How Long Does It Take a Mexican Red Knee Tarantula to Mature?
After a spiderling hatches from the egg sac, it typically spends about two weeks in the burrow. After this time, it leaves its home to be independent and find its own way in life. This is, on average, around twelve to sixteen days of age.
It isn’t until the male spiders reach about 4 years of age that they become sexually mature. At this age, they have a regular cycle of molting set up. At the 20th instar, which is the stage between molts, the males become fully sexually mature and are ready to engage the female in their mating ritual.
As with many tratits and characteristics with this breed of spider, the female and male Mexican Red Knee Tarantulas mature at different ages. The females, on average, mature about 2 to 3 years after the males. By this time, the female tarantulas are around 6 or 7 years old.
When both genders reach their full maturation age, they are ready to engage in their mating ritual. In this mating ritual, the male uses his front legs to lock the jaws of the female open. He positions himself behind her and bends her backwards. He deposits the sperm into an opening on the female’s abdomen and quickly flees. The males take their leave quickly to avoid the aggression that the females typically have after mating.
When the male is gone, the female carries the eggs in her abdomen until the spring. When spring comes, the female weaves a silk mat, deposits the eggs on it, and covers them in a sticky liquid that contains the male’s sperm.
After the eggs are fertilized, they hatch in about one to three months, giving birth to new spiderlings. The spiderlings stay in the egg sac that the female carries for another three weeks after hatching.
How Long Does It Take for a Mexican Red Knee to Molt?
When a Mexican Red Knee Tarantula is first born, it molts every two weeks. This frequency lasts for about the first four months of its life. After that, the frequency of molting decreases.
Once male Mexican Red Knees reach sexual maturity at age four or five, their molting ceases altogether. Females, on the other hand, continue to molt past their sexual maturation age, around age six or seven.
The purpose of molting for Mexican Red Knee Tarantulas is mainly healthcare. Molting sheds their old layer of skin which removes any dangerous, external parasites and fungus. This molting process also provides the Mexican Red Knee with a new, fresh set of undamaged sensory and protective hairs.
How Long Can a Mexican Red Knee Tarantula Go Without Food?
Mexican Red Knee Tarantulas don’t need to eat all that frequently. Usually, a Mexican Red Knee will eat once every week. In the wild, this number may vary to be more or less depending how much foo they can find.
For your pet, though, you should be feeding your Mexican Red Knee at least once a week up to three times a week if need be.
How to Handle a Mexican Red Knee Tarantula
Mexican Red Knee Tarantulas are slow moving, docile creatures, which lends them to being handled easily. Many Mexican Red Knee owners have noted that it is easy to handle these spiders often while causing no stress to the animal.
However, you must handle them with care. These spiders have a delicate exoskeleton system. If handle too roughly or dropped, even from a short height, this can result in serious injury to your Mexican Red Knee or even death.
When handling your pet, make sure you are always seated or have them low to the ground on a carpeted or soft area. Keep your hands open and let the tarantula sit or move around on your open palm. Never close your hand around your spider as this may come off to them as a threat.
If you are not comfortable handling your Mexican Red Knee Tarantula with your bare hands, you can use gloves or other instruments. Always keep in mind to be gentle. The best alternative to handling your tarantula with your hand is to use a cup or container.
Place the cup or container near the spider and let it walk into it, or gently scoop it up. Once you are done with whatever you needed the spider out of the way for, place the container back in the spider’s habitat and let it wander out on its own or gently tip it out.
There are signs you should watch out for when your spider becomes agitated so you can avoid injuries, both to you and to your pet. If your Mexican Red Knee feels threatened, it will rear up on its hind legs and bare its fangs.
This is often a precursor to a bite attempt. It may also flick barbed hairs from its abdomen as a way to transfer its venom. If you notice these behaviors, wait a little time before trying to handle your pet again.
Care of Mexican Red Knee Tarantulas

As with any animal, the Mexican Red Knee Tarantula needs an ample space to live, move around, and play in. The ideal size for a Mexican Red Knee’s terrarium is 5 to 10 gallons and should have a locking screen top.
Since the Mexican Red Knee is a burrowing animal, it is important to put enough substrate on the bottom rather than height that could be used for climbing. Ideally, you should put about three inches of substrate on the bottom of your spider’s terrarium to give it ample space to burrow.
Food & Water (What to Eat, How Much to Feed, How Often to Feed?)
It is important to keep a dish for water always full and available for your Mexican Red Knee.
As for food, the Mexican Red Knee Tarantula typically eats insects, such as crickets and other similarly sized bugs. They have also been known to eat small lizards, reptiles, and frogs as well as other small vertebrates such as birds and baby mice.
The Mexican Red Knee Tarantula usually eats once every week, though some of them have been known to eat up to three times a week. It is important to learn your spider’s preferences and adapt your care to it.
Returning to water, if your spider seems to be less than enthusiastic about drinking water from the water bowl you provided, do not worry. Mexican Red Knees can get all the hydration they need from the food they eat. However, you should maintain the habit of providing and changing the water bowl regularly so it does not grow mold and your pet always has that option if it so chooses.
Your Mexican Red Knee Tarantula’s terrarium should always be kept between 75 and 80 degrees Fahrenheit. This is the ideal temperature for your pet to live in since it best simulates the climate from its native area in Western Mexico.
This heat can be achieved and maintained by placing a heating pad under a portion or to the back wall of your pet’s terrarium.
Heating (Do Mexican Red Knee Tarantulas Need Heat?)
As long as you keep your spider’s terrarium at a constant 75 to 80 degrees Fahrenheit at all times, your pet should not need any other source of heat.
The Mexican Red Knee Tarantula does not need a high level of humidity. The humidity in its terrarium should be kept at around 65 to 75%. The humidity should never be allowed to dip below 55%, though. Keeping a water bowl in the tarantula’s terrarium will be a big help in maintaining the necessary humidity levels.
The Mexican Red Knee Tarantula does not require any lighting. However, if, instead of using a heat pad, you wish to provide your pet heat using a heat lamp, you can utilize this. However, a heat pad is more than ample to provide the heat your spider needs.
Males are typically ready for mating at ages four to five, females at ages six or seven. After the male and female mate, the eggs will hatch about one to three months later and the spiderlings will emerge from the egg sac three weeks after that.
If you would like your male Mexican Red Knee to mate with someone else’s female, it is important to keep in mind that females are usually more aggressive than the males, especially during the mating process. Females have been known to try to kill and eat the male after mating. Be cautious with your pet and try to remove it from the female’s presence soon after mating it done.
