How can I find salamanders?

I always find red backs, slimy salamanders, and other plethodons in the spring or fall under rotting wood and flat rocks, they prefer rotting wood that you could rip apart with your hands. I don’t know where they go during the summer and the only ones I see during that time are two lined salamanders in small creeks or streams. I haven’t seen any ambystoma yet so I can’t tell you anything about them
