Not big at all. Seen some MONSTERS in FL. When relatives would come to visit or we'd go visit them, their monster roaches would hitch a ride back and we'd have to bomb 'em to keep them from getting a foothold at home in GA. No, the relatives didn't have an infestation... Pest control kept them in check indoors but they would thrive in the outdoor sun rooms, cars, etc. From there they would come hitch a ride home where we had no effective pest control and would have to bomb them ourselves every time we'd visit. Most people in GA have the smaller brown ones but the big flying "water bug" roaches are extremely common in FL and I know for a fact that they can thrive in GA too. It's like having a bird flapping around in your face when they take flight and breeze past you.
Edit: You bagged it. LAWL 😀
