Its getting into the summertime here in Florida, and probably the rest of the South. Unlike the North we have very warm weather this time of year, and the critters are starting to stir. Every night I hear the frogs starting their chatter. Cuban Tree Frogs are bouncing around, in fact here is a picture of one I took the other night. These things stick to just about everything with those boney little fingers, including your toilet sides. They come in through the plumbing vents. Best protect them with Critter Quitters, not only keeps the beasties out but protects the vents from being chewed up. Amazon and Homedepot.com
