First thing you do is get a spray schedule, a lot of beekeepers are getting out of orange groves. Several grove owners are spraying before ,during ,and at the end of bloom. Its getting really hard to find decent groves. A lot of these grove people would not do anything to hurt your bees, they believe what they're beinging told(it won't hurt the bees). Your problems will show up 2-3 months later.We'er done with oranges until they come up with something better. Good Luck
