The Dubia cockroach is found in Central and South America, beginning in Costa Rica. It is common from French Guyana and Brazil to Argentina.
Keep your feeder roaches at a minimum temperature of 68 degrees. Dubia Roaches are Tropical Roaches and need to be kept warm. If you want them to breed, keep them warm. Day temperatures between 85 to 95 degrees are preferable. Humidity levels should be mid range. Unless you live in a very dry area of the country, there will be enough humidity at 90 degrees.

Documented specimens have been found in Brazil, Argentina, and Uruguay.
Because they lack developed arolium between their claws, neither adults nor juveniles can climb smooth, vertical surfaces, though juveniles have been known to climb the soft silicone seals in terrariums and the plastic sides of Rubbermaid containers.
Blaptica dubia, the Dubia roach, also known as the orange-spotted cockroach, Guyana spotted cockroach, or Argentinian wood cockroach, is a medium-sized species of cockroach which grows to around 4.0–4.5 cm (1.6–1.8 in). They are sexually dimorphic; adult males have full wings covering their body, while females have only tiny wing stubs, their tegmina (forewings) being around a fourth of their body length.
Is there any advantage to using substrates? See Substrates for Roach Enclosures for common substrates and whether to use them.
Note the male has large wings that go the length of the body and the female does not. Only adult males have wings.
Offer your roaches fresh fruit or vegetables at least once a week. Carrot, apples, oranges, fresh leafy vegetables and fruit are all eagerly accepted. Remove any fruit or vegetables that are not eaten in a day or two to prevent mold. Mold is a threat to your roach colony, so best to feed only what they consume in a short while. Make sure any dry food such as roach diet or cat chow stays dry, easily accomplished if you are not using substrate or misting.
High starch tubers like potatoes and yams are eaten with disdain and seemingly only for their water content.
Adults are dark brown to black with somewhat lighter orange spot/stripe patterning sometimes visible only in bright light. Coloration does differ slightly with environment and diet from one colony to another.
This is not always the case and it is not an 100% accurate. When sexing dubia Roach Nymphs this way you can do get about a 80% accuracy from my experience.
The third question is two part “How long do they live and how many babies do they have”?
Blaptica dubia are ovoviviparous, giving birth to live young, and can give birth to 20 to 40 nymphs per month under favorable conditions.

The first question i usually get when someone buys Dubia roaches is “What do they eat”?
Ideal temperature range is the higher end of a 75–95 °F (24–35 °C) range. They will not breed below 68 °F (20 °C). They will not molt successfully if the humidity is too low. Dubia roaches can tolerate lower humidity than many other roach species. This species of roach will also sequester more water in its body when well fed upon fruits and water will be released at times of stress.

Provide a high protein food such as dry cat food or roach diet at all times. Also try whole grain cereal, baby cereal or fish flake food or pellets. Dubia roaches especially seem to like sweets such as dry breakfast cereal and breads. Food can be placed in the corners directly on the container floor or in a shallow dish.
Part of Dubia roach care and breeding is making sure the roaches get the best food possible because you will be feeding the Dubia roaches to your pet or selling for someone else’s pet. Here is a quick list of things that you may want to feed your Dubia roaches.
In captivity, enclosure humidity is less important than a supply of high moisture foods, negating the need to mist the enclosure at all when compared to some other tropical pet insect species. Captive habitats should be kept clean and dry in order to have fecal droppings dry and not provide a medium for bacterial or fungal growth. Vertically stacked egg crates greatly help in this, as does good airflow.
New born nymph dubia seem to depend on the adults waste for survival.
The forth question that is asked is “Can Dubia Roaches fly”?
Dubia roaches live on average about 16 months to two years. There are many factors involved, but this is their average according to my experience. The females Dubia tend to out live the males by a few months. I currently have a few hundred Dubia Roaches that are just over two years old.
Blaptica Dubia Roaches are scavengers and live off just about anything leftover. If you are not sure if they can eat something, a good way to check is to separate a few and add the questionable food to the test Dubia roaches in a separate container. After a few days if the roaches are fine from eating a new food, chances are it is ok for the rest of Dubia roaches to eat the new food.
Now back to the first thing of keeping adequate air ventilation, you will notice after separating roaches that the adults are sweating do not immediately put them back into the bin. put them aside by some moving air and give them some room to let them settle down and dry off. if you do have high humidity in the bin say above 50% and your egg plates seem like they are not dry. take out the water crystals and put in some carrots and get some cross ventilation going ASAP.

Too much protein in dubia may cause gout and potentially death in a colony and animals that eat them.
Dubia roaches have approximately 15 to 40 babe nymphs on average. They give birth to live nymphs on average every 28 days after they reach adulthood witch is about six to seven months. Adult Dubia roaches will give birth around nine times during their life span.
Blaptica dubia Roaches are easy and reliable breeders. If your adult Dubia Roaches are not producing young, then you are keeping the temperature too low. If roaches die during incomplete molts, then the humidity is too low.
Unlike crickets, roach enclosures do not smell and can be kept clean with a little attention to housekeeping. Sweep or scoop the bottom of the enclosure as required, usually only every few months.
The section below it is a work in progress and is updated frequently.
This species is sexually dimorphic, the adult males have full wings while the adult females have small wing stubs. They are easy to tell apart at a glance. Once the Dubia Roach colony has established, it is recommended to use the extra males as feeders, leaving a ratio of one male to every three females. As the colony matures, the excess males just take up food and space and create more competition for resources with the females. The males do seem to be more short lived than the females.
The females cannot fly, the males on the other hand is a little different story. The urban myths says that male Dubia roaches can not fly. From my experience and research male Dubia roaches can fly but it is very difficult for them. They need a highpoint to take off but once they achieve flight out of the ten that were tested about half went for 30 to 40 feet down and that’s about it.
Some US states do not allow importation by the general public of B. dubia, considered by some as an invasive species. A Florida man was arrested on felony charges in 2011 related to ordering 500 B. dubia over the internet using a doctored permit, typically issued to researchers.
Some background on Blaptica Dubia Roach, they come from Central and South America beginning somewhere around Costa Rica. Dubia roaches are found in mostly places around Brazil and Argentina. Another common name for dubia roaches is orange spotted roach, depending on there diet the dubia roach colony’s can have different colors. Dubia Roaches sexing is very easy to determine when they are adults the mail has wings and the female does not, please see photo below.
It is best to allow your roach colony to become fully established before feeding heavily out of it. Once colonies are well established, you will have roaches of all different sizes to offer lizards and arachnids the exact size they need.
The second question is “What do I keep my Dubia roaches in”?
