Spiderlings or slings are young or baby tarantulas ranging anywhere from .25 inches to 1.5 inches in length depending on how old it might be. The reason why so many people now opt in to buying a spiderling is due to the fact that they are usually a lot cheaper then adults and it is fascinating to watch them grow. As for growth rate, some species are very fast growing while others are extremely slow growing. It is best you chose which species is right for you. If your a beginner tarantula hobbyist we would recommend you start with a 1.5 inches or bigger spiderling. However here are some steps you can take to care for your sling.



Depending on your species of tarantula spiderling it is key to know what enclosure and environment to have for your sling. Some common examples are

  • Terrestrial Tarantulas (Chilean Rosehair, Mexican Redknee, Brazilian Fire Red, etc): Smallest enclosures possible such as small pill jars of different sizes depending on your sling’s size until you can eventually move it into a deli container and eventually a 5 gallon tank (once a juvenile over 2 inches).
  • Arboreal Tarantulas (Pinktoe, Red Slate Ornamental, Pokies, etc): Small enclosure with height such as tall pill jars in different sizes depending on your sling’s size as they do love to climb and be up from the ground. As they get older you can switch them into tall spice jars until big enough to eventually switch to taller terrariums (once a juvenile over 2 inches).

You will find that slings do tend to burrow a lot more then your average tarantula, so be sure to add a extra substrate to the enclosures so they have enough space to do so. It is also important to make sure that each lid of your enclosure have air holes in them to provide your tarantula with adequate air to breathe. Make sure these holes are not big enough to where your sling can escape.



Feeding can be difficult as these spiderlings require much smaller prey then a full grown tarantula. You can crush a small cricket and leave that in their enclosure so they can eat off of it. As they do start to grow a little you can eventually just add smaller insects such as small juvenile or pinhead crickets as well as fruit flies. Once you see your sling getting closer to 1.5 to 2 inches you can start feeding it slightly bigger prey.



Spiderlings that are less than 1.5 inches cannot drink from waterbowls, they will surely drown. It is best to just water the substrate slightly (in which we do recommend eco-earth) or even just put some droplets to rest on top of the substrate or you can simply add a small plant leaf with a couple of water droplets on it. Once your tarantula does grow closer to 2 inches you can use a plastic bottle cap as a water dish in its small enclosure before being able to move to a big water dish. This all should provide plenty of water and humidity for your young tarantula.



For spiderlings just make sure they are kept in a warm room. Being that they are so small it is not recommended to use a heating source on them as this might end up being too hot for their small enclosures. In addition do not place them under direct sunlight as this tends to stress out your tarantula. A room temperature of about 75-85 degrees should be adequate for them. You do not have to worry about light as most tarantulas actually prefer the darkness over light.
