If you are allergic to bees or wasps, it’s best to avoid contact. Never hold the spider in front of your face. To the tarantula, hairs are not a delicacy, but instead a defensive weapon. Getting them in your eyes or breathing them can be potentially harmful. Some people get a mild reaction while others get a more intense reaction. It’s a matter of personal preference, which may differ from person to person.

The Housing of Brazilian Black Tarantula

Black tarantulas that are Brazilian are terrestrial species. They are typically longer and wider than other tarantula species. The Brazilian tarantula is an opportunistic burrower and will burrow if given a good substrate. If it doesn’t have a suitable substrate it may start crawling. The mentioned minimum depth for your black tarantula is four inches. To ensure you have a perfect growing medium, use chemical-free potting soil or coco fiber as a growing medium. This species does not have high humidity levels. They are best at between 60 and 75% humidity, and they need a dark room. You can add a water bowl to the terrarium to keep it moist. When it’s time to mist your spiderling enclosure, the water should go on the side of the enclosure, so that your spiderlings can drink and stay hydrated. It is rarely necessary for adults.


Tarantulas should be kept in enclosures no larger than 3 times their leg span. Excessive enclosures can cause falls that can damage or kill your Brazilian black. There are many types of terrariums, aquariums, or enclosures that you can use for your tarantulas. Cross ventilation is more important than ventilation from the top of the tank to make temperature moderate. This can be achieved by making the sides of the enclosure have holes on the sides. A hiding area is essential for a tarantula’s well-being. Many keepers decorate their enclosures with artificial plants and pieces of wood or cork bark to create hiding places. The Brazilian black tarantula is one of the hottest spider species, living in a habitat with temperatures that fluctuate between 65 and 85 degrees F.

Brazilian Black Tarantula Enclosure

There is no ideal room temperature for a tarantula. Some keepers have found they do well in warmer temperatures, while others prefer to keep their tarantulas cool. If your home gets too cold, you can install an electric heater on the bottom or sides of your enclosure. Heat mats on the bottom are also nice, but electric heaters are great because they provide more even heat throughout your home. Use the thermometer in the summer to see what the indoor temperature is. If the temperature gets too high, put a fan on the cool side and the heat sink will help keep the room cooler.

Cleaning of Enclosure

If you want to keep your pet spider healthy and odor free, you should clean its tank regularly. Brazilian black tarantulas aren’t messy creatures. They don’t climb walls, eat paper, or need a lot of attention. However, it is still important to thoroughly clean the tank once a week and to remove any waste or leftover food. Perform a deep cleaning of the enclosure once a month. Deep cleaning your aquarium involves removing the substrate, decorations, and water from the aquarium. Clean the aquarium with soapy water and a soft brush to remove any debris that may have accumulated during the cleaning process. Your skimmer may collect dust from your aquarium as it passes through, so it’s not essential to remove the spider. You need to let the tarantula know that you’re the predator and not the prey. 

When you’re working on deep cleaning jobs, it’s helpful to have an extra clean tank so you can move it into another area when the spider in the everyday tank is finished. Add some food to the temporary tank to make the spider feel more comfortable. The hot water should work fine to clean the tank and decorations of your pet enclosure. If you have stubborn stains in the enclosure that no amount of scrubbing will remove, use a small amount of dish soap. Never use bleach or chemical cleaners, because the fumes will kill your spider.


A healthy diet is essential for Grammostola pulchra. Brazilian black tarantulas are very hearty eaters and will eat anything that they can overpower. For younger tarantulas, smaller food items like pinhead crickets are a good option. To provide a varied diet for your Brazilian black tarantula you can use captive-bred locusts, dubia roaches, mealworms, and live crickets.

Brazilian Black Tarantula handling

Pinky mice or even lizards may also be options, though they should not be offered regularly. There are a couple of arguments against high calcium levels for captive molt diets, but for most reptiles, the level of calcium is not a problem. Be careful when offering your tarantula anything that has been caught from outside. A tarantula can get very sick if a wild animal eats it. Doing so can potentially expose your spider to pesticides or parasites, which can ultimately kill it.


One of the most important parts of an invertebrate’s life cycle, molting, is necessary for growth. Tarantulas usually begin to darken as they prepare to molt before they do so. When your spider becomes sluggish, stops eating, and is hiding, it’s time to put it in its enclosure. It’s important to note these common signs in your black-spotted tarantulas. Its discarded molt may be hard to find. Although your tarantula’s health status will vary from one individual to another, it may be important to monitor your tarantula and give it special care and a feeding routine if you notice symptoms that may indicate it has a molting period. Seek the advice of a vet who knows tarantulas, or maybe even has an experienced keeper who will be able to advise you.

Reproduction and Breeding

The Brazilian Black Tarantula or the American Black Widow is solitary most of the time. They’ll gather for breeding in June through September. When a male is interested in mating, he will go to the female and if she is receptive, he will deposit his sperm into her receptacle under her abdomen. Soon after 2-3 weeks, she will lay more than 600 eggs in a sack that will soon hatch into spiderlings.

The male spider begins by weaving a web from silk, thread, or grass that’s then placed upon a horizontal surface. The spider then rubs its abdomen on the web. It then releases a sticky substance that helps to attach itself to the silk.

The male spider inserts its pedipalps or appendages into the female spider’s genital opening to deposit a spermatophore, a protein. The pedipalps of the tarantula are the same color as the body of the spider. Male and female spiders recognize each other as belonging to the same species. A receptive woman will let down her guard in this initial encounter and exchange of signals and relax into a receptive state. The male inserts his pedipalps into the lower opening of the female’s abdomen, also called the opisthosoma. The female Grammostola pulchra is fiercely guarding her egg sac. The sac should be turned at least once a week to prevent it from becoming misshapen or deformed. She will massage the sac to keep it soft. This is a process that is known as brooding.

The Brazilian black tarantula must be imported with proper documentation to protect it from being illegally traded. If you’re thinking about getting an imported tarantula as a pet, you should make sure your breeder shows you their paperwork before you purchase the animal. A healthy Brazilian black tarantula is essential when buying one. A spider with an unhealthy diet is unlikely to survive much longer than a healthy one. Therefore, it’s important to choose the right type of spider. Make sure it comes from a reputable breeder.

While in captivity, many different kinds of parasites could infest your tarantula’s tank, but it all depends on the specific tank climate When there is excessive humidity and the temperature exceeds 75 degrees F, mites, and worms are usually found on feeder insects that aren’t captive-bred. Treat your pet spider with the appropriate medication depending on the severity of the parasite infestation.

 When you are choosing your first black tarantula, you should know that Brazilian black tarantulas require more ventilation than most tarantulas. Mold in a tank is unhealthy for the spider, so it needs to be removed. If it is not treated promptly, your spider could become sick or die.
