No. It is riddled with inaccuracies and ridiculous impossibilities.

Why would any exotics keeper be handling a widow spider? It just doesn't happen.

The article implies that he was just bitten and died....black widow bites are almost never fatal to a full-grown human, and most humans show symptoms for hours to DAYS before drying from a neurotoxin bite like a widow's.

Termites do not eat flesh.

Boa constrictors are very docile and not dangerous animals, unless they are over ten feet and unusually aggressive. Nobody would let such an animal free-roam, so there was no danger from the boid.

The types of heating elements used for invertebrates do not explode. They literally cannot. Also, most people feed their spiders CRICKETS, I've never heard of anyone feeding a spider termites.

Lizards are not in the habit of tearing flesh off of things and then leaving them around for tarantulas to pick up. Even then....tarantulas eat LIVE PREY, not chunks of dead flesh off of the floor. The only lizard mentioned was a gecko....(who knows what species) and geckos wouldn't eat mammalian flesh.

There are no bird-eating spiders besides one species of tarantula.....and the name is a misnomer, they don't eat birds!

I could keep going, but the whole thing is completely absurd and not believable in the slightest.

Edit: NYAAAAAAAH!! BLACK WIDOWS ARE VENOMOUS, NOT POISONOUS! *Explodes*
