"Yes Duet is used to spray. They spray every Monday morning around 5AM starting around the first of July. There has been cases of equine encephalitis in our county. We have a large mosquito population on our campground so in the past years we have welcomed the spraying for the comfort of our clients." if they are spraying this at 5 am and every monday morning, (so weekly) might be concerned myself, rather than at night. i would be inclined to lock them in until any residue dissipates, kills skeeters? an insect. i am with jen on this,
"where bees forage there will be chemical residue on the pollen and nectar. Just cause the beekeeper didn't notice any visual damage to the bees doesn't mean it's not there hidden within the hive". when i read a label that says TOXIC TO HONEY BEES, and the toxicity to aquatic organisms, i start to pay attention, and i don't want this brought back to my hives and stored in the combs, and i live in farm country and on a river, so lots to deal with coming back to the hive, including my neighbors that use all sorts of pesticides. bees get water from where?
also, some of our gardens, perennials and vegetables are less than 100 ft from my hives, the bees seem to find them just fine and always have.
sorry to put a kink in here, but i disagree about this chemical not affecting our bees sprayed at this time of day and bees not visiting a garden within 100 feet of a hive.....
just my HO and two cents.....
