Setting Up Dubia Roach Breeder Bins.

Jeremy Smith

First thing to consider with setting up a Dubia Roach Breeder Bin is mapping out a plan for the cheapest and best solutions for raising your own colony of Dubia Roaches.

1st The Container: Your container should be a good size but not too bin for the amount of Dubia Roaches you will be adding to it. You will notice if you put few Dubia Roach breeders in too large of a bin that the males and females will have difficulty finding each other and will not breed as quickly as you would like for them to. Also if you using egg flats in your bin you want to be sure the height of the bin you purchase is over 15 inches tall. Egg flats are generally 11.5 inches tall put you want to be sure they cant reach the top of the bin where they could get out. Also look at the sape of the bin. Try to find one that doesn't have ledges at the top that make a step for them to pull themselves out of the bin. Also look to find a bin that more vertical. When bin shopping you will find some bins are almost oval'd so when you put egg flats in there they will keep falling down because they have little or no support. This is annoying and pushes the egg flats inside of each other causing them to leave little room for the roaches to roam. Also just like any other bin you have for your Dubia Roaches, be sure you add proper ventilation to your bin by cutting appropriate sized hole and hot gluing aluminum screen mesh over the holes to prevent other unwanted guests from entering your bins. 

2nd The Temperature: As you may already know Dubai Roaches cannot get under 68 degrees fahrenheit. They may live but they enter a hibernation like state and will not grow or breed. The ideal temperature range for Dubia Roaches is 85 to 95 degrees fahrenheit. There is some speculation to temperature controlling the sex of the Dubia Roaches offspring but this has not been proven. Dubia Roaches do tend to grow at an accelerate rate with higher temperatures. So if your breeder bin is in the same room as your nymphs, you may want this warmer in that temperature range to be sure your roaches mature more quickly. Your Dubia Roaches will breed in temperature under 85 degrees if you cannot find ways to get their bin temperature warmer. The downside to doing this is that the Dubia Roaches may not breed as quickly as their full potential could be.

3rd The Bin Layout: You want to be sure your roaches have every square inch possible in the bin you select for them. You should have egg flats stacked across 100% of the bin incase and adult Dubia Roach flips on top their back so they can flip back over. This is the only downfall when using plastic containers as breeder bins because the adults could get stuck on their backs and die if they don't have something to help them flip back over. You also want the egg flats or egg crates stacked high as you can get them to give them plenty of room to get around. You have to keep in mind their will be several adult males in one bin that may cause them to be competitive with one another and may even harass the females some which could irritate them and cause them to abort their babies early not allowing them to be born. This will slow your breeder bin down if this is not done properly.

4th Adult Dubia Roaches: When selecting your breeders you can be a little picking to find the best looking ones to use for your breeders. But the most important thing to think about is male to female ratio. Too many males means the females will be harassed and will not give birth as frequently as they normally would be able to. Too few females means all your females will not have a mate to fertilize her eggs she carries. The proper ration should be 1 Male Dubia Roach to every 5 Female Dubia Roaches (1:5). Failure to do this will just be a waste of potential male feeders as they will compete and kill each other anyways, and the females will be overly harassed not producing the most they are fully capable of.

5th Food & Water: Although you can get away with not watering your Dubia Roaches by just simply adding fruits and vegetables to your bins and as the Dubia Roaches feed they get all the necessary moisture they need, this is not the best choice when you are setting up a breeders bin. You should invest in some water crystals to keep moisture readily available to your Dubia Roaches after all, this will be your replenishing supply of Dubia Roaches. These water crystals should be in a container of some sort in your bin thats climbable for your Dubia Roaches. You can scratch containers up with some 60 grit sandpaper  to make a container climbable for them. You also want your feed to always be available for breeders. If a female is too stressed about not having enough feed available she will abort her eggs and the babies will not be born. It also helps if you make your feed ground into a powder to make it as easy as possible for them to eat. As mentioned before the females can easily get stressed about food and water being available causing them to not carry through with their pregnancy. You should also add fresh fruits and vegetables at least twice a week to mix up their diet and help them to have all the necessary vitamins that are required for breeders.

6th Care: You will want to clean this bin out monthly minimum. If you have a small breeder bin with just a few few adult breeder Dubia Roaches (50-200) you can get away with cleaning it monthly but generally you need to do this weekly or bi-weekly. The purpose of cleaning the adult bin out is to manage the health of your breeder, count and replenish dead (adequately adjust male/female ratio), and to remove the new baby nymphs. As mentioned in one of our other blog's, Adult Female Dubia Roaches will protect their young. So instead of going out and breeding again right after giving birth, they will instead protect their current young until they are about 1/4 inch in size. This slows your reproduction rate and can actually throw off your male/female ration as this female will not want anything to do with a male. The baby nymphs will also wander around harassing the pregnant females which can stress them out and cause them to abort their pregnancy early which lowers your reproduction rate. The babies should be stored in a grower or feeder bin until they also become adult Dubia Roaches.
