i have some questions about menthol application..... i am following george imirie's recommendations...

i placed menthol in the hive today. on top of the brood frames.

i know that the menthol is supposed to vaporize, but is it normal for the bees to appear over come? about 300 bees outside the entrance the afternoon in a loose cluster, some disoriented and others just sitting there...

i know that it is important to leave the menthol treatment in the hive for the alloted time, but AM I KILLING MY BEES?

also, if i have really warm weather and this first packet vaporizes in 3-4 days, do i put another packet in there to finish out the total time period? or is it amount based?, not time period based?
