How to Breed Red Tail Boas

Hello everyone below is a quick little step by step process of how to breed red tail boa constrictors.

Snow boa breeding Orangasm Triple het Moonglow

Things you will need:

1) Male red tail boa – at least 14-18 months of age
2) Female red tail boa – at least 3 years of age (we prefer 4 years)
3) Two large tanks or cages with a controllable heat source
4) A rack system for the babies

Note: We always keep our boas in separate enclosures except for when they are breeding.

Step 1

When preparing the male and female boa for the breeding season you want to maintain the warm side of the tank temperatures at 85-90 degrees F and the cool side at 70-75 degrees F. We use under the tank heaters with thermostats to control temperatures in our breeding room.

Step 2

Increase the females food intake starting in June/July by a third or double what she is eating now. Keep in mind that boas will rarely eat during pregnancy.† You don’t want to over feed her and make her fat but you do want to thicken her up a bit. She will need to be in prime shape before and during her pregnancy to ensure her health and the health of her babies.

Step 3

When October comes around its time to start cycling the boas temperatures letting nighttime temperatures on the warm side of the cage drop to 68-75 degrees F and day time temps being around 85-90 degrees F.† This simulates the heating/cooling cycle they would experience in the wild.

Step 4

We usually introduce our males in late December. Keep a close eye on the two when breeding especially during the first few times they are introduced. We like to put a male in the cage with a female for 3-5 hours while keeping an eye on them and if they don’t show any interest will will take the male out and introduce him again about 5-7 days later. We will continue this process until we start to see the male courting the female (getting on top of her and trying to lock there tails). Copulation can last from a few minutes to several hours, and may occur several times over a few week period.

Step 5

Watch the female closely for her ovulation. It will look like she has swallowed a Nerf football, and it will show in the top lower third of her body.† When you see this do not take the male out of the enclosure if he is still courting her. 2-3 weeks after you notice the ovulation the female will have a post ovulation shed (POS), after this shed its time to take the male out.† After the POS the female will be giving birth approximately 100-120 day later.

Step 6

Its now time to bump up your heat and keep the warm side of the cage at an even 80-85 degrees F during the night and day times. It is important for the temperatures to stay consistent during this period as the female will need heat throughout the next 4 months to incubate the babies inside of her. During the first 2 months of the boas pregnancy you can offer her food (1/2 the normal size) but don’t be surprised if she refuses, this is normal.† We do not recommend to offer any food to females the last 6 weeks of gestation as it may cause them to give berth prematurely.

Step 7

Watch for the pre birth waxy stool. 1-2 days before your female gives birth to her young she will drop a pre birth waxy stool. Sometimes if there are a lot of babies inside her she may accidentally let a baby or two slip out with it.

Step 8

Remove the babies and place them in separate enclosures when they are born to ensure their safety. You don’t want them to be accidentally crushed by their mothers weight. The babies will shed 14 days after there birth and will begin eating after there first shed.

    I am getting two boas soon to breed eventually but I’m getting them as babies what size enclosure do you suggest getting for them for when they are full grown I only want to.buy a enclosure once

  2. William says:

    I would recommend getting a 60 to 80 gallon enclosure per snake. The only time you should house your boas together is when you are breeding them. Hope this helps! :-)

  3. Mikey says:

    I need some advise on my family. I have a pair of snow reds and a pair of sunglow reds and need to know what will give them the best inclosure. and the price for them the best they can have.

    • William says:

      How big are they?

      • mikey says:

        Well right now they are little only about foot and a half. But I just want to know how much for the best type of stuff for the future enclosures. I have plenty of money they are just a hobbie, I love snakes and I just want them to be happy lol. And I want babies. But I need prices and Items like units for their temps and such, and where I can get everything I need for them.

        • William says:

          Mikey if you are just getting into boas I would recommend getting the book “Boa Constrictor Manual” I believe its published by AVS Books. I would also recommend doing a bit of research, we have tons of information available on our blog and you can always submit a question to our FAQ section (link below). As far as enclosures go we use a company called Creative Reptile Terrariums located in southern CA to build us our adult enclosures.

