Tarantulas are large, hairy spiders belonging to the Theraphosidae family, known for their intimidating appearance but generally docile nature. Found in tropical forests, deserts, and grasslands, they play a crucial role in controlling insect populations. Despite their portrayal in popular media as dangerous, tarantulas are harmless to humans and are often kept as low-maintenance exotic pets.
Typical Tarantula Appearance & Behavior
Tarantulas are large, hairy spiders that can grow between 2.5 to 12 cm in body length, with some having leg spans up to 30 cm. Their bodies are divided into two parts: the cephalothorax, which has their eyes, fangs, and legs, and the abdomen, where they make silk. They are covered in tiny hairs that help them sense vibrations and detect danger. Most tarantulas are brown, black, or gray, but some species have bright colors like blue, orange, or shiny patterns.
Tarantulas are usually quiet and prefer to live alone. They hunt at night by sneaking up on their prey, which often includes insects like crickets and beetles. Bigger tarantulas can even catch small animals like lizards or birds. To protect themselves, some tarantulas kick tiny hairs from their body to irritate attackers, while others raise their front legs and show their fangs to scare off threats. They also grow by molting, where they shed their old skin to get bigger or fix broken parts. Even though they look scary, tarantulas are usually calm and prefer to avoid fights. They only bite if they feel very threatened.
Tarantulas have a surprisingly long lifespan compared to many other spiders. Female tarantulas can live for 20 to 30 years, depending on the species and care, while males have much shorter lives, typically surviving only 3 to 6 years. Males usually die shortly after reaching maturity and mating. Females, on the other hand, continue to molt and grow throughout their lives, which contributes to their longevity
Tarantula Spiders Habitat
Tarantulas are found in a variety of habitats, from rainforests to deserts.
Rainforests: Many species in South America and Southeast Asia live in dense, humid rainforests. Arboreal tarantulas live in trees and shrubs, creating web retreats, while terrestrial species dig burrows or shelter under logs and rocks. The warm, moist environment provides food and moisture.
Deserts and Arid Regions: Species like the Chilean Rose Tarantula live in dry, hot environments. They dig deep burrows to escape heat and remain active at night. These tarantulas can survive without water for long periods.
Grasslands and Scrublands: Tarantulas in areas like Arizona or Africa live in grassy or scrubby landscapes, building burrows or hiding under rocks and debris to avoid predators and extreme weather.
Perfect Habitat for Your Pet Tarantula
Creating the right habitat for a pet tarantula is essential to ensure its health and well-being. Here’s what you’ll need to set up an appropriate habitat for a pet tarantula:
1. Enclosure Size and Type
Size: The enclosure should be at least 3 times the tarantula’s leg span in length and width. For example, a tarantula with a 5-inch leg span would need an enclosure that is at least 15 inches long and wide.
Type: A glass aquarium or plastic terrarium with a secure lid is ideal. It should be tall enough to accommodate vertical space for climbing if you have an arboreal species (tree-dwelling) or provide enough horizontal space for terrestrial species (ground-dwelling).
2. Substrate and Decorations
Terrestrial Species: A substrate like coconut fiber, peat moss, or topsoil should be about 3 to 4 inches deep. It allows the tarantula to dig burrows or create a secure home.
Arboreal Species: Use a shallow substrate with materials like coconut fiber or bark, and ensure there are vertical climbing spaces.
If you have an arboreal species, provide branches, twigs, or bark for climbing. This is important to mimic their natural environment.
3. Temperature and Humidity
Temperature: Maintain the temperature between 75°F and 85°F (24°C to 29°C). Use a heating pad or lamp, but avoid direct heat on the tank.
Humidity: Aim for 60% to 80% humidity for rainforest species, and 40% to 50% for desert species. You can regulate humidity by misting the enclosure or using a shallow water dish.
4. Hiding Places
Shelter: Tarantulas like to feel secure, so provide hiding spots such as rocks, logs, or artificial caves. A small plastic or clay hide works well, especially for burrowing species.
5. Water and Feeding
Water Dish: Always provide a shallow water dish with fresh water. Make sure it's not too deep to prevent the tarantula from drowning.
Feeding: Tarantulas primarily eat live insects, such as crickets, mealworms, or roaches. Offer food 2 to 3 times a week, depending on the tarantula’s size and age.
6. Lighting and Ventilation
Tarantulas do not require direct sunlight or intense lighting. Keep the enclosure in a dimly lit area with a natural day/night cycle. Avoid bright, artificial light, as it can stress the tarantula.
Ensure good ventilation to avoid mold or excessive moisture buildup. Most enclosures come with vent holes, but you can add extra holes if necessary.
