You have your ways, and I have several of my own to deal with jackets. I'm no tree hugger or bunny kisser, but I do try to do what I can to avoid significant impact on the environment. I assure you, there are a LOT of things far worse in my soil already than that little teacup full of gasoline that I might use if I don't have a can of that wonderful biodegradable and pet-safe non-toxic (to humans) RAID). I prefer the RAID, because I can shoot 'em on the fly with that and get wasp nests with it I'd otherwise have to get a ladder to reach (very obvious risks doing that).
I'm pretty sure my home was built on a retired land-fill which used to be an open pit strip mine dating back before the Civil War, though the house was just built in 1975. There are a lot of things are buried here, and they wash to the surface after every rain. We've probably picked up at least a ton of glass shards since 2004. I've found old oil cans, boot heels, bicycle pedals, BB guns, toy cars, plastic limbs of dolls, etc, etc. I wouldn't be a bit surprised if I found a piece of the medieval treasure from Oak Island. I'd certainly let Rick and Marty know if I did. I'm relatively certain the Knights Templar used my yard for a dumping ground, albeit I've yet to find anything of value. My yard is like a box of chocolates. You never know what you'll find. On top of all that, it's also at the lowest elevation of about 30 acres (fortunately hilly) meaning all the run-off from 3 streets (oil/fuel leakage from cars) and approximately 20 houses on that 30 acres (fertilizer, insecticides, etc, etc) come across my yard. When the ditches slow to a trickle, there is ALWAYS an oil slick on the water standing in them, some of which will be leaching from the layer of coal that isn't very deep here. In those same ditches, there are crayfish the size of small lobsters while it's still wet, night crawler earthworms that look like small snakes when it sort of dries out, and cicadas the size of footballs. Moving out from those ditches, I have huckleberry bushes nearly 30 feet tall, dogwoods about the same, pines that are nearly 3 feet in diameter as well as a few oaks that big, poison ivy vines that are 6 inches in diameter, rattle snakes, foxes, chipmunks, squirrels, red-tail and broad-tail hawks, you name it. Even deer walking through my little suburban lot, and I caught and relocated a racoon from my back deck . Somehow, I don't think I've hurt the environment very much at all.
