OK, What are they!

My camp has been invaded by insects that I can't identify. They are black, about the size of a small house fly and hundreds of them are crawling over everything. When disturbed they do fly but seems to be very short flights, they mostly crawl around. They don't seem to bite.

What is it?

Hmmmm, may be a sewer fly.

Make sure all your traps have water in them.

Also, make sure your [sink-drain] traps don't have holes in them! :eek2:

That's exactly what I think too.

Also known as drain fly - more wing than body. Do you have any floor drains that my have had the water in the trap evaporate this spring?

We had them at our place too, not positve but i think it is a species of the stone fly.

That looks like it.

Not sewer fly. Also none in the house just outside
