In a recent column I discussed controlling pesky wasps. I received the following e-mail from reader Pat Pope who said: "In response to the wasp situation, I found a neat little trick that I'll share with everyone. On my front porch the wasps were buzzing around too much for me so I put clear ammonia inside small candle holders and placed them around the porch, out of sight of children and pets. The wasps have taken the hint and aren't bothering me anymore." Thanks Pat!
