Dubia roaches are among the most popular feeder insects for reptiles, amphibians, and other exotic pets. But when it comes to their diet, many questions arise, especially for those who want to ensure their Dubia roaches are healthy and nutritionally beneficial for their pets. One common query is: Can Dubia roaches eat spinach? The answer isn’t as straightforward as you might think. In this blog post, we’ll explore whether spinach is safe and suitable for Dubia roaches, how it affects their health, and what alternatives you might consider.
Feeding Dubia roaches a proper diet is crucial because their nutritional value directly impacts the health of the animals that consume them. Understanding what they can and cannot eat will not only keep your roaches thriving but also ensure they’re an optimal food source for your beloved pets. Let’s dive deeper into this topic.
The Basics of a Dubia Roach Diet

Dubia roaches are highly versatile feeders, consuming a wide variety of fruits, vegetables, and other plant-based foods. In their natural habitat, they forage for organic matter, making them easy to feed in captivity. However, not all foods are created equal when it comes to their nutrition or safety.
A balanced Dubia roach diet typically consists of:
- Fresh fruits and vegetables (e.g., apples, carrots, squash).
- High-quality roach chow (commercially available or homemade).
- Grains and cereals (such as oats or bran).
The goal is to provide a diet that is rich in vitamins, minerals, and moisture while avoiding foods that could harm the roaches or the animals eating them.
Can Dubia Roaches Eat Spinach?
The short answer is yes, Dubia roaches can eat spinach, but there are some important considerations to keep in mind. Spinach is a nutrient-dense leafy green that contains vitamins like A, C, and K, as well as minerals such as calcium and iron. While it may seem like an excellent food choice, there are potential downsides to feeding spinach to Dubia roaches regularly or in large quantities.
The Benefits of Spinach for Dubia Roaches

- Rich in Nutrients: Spinach provides essential vitamins and minerals that can contribute to the overall health of Dubia roaches. These nutrients may also benefit reptiles that consume the roaches as part of their diet.
- Moisture Content: Like most leafy greens, spinach is high in water content, helping to keep roaches hydrated.
- Readily Available: Spinach is an affordable and accessible vegetable, making it a convenient option for many roach keepers.
The Risks of Feeding Spinach to Dubia Roaches
Despite its benefits, spinach has some drawbacks that warrant caution when feeding it to Dubia roaches:
- Oxalates: Spinach contains oxalates, which can bind to calcium and prevent its absorption. This can result in calcium deficiencies, especially for reptiles that rely on calcium-rich feeders to maintain strong bones and overall health.
- Pesticides: Store-bought spinach often contains pesticide residues unless it is organic. These chemicals can harm Dubia roaches and the pets that consume them.
- Short Shelf Life: Spinach wilts and spoils quickly, which can lead to mold or bacterial growth if not removed promptly. Moldy food is harmful to roaches and can spread diseases.
How to Feed Spinach to Dubia Roaches
If you decide to feed spinach to your Dubia roaches, follow these steps to ensure their safety and maximize the benefits:
Step 1: Wash Thoroughly
Always rinse spinach under running water to remove dirt, pesticides, and other contaminants. For added safety, soak the spinach in a mixture of water and vinegar before rinsing it again.
Step 2: Offer in Moderation
Feed spinach sparingly—once every couple of weeks at most. Mixing it with other vegetables like carrots or zucchini can provide variety and balance in their diet.
Step 3: Remove Uneaten Food
Spinach wilts quickly and can become a breeding ground for bacteria and mold. Remove any uneaten spinach from the enclosure within 24 hours to maintain a clean and healthy environment.
Step 4: Pair with Calcium-Rich Foods
To counteract the effects of oxalates, offer calcium-rich foods such as collard greens, kale, or broccoli alongside spinach. This ensures that your roaches and, by extension, your pets, receive sufficient calcium.
Spinach Alternatives for Dubia Roaches
If you’re unsure about feeding spinach to your roaches, there are plenty of other vegetables that are safe, nutritious, and low in oxalates. Some excellent alternatives include:
- Carrots: High in beta-carotene and easy to store.
- Zucchini: Provides hydration and is low in oxalates.
- Squash: Nutrient-dense and readily accepted by Dubia roaches.
- Bell Peppers: Packed with vitamins and antioxidants.
- Collard Greens: A calcium-rich leafy green that is safer than spinach.
By rotating these options, you can ensure your roaches receive a balanced diet without relying too heavily on spinach.
Common Questions About Feeding Dubia Roaches
Can Dubia Roaches Eat Other Leafy Greens?
Yes! Leafy greens like collard greens, mustard greens, and dandelion greens are safe and nutritious options. However, always avoid greens high in oxalates, such as Swiss chard.
Should I Gut-Load Dubia Roaches Before Feeding Them to My Pet?
Absolutely. Gut-loading involves feeding roaches a nutrient-rich diet 24–48 hours before offering them to your pet. This ensures that the roaches provide maximum nutritional value.
What Foods Should I Avoid Feeding Dubia Roaches?
Avoid feeding Dubia roaches foods that are toxic or harmful, including:
- Citrus fruits (e.g., oranges, lemons).
- Onions and garlic.
- Processed foods or sugary items.
- Moldy or spoiled food.
The Verdict: Is Spinach a Good Choice for Dubia Roaches?

While Dubia roaches can eat spinach, it should be offered in moderation and as part of a varied diet. The presence of oxalates makes it less than ideal for regular feeding, especially if your ultimate goal is to provide calcium-rich feeders for your reptiles. Instead, prioritize other vegetables that are safer and more nutritionally balanced.
By carefully selecting what you feed your Dubia roaches, you can ensure their health and improve the quality of nutrition they provide to your pets.
Conclusion
Feeding Dubia roaches a diverse and well-balanced diet is essential for maintaining their health and ensuring they’re a nutritious food source for your reptile or amphibian. While spinach can be part of their diet, it’s important to use it sparingly and pair it with calcium-rich alternatives to counteract its oxalates.
