Idk if you can make spiders stay where you put them, and I have never seen spider shops in my life, however:
in my country we have "Chilean recluse spider" which has a really lethal poison, but fortunately we also have the "tiger spider" (idk if that how its called in other parts of the world), this Tiger spider the recluse spider predator, it's not very poisonous and avoids biting humans, therefore:
when I want more tiger spiders near my house or in my house I just grab ants (they invade my kitchen every day and night) and throw them to the tiger spider web, this way it can just stay alive, put eggs and more tiger spiders (for some reason they disappear after sometime :( ) and with this I have to worry less about recluse spiders.
