I returned to the house today to find that those two houseflies I’d seen had apparently gone and multiplied, as they tend to do. So, last few hours were spent manually fighting them with a dishtowel and magazine. I took out most of them, and am going to pick up fly traps tmrw. I can’t find the source, which isn’t good, but I’m removing the trash from the kitchen in the hopes that that will deal with it.
Maybe somewhat strange, but I feel really bad that I had to deal with them the way I did 😦 wish they didn’t show up in the first place.
