters. Rearranging décor occasionally can add enrichment without making the habitat feel exposed.

Because most house geckos are nocturnal, activity peaks after lights dim. You may notice stalking, short bursts of climbing, and active hunting in the evening. That is normal. During the day, many rest in hidden spots. A gecko that never emerges, falls often, or stops climbing may be stressed, weak, too cold, or ill.

Handling is not exercise for this species. In fact, frequent handling can be stressful and may increase escape or injury risk. If your gecko tolerates brief interaction, keep sessions short and low over a soft surface, and never grab the tail. For many pet parents, the best enrichment is a well-designed enclosure, a regular light cycle, and feeding opportunities that let the gecko stalk live prey safely.

Environmental gradients also support healthy activity. When the enclosure offers warmer and cooler areas plus humid and drier zones, your gecko can choose where to rest and when to move. That choice is part of normal reptile behavior and helps support digestion, shedding, and comfort.

Preventive care for a house gecko starts with husbandry. Use accurate digital thermometers and a hygrometer, and check them often. Replace UVB bulbs on schedule, keep the enclosure secure, and clean water and waste regularly. Small reptiles can decline quickly when heat, humidity, or lighting drifts out of range, so routine monitoring is one of the most useful things a pet parent can do.

Plan on an initial exam with an exotics veterinarian soon after bringing your gecko home, then regular wellness visits after that. Annual exams are a practical baseline for many stable adult geckos, though your vet may suggest different timing for juveniles, breeding females, or geckos with past health issues. Fecal testing can help screen for parasites, especially in newly acquired or wild-caught animals.

At home, keep a simple health log with body weight, appetite, shed dates, stool quality, and any behavior changes. A gram scale is helpful because weight loss often shows up before obvious illness. Watch closely during shed cycles for stuck skin on toes, tail tips, and around the eyes. Quarantine any new reptile away from existing pets, and wash hands after handling the gecko, feeders, or enclosure items because reptiles can carry Salmonella.

See your vet sooner if you notice appetite loss, repeated missed sheds, swelling, discharge, weakness, or changes in posture. Early care is often less invasive and more affordable than waiting until a tiny gecko is critically ill.
