How to use Dubi Chow

Dubi Chow can be offered dry or wet.  The benefit of serving it dry prevents it from spoiling.  The chow can be either offered in a dish or lightly sprinkled on the bottom of the colony floor where it is easily found.  The benefit of serving it wet, is that the food can be easily found (dubi are attracted to moister) and gives them water at the same time.  When served wet, remove any unused food after 24 hours.  Note how much food you are removing and when making the next batch, reduce by this amount.  If all food is gone after 24 hours, you might not be feeding your dubi enough.  Increase next batch.

  

 

 

How to use water crystals

1 oz of water crystals by weight produces 1.8 gallons of “water chunks”.  The absorption is ~178x its weight in water so use plenty of water.  Allow water crystals to sit in container of water for 24 hours before use.  If after 24 hours, there is no “free” water in the container, this means you did not add enough water and the water crystals can take in more water.  Add more water and let sit.  Better to use more water than required for full saturation.  Place on a dish and the roaches will extract the water from the water gel.

Also can be used to keep up the humidity.

You don’t want to use water with your roaches; they can drowned if too deep.

How to care for your dubi

Dubi are very easy to care for and here are some tips.

1)       You only need to remove food that is uneaten over 24 hours.  If it is moldy remove before that. 

2)      There is no need to keep the colony ultra clean.  They like living in their frass (poo) so you only need to remove it if it gets wet (smell ammonia – which is a sign that you have a husbandry issue) or if it gets too deep (1” and below).  Too deep is really not an issue but they won’t go more than an inch or so deep so no point in keeping it that deep.

3)      Keep the colony in a dark place.  If you are using a glass container, tape cardboard so something else on the sides to help keeps the light out.

4)      Keep the colony around 50% humidity.  Above 70% mold will grow.    Not all mold will kill dubi.  We have had mold in containers and in shipping bags that have not been opened for months without any deaths.  I have heard on the internet that mold kills dubi but I have not experienced this.  But you want to keep them as clean as possible as mold could bother your pet.

5)      If adult males have dry wings this is a sign of dehydration, increase water.

Colony construction 

Egg crates need to be vertical.  This helps the frass get deposited at the bottom of the colony but is also prevents the dubi from piling under something.  Dubi do not like the light and will hide from it.  The bigger the bug the more likely it will die if they pile up on each other.  This is not the case with smaller dubi.  It is better to have more egg flat space than not enough for larger dubi. 

Egg flats need to be vertical

Egg flat horizontal not good for big bug so don’t do it.

Small nymphs can pile up without issue

Adult dubi.  A little too crowded

6)      There are several ways to heat a colony.  You can use a infrad bulb or an undertake or side heater.  I prefer under tank heater.  I reptile heat mat can be used for this purpose.  Monitory temperature and make sure it says within the specified range.

7)      Screen the top of the container to provide ventilation without allowing the dubi to get out or other bugs in. 

8)      If nymphs are dead and their skin is crinkly, then they died during molting due to improper humidity.  Increase it.  You can increase it by putting in more water crystals, a wet cloth, moist food, spraying water, etc .  Just make sure you don’t get the frass wet or it will start to smell like ammonia. 

Breeding – keep temperature above 80F and below 90F.  Some people like to run them at higher temperature.

You can store your dubi in a water closet.  Just check the temperature.  This one stays around 85F all the time and is naturally dark.  This is a great spot for a few breeding colonies.

 

Not breeding.  Keep them at room temperature will slow their growth keep them at receiving size for longer.  This is great if you want to buy in bulk and you don’t want your dubi to outgrow your pet.
