... other than perhaps a dragonfly, (which doesn't really count as a creepy-crawlie, IMO) has got to be the palmetto bug. There should not be too many of them in evidence that late in the year, but if the weather stays warm and wet, you could see stragglers on the ground at night near the bushes.
A palmetto bug is a tree roach. They don't bite, but they will fly if startled into it. This variety of roach is an outdoor bug, and is not normally found indoors. They live among the roots of large trees like live oaks, and come out to forage at night. They also tend to live in swampy palmetto stands, hence the name. My cat used to like to catch them and present them to me as a gift, which was pretty nasty. Adult palmetto bugs are about 2 inches long.
