How the heck would a scorpion get into somebody's backyard anyway? I don't think it's possible, since it's not a common, everyday insect like an ant or a bee.
Ah, suspension of disbelief! lol
There was a thread on a website about the scorpion on Honey, I Shrunk the Kids asking about scorpions in the backward, and I made one of the answers. I can't find that thread now.
My research showed that scorpions don't only live in the desert. Different species of Scorpions live in almost every type of environment. My research for the answer also turned up the information that Scropions are found in more than half the states in the USA.
Scorpions are found on all continents except Antarctica. The diversity of scorpions is greatest in subtropical areas; it decreases towards both the poles and the equator, though scorpions are found in the tropics. Scorpions did not occur naturally in Great Britain, New Zealand and some of the islands in Oceania, but have now been accidentally introduced into these places by humans.[24] Five colonies of Euscorpius flavicaudis have established themselves since the late 19th century in Sheerness in England at 51°N,[25][26][27] while Paruroctonus boreus lives as far north as Red Deer, Alberta, at 52°N.[28] A few species are on the IUCN Red List; Lychas braueri is classed as critically endangered (2014), Isometrus deharvengi as endangered (2016) and Chiromachus ochropus as vulnerable (2014).[29][30][31]"
Scorpions are xerocoles, meaning they primarily live in deserts, but they can be found in virtually every terrestrial habitat including high-elevation mountains, caves, and intertidal zones. They are largely absent from boreal ecosystems such as the tundra, high-altitude taiga, and mountain tops.[32][6]
They are surprisingly widespread and hardier than you might think. One species of scorpion is even found in the much chillier UK, believed to have found its way there as stowaways on ships in the early 20th century.
There are scorpions in California, certainly.
