Nisus Tim-BOR Professional Insecticidal Dust, 25 lbs | Water-Soluble Borate Powder, Wood Preservative and Fungicide for Termites, Carpenter Ants, Wood Decay

I have had good results using this to avoid and to kill termite issues. Toxic as one would expect, so don't take short cuts - avoid skin contact and inhaling dust. Don't use it where your pets of kids will walk through it. In one case, I was able to drill holes into a 2x6 door jamb and mix a slurry with water which I injected with a small syringe. Problem solved with only one application.

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.

great and effective termite killer.

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.

GOOD STUFF!!!! Of course time will tell me how well it does its job, but easy to mix, dissolves well, and will spray out a garden pump sprayer. I didn't see anywhere on the Amazon site page where it said how much one bag will do until I got the product and read it does one gallon. But that was enough for what I was doing.

I bought two bags which was more than enough to cover the back of my 56’ home, bare wood siding recently installed. We boiled one gallon of water and then instantly mixed the powder in and had no issue dissolving like other reviews have stated. On the first pass, we followed instructions with 1 gallon water to one bag of powder for the 15% solution. One the second pass, we did as another poster suggested and mixed with half gallon of antifreeze, half gallon boiling water, one bag of powder. It instantly absorbed into to wood so much faster than the first coating. Ease of use and price of product is a win for me! Only time will tell how well this product works, but I’m hoping that I have as much success battling off termites as others have had!When I bought my home, it passed inspection for termites. In less than a year we started to find termite damage throughout the house. I used termidor foam in the house, taurus in trenches around the slab, and within 6 months found new termite damage in my shop out back, but none in the house or around the front of shop that was also treated. We redid the entire house and all buildings with the trenching and Taurus treatment and have seen no new termite damage since. Hurricane Harvey damaged siding to the home and I haven’t been able to repair this. We had an energy company test the home and found that there was tons of air leakage where the missing siding was. This was putting a strain on my AC and raising my utility bill to an astronomical size! I had enough Bead Plywood to use as siding but have been reluctant due to previous termite issues. This product, my research into it, and all of the positive reviews gave me hope. If I can use what I have, treat it with this stuff, and replace the siding and it work for a few years until I can have the entire home re-sides, then I’ll be through the roof with excitement! Only time will tell.

I treated the wood (unfinished poplar baseboard moulding) as directed using 15% solution in sprayer. Three days later I filled holes and primed. Seems that a few little buggers still lived. Maybe this only works on powder post beetles and not on death watch beetles? Either way I was hoping for dead beetles. Maybe the infestation was too widespread.

Great item and price, well packed. Arrived as scheduled. Haven't used it yet. Will review after three months
