The Pros and Cons of Keeping a Black Widow Spider as a Pet

Black widow spiders have a reputation as the deadliest spiders in North America. However, some individuals find these spiders fascinating and choose to keep them as pets. Although there are pros and cons to owning a black widow spider, it is essential to consider both before bringing one into your home.


1. Unique Pet – Black widow spiders are fascinating creatures with their characteristic red hourglass-shaped marking. Having a black widow spider as a pet can be a unique experience that can offer you and your guests some excitement.

2. Low Maintenance – Black widow spiders are low-maintenance pets. They don’t require daily feeding or attention, and they don’t need a lot of space. They only require a small, simple enclosure that mimics their natural habitat. They eat insects, which can be easily obtained from pet stores or caught outside.

3. A Learning Experience – Black widow spiders can offer you or your children an opportunity to learn more about these arachnids, their natural behavior, and the role they play in the ecosystem.


1. Dangerous to Humans – Black widow spiders are notorious for their venomous bites, which can be fatal to humans. They tend to be aggressive towards humans and can bite even when unprovoked. Children and pets are particularly vulnerable to their bites, which can cause severe pain, muscle cramps, and other complications.

2. Inhumane Treatment – Keeping a black widow spider as a pet requires the spider to be confined to an enclosure that is much smaller than its natural habitat. This confinement is inhumane and can lead to spider stress, which affects their behavior and health.

3. Legal Issues – Black widow spiders are illegal to own in several states and cities. Therefore, owning a black widow spider as a pet may result in legal issues, particularly if they are found in regions where it’s prohibited by law.

In conclusion, owning a black widow spider as a pet has both pros and cons. While they may be appealing to some individuals for their uniqueness, owning one requires very careful consideration of the risks and responsibilities of keeping a venomous creature in your home. Ultimately, it’s best to admire and appreciate these spiders in their natural habitat while leaving them alone.
