OK, 3 weeks after my last treatment, here's a report. I took all the acro's and dipped them again within the last hour, except this time with Coral RX at 1.5X strength....... and NO AEFW at all. phew..... The Coral RX is clear, where the Bayer in the treatment is milky and although adults are large, they can get quite small - I didn't want to miss any if they were there. I scrutinized the dip bucket, and also the first rinse container. Can't tell you how relieved I am. Next week I'll mount all my acro's back in their place.
