Finding a scorpion in the bathroom at midnight is a Chattanooga rite of passage — but finding them regularly means your home has entry points and a food supply. Here's why striped bark scorpions come inside, and the strategy that actually keeps them out.
The most common scorpion in the Chattanooga area is the striped bark scorpion: two to three inches, tan with dark stripes down the back, and a climber — this species scales walls, rides curtains, and drops from ceilings. Its sting is painful but rarely dangerous to healthy adults; small children and allergic individuals are the exception.
Two behaviors explain most indoor encounters: they hunt at night, and they flatten. A bark scorpion slips under a door sweep, through a weep hole, or around a window frame with room to spare. If it can slide a credit card through, it can get in.
Scorpions go where the food is, and the food is other bugs. Crickets swarming your porch light in August are a dinner bell — scorpions follow them right to the door. A home with a cricket or roach problem is a home with scorpion pressure.
Outside, they harbor in anything that holds shade and moisture: stacked firewood, landscape timbers, rock borders, stored lumber, and dense ground cover against the foundation. Every one of those against your house is a staging area.
Layer one is exclusion: door sweeps that actually touch the threshold, sealed weep-hole covers that keep ventilation but stop entry, caulked window frames, and screened vents. Scorpion-proofing is detailed work, but it's permanent — a sealed gap works every night of the year.
Layer two is pressure reduction: treat the prey insects and you remove the reason to come in. Perimeter treatment plus reducing harborage — moving the firewood, thinning the ground cover, fixing the porch light situation — collapses scorpion activity around the structure within weeks.
Wash the site, apply a cold pack, and expect several hours of pain and possible tingling — miserable but self-limiting for most adults. Watch children closely and seek medical care for any severe reaction: difficulty breathing, widespread swelling, or symptoms beyond local pain.
Then treat the sting as the data point it is: a scorpion inside means the barrier has a hole. The inspection finds it.
