Funny that you should mention it, although I know nothing about frogs or toads, we have been seeing the same thing this year, we used to get a couple frogs during the summer in our yard, this year we have about a dozen that cling to the window wells and to the corners of the underside of our entry about 10ft up. We have also had an invasion of lizards, at least five fold of what we would normally see.
Invasion maybe
