Are Tarantulas Bad Pets?

Arachnophobia is among the most common specific phobias, so it is not surprising that when you tell someone that you keep tarantulas as pets, they raise an eyebrow. People imagine danger and eight legs that are plotting your demise, hidden in the corner of your room. The reality is far calmer. Tarantulas are low maintenance, quiet, and surprisingly captivating animals that make excellent pets for the right kind of keeper.

Why Tarantulas Are Actually Great Pets

One of the biggest advantages is how little effort they require. A tarantula does not need daily attention, elaborate heating setups, or expensive equipment. Once the enclosure is correctly built, maintenance becomes simple. Sure, if you buy a baby spider (spiderling, in short sling), you will have to re-house it into an adequately-sized enclosure as it grows. But there are plenty of resources out there (e.g. Tom Moran on Youtube), that show you how it’s done. Keep the water dish full, remove leftovers, feed occasionally, and that is it. Many species eat just once per week, and some fast for months during pre-molt without any impact on their health.

This minimal care also means you can go on vacation or a work trip without stress. Leaving a dog, a cat or most reptiles for a week requires planning. Leaving a tarantula for a week is normal. As long as the enclosure is safe and the water dish is filled, the spider remains perfectly fine. They probably won’t even notice that you’re gone (sorry).

The tarantula hobby also plays a small role in conservation. Captive breeding has reduced pressure on wild populations and created stable lines of many popular species. By supporting captive bred animals, keepers indirectly contribute to reducing illegal collection. Breeding projects also help preserve rare species and maintain healthy genetic diversity within the hobby. For instance, many of the Poecilotheria sp. tarantulas are listed in the ICUN red list under critically endagered (ICUN, accessed 2025-12-09). So while the diversity in the wild is threatened, we in the hobby can do our part to help with the preservation of those beautiful animals.

One part of the appeal is pure fascination. Tarantulas look and behave like something from another world. Their movements, colors, webs, and behaviors are almost alien. Watching a tarantula engineer its burrow or slowly expand its webbing can be surprisingly calming. They offer a window into a very different form of life, one that rewards observation rather than interaction. Also: being able to regenerate lost limbs? If that’s not alien, I don’t know what is.
