If your Mexican Red Knee Tarantula (Brachypelma smithi) is not eating, it can be a cause for concern. These spiders are typically robust feeders, and a loss of appetite can indicate various issues. This article explores potential reasons for your tarantula’s lack of appetite and provides detailed information to help you address the problem.
Understanding Mexican Red Knee Tarantulas
Mexican Red Knee Tarantulas are known for their striking appearance and relatively docile nature. They are native to Mexico and are often kept as pets due to their manageable size and low maintenance needs. These tarantulas are typically hardy and have a good appetite, which makes a sudden loss of interest in food particularly noticeable.
Common Reasons for Loss of Appetite
Several factors can lead to a Mexican Red Knee Tarantula not eating. Understanding these factors can help in diagnosing the issue and determining the best course of action. Here are some common reasons:
1. Temperature and Humidity Levels
Temperature Fluctuations
Mexican Red Knee Tarantulas thrive in a specific temperature range. They prefer temperatures between 75°F and 85°F (24°C to 29°C). If the temperature in their enclosure falls outside this range, it can affect their appetite. Low temperatures can slow down their metabolism, causing them to eat less or stop eating altogether.
Humidity Issues
These tarantulas also require appropriate humidity levels to stay healthy. They prefer a relative humidity of around 60% to 70%. If the humidity is too low, it can lead to dehydration and a decreased appetite. Conversely, excessive humidity can cause mold growth, which can affect their health and feeding behavior.
2. Shedding (Molt)
Pre-Molt Stage
Tarantulas undergo periodic molts, where they shed their exoskeleton to grow. Before a molt, a tarantula may exhibit a decreased appetite or stop eating altogether. This is a normal behavior as they prepare for the molt.
Post-Molt Stage
After molting, a tarantula may also refuse food while it waits for its new exoskeleton to harden. During this time, it is crucial to provide a stress-free environment and avoid handling the spider.
3. Stress Factors
Environmental Changes
Changes in the tarantula’s environment, such as relocating to a new enclosure or altering its habitat, can cause stress. Stress can significantly impact feeding behavior, leading to a decreased appetite.
Handling and Interaction
Excessive handling or disturbance can stress your tarantula, making it less likely to eat. Mexican Red Knee Tarantulas are generally tolerant of handling, but it is essential to minimize it during periods of stress or adjustment.
4. Health Issues
Parasites and Diseases
Health issues can also affect a tarantula’s appetite. Parasites, such as mites or worms, can cause discomfort and lead to a lack of interest in food. Diseases affecting the tarantula’s digestive system can also result in reduced feeding.
Internal Problems
Internal health issues, such as infections or gastrointestinal problems, may cause your tarantula to stop eating. If you notice other symptoms, such as lethargy or abnormal behavior, it is essential to consult a veterinarian with experience in arachnids.

5. Inappropriate Food Choices
Food Size and Type
The size and type of food offered can influence a tarantula’s feeding behavior. Ensure that the prey items are appropriately sized for your tarantula. Offering prey that is too large can deter your tarantula from eating.
Food Quality
The quality of the food is also important. Dead or poorly kept prey can be unappealing to your tarantula. Always offer fresh, appropriately sized prey to ensure that it is getting the right nutrition.
6. Age and Growth Stages
Juveniles vs. Adults
Young tarantulas may have different feeding patterns compared to adults. Juvenile tarantulas may eat more frequently and have different dietary needs. As they grow, their feeding habits may change, including periods of reduced appetite.
Mature Adults
Adult tarantulas may also go through phases of reduced appetite. This can be due to various factors, including hormonal changes or seasonal variations.
How to Address Feeding Issues
1. Check and Adjust Temperature and Humidity
Ensure that the temperature and humidity levels in the enclosure are within the recommended range. Use a thermometer and hygrometer to monitor these conditions regularly. Adjust heating and humidity as needed to create an optimal environment for your tarantula.
2. Monitor for Molting
If you suspect that your tarantula is about to molt, refrain from offering food until it has completed the process. Ensure that the enclosure is clean and free of mold or mites that could complicate the molting process.
3. Reduce Stress
Minimize handling and avoid making frequent changes to the tarantula’s environment. Provide a stable and secure habitat to reduce stress and encourage normal feeding behavior.
4. Consult a Veterinarian
If your tarantula continues to refuse food despite addressing environmental and health factors, consult a veterinarian experienced in arachnids. They can perform a thorough examination to diagnose any underlying health issues and recommend appropriate treatment.
5. Offer Appropriate Food
Ensure that the food offered is fresh and appropriately sized for your tarantula. If your tarantula refuses live prey, consider offering pre-killed insects or alternative food sources.
6. Observe and Record
Keep detailed records of your tarantula’s feeding behavior, environmental conditions, and any changes in its health. Observing patterns and documenting these details can help in diagnosing the issue and finding a solution.
Conclusion
A Mexican Red Knee Tarantula refusing to eat can be caused by various factors, including temperature and humidity issues, shedding, stress, health problems, inappropriate food choices, or natural growth stages. By carefully monitoring and adjusting the environmental conditions, reducing stress, and consulting a veterinarian if needed, you can help address your tarantula’s feeding issues and ensure its overall health and well-being.
