I never had much luck with ant patterns in the spring.My best luck with ants seems to be in the summer.It takes some warm days to get them moving.The later part of summer has been the best for me.I have never tried the chernobyl ant.I prefer a small flying black ant or a small hard bodied ant.I have used a red ant pattern with a little weight tied into it with great success on summer steelhead on the lower Rogue river fishing the riffles in August.
