Can Tarantulas Kill You?


Tarantulas are one of the most favorite spider pets. You will have a long-term relationship with your eight-legged spider, so before you are going to make this commitment, it is imperative for you and your pet to also understand every detail about them before you bring them home.

Being famous for their long lifespan, tarantulas can live up to 20 years of their lives in captivity. They take very little space and are fairly easy to maintain, making tarantulas a fascinating pet to have at your home.

As tarantulas are docile, it is not the best choice for the owners who want to have hugs and cuddles with their pets. Tarantulas love to be left alone rather than being cuddled and pampered by their owners. Also, tarantulas lack emotions, making them different from other pets like cats or dogs who get attached to their owners.

Well, this question is the most asked by the people who are curious about spider pets. But when we talk about tarantulas, they do not usually bite humans until and unless someone provokes them. They usually do not want to use their venom onto the things they cannot eat, and as humans are big enough for them, they usually do not bite humans.

Tarantulas are shy, so they prefer to run away when they feel threatened. They also have another defense in which they use their urticating hairs present on their abdomen. Whatever is pursuing to threaten them, tarantulas pull out these hairs and fling them back.

They are very good at aiming, and these hairs can be very irritating. These hairs are stuck in the eyes, noses, and mucous membrane that causes excellent irritation.

When tarantulas feel threatened, and in distress, they will stretch their bodies to look greater and do whatever they can to get the threat away. Tarantulas also make hissing sounds to indicate that they are threatened by rubbing the hair on their abdomen onto the floor.
