Yeah, that's typically what they do sparky, now if your overflow is like mine, I think the LED's will bring them in when the male releases them at night. Or some use a fry catcher with a couple LED's on them. One company makes one for like 120 dollars. A member of my local club is raising false percs that he caught with the same method form fry in his DT. He has over 200 clowns that will be ready soon.
