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

Hands down amazing product you wont regret it .

I had some windows replaced so wood was exposed so that I could apply this product. My Bug company recommended this. I mixed it in a container and put it on with a rag while wearing gloves. There was no smell and it absorbed quickly. It was a fair cost and a much needed product for an older home in Florida

I watched a how to video on Tim-Bor powder and mixed a 15% solution with ease. No problem mixing 1.5 pounds in a gallon of warm water with a drill and paddle bit. Absolutely no problem. I had made some deck stairs and ordered this product to spray on them. Waited for the wood to dry out for three weeks and sprayed the steps today. I got a sprayer at ACE Hardware for cheap. I wish I would have gotten a better sprayer because the how to video guy said not to apply it so thick that it drips. Well, my deck steps look like it poured rain on them after I was done. I did some of my fence to and it was easier to manage not to drip. I will see how it does. Only time will tell. I hope it doesn't matter that I put this on pressure treated wood. I realized that Nissus makes a product specifically for pressure treated. I hope I didn't waste my money.

It works very good for termites, and different insects in my attic.

Mixes well with water, especially hot water.

We were doing some termite repairs on our wood deck, and I wanted to treat the wood for termites so we wouldn't have to do it again. This is what the termite pros often use to treat the wood in your house to keep the termites away. 1 package mixes with 1 gallon of water, and you apply it with a garden sprayer. Wear a mask; you don't want to be breathing the stuff. But you'll breathe a litle easier knowing you're less likely to get termites, and you spent a tiny fraction of what the termite company would charge.

I have been using TimBor for years to protect my wooden-based investments. I recently got a new shed and treated that as well. One great tip is that instead of just mixing with water, you can mix with water and ethylene glycol (aka antifreeze) to better penetrate the wood. I just use half a gallon of undiluted antifreeze and half a gallon of water and one bag of TimBor. This essentially makes a clone of BoraCare for less than half the price. Just be sure to use it within a few days of mixing and use proper PPE. The ethylene glycol penetrates all the way through the wood carrying the borates as opposed to just water which penetrates about 1/4 inch. Ethylene glycol also acts as an insecticide and deterrent in itself since it remains in the cellulose structure of the wood. Also this does not alter the appearance of the wood as the amount of dye in the antifreeze is so tiny. TimBor is really good stuff and its easy to make it even better with this little trick.

I think the products probably OK, but it arrived with a slit like a razor cut right through the middle of the bag. I’m guessing it’s more Amazon’s fault than the vendor’s fault.
