Nisus Tim-BOR Professional Insecticidal Dust, Water-Soluble Borate Powder, Wood Preservative and Fungicide for Termites, Carpenter Ants, Wood Decay, 1.5 lbs

Used by major termite companies to spot treat, it's easy to mix and applies with any garden sprayer. I used warm water to dissolve the powder faster in an old 1 gal jug, poured in sprayer, pumped and sprayed a bunch of my new cedar siding boards. After it dries the boards are very slightly darker, not noticeable unless compared to unsprayed board. I used SealOnce Marine sealer after the boards dried completely for further protection. For larger projects look for it in 25# buckets, way more cost effective

This is the second purchase of Timbor for me. It treats and protects as promised. Last purchase was for an outdoor table and it is still big and fungus free tears after treatment. This is going to be used on rafters and beams in a shed. Great value. Great product. Will purchase again when the need arises. Follow the directions and you cannot go wrong. Low odor and no noticable smell after applying.

Product was good

Anywhere you have direct access to damage this is the stuff.

I was worried about it being easy to use or not, the powder is quite light and fluffy and easy to spill. But it was easy to mix with water. Easy to apply and comes with instructions. I think if you seal this in an airless bag you can make it last. Better option that more toxic alternatives. Wear a mask!

Arrived on time getting ready to use

I received the white bag as on the Amazon ad. It was it its own cardboard box for shipping. Each bag is 1.5 pounds. The instructions on the back of the bag explain that one must mix one pound in one gallon of water for weaker 10% solution, or the entire 1.5 pound bag in one gallon of water for the stronger 15% solution. When you see the size of this bag, and compare it to a gallon milk jug (or yard sprayer), you'll scratch your head a bit; it'll be like someone telling you to dissolve four heaping scoops of chocolate drink mix in a single glass of milk. Indeed, many reviews state how hard it is to dissolve this amount of product in such a relatively small amount of water. Package also states to use immediately, which makes sense as the powder will settle out in about ten minutes or less otherwise. You'll have to keep shaking the bottle as you use it, if you're brushing it on then use an open container and keep the stirrer inside the bucket with your brush. While it may be good for spot treatment, such as termites around a couple of shed posts, it's not adequate for larger areas, such as the perimeter of a wooded house. You'll have to imagine a one gallon sprayer on steady stream going around the perimeter base of a wood house...I'd estimate an average homeowner will be mixing at least five bags of this product, at current price, about seventy bucks worth of product per application. The label does not specify the duration of efficacy, so it's unclear if this should be applied more than once yearly. As this is a salt-based "organic" product, I would estimate that using it more than once per year to achieve ultimate, lasting efficacy is key, particularly in areas subjected to weather.For my own comparison, the pest control guys (and I have no affiliation), when I used them, charged $75 per treatment, three treatments per year, and guaranteed no termites, carpenter ants, etc., and could provide documentation of ongoing treatment should I ever sell my house (required under state law here). Applying the Tim-bor three times a year to a house costs virtually the same. So, there's really many factors that each homeowner must assess for themselves.Does this work for termites? I don't know because I just sprayed it and time will tell. Something about it tells me that it may wash off quite quickly in rain-exposed areas, but we'll see. It is different than the chemicals used by the pest controllers, that much is true. All in all, I probably would not...taking the cost, lack of necessary treatment documentation, effort of mixing gallon after gallon, gummy sprayer nozzle, etc....use this in a consistent basis. I might use it if, like some reviewers, I had a single termited bench, fence post, small tool shed base, etc. Yoir mileage may vary. On products such as this, there are loads of opinions based in science, anecdote, and mythology, often mired in unnecessary discourse about the harm to health of chemicals used by pest controllers, and such; if you have input, write a review, it'll get many more "eyeballs" than commenting here. Thanks. For those that this helped, keep fighting the good fight. Cheers, fellow Earth-dwellers.
