Instructions
Have the red tail boas probe sexed, in order to ensure that you have both a male and female snake. Probe sexing is the only really accurate way to determine the gender of a boa constrictor. This method should only be performed by a professional, such as a veterinarian.
Increase the amount of food you're giving to your female boa. Slowly increase the food over a period of about six months. By the time the female is ready to breed, she should look almost fat. Female boas usually don't eat during the period of mating and gestation, so it's best that the female is in a healthy, well-fed condition before breeding.
Begin to adjust the temperature in both the male and female's habitats. In the middle of October, start to aim for a daytime high temperature of about 90 degrees Fahrenheit, and a nighttime low temperature of about 68 degrees Fahrenheit. Adjust the temperature slowly, arriving at these final temperatures in the beginning of December.
Place the male in the female's habitat in the middle of December, a few weeks after the final temperatures have been reached. The temperature change should encourage the boas to begin breeding almost right away. The mating will most likely continue through the rest of December and January.
Remove the male boa from the female boa's habitat at the start of February.
Begin to slowly lower the daytime high temperature and raise the nighttime low temperature. In the middle of March, the temperatures should have been completely adjusted, with a daytime high of the high 80s and a nighttime low in the low 80s. Keep the temperature stable, as temperatures too high or low can cause health problems in the young or the female during this time.
Remove the young snakes from the female boa's habitat as soon as they are born. The female boa could crush her young accidentally. The female boa usually gives birth to anywhere between six and 65 babies after about four to eight months of gestation.
How to Breed Redtail Boas and Morphs
Red tail boas, also known as Colombian boas, are one of the most common boa snakes found as pets. These snakes can be very large, usually growing between 6 and 9 feet long, although some snakes may grow even longer. However, they are known to be relatively calm and docile, especially if they are captive bred. These snakes, like many boas, can be found in a variety of color morphs. These morphs, which are genetic mutations, can create many striking and beautiful colors and patterns on the snake. Since the color morphs are passed on in the genes, you'll need two snakes of the same morph in order to get offspring with that coloration.
