Why Are My Dubia Roaches Dying? Understanding and Mitigating Roach Mortality

Hello, fellow bug enthusiasts, and welcome back to our Better Than Crickets blog. We know that many of you are devoted breeders, keepers, or aficionados of the wonderful world of insects, and today, we're going to dig into a topic that's been causing some concern for our fellow dubia roach keepers: high mortality rates. If you've been noticing an alarming number of your dubia roaches meeting an untimely end, this post will help you understand why this might be happening and offer practical tips to reduce these unfortunate events.

Understanding Dubia Roach Requirements

Dubia roaches (Blaptica dubia) are among the most popular feeder insects due to their high protein content and easy-to-digest exoskeleton. They're generally hardy and easy to breed, but like any living creature, they have specific environmental and dietary needs. If these are not adequately met, you may witness higher mortality rates.

1. Inadequate Temperature and Humidity

Dubia roaches are tropical insects originally from Central and South America. They thrive in a warm, humid environment. An ambient temperature of 75-85°F and a humidity level around 40% are ideal for their survival and reproduction.

If your roaches are dying, check your temperature and humidity controls. Temperatures under 70°F and over 95°F can potentially be fatal. Cold, dry environments can cause significant stress to Dubia roaches, potentially leading to death. Similarly, overly hot or humid conditions can encourage the growth of mold and harmful bacteria, which can also be fatal.

2. Poor Nutrition

Dubia roaches are not picky eaters, but a balanced diet is essential for their survival. They thrive on a variety of fruits, vegetables, and grains to get all their necessary nutrients. If your roaches' diet is deficient in protein, carbohydrates, or fats, it can lead to their death. Not feeding them often enough, or not offering an adequate hydration source can be detrimental to their overall success. 

Remember, the health of your roaches directly impacts the health of the animals you feed them to. Always aim to provide a nutritious diet, sometimes referred to as gut loading, to ensure both your roaches and your pets are getting the nutrition they need.

3. Inadequate Ventilation

While dubia roaches enjoy a humid environment, that doesn't mean they can survive without fresh air. Poorly ventilated enclosures can lead to a buildup of harmful gases and promote the growth of mold and bacteria. Always ensure your roach colonies have plenty of ventilation to provide fresh air and prevent moisture buildup. I symptom of bad air quality is moisture build up on the walls of the enclosure, when you see this, it is important to increase ventilation.

4. Overcrowding

Though Dubia roaches are communal insects, overcrowding can still cause significant problems. Overpopulation can lead to competition for food, rapid depletion of resources, buildup of harmful gasses and faster spread of diseases. Make sure your colonies have enough space and food to prevent stress and disease transmission.

5. Age

Dubia roaches might live up to 2 years, but it doesn't happen a lot. If they're kept warm and bred all their lives, they live less. Usually, they're adults for about 6-9 months when used for breeding. Some live longer, and others die sooner. If you've got a lot of older Dubia roaches, it's normal for some to die. So, it's good to always have new adults ready to take over from the old ones.

6. Pathogens and Pests

Dubia roaches are generally robust, but they can still fall prey to predators, and other pathogens. Regular inspection of your colonies can help you spot early signs of infestations or diseases and take appropriate actions. Learn more about pests and predators in our blog here - Pests and Predators in a Dubia Roach Colony. Try to maintain a cleaning schedule where you remove dead bodies, this slows the spread of pathogens.

In summary, while it's not unusual to witness some mortality in your Dubia roach colonies, high death rates can indicate underlying problems with their care and environment. Regularly checking your temperature, humidity, ventilation, and population density, alongside providing a balanced diet and ensuring your colonies are free from diseases or pests, can significantly improve the survival rates of your roaches.

Always remember, a healthy roach colony leads to healthy, well-fed pets.
