The Ultimate Guide to House Gecko Care: Keeping Your Tiny Reptilian Friend Happy and Healthy

House geckos, with their endearing appearance and fascinating behaviors, have become increasingly popular pets. Their relatively small size, ease of care, and captivating personalities make them a great option for reptile enthusiasts, especially beginners. However, like any pet, proper care is essential to ensure their health and well-being. This comprehensive guide will provide you with all the information you need to create a thriving environment for your house gecko and keep them happy for years to come.

## I. Understanding House Geckos

Before diving into the specifics of care, it’s crucial to understand the natural history and behaviors of house geckos. This knowledge will inform your decisions regarding their habitat, diet, and overall management.

**A. Natural Habitat and Behavior:**

* **Origin:** House geckos are a cosmopolitan species, meaning they’re found in tropical and subtropical regions worldwide. They are believed to have originated in Southeast Asia and have spread globally through human activity.
* **Habitat:** In the wild, they inhabit a variety of environments, including rainforests, urban areas, and even deserts. They’re often found near human dwellings, taking advantage of artificial light sources that attract insects.
* **Nocturnal:** House geckos are primarily nocturnal, meaning they are most active at night. During the day, they seek shelter in crevices, under rocks, or behind loose bark.
* **Arboreal:** They are arboreal, meaning they spend most of their time climbing on trees, walls, and other vertical surfaces. Their specialized toe pads allow them to grip smooth surfaces with remarkable ease.
* **Social Behavior:** House geckos are generally solitary animals and do not typically thrive in groups, especially if resources are limited. Housing multiple males together can lead to aggression and fighting. Females may be housed together if enough space and hiding spots are provided.

**B. Different Species of House Geckos:**

While the term “house gecko” is often used generically, several species fall under this umbrella. Some of the most commonly kept species include:

* **Mediterranean House Gecko (Hemidactylus turcicus):** These are small, light-colored geckos with granular skin. They are commonly found in the southern United States and the Mediterranean region.
* **Common House Gecko (Hemidactylus frenatus):** This is one of the most widespread species, found in tropical and subtropical regions worldwide. They are typically larger than Mediterranean house geckos and have a more robust build.
* **Asian House Gecko (Hemidactylus platyurus):** Native to Southeast Asia, these geckos are known for their flattened bodies and broad toe pads.

The care requirements for these species are generally similar, but it’s always best to research the specific needs of your gecko to ensure optimal health.

## II. Setting Up the Perfect Habitat

Creating the right environment is the cornerstone of successful house gecko care. This involves providing a suitable enclosure, appropriate temperature and humidity levels, and plenty of hiding places.

**A. Enclosure Size and Type:**

* **Size:** A 10-gallon tank is generally sufficient for a single adult house gecko. For multiple geckos, a larger enclosure (e.g., 20 gallons or larger) is recommended to provide ample space and reduce competition.
* **Type:** Glass tanks or plastic enclosures are both suitable options. Glass tanks offer better visibility and are easier to clean, while plastic enclosures are lighter and more durable. A secure lid is essential to prevent escapes, as house geckos are adept climbers.

**B. Substrate:**

The substrate is the material that lines the bottom of the enclosure. Several options are suitable for house geckos:

* **Paper Towels:** A simple and hygienic option, especially for quarantine or young geckos. Easy to clean and allows for close monitoring of their health.
* **Reptile Carpet:** A reusable and easy-to-clean option. However, it can harbor bacteria if not cleaned regularly.
* **Coconut Fiber (Coco Coir):** A natural substrate that helps maintain humidity. It should be kept slightly moist but not waterlogged.
* **Peat Moss:** Similar to coconut fiber, peat moss helps retain moisture and provides a naturalistic look.
* **Soil/Sand Mix:** A mix of reptile-safe soil and sand can be used to create a more naturalistic environment. Ensure the soil is free of fertilizers and pesticides.

Avoid using substrates like gravel, wood shavings, or cedar chips, as these can be harmful to geckos.

