Dubia Roach Care Sheet

General info:

Natural Distribution:

Argentina, French Guyana, Brazil

Description:

Scientific Name: Blaptica dubia

Appearance:

Nymphs, young Dubia Roaches, look similar. They go through several growth stages (7) referred to as instars.
Dubia Roaches are a non climbing non flying roach species they cannot climb plastic or glass.
The adults are sexually dimorphic, the adult females look different from the adult males. The males have wings, the females do not. The males can flutter, hop a few inches, but cannot fly any distance.

Size:

1/8th inch when born, females can reach up to 2 5/8 inches males reach 2-2 1/2 inches

Gestation:

One month,
Dubia Roaches are partially ovoviviparous, giving birth to live young after eggs hatch inside the female, and can give birth to 20 to 40 nymphs per month under favorable conditions.

Growth:

Nymphs mature in about 4 - 6 months depending on temperature and food supply.

Lifespan:

16 - 24 months females live a little longer than the males.

Housing:

The best and easiest container to raise Dubia Roaches in is a plastic tub large enough ( 23 in x 15 in x 16 in) to hold several egg crates (12 in x 12 in x 1 ½ in) with 2 in or more space from the top.
18 Gallon Rubermaid Totes or similar plastic container are ideal and usually easy to obtain Amazon-18 Gallon Rubermaid
The lid may be modified to offer ventilation by cutting a 8 in x 8 in hole and covering it with a plastic embroidery mesh Amazon-Pack Darice Mesh Plastic Canvas

Egg Crates:

Pressed egg crates such as are used to hold 18 eggs are best. As mentioned they are 12 in x 12 in x 1 ½ in in size. They may be placed in the tub vertically by leaning them on one another. This provides easy access for the roaches and allows roach waste (frass) to drop to the bottom of the tub.

Substrate:

No substrate is required. Addition of a substrate will make separation of the various sized young difficult.

Temperature:

Dubia Roaches are tropical, thus an optimum temperature is between 75 & 90 F. Cooler temperatures will be tolerated, but will slow down growth. This is fine if you want your feeder Dubia to remain the size at which you purchased them.

Humidity:

40%-50%. A dish of water crystals in the tub will usually provide this humidity.

Food:

a dish of dry ground food should be provided at all times for optimum growth. The food should be moderately high in protein, from 22 - 25%. Nature Zone Roach Bites ™ are ideal. Carrots and other tubers are a treat, but any excess should be removed after 24 hours to prevent mold. Do not place moist foods on the plate with the dry food, as this may cause mold also.

Water:

Water is best given by using water crystals, they do not spill easily and may be placed on a small flat plate as well. Nature Zone Water Bites ™ are pre moistened water crystals and an ideal source of water for Dubias. Moist fruits, oranges, etc. are also a source of water, but should be removed after 24 hours to prevent mold.

Gut Loading:

As with any live food, what is in their gut adds to their nutritional value. Gut loading Dubia Roaches with vitamin and calcium enriched food will add to their nutritional value. They should be offered an enhanced food 24 to 48 hours prior to being fed to your pet. They also may be dusted with calcium or vitamin preparations such as Nature Zone Herp Pro Calcium ™ or Nature Zone Herp Pro Vitamins ™.

Maintenance:

Keep food and water available at all times and clean out the waste as needed. Do not allow the waste to get any deeper then ½ - ¾ of an inch. The baby Dubia will burrow into the waste and should be removed prior to disposing of the waste. Leave some in as the baby Dubia do better when they can feed on their parents waste. It inoculates their digestive tract with beneficial bacteria.
