After getting bit 3 times by those nasty bees I finally saw the softball size nest which was built near beams on the pen side of my coop. I'm worried if I spray the nest the hens will eat the sprayed bees. I thought of putting a tarp on the ground prior to spraying but am now afraid to go in there after seeing the nest to even lay the tarp down. Those bee bites hurt like heck! Suggestions?
