Houseflies now populate our house. I am not prepared to make concessions on their attempt to squat in my house. Therefore, we have turned to the power of the Fliegenfänger.
Frogs (or perhaps they are toads - I never audited speciation or zoology in Univ.) now populate our yard. I kind of like them. They are quite dextrous (unless a car drives over them) and I have to watch my step if I get in later in the evening.
