The Ultimate Guide to Dubia Roaches: Everything You Need to Know

Introduction

Dubia roaches are a popular feeder insect for reptiles, amphibians, and other small animals. They're known for being nutritious, easy to breed, and relatively low-maintenance. In this comprehensive guide, we'll cover everything you need to know about dubia roaches, from their biology to their care and breeding.

Dubia Roach Biology

Physical Appearance

Dubia roaches are large, flightless insects with a dark brown or black coloration. They have a flattened, oval-shaped body with long antennae and six legs. Adult females are typically larger than males, measuring around 2 inches (5 cm) in length, while males are about 1.5 inches (4 cm) long.

Diet

Dubia roaches are omnivorous and will eat a wide variety of plant and animal matter. Their diet can include fruits, vegetables, grains, animal feed, and even other insects. In captivity, they are often fed a commercial cricket chow or a combination of food sources.

Reproduction

Dubia roaches reproduce sexually. Females lay eggs in egg cases, each containing 20-40 eggs. The egg cases are incubated for 4-6 weeks, after which the nymphs hatch and begin to feed. Nymphs molt several times before reaching maturity, which takes about 6-9 months.

Dubia Roach Care

Enclosure

Dubia roaches can be kept in a variety of enclosures, such as plastic bins, glass tanks, or specialized roach bins. The enclosure should be large enough to provide the roaches with ample space to move around, and it should have a secure lid to prevent escape.

Substrate

The substrate in the enclosure should be deep enough to allow the roaches to burrow and hide. A mixture of peat moss, coconut fiber, and vermiculite is a good choice.

Temperature and Humidity

Dubia roaches thrive in warm, humid environments. The ideal temperature range is 80-90°F (27-32°C), and the humidity level should be around 60-70%.

Food and Water

Dubia roaches should have access to food and water at all times. A commercial cricket chow is a good staple food, and you can supplement their diet with fruits, vegetables, and other treats. Water can be provided in a shallow dish or a water bottle with a drip tip.

Dubia Roach Breeding

Setting Up a Breeding Colony

To establish a breeding colony, you'll need to purchase adult male and female dubia roaches. A good ratio is 1 male to 2-3 females. The roaches can be kept in a breeding enclosure similar to the one used for housing, but it should be equipped with an egg-laying substrate, such as a dampened piece of cardboard or a commercial egg crate.

Egg Care

Once the females have laid their egg cases, you can remove them from the breeding enclosure and incubate them in a separate container. The container should be filled with a moist substrate, and it should be kept at a temperature of 80-90°F (27-32°C). The egg cases will hatch in 4-6 weeks.

Nymph Care

Once the nymphs hatch, they can be transferred to a separate enclosure. They should be fed a diet of commercial cricket chow or a combination of food sources. Nymphs will molt several times before reaching maturity, which takes about 6-9 months.

Common Mistakes to Avoid

Overcrowding

One of the most common mistakes people make when raising dubia roaches is overcrowding. This can lead to stress, disease, and even cannibalism. A good rule of thumb is to keep no more than 100 roaches per square foot of enclosure space.

Insufficient Food and Water

Dubia roaches need access to food and water at all times. If they don't have enough to eat, they may start to eat each other. Make sure to provide a variety of food sources, and check the water dish regularly to ensure it's full.

Improper Temperature and Humidity

Dubia roaches thrive in warm, humid environments. If the temperature or humidity is too low, they may become sluggish and inactive. Make sure to provide a heat source and a humidifier if necessary.

How to: A Step-by-Step Approach

Setting Up an Enclosure

1. Choose a plastic bin, glass tank, or specialized roach bin of the appropriate size.
2. Add a deep layer of substrate to the enclosure, such as a mixture of peat moss, coconut fiber, and vermiculite.
3. Provide a heat source to maintain a temperature of 80-90°F (27-32°C).
4. Add a humidifier to maintain a humidity level of around 60-70%.
5. Place food and water dishes in the enclosure.

Breeding Dubia Roaches

1. Purchase adult male and female dubia roaches in a ratio of 1 male to 2-3 females.
2. Place the roaches in a breeding enclosure similar to the one used for housing, but equip it with an egg-laying substrate.
3. Remove the egg cases once they have been laid and incubate them in a separate container filled with a moist substrate.
4. Keep the egg cases at a temperature of 80-90°F (27-32°C) until they hatch.
5. Transfer the nymphs to a separate enclosure and feed them a diet of commercial cricket chow or a combination of food sources.
