What They Eat

Like all tarantulas, the Green Bottle Blue Tarantula feeding includes crickets, locusts, mealworms, roaches, smaller spiders, and small lizards. Their favourite foods are crickets, grasshoppers, and beetles. They can go without food for several days and during molting, they completely stop eating. In normal circumstances, you can feed them 1-2 times a week.

Their requirement for little to no food makes them easy to take care of. Their food is also cheap! Remember: like all tarantulas, the Green Bottle Blue Tarantula would like to kill its insects. So you could purchase or trap live insects and place them in the terrarium. This activity can keep your Green Bottle Blue Tarantula juvenile quite happy!

Their Lifespan

Female Green Bottle Blue Tarantulas live up to 12 to 14 years while males live between 8 to 10 years.

Provide your pet with a safe and clean glass tank measuring about 45 x 45 x 45 cm minimum. Don’t put too much stuff inside the tank but do provide some hiding places for your pet. Woodchips at the bottom are a good idea as they will give your Green Bottle Blue Tarantula space to burrow.

Keep a small container of water for your GBT to drink and prevent it from drying out. Place the terrarium/tank in a room where the ambient temperature is about 75 and 85 F. The container of water mentioned earlier will also provide moisture and humidity inside the tank. This is important for your GBT to stay healthy and live a long life.

Ideal humidity in the tank needs to be between 60 to 70% which you should measure with a hygrometer. You need not use special lighting but if you keep plants in the tank, you could use LEDs for their optimal growth.

Training and Handling

The Green Bottle Blue Tarantula is a docile but a moody pet. It is shy and does not like too much handling. This is a very delicate creature and if you drop it accidentally, it could break or fracture its exoskeleton and die.

Moreover, Green Bottle Blue Tarantula bite with its urticating hair can cause itching, pain, and swelling. If its hairs accidentally go in your eyes, they could even blind you. So always wash your hands if you touch your Green Bottle Blue Tarantula.

As stated earlier, the Green Bottle Blue Tarantula is a semi-arboreal, New World Tarantula. New world Tarantulas are generally less aggressive and they tend to hide or run or use their urticating hair before biting humans.

This makes them an ideal pet to keep for beginners. Also, the Green Bottle Blue Tarantula venom is not dangerous and will typically cause only mild symptoms like pain, swelling, tingling, etc.

Like most tarantula species, the Green Bottle Blue Tarantula is not easy to breed because the female tends to eat the male. Always observe the two together and if the female appears to threaten the male, remove it and try again later.

Make sure there is plenty of room in the terrarium for both so that the male can easily run away if needed. It is also a good idea to feed the female plenty of crickets before breeding. This way, she’d be too full to harm the male.

Another obstacle in mating is the fact that some females end up eating the egg sacs too. Also, you need to be patient. In some cases, you might have to cohabit the male and female for several weeks, months even, to get successful breeding and a viable egg sac.

A good time to start breeding is when the female is at least 2 to 3 years old. Spring is especially a good time to breed thanks to the increased moisture – which when combined with increased female-feeding – can result in success.


Like all spiders, the Green Bottle Blue Tarantula shows some pre-molting signs as below:

  • Hiding
  • Refusing food
  • Larger abdomen

During the molting phase, you need to do the following:

  • Increase the humidity levels. You can do so by keeping a water dish and refilling it daily.
  • Never keep any insects – especially crickets – at this stage. Your tarantula is very vulnerable and even a cricket could kill it.
  • Try to keep disturbance to a minimum – leave your Green Bottle Blue Tarantula alone at this time.
  • Wait at least for one week before feeding your pet. This will allow its fangs to harden to the right stage.

Special Notes

  • Make sure the temperature in the green bottle blue tarantula enclosure is between 78 and 82 F. If you need to heat the tank, use a ceramic bulb, heating pads, or mats.
  • Clean the tank every 6 months. However, you must avoid removing the substrate because your Green Bottle Blue Tarantula has spent a lot of time making a home it is comfortable in. In fact, experts recommend not to change the substrate for years. Only remove dead insects and bolus.
  • During molting, your tarantula will lay quite still and appear dead. Do not touch it.
  • If you have a small spiderling, do not keep a very deep dish of water – your pet could drown! Instead provide water in a small bottle cap. This is adequate.
