I had painters here about 6 weeks ago. After closing all windows, etc. I had to kill numerous flies - 50?
I am still seeing flies, though not nearly as many in my house. I don't know how they are coming in. I asked the painter to come back and he cannot find that they left an opening in the wood they replaced on the house.
Any ideas?
unless of course they used bright yellow paint, which attracts flies...
