    Does anybody know of a source for copper naphthenate that doesn't stink for months? I'm finishing the interior of my workshop, it's a wood frame with plywood siding built on a concrete slab, and before I cover the inside walls, I want to spray copper naphthenate all over the bottom plate and the lower part of the plywood siding. I guess the usual base of CN is #2 fuel oil and that stink stays around for a long time. Can a person buy powder and mix it with mineral oil or water or something?

    Gee...Copper Naphthenate is nasty stuff and will make you flap around like a fish on the dock. Normally you only use it on fence posts and boat dock timbers.

    You can purchase it premixed ready to paint at many hardware stores. Ive seen the ....Black Flag TERMIN 8 Brand ....on shelves.

    Yes, paint it on - don't spray and atomise the stuff all over. The pre-mix doesn't stink, either that or it screws with memory..... I cant recall !

    It is illegal to use it in living spaces because of its toxicity. You may end up with a house that will be impossible to sell too.

    Copper naphthenate is relatively safe and effective, that is why it is still sold to the general public.

    I'm not concerned with it's nastissity. Dealing with post borer beetles, termites, cockroaches, spiders, snakes, mildew, fungus and centipedes, 100% DDT dissolved in a liquid nuclear waste by product would be fine with me. Alas and alack, I cannot find any. That is why I'm asking if copper naphthenate can be procured in a non-reeking formula.

    I usually put it on with a garden sprayer under low pressure so it is a coarse spray that doesn't atomise or mist up.

    I think the Termin-8 might be mineral oil or even water based, with no stink or not so much, so I think I will try that. I think the fuel oil base has more staying power when used in the ground for fence posts, etc.

    I was the groundskeeper for all the sports fields in the county for a few years. There is an incredible amount of chemicals spread around the worlds sports fields, golf courses, private lawns, etc. to fertilize, herbicide and pesticide everything into respectability. Your body contains a measurable amount of Round-Up, no matter whether you want it or not. I had a grounds keeping tome that thoroughly explained the chemicals and their effects on humans. In the list of toxicity and harmfulness, gasoline was one of the most toxic and harmful.

    I'm wondering if maybe I should just squirt some gasoline all around instead of Copper naphthenate.

    I don't live in my workshop. Post borer beetles, termites, cockroaches, spiders, snakes, mildew, fungus and centipedes do, but I'm fixin to kill those *************.

    Copper naphthenate is not available as a single organic copper salt, only as a mixture of many similar crude oil fractions. Because all of these share the same properties as wood preservants and have a strong odor, the industry does not separate them.

    I sprayed the beams of my roof with such a product; the smell is unbearable for a couple of weeks, nasty for a couple of months. That was approx 10 years ago, the smell has long gone, but I also find some wood dust under the beams, so I guess the borer beetles are back.

    I'm not sure about creosote. It's nasty and I've seen plenty of creosote soaked railroad ties just disintegrated from something, bugs or fungas.

    A guy was telling me they built a house and didn't have any like Thompson's Water Seal floor sealer to protect the subfloor while it was exposed to the weather so they used fuel oil. The subsequent owner was perplexed for the rest of his life wondering why he couldn't find where the leak in his fuel oil system was. Ah well, what fun is life without mysteries?

    I have been using Timbor, which is dirt cheap powder you mix with water. Bora-Care is the same, but comes pre-mixed with an ethylene glycol (anti freeze) base which is also a surfactant and 'makes water wetter' so it soaks in more and isn't leached out so easily. It is also a lot more expensive. So I'm thinking of visiting some quick oil change places and getting a bunch of free used antifreeze and mixing my cheap Timbor into that.

    My workshop is on a slab, but my house is on block piers with about an 18" crawlspace. It's creepy under there. One time a small spider fell in my ear (I didn't know it) and for a week, laying in bed at night I could hear it rummaging around on my eardrum. I'm wondering what is that? and squirting hot water in there to wash out whatever was making my ear hurt. Finally I tilted my head and put some hydrogen peroxide in there and the little fart came running out of my ear and down my cheek. That was a surprise.

    So a few months ago I find a baby copperhead snake in my carport. I do not want to go under my house any more, but there's bugs so somethings got to be done.

    My plan is to get about 16' of plastic pipe with a 1' tee on the end, put a few sprayer nozzles on the tee along with some wheels and pump my Timbor/antifreeze mixture through that while wheeling it around from outside the house. Hopefully it will stop my neighbors cat from shitting under my house too.

    To banish pests I use noise. Fit small stereo speakers under the structure then play a continuous track of THE BEE GEES ... staying alive. Nothing can withstand this...nothing

    Sam be careful with the anti freeze if there are animals around. It is deadly poison to dogs. The stuff is sweet tasting and dogs seem to like it so it is doggy suicide. It might be bad news for cats too.

    I guess our dog would do that, its got a thing about licking the furniture and stuff, plus, if you take the dogs word for it, we starve the thing. It will eat anything.

    I wonder how long it would be a hazard...forever? Or does it lose it's appeal eventually?
