I run my shop out of my house here in Iowa and I had a deer come in early October that had gnats I didn't recognize on it. I just figured they'd go away. They have since thrived. I'm not sure what I'm up against? These are not your average gnats that hover over your garbage or kitchen sink. These guys dart all over and are not very smart most times can kill them easy. The scary part for four consecutive days I know I've kilt 20-30 per day. Its not like they are flying all over they are just one here one there and really add up. When a fresh deer comes in they are highly visible all a sudden, however. Trying to figure a name on my gnats/bugs so I can wipe them out! Any midwesterners relate?