**C. Temperature and Humidity:**

* **Temperature:** House geckos are ectothermic, meaning they rely on external heat sources to regulate their body temperature. Provide a temperature gradient within the enclosure, with a warm side and a cool side.
* **Warm Side:** Aim for a temperature of 85-90°F (29-32°C) on the warm side of the enclosure. This can be achieved using a heat lamp or a ceramic heat emitter.
* **Cool Side:** The cool side of the enclosure should be maintained at 75-80°F (24-27°C).
* **Nighttime Temperature:** At night, the temperature can drop to 70-75°F (21-24°C).
* **Humidity:** House geckos require moderate humidity levels, typically around 50-70%. This can be achieved by misting the enclosure daily with a spray bottle. A hygrometer (humidity gauge) should be used to monitor humidity levels.

**D. Lighting:**

House geckos do not require UVB lighting, unlike some other reptiles. However, providing a low-wattage fluorescent or LED light can help create a natural day/night cycle and improve the overall appearance of the enclosure. If you want to provide UVB lighting, make sure it is a low output UVB bulb (2-5%) and provide plenty of shaded areas for the gecko to escape the light. Excessive UVB can be harmful. They do require a day/night cycle, so either the ambient room lighting, or a low wattage LED or fluorescent bulb will be adequate.

**E. Decor and Hiding Places:**

Providing plenty of hiding places is crucial for the well-being of house geckos. They are naturally shy and reclusive animals, and hiding places provide them with a sense of security.

* **Hides:** Cork bark, rock caves, and commercially available reptile hides are all excellent options.
* **Plants:** Live or artificial plants can add visual appeal to the enclosure and provide additional hiding places. Ensure that live plants are non-toxic to reptiles.
* **Climbing Structures:** Branches, vines, and bamboo poles provide opportunities for climbing and enrichment. Securely attach these structures to the enclosure to prevent them from falling.
* **Water Dish:** A shallow water dish should be provided at all times. Ensure the water is clean and fresh.

## III. Diet and Nutrition

House geckos are insectivores, meaning their diet consists primarily of insects. Providing a varied and nutritious diet is essential for their health and longevity.

**A. Staple Foods:**

* **Crickets:** Crickets are a staple food for house geckos and are readily available at most pet stores. They should be gut-loaded (fed nutritious food) before being offered to your gecko.
* **Mealworms:** Mealworms can be offered as a supplemental food. They are high in fat and should not be the sole source of nutrition.
* **Dubia Roaches:** Dubia roaches are a nutritious and easy-to-breed option. They are also less likely to escape than crickets.
* **Other Insects:** Occasional treats can include waxworms, butterworms, and small silkworms. However, these should be offered sparingly due to their high fat content.

**B. Gut-Loading and Dusting:**

* **Gut-Loading:** Gut-loading involves feeding insects a nutritious diet before offering them to your gecko. This ensures that your gecko receives essential vitamins and minerals.
* **Dusting:** Dusting insects with a calcium and vitamin D3 supplement is crucial for preventing metabolic bone disease, a common health problem in captive reptiles. Dust insects immediately before feeding them to your gecko.

**C. Feeding Schedule:**

* **Adults:** Adult house geckos can be fed every other day. Offer as many insects as they can consume in a 15-minute period.
* **Juveniles:** Young geckos should be fed daily, as they require more nutrients for growth.

**D. Water:**

* Provide a shallow dish of fresh, clean water at all times. Misting the enclosure daily will also provide them with water droplets to drink from the enclosure walls and decorations.

## IV. Handling and Interaction

House geckos are delicate animals and should be handled with care. While they may not be as cuddly as some other pets, they can still be enjoyed and appreciated through observation and gentle interaction.

**A. Handling Techniques:**

* **Gentle Approach:** Approach your gecko slowly and gently. Avoid sudden movements that may startle them.
* **Scooping:** Instead of grabbing your gecko, gently scoop them up from underneath. Support their body with your hand.
* **Short Sessions:** Keep handling sessions short, especially at first. Gradually increase the duration as your gecko becomes more accustomed to being handled.
* **Avoid Tail Grabbing:** Never grab a gecko by the tail, as they can drop it as a defense mechanism. While the tail will regenerate, it’s a stressful experience for the gecko.

**B. Temperament and Behavior:**

* **Shyness:** House geckos are naturally shy animals and may be initially hesitant to be handled. Be patient and consistent with your handling efforts.
* **Escape Artists:** They are skilled escape artists, so always handle them in a secure area.
* **Nocturnal Activity:** They are most active at night, so handling them during the day may be stressful.

