Even though Javanese Jungle Scorpions are quite difficult to find if you do manage to get one, they are great for newbies because of their ease of handling. Although Javanese Jungle Scorpions can be aggressive, they could also coexist with other scorpions if you want to house more than one. Although they are terrestrial creatures, they may occasionally burrow. They mostly eat insects in the wild.

Similarity to other scorpions:

The Javanese Jungle Scorpion and the Malaysian Forest Scorpion are remarkably similar. In terms of care, both species are considered simple to keep in groups, value the cost, and are suitable for novices. 

Nutritional Requirement:

They can consume a variety of insects because Javanese Jungle Scorpions are insectivorous (some of them are mentioned above). Give them gut-loading insects to eat (more nutritious). Feedings should be scheduled 3 to 5 days apart. Use mealworms as treats occasionally. Being nocturnal, it feeds at night.

Water Dish:

Keep a shallow water dish nearby for drinking water. The water shouldn’t be so deep that a scorpion might drown in it.

Javanese Jungle Scorpion Breeding:

Captive breeding of Javanese Jungle scorpions is common. Babies grow quickly. The average length of a Javanese Jungle Scorplett at six months is 2.5 inches. This is extremely remarkable when compared to other species, like Hadogenes troglodytes, whose scorpletts are less than one-third the size at a similar age. Unlike Asian Forest Scorpions, they are good parents who do not eat their young.

If you want to leave babies with the parenting adult, house them in a 20 gallons long tank. Instead of taking care of each one separately, this is considerably simpler. In addition to feeding her young scorpions and protecting them from underheating or overheating, the mother will also kill prey (which should be at least the size of her claw and not more than one at a time). Juvenile Javanese Jungle Scorpions might be separated, while steadily outgrowing the burrow in which they live with their mother.


Javanese Jungle Scorpions are stocky and will most probably protect themselves with their powerful claws. They also have a stinger with mild venom, similar to that of a honey bee. Additionally, their sting is not lethal to humans.

Javanese Jungle Scorpion Handling:

The sting of the Javanese Jungle Scorpion is quite benign. So handling them fine. Handle them with extreme caution.

Terrarium Requirements of a Javanese Jungle Scorpion:

Depending on the number of scorpions there are, a 2.5 to 20-gallon tank may hold them. The tank should have a lockable lead. Scorpions are excellent escapers and therefore can squeeze via tiny gaps. They also could lift light leads with a loose fit.


They must have a moist substrate of at least 3 inches of potting soil, sterilized earth, vermiculite, or peat moss.


Heterometrus javanensis should be housed in a 55% humidity setting and provided with water to drink from the water bowl.

You will want a hygrometer to effectively maintain the correct humidity levels for your Javanese Jungle scorpion. A hygrometer is a tool used to monitor the tank’s relative humidity.


Javanese Jungle Scorpion needs temperatures between 75°F to 90°F (24-32°C).

There are several devices that can help you reach these conditions. On the market, there are heating pads made specifically for this aim, and they aid in preserving the tank’s steady ambient air temperature. The most effective approach to achieve this is to have many thermometers placed throughout the cage at various heights and places. Temperatures must be constantly monitored and checked at regular intervals. For instance, putting one at substrate level and a second one at the highest position your scorpion can reach.

Lightning and Heating:

Scorpions will hide the whole day long and generally avoid light. Avoid utilizing overhead heating lamps. Use a heat mat. To establish a temperature gradient, put the heat pad on one side of the enclosure. The heat pad shouldn’t be put under the terrarium because it might cause overheating.


Scorpions are quite shy creatures, therefore they need a place to hide where they could feel protected from predators. Use items as you see fit to achieve the goal. For instance, wood and ceramic pieces will be useful.


Every three to four days, clean the leftover food. Every three to four months, completely replace the substrate and clean the enclosure using a disinfectant that is safe for arachnids. You will also have to remove the skin that has shed when your scorpion molts.

Javanese Jungle Scorpion Health:

Similar to other scorpions, they are also hardy and adaptive if given the correct habitat conditions. They become sluggish, have a swollen stomach, and loss of appetite if there is a health problem with them. They might have the following issues:

  • Molting
  • Overfeeding
  • Mite Infestation


Javanese Jungle scorpions are nocturnal, terrestrial, aggressive, and could live with other scorpions. They are very intriguing to keep as pets. But are hard to find in the pet market. These scorpions can live up to 8 years if given the proper environment and taken proper care of. Hope this short care guide about housing a Javanese Jungle Scorpion will be helpful for you.
