What Red Tarantulas Eat An Overview
Red tarantulas, like other tarantula species, are fascinating creatures with specific dietary needs. Understanding their food preferences and feeding habits is crucial for their health and well-being in captivity. These spiders are opportunistic predators, meaning they will eat a variety of prey items they can overpower. However, providing a balanced and appropriate diet is essential to ensure they thrive. Their diet primarily consists of insects, but there are other food sources that can be offered, taking into consideration factors such as the tarantula’s size, age, and overall health. This guide will provide a comprehensive overview of what red tarantulas eat, ensuring your pet receives the proper nutrition.
Live Insects
The staple diet for red tarantulas comprises live insects, mimicking their natural hunting behavior. Live insects offer the enrichment of the hunt and provide essential nutrients. However, the types of insects you choose to feed your tarantula are important. The insects should be gut-loaded, meaning they’ve been fed a nutritious diet themselves prior to being offered to your spider. This enhances the nutritional value for your pet. Also, make sure the insects are pesticide-free. Several types of live insects can be included in a red tarantula’s diet, but they should always be provided with care, ensuring they are not too large or pose a threat to the tarantula during the hunt.
Crickets

Crickets are a widely available and popular food source for red tarantulas. They are relatively easy to obtain and are often readily accepted by tarantulas. Crickets provide a good source of protein, essential for the growth and maintenance of the spider. However, crickets can be challenging to keep alive, and it’s important to offer only as many as your tarantula can eat in a short time to prevent the crickets from stressing the spider or potentially harming it during a molt. Always gut-load the crickets with nutritious food before offering them to your tarantula, to maximize their nutritional value.
Mealworms
Mealworms are another readily accessible option and are often a favorite of tarantulas. They are relatively easy to care for and store, making them a convenient choice. Mealworms offer a good source of protein and are generally nutritious. However, they have a harder exoskeleton, which may be difficult for younger or smaller tarantulas to digest. It’s best to offer mealworms in moderation. When feeding mealworms, it’s crucial to monitor your tarantula’s feeding habits and adjust the quantity accordingly. As with crickets, gut-load the mealworms to enhance their nutritional profile.
Roaches
Roaches, such as Dubia roaches, are highly nutritious and considered an excellent food source. They are relatively slow-moving, making them easier for the tarantula to catch. Roaches have a high protein content and a favorable calcium-to-phosphorus ratio, crucial for the spider’s health. Roaches can be more expensive and harder to obtain than crickets or mealworms, depending on your location. They are also more likely to burrow, so ensure the tarantula can find and consume them before they disappear. When introducing roaches, ensure they are gut-loaded with a nutritious diet to provide the best nutrients for your red tarantula.
Other Insects

Beyond crickets, mealworms, and roaches, other insects can be incorporated into your red tarantula’s diet to provide variety and additional nutrients. These may include superworms, butterworms, or other commercially available insects. It is important to research the nutritional content and suitability of any new insect type. Consider the insect’s size, potential for defense mechanisms, and ease of digestion for your tarantula. Always source insects from a reputable supplier to ensure they are free of pesticides and diseases. Introduce new insects gradually to observe your tarantula’s acceptance and any potential digestive issues.
Pre-killed Insects
While red tarantulas naturally hunt live prey, pre-killed insects can also be a viable food option, particularly for newly molted spiders or those that are less active. Pre-killed insects eliminate the risk of injury from the prey and make feeding easier. It is important to prepare the insects properly to maintain their nutritional value and avoid any risk of contamination. Offering a pre-killed meal can be a good option for tarantulas that are not actively hunting or have difficulty catching live prey. The quality of the pre-killed insects remains important; they should be gut-loaded before being killed and provided to the tarantula.
Benefits of Pre-killed Insects
Pre-killed insects offer several benefits, including reduced stress on the tarantula and the elimination of potential injuries from live prey. They are particularly useful for feeding juveniles or tarantulas that are molting, as they are less likely to be able to hunt. Pre-killed insects are also a convenient option for owners, as they can be stored and offered as needed. However, it is important to ensure that the insects are fresh and have not been exposed to any harmful substances. Always monitor your tarantula’s feeding response and ensure that it is eating the pre-killed insects readily.
How to Offer Pre-killed Insects

