We don't even really have flies yet as it has been cold but at night this damn f*#@in' fly keeps sitting right on my camera lens. i guess it is attracted to the infrared light. and there is no way for me to prevent it...ugh
That's a great idea. I think I have gnats occasionally land on mine, and they look like ghost insects in the infra-red lighting. I'll try the Swat idea around the lens. These are the far reaches of experience in breeding!
We have a spider web strand on the corner of the lens, which is very distracting. We got a new camera which is much more sensitive than our former one, and it picks up all the dust motes at night. It looks like the mare is standing in a blizzard.
