I didn’t believe it, but since I’ve gotten rid of my cats, I’ve had two scorpions in my house (one I saw, and one stung me). On the other hand, I also saw one earlier when I did have cats, and their presence didn’t seem to make a difference. Is it that the cats chase the scorpions? I guess if so it would depend on the temperament of the cat.
BTW, I’m in the Phoenix area and I’ve lived here for three years. It’s only in the past month that the scorpions have been showing up.
It would depend on the cat. Like with mice, some cats are absolutely terrific mousers. Others could care less about a mouse.
For everything I’ve heard about cats controlling mice and/or scorpions or other critters, you can also find cats that can’t be bothered to chase and/or kill such things
