The woman had recently been on holiday in the Adriatic country, where scorpions made their way into her suitcase.
"They are currently in the Linz animal shelter until they make their return journey," read a Facebook post from the Austrian rescue centre, which thanked the caller for reporting her find.
As unusual as this seems, it is the third time in less than 12 months and the second time this summer someone from Upper Austria has reported finding scorpions in their house following a trip to Croatia.
Fortunately, the scorpions posed little harm to the woman.
According to the National Geographic, there are almost 2000 species of scorpion known to man. However, only about 40 are poisonous enough to kill humans.
The venom from a scorpion sting can be very dangerous and cause breathing difficulties, bleeding, redness, itching, swelling and severe pain.
Fortunately, scorpions from Croatia, and particularly along the Adriatic coast where many travellers spend their holidays, are not venomous enough to be lethal.
According to a locals, scorpions are comon in Croatia, but don't pose a serious threat.
"Scorpions are ugly but really there is no danger if you see them," said a resident from Zagreb. "Do not kill scorpions because they are a protected species in Croatia.
"Scorpions are very common on the coast and they tend to come in the houses as well," added another.
"However, they are small and basically harmless, I see them regularly when cleaning around my house in Zadar."
