PenaShield Penetrating Wood Preservative, Termiticide and Fungicide, Ready-to-Use Formula for Termites, Carpenter Ants, Wood-Boring Beetles, Wood Decay Protection, 1 Gallon

I am a handyman and I typically do complete home remodels including tearing out the interior walls down to the studs on older homes, (typically homes built in 60s-70s). I have remodeled very few homes that did not have termite and/or wood ant damage in the walls. Once I tear out the walls and repair any damaged frame work, I spray this on all the frame work from top to bottom. After everything is dried, I sprinkle food grade diatomaceous earth in between the studs at the bottom plate prior to adding the insulation. One thing I have noticed is at times the termites do not eat the wood but eat the paper off of the backside of the drywall, so I spray the backside of the new drywall with this prior to installation. There is no smell with this product and it dries quickly. I find that the gallon bottle will treat about 2 normal bedrooms but I drench the framework pretty heavy and I figure the cost is worth it for lifetime protection. I use a one gallon pump sprayer to apply and I do not dilute the product. Just a fine mist does the trick. This stuff is fairly safe to use but I still wear a mask and eye protection when spraying. I feel this is a great method for the prevention of termite infestation and probably the best thing a person can do other than call a pest control specialist. I personally, treat the outside perimeter of my own home with BIOADVANCED Termite Treatment which has to be applied yearly but is easy and somewhat safe for the homeowner to do themselves and is less expensive than an exterminator. I have used several gallons of this product and it gives me security that I can pass on to my customers.

worked great

I put it on some replacement posts so I guess we'll know if a few years just how well it works.

this was recommended to me by a contractor to treat the wooden frame I was putting in the basement. It had very good absorbency, even coverage, but the smell !!! it is very strong. I had all windows open, but because it is underground basement it was hard to get out. I hope it was worth the trouble dealing with smell and it will keep our basement termite free for years to come.

Used this to save the side of an outbuilding I have and it worked! I had to rebuild part of a ground level wall but was unable to remove every single last piece of the wall. Soaked it in the Penashield and months later it has done the job and stabilized the wall. In spring I will be doing the same repair to the other side of the building and the first thing I'll do is order Penashield.

This product works very well and the quality is excellent

As a dissolved mineral salt, this liquid is low or no scent, is easy to use, leaves behind no color or oil, and the residue is generally not dangerous for mammals like you or your pets. But it does kill termites and other insects and lasts indefinitely long. The exterminator we consulted recommended the borate salt spray for home use specifically because it's safe for the homeowner to apply, and because it lasts a long time (the salts absorb into porous materials like lumber). One thing to remember is that the salt solution will darken or stain wood so use with caution on wood outdoor furniture and the like.

I have bought this product 3 times. It seems like a good product. My issue is they seem to have different manufactors making the product one in India and one here in the US. The first two times I bought the product I recieved the one that looked as pictured here, seems to be the one made in the US. The last time I bought it the product looked different and had a very strong smell to it and a yellowish color. It was applied outside and the odor remained over 24 hours after application. This did not happen with the first two times I ordered this. If it wasn't for this I would rate it 4 stars.
