Beefy, yes they're wood poles. Ga. Power wrapped them in hardware cloth to keep the woodpeckers off. They changed one or two out a couple years back and still used the pine poles. I guess mine will be switched over to concrete one of these days. Hey, I'd rather have to look at concrete than those grotesque galvanized trussworks that you see trashing up the landscape.
Gertguy, yes those fly tags work well. Don't remember the active ingredient, or the name of the tags. I used tags called python magnum for two years. I don't remember the active ingredient in them either, but was advised to change active ingredients every two years. The pythons were blue. The pythons cost less, only required one. The silver tags required two (one in each ear, shown in the pic). I used the silver ones last year and will use again this year. Then in '09 switch back to the pythons. OK, I just googled python magnnum and they use pyrethroids. So, the silver tags must use an organophosphate. I've been well satisfied with both.
