I was just talking to my aunt a few weeks ago about the way things were done in the good old days. And while this isn't exactally food related I thought it was interesting. She told me how when she was growing up her mama would drag out the mattresses every summer and beat them and let them lay in the sun. Then she would take a bag of sulfur and light it on fire and toss it under the house. They never had any problems with bugs of any kind, bed bugs or nothing. Now we hear so many stories about the growing problems with bed bugs.
I was relating the one and only time we had a problem was with bed bugs. My mother said came from relative who stayed with us. Which happened more than once, them staying with us, not the cooties.
Anyhow she opened the bedroom window, threw the mattresses out and burned them right there on the front lawn. I was young and don't remember to much about it. Just the burning on the lawn part.
