Just pointing out that safety and effectiveness can be supported with scientific data, and are not necessarily correlated with "natural" or "organic". We use high-intensity farming techniques on our farm which has allowed us to devote 95% of our land to wildlife habitat. Organic production takes way more land due to lower production which eats up more land. I also think use of manure on food crops is an unacceptable risk. OK - I'll hop off the soap box now.
I hear ya on that one -- I'm only speaking for my little 1/2 acre yard. I've also learned it's important to read the definition of organic as it applies in the specific case in which you read it -- there're some wildly varying definitions of organic out there, too. My family on my mom's side are rice farmers, raised hogs & had a garden & chickens for family use -- and to sell eggs locally if the chickens were layin' good.
Personally, I love nothing better than spraying red wasps, yellow jackets & hornets with whatever foamy stuff that shoots really far they sell at HD, Lowe's or anywhere else that sells it. I'm sure it's not necessarily safe, or environmentally friendly, but it's definitely effective & I like being able to stay far away from the stingin' things!
I battle fire ants every year, too. They don't care what I use because apparently they like my yard, especially the flower beds -- the dang things mound up right at the edge of the gravel bed I've got surrounding our a/c unit -- nasty ants.