7. Cleaning and Maintenance
Regular cleaning of your pet tarantula’s habitat is crucial for its health. Start by removing uneaten food, dead insects, and feces to prevent mold and bacteria growth. Spot clean the enclosure every few weeks by wiping down surfaces with a damp cloth to remove dust and debris. Replace the substrate every 3 to 6 months, or sooner if it becomes soiled or moldy. The water dish should be cleaned weekly and filled with fresh water to keep it free of contaminants. Occasionally, perform a deep clean by removing everything from the enclosure, sanitizing it with mild soap and water, and thoroughly rinsing before setting it up again. Be sure to handle the tarantula gently during cleaning to minimize stress.
Tarantula Diet
As a pet, a tarantula’s diet consists mainly of live insects and other small prey, which mimic its natural hunting habits. Here's a breakdown of what you should feed your pet tarantula:
Insects: The primary diet for pet tarantulas includes crickets, mealworms, roaches, and superworms. These insects provide the necessary protein and nutrients.
Occasional Larger Prey: Depending on the species and size, some tarantulas may eat small lizards, frogs, or even small mice (especially larger species like the Goliath Birdeater).
Pre-killed Food: If live prey is difficult to obtain, you can feed your tarantula pre-killed insects, as long as they are fresh and have not been left for too long.
Feeding Frequency: Juvenile tarantulas need to eat more often—2 to 3 times a week, while adult tarantulas can typically be fed once every 1 to 2 weeks. Overfeeding can lead to obesity or stress, so it’s important to monitor how much food your tarantula consumes.
Water: Always provide a shallow dish of fresh water to ensure hydration, as tarantulas drink from standing water when needed.
Tarantulas can go for long periods without food, particularly during molting or periods of rest.
Tarantula Tank Mates
Tarantulas are solitary creatures and should not be kept with other pets or tarantulas. They are territorial and may become aggressive, leading to fights or injury. Even if housed with other tarantulas of the same species, there’s a high risk of harm. Additionally, keeping them with other animals like reptiles or amphibians is not recommended, as the tarantula may harm or be harmed. It’s best to keep each tarantula in its own enclosure for its safety and well-being.
Common Tarantula Health Issues
Molt Problems: Tarantulas shed their exoskeleton regularly. If a tarantula has difficulty shedding, it can lead to a condition called "molt paralysis", where parts of the exoskeleton are stuck. This can be dangerous if not addressed.
Dehydration: Tarantulas require access to fresh water at all times. If they don't drink enough, they can become dehydrated, leading to lethargy and difficulty molting.
Obesity: Overfeeding can cause obesity in tarantulas. It's essential to monitor their food intake and avoid overfeeding, especially since they can go for long periods without eating.
Parasites: Tarantulas can occasionally get mites or other parasites, which can cause skin irritation and stress. These can be treated with specialized mite treatments.
Fungal or Bacterial Infections: Poor hygiene or excessive humidity can lead to fungal or bacterial infections, particularly in the skin or respiratory system. Symptoms include unusual behavior, lethargy, or signs of infection (e.g., swelling or discharge).
Stress: Tarantulas can become stressed due to handling, loud noises, improper habitat conditions, or tank mates. Stress can lead to health issues like molting problems, loss of appetite, and general lethargy.
Regularly maintaining proper habitat conditions, offering appropriate food, and minimizing stress are essential for preventing these health issues
Fascinating facts about Tarantulas
Tarantulas are fascinating creatures with several unique traits. They are incredibly strong, able to lift prey up to 50% of their body weight. Females can live for 15-30 years, while males typically live 3-5 years. Though venomous, their venom isn’t dangerous to humans and is used to subdue prey. Unlike web-spinning spiders, they use silk for creating retreats, burrows, and draglines. Tarantulas also have sensitive hairs on their bodies that help detect vibrations and danger. When threatened, they can flick irritant hairs at predators. With a slow metabolism, they can survive months without food, and they come in a variety of colors and patterns for camouflage. Most are nocturnal, hunting at night using vibrations and scent to find prey, and they are highly effective hunters, capable of capturing a wide range of prey, including insects, small mammals, and birds.
Tarantulas are truly remarkable creatures, combining strength, longevity, and unique behaviors that make them fascinating to observe and care for. Despite their intimidating appearance, they are generally calm and docile, making them great pets for those willing to meet their specific habitat and dietary needs. Whether found in rainforests, deserts, or grasslands, tarantulas play an important role in their ecosystems by controlling insect populations. By providing them with the right environment and care, you can enjoy the beauty and intrigue of these ancient arachnids in your own home.
