Was just worried because shes never been effected before and she has been doing it for nearly an hour and a half now but thankyou, will get my boyfriend to check on her when hes hokeShes probably stressed due to the vibrations from the hoover, youd be surprised how sensitive a they can be!.
I wouldn't worry too much
You might try to sing her "Hush, little baby" or another lullaby. It won´t calm the spider down, but you´ll certainly look strange and be a source for amusement to anyone else present.
There´s nothing you can do, just leave her be. The only reason for concern is if the tarantula is housed wrongly, with too much space to climb. Terrestrial tarantulas aren´t too good climbers and a fall from the walls might injure them.
