Me neither. I have never quarantined any T or even trapdoors that I catch in my backyard.I don't .
Or if you happen to buy a WC spider infected with Nematodes that ends up spreading thru your collection and killing them all offQuarantining tarantulas would really only be worthwhile if you had a communal tarantula going in with other communal tarantulas....
The chance of nematodes spreading from one WC tarantula to other tarantulas seems unlikely. The more likely occurrence would be nematodes in substrate you used in multiple enclosures or in your feeders.Or if you happen to buy a WC spider infected with Nematodes that ends up spreading thru your collection and killing them all off