            I discovered your blog last week and sratted follow your posts religiously. I have not commented on any blog just yet but I was thinking I would love to. Itís really exciting to actually contribute to a article even if itís only a blog. I really donít know exactly what to write other than I really enjoyed reading through 2 of the articles. Nice articles indeed. I sure will keep visiting your blog weekly. I learned quite a bit from you. Thx!

    I have a 3 and a half year old female columbian red taild boa …I’m looking to purches a mail red…I have to 4 froot by 1foot by 1foot cages and my femail has a bunch of logs and bedding in her cage I was wondering if I should remove it

    • William says:

      Removing the logs is completely up to you. If the boas breed I would leave the logs in as they probably enjoy climbing around on them. You just want to be careful as to how sturdy the logs are because you don’t want them falling on your boas as it could hurt them. What type of male boa are you looking for?

  5. chase says:

    Any kind ..i dont havent really made up my mind but if u now any boa breeders tht would help

  6. chase says:

    Do u have an idea of wat i should get

    • William says:

      It really depends what kind of genetic project you want to work on. We have some cool stuff for snow/moonglow or jaguare double reverse stripe projects.

    ive just got a 3 and a half year old female common boa, shes about 6 and a half feet, i already have a male red tail whos just over 2 years old and about 6ft, i was wondering would it be possible to try start the breeding process now or would it be too late in the year? and whats the feeding process for the male during breeding?

  8. DanL says:

    I am getting to babies and im going to put them in a 40 breeder for about 100 day, the moving them to a 10 foot tank can i house them together?

  9. Steve says:

    HI,
    i just bought a proven pair of red tails and i was wondering would it be alright to try breen them now or would i have to wait till next season, and also what is the feeding routine for the male during breeding?

  10. Markell says:

    what is both male and female live in the same cage what are my chances of off springs.

    • William says:

      Hi Markell,

      There are many other factors at stake. How long have they been living together? Are you cycling temps in the cage? How old are they?

      Over the years I found its better to introduce the male when the female is of breeding size. But anything is possible when breeding boas!

  16. Mark says:

    I have some red tail boas and I think they are the best snake they don’t get outrageously large 10ft max 75 gallon tanks work great excellent eaters dead or live I have 2 regular columbian 1 het for albino and 1 albino not mention I have family with several more redtails I had one very unsuccessful litter last year hoping for better luck this season even though I don’t believe in seasons with captive snakes cause you can regulate temps.

    I have a female 7.5 foot plus, & a male at around 5.5 foot. I got the male for free & not 100 percent sure if they are normals or not. But I threw them together mid December just to give breeding ago, never did anything prior to the joint but female was almost 12 pounds. Anyways, I was wondering how to go about keeping the babies in a ‘rack system.’ Best way for heat? Belly or Back heat? Is Flexwatt alright to use? & how big should I make a rack to house the babies? I think I read they could have anywhere from 10-20 babies? Wanna make sure I have plenty of space given i am lucky enough to have a lot. Also, my female has swollen up & kinda turned shiney(if you would say) & the male has been with her, before doing research I did feed her a large-jumbo rat, which I hope hasn’t caused any problem, it was right after she started to swell up. My last question is when I put them together, she curled up on top of him, & I haven’t actually seen a tail lock, but I have noticed every now & then she will twitch every half a min or so, for a few hours, Is this a good sign as. I haven’t actually been able to see a lock in tails?

    Ps sorry for the long comment, my first time breeding, & it was a last minute idea, didn’t really research much since I got the male right when they should have been introduced.

    • William says:

      Rack systems are great for babies, and Flexwatt is great and easy to set up. When they are babies you can get away with shoebox size tubs for the first 6-8 months. As far as seeing them breed you dont always see the “tale lock” but if she is swelling up she could be ovulating. I would keep them together until the male is not interested in her any more and/or hanging out on the other side of the cage. Keep your temps up and in a few months you could have lots of babies! :-)

      • Johnie says:

        Will a 24 tub rack system be enough for the babies? & alright. I’ve never used Flexwatt, but I know it’s one of the best to use for racks, belly/back heat. They just ate, since my biggest is about to shed, after I will be putting the two back together tomorrow for the last time to see if they continue to do anything. Thanks!
