I treated my two hives in August 5 treatments, 4 days apart in mid August. Then on December 23, 2018 I treated again. I DID NOT do an alcohol wash after the treatment in August, and did not open the hives in December. I chose that day because the temperature rose to about 50 degrees. I just inspected the hives and there is still a lot of honey, several dead bees, and very few live bees, no brood. I did not do an alcohol wash thinking the OA would be effective. are there any reports of OA failure? I burned 2 grams of OA over 3 minutes and closed up the hives for 10 minutes. there was vapor coming out at the top of the hives. I thought I was good>
