Last night I was out playing videogames and saw something on top of our kitchen cupboards. Just enough to catch the eye.
Creepy.
My last house I was renting, I got up at night and went out into the kitchen for a glass of water. My counter was cluttered and something moved amongst the clutter, but I lost it. I got a glass and the water pitcher and set the glass down on the counter... then saw it.
A 4" bark scorpion, prowling around looking for dinner.
I had so many scorpion problems in that house... I must have killed a hundred and poisoned another several hundred.
That particular one got his tail cut off with my Buck T119 hunter's knife, then the body skewered with the blade, then taken outside and squished.
I think my dog acted mopey at that house because he was getting stung often and I didn't know about it. He was sick... not mopey.
Good luck with your vermin.
