Preparing for Breeding

Breeding tarantulas can be an exciting and rewarding experience for any arachnid enthusiast. However, it is important to be well-prepared before embarking on this journey. Here are some essential steps to take when preparing for tarantula breeding.


First and foremost, it is crucial to do your research before attempting to breed tarantulas. This includes learning about the specific species you plan to breed, their natural habitat, and their breeding habits. It is also important to understand the risks involved and how to minimize them.

Care and Enclosure

Proper care and housing are essential for healthy and happy tarantulas. Make sure your tarantulas are well-fed, have access to clean water, and are housed in a suitable enclosure. The enclosure should be large enough to accommodate both the male and female tarantulas and provide adequate hiding places.

Temperature and Humidity

Tarantulas are sensitive to temperature and humidity changes. Make sure the temperature and humidity levels in the enclosure are appropriate for the species you plan to breed. This information can be found through research or by consulting with a veterinarian or experienced breeder.


The substrate in the enclosure should be appropriate for the species you plan to breed. It should be clean, free of toxins, and provide a suitable environment for the tarantulas to burrow and molt.

Food and Crickets

Feeding your tarantulas a balanced diet is essential for their health and wellbeing. Make sure they have access to a variety of live prey, such as crickets, roaches, and mealworms. It is also important to provide enough food to ensure the female tarantula is well-fed before breeding.

Male Tarantulas

When breeding tarantulas, it is important to have a healthy and mature male tarantula. Make sure the male is well-fed and has not recently molted before introducing him to the female.

Female Tarantulas

Most female tarantulas reach sexual maturity between 3-5 years of age. Make sure the female is well-fed and has not recently molted before breeding. It is also important to monitor her behavior closely during the breeding process to ensure she is not aggressive towards the male.

By following these steps and doing your research, you can increase your chances of a successful tarantula breeding experience.

The Breeding Process

Breeding tarantulas can be a fascinating experience for any arachnid enthusiast. However, it is important to note that tarantulas are solitary creatures, and introducing them to each other can be a risky process. Here are some essential steps to follow to ensure a successful breeding process.

Mating and Courtship

Before breeding, it is essential to ensure that both the male and female tarantulas are mature and healthy. The male tarantula will typically drum against his body with its legs, swaying too and fro, signaling to the female in an act of courtship that he is interested in breeding. The female, if mutually interested, will gesture to the male by tapping her feet at the entrance to her hide.

Sperm Web and Pedipalps

After the courtship process, the male tarantula will deposit a small sperm web on the ground, which he will then transfer to his pedipalps. He will then approach the female, and using his pedipalps, transfer the semen packet into an opening called the opisthosoma in the female’s abdomen.

Receptive Female

It is important to note that not all female tarantulas are receptive to breeding, and introducing an uninterested female to a male tarantula can result in an attack. Female tarantulas are more likely to be receptive to breeding if they have an abundance of food. Therefore, it is essential to feed the female tarantula more food before breeding. A few weeks before you plan to breed her, you need to give her as much food as she wants.

The Mating Process

Once the male has successfully transferred the semen packet, he will quickly leave before the female is no longer welcoming of his presence for mating purposes. After mating, the female will lay eggs within a few weeks, and it is essential to provide her with a suitable environment to lay her eggs.

In conclusion, breeding tarantulas can be a delicate process, and it is essential to take every precaution to ensure a successful breeding process. By following the above steps, you can increase your chances of successfully breeding your tarantulas.

Post Mating Care

After successfully mating your tarantulas, it’s important to provide proper post-mating care to ensure the health and safety of both the female and any potential offspring. Here are some tips to follow:

Remove the Male Tarantula

Once the mating process is complete, it’s essential to remove the male tarantula from the female’s enclosure. Leaving the male in the same enclosure can lead to the female attacking and potentially killing the male.

Provide a Suitable Environment

After mating, the female tarantula may begin to create an egg sac. It’s important to provide a suitable environment for the female to lay her eggs. This can include a burrow or a specially designed container.


Once the eggs are laid, it’s important to monitor the incubation process. The temperature and humidity levels should be kept consistent to ensure healthy development.

Laying Eggs

During the egg-laying process, it’s important to avoid disturbing the female tarantula. Any disturbances can cause stress and potentially harm the eggs.


When examining the female tarantula, it’s essential to look for the presence of spermathecae. This is a small flap with a pinkish color inside and indicates that the female has mated successfully.

Overall, providing proper post-mating care is essential to ensure the health and safety of your tarantulas and any potential offspring. By following these tips, you can increase the chances of a successful breeding experience.

Raising Spiderlings

Breeding tarantulas is an exciting hobby, but it doesn’t stop once the eggs hatch. Raising spiderlings, or slings, can be a challenging but rewarding experience. In this section, I will provide some tips on how to raise spiderlings successfully.


Spiderlings are tiny and fragile, so they need a suitable enclosure. A vial or baby food jar can be a good option for small spiderlings. A 40 dram vial is recommended for a spiderling that is 1″ (25mm) in legspan. The container should have proper ventilation and a secure lid to prevent escapes.


Spiderlings require more frequent feedings than adults. They should be fed small prey items like fruit flies, pinhead crickets, or small mealworms. The prey should be no larger than the spiderling’s opisthosoma (abdomen). Overfeeding can lead to health problems, so it’s essential to monitor the spiderling’s growth and adjust the feeding schedule accordingly.

Temperature and Humidity

Spiderlings require specific temperature and humidity conditions to survive and develop correctly. The ideal temperature range for most tarantula species is between 75-85°F (24-29°C). The humidity level should be kept between 70-80%. A small water dish can help maintain the humidity level.


Spiderlings are fragile and should be handled with care. It’s best to avoid handling them as much as possible, as stress can harm them. If handling is necessary, make sure to do it gently and with clean hands. Use a soft brush or spoon to move them around if needed.


Raising spiderlings can be challenging, and not all of them will survive. Some may fail to molt or develop health problems. It’s essential to monitor them closely and take action if necessary. If a spiderling shows signs of illness or stress, it’s best to consult a veterinarian or an experienced tarantula breeder.

In conclusion, raising spiderlings can be a challenging but rewarding experience. By providing suitable housing, proper feeding, temperature and humidity conditions, and careful handling, you can increase their chances of survival and development.