When offering pre-killed insects, it is best to use tongs or forceps to present the food to the tarantula. This allows you to control the feeding process and minimize the risk of the tarantula coming into contact with any potentially harmful elements. Gently wiggle the insect to simulate movement and attract the tarantula’s attention. Remove any uneaten food after a reasonable period to prevent decomposition and maintain a clean enclosure. Always make sure the insect is the right size and type for the tarantula. Provide a variety of insects to keep your tarantula interested and ensure it receives a balanced diet.
Considerations for Insect Size
The size of the insects you feed your red tarantula is a critical factor. Insects that are too large can pose a risk to the tarantula, potentially injuring or even killing it. Insects that are too small will not provide adequate nutrition. As a general rule, the insect should be no larger than the tarantula’s abdomen. Regularly assess the size of your tarantula and adjust the size of the insects accordingly. For spiderlings and juveniles, start with smaller insects, gradually increasing the size as they grow. When in doubt, it is better to err on the side of offering insects that are slightly smaller.
Other Food Sources
While insects are the primary food source, other items can be considered in specific situations. These should be offered sparingly and with caution. It is essential to prioritize the health and well-being of your tarantula and only introduce food items that are safe and beneficial. However, these are not necessary and are not a replacement for a healthy diet of insects, which offer a more complete nutritional profile.
Small Vertebrates

In the wild, tarantulas may occasionally consume small vertebrates such as small lizards or mice. However, offering these as a regular part of a captive red tarantula’s diet is generally not recommended. Small vertebrates can be high in fat and may not provide the same nutritional balance as insects. There is also a risk of introducing parasites or diseases. If you choose to offer a small vertebrate, do so only as an occasional treat and ensure that it is sourced from a reliable, disease-free supplier. Consult an experienced arachnid veterinarian before incorporating any non-insect food into your tarantula’s diet.
Feeding Frequency and Quantity
The feeding frequency and quantity for your red tarantula will depend on its age, size, and individual metabolism. Overfeeding can lead to obesity and health problems, while underfeeding can stunt growth and compromise health. Regular observation of your tarantula and adjusting its feeding schedule accordingly is essential to ensure a healthy diet. Providing the right amount of food is crucial for the spider’s well-being and growth. When in doubt, it’s better to feed slightly less and monitor the spider’s condition.
Factors Affecting Feeding
Several factors influence how often and how much you should feed your red tarantula. Spiderlings, juveniles, and actively growing tarantulas generally require more frequent feeding. As they mature, the feeding frequency can be decreased. Temperature also plays a role, with warmer temperatures typically leading to a higher metabolic rate and increased appetite. Observe your tarantula’s behavior and eating habits to determine the ideal feeding schedule. A tarantula that is not hungry may refuse food and is likely getting sufficient nutrients.
Molting and Feeding

Tarantulas will usually stop eating a few weeks before molting, as they prepare to shed their exoskeleton. This is a normal part of their growth process. Avoid feeding your tarantula during this time to prevent stress and potential complications. After molting, wait a few days for the tarantula’s new exoskeleton to harden before resuming feeding. Offer small amounts of food initially and gradually increase the quantity as it adjusts. Providing a healthy diet post-molt is especially important because the spider will need to rebuild its strength.
Water and Hydration
In addition to a proper diet, providing fresh water is essential for a red tarantula’s health. Always ensure your tarantula has access to a shallow water dish with fresh, clean water. The water should be changed regularly to prevent bacterial growth. Some tarantula keepers also mist the enclosure occasionally to provide additional humidity, which can aid in the molting process. Ensure the enclosure is well-ventilated to prevent mold or excessive moisture buildup. Always provide a source of clean water for your spider.
In conclusion, a well-balanced diet is critical for the health and well-being of a red tarantula. By providing a variety of live insects, offering pre-killed insects when necessary, and understanding the factors that influence feeding, you can ensure your pet thrives. Remember to provide fresh water and monitor your tarantula’s feeding habits and overall health. With proper care and a nutritious diet, your red tarantula can live a long and fulfilling life. Regularly research and stay updated on the best practices for feeding your red tarantula to provide the best care possible.
