And I hived them around 7:30 pm (as soon as I could.) I hope they do fine through the night. I am in Corvallis Oregon and the weather has been in the low 50's and tonight is supposed to get to 32 *F. They were very fresh packages as there were only about 100-150 dead bees in the package all together, including the ones I may have killed. I only got stung once and that was while attempting to pick up the small clusters of bees that fell to the ground as I was tapping the packages to get out the bees. Its funny how unprepared you feel when you instal for the first time even after you have read and re-read several books. Wish me luck!
