How to get rid of flies in your house
We just had this problem; out of nowhere we noticed about 20 to 30 flies in our house. We went around and zapped them all with an electronic fly swatter. That was actually fun. The next day we noticed more flies. We are still not sure where they came from. We checked all the doors and windows; they were all closed and sealed. We did not have any dirty dishes, or trash lying around. We did not notice any dead animal smells.
