No reported deaths ever from a Tarantula bite, that globally includes children and infants.
A tarantulas venom is made to arrest the functions of an invertabrate. Really it has little effect on humans as far as damage goes, but introducing a venom of any kind into your body will have an effect. Bees are more deadly by anaphylactic shock cases of allergic individuals. The machanical stab wound of a tarantula would probly hurt a little bit, but , it would be a quick strike not a lingering fang sink. I tarantula has to regurgitate its digestive juices from it's second stomach, and then slurps up the cricket goo. So if you get bit, stop the bleeding and disinfect the area.
Now a Blackwidow or Brown recluse has digestive enzimes (Tissue Narcrosis) and other nuerological blocking substances (muscle constrictors) in their bites.
But even with that, 90% of brown recluse or black widow bites are misdiagnosed.
Spiders are our 8 legged allies, and should be respected and revered. (NOT SQUASHED !!!)
