Super sticky insect trap substance is about all I can tell you. I’ve caught over 25 yellow flies at the time while walking and wearing that plate.What is tanglefoot?
That area of Florida and east and west of there is the worse I've ever seen.Never heard of em until we got the place in Sopcboppy. Pulled in and they swarmed around the truck. Thought it was yellow jackets. Relieved to find out it wasn't. Pretty soon I wished it had been yellow jackets cause I could get rid of them. Yellow flies are relentless.