**C. Observing Your Gecko:**

Even if you don’t handle your gecko frequently, you can still enjoy observing their behavior. Watch them hunt for insects, climb on the walls of their enclosure, and interact with their environment. This can provide valuable insights into their health and well-being.

## V. Health and Common Problems

Like all pets, house geckos are susceptible to certain health problems. Being aware of these issues and taking preventative measures can help ensure your gecko lives a long and healthy life.

**A. Common Health Issues:**

* **Metabolic Bone Disease (MBD):** This is a common problem in captive reptiles caused by a calcium deficiency. Symptoms include lethargy, muscle tremors, and bone deformities. Prevent MBD by providing a calcium and vitamin D3 supplement.
* **Respiratory Infections:** Respiratory infections can be caused by low temperatures, high humidity, or poor ventilation. Symptoms include wheezing, sneezing, and difficulty breathing. Maintain proper temperature and humidity levels and ensure good ventilation in the enclosure.
* **Parasites:** House geckos can be infected with internal or external parasites. Symptoms include weight loss, diarrhea, and skin irritation. Consult a veterinarian if you suspect your gecko has parasites.
* **Skin Shedding Problems (Dysecdysis):** Problems shedding can be caused by low humidity. Symptoms include retained shed skin, especially around the eyes and toes. Increase humidity levels and provide a humid hide to help your gecko shed properly.
* **Tail Drop:** As mentioned earlier, house geckos can drop their tails as a defense mechanism. While the tail will regenerate, it’s a stressful experience for the gecko and can leave them vulnerable to infection. Avoid grabbing your gecko by the tail.

**B. Signs of a Healthy Gecko:**

* **Alert and Active:** A healthy gecko will be alert and active, especially at night.
* **Healthy Appetite:** They should have a good appetite and readily consume insects.
* **Clear Eyes and Skin:** Their eyes should be clear and bright, and their skin should be free of lesions or parasites.
* **Normal Shedding:** They should shed their skin regularly and completely.
* **Regular Bowel Movements:** They should have regular bowel movements that are appropriately sized and shaped.

**C. Preventative Care:**

* **Quarantine New Arrivals:** Quarantine new geckos for at least 30 days before introducing them to your existing collection. This will help prevent the spread of diseases and parasites.
* **Regular Cleaning:** Clean the enclosure regularly to prevent the buildup of bacteria and parasites. Remove feces and uneaten food daily, and perform a thorough cleaning of the entire enclosure at least once a month.
* **Proper Husbandry:** Maintain proper temperature, humidity, and lighting levels to keep your gecko healthy and prevent health problems.
* **Veterinary Care:** Consult a veterinarian experienced in reptile care if you notice any signs of illness or injury.

## VI. Breeding House Geckos (Advanced)

Breeding house geckos can be a rewarding experience, but it requires a significant commitment of time and resources. It is not recommended for beginner reptile keepers.

**A. Sexing House Geckos:**

* **Males:** Males typically have a bulge at the base of their tail, which is more pronounced than in females. They may also have femoral pores (small holes) on their inner thighs.
* **Females:** Females lack the bulge at the base of their tail and do not have femoral pores.

**B. Breeding Setup:**

* **Ratio:** A breeding group should consist of one male and several females.
* **Enclosure:** Provide a larger enclosure with plenty of hiding places and climbing structures.
* **Nesting Site:** Provide a nesting site for the females to lay their eggs. A plastic container filled with damp vermiculite or coconut fiber works well.

**C. Incubation:**

* **Egg Removal:** Carefully remove the eggs from the nesting site and place them in an incubator.
* **Temperature:** Incubate the eggs at a temperature of 80-85°F (27-29°C).
* **Humidity:** Maintain high humidity levels (70-80%) in the incubator.
* **Hatching:** The eggs will typically hatch in 45-60 days.

**D. Raising Hatchlings:**

* **Enclosure:** Hatchlings can be housed in small plastic containers or small tanks.
* **Feeding:** Feed hatchlings small insects daily. Dust the insects with a calcium and vitamin D3 supplement.
* **Water:** Provide a shallow dish of fresh water.

## VII. Conclusion

House geckos are fascinating and relatively easy-to-care-for pets that can bring joy and enrichment to your life. By providing them with a suitable habitat, a nutritious diet, and proper care, you can ensure that they live long and healthy lives.
