re: Anyone having much higher number of aggressive deer flies this year?

All flies in my are (north La) are terrible this year. My pest control company sprayed something out of a can inside the house and that really seems to kill a good bit of them (there were several dead on the floor) when I got home. I texted him to ask what the product was, and got no response. Does anyone know?

I can tell you the Zevo flying insect trap sold at HD and other stores, does not have a single fly or other bug on it. So, that was worthless attempt to control them.
