I'm a sideline/hobby guy with 50 hives in Southern Illinois.

I have a few bees on long term (all summer) pollination (fruit and veggi producer) and they are doing well.

I am scheduled to do a small pumpkin job with 10 hives starting in late July. Having read the general comments, I understand I will be looking at bees not in top form when they come back to me.

Any tips about hive placement before and after the grower sprays Sevin? Any general tips from you beeks who have learned some costly lessons that I want to avoid?
