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

Very easy to apply using pump garden sprayer. Covered a large area and soap and water cleanup! I am optimistic that this product is a solution to preventative termite and carpenter ant issues.

Great prod

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.

I use this one on my back deck and it’s pretty much the same as only time I’ll be able to tell how well it works. Easy to apply. Doesn’t smell bad at all.

Works very well

Easy to apply, will use again and easy to clean your tools using water. I applied it using a Chapin 20000 Garden Sprayer 1 Gallon Lawn - https://www.amazon.com/gp/product/B000E28UQU. I'm not able to verify how effective it is to prevent wood damage, but I trust it is better than not using it at all - that is for internal wood structure, or external where you don't want any discoloring of the wood. I also got Zap-A-Roach Boric Acid - https://www.amazon.com/gp/product/B00LLQ4AU8 to put between the walls, on the base studs to further prevent termites. I would consider using a stronger product for external non visible wood structure, like Copper-Green - https://www.amazon.com/Green-Products-30001-Preservative-1-Gallon/dp/B00CDWRXYY but may contractor used it for internal studs at using that product it took about 4 weeks for the product to stop smelling, so that is why I started using PenaShield instead. In the end of the day galvanized metal studs seems to be the way to go for new construction....

After an infestation of carpenter ants left major damage on my 150 year old house, I used this on areas inside soffits with bare wood to prevent a repeat performance. This and an external ant deterrent helps me sleep at night.

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.
