We used this in conjunction with Q8 Log Oil on our log home and it definitely works. It doesn't contain toxic chemicals or insecticides but uses natural ingredients to discourage carpenter bees and ants from wanting to drill. My wife and I like the citrus-herbal smell. It doesn't affect the color or effectiveness of the Q8 Log Oil. It's awesome stuff and I haven't seen anything else that works as good as this does.

NBS30 - Absolute Must

 May 2013  J&B Perlis
We enjoyed using the Q8 Log Oil. It was easy to apply and the barn grey looked great. After two years of salt spray from the gulf, high winds with blowing sand, and Florida heat, the typical color change of our cypress wood has been leveled out so it has weathered in matching fashion instead of the dark uneven blotches.The biggest surprise was the NBS 30 additive. Over the two years I have actually watched the Carpenter Bees fly toward our cypress wood, hover, and fly away. I don't have the first bee hole. We also have no wasp nest or spider webs. It's time to apply the 2nd application of Log Oil as recommended after two years and I"ll add NBS 30 again.

Outlast Q8 Log Oil is an excellent product. The protection it provides to our log homes
has no match, along with an incredibly easy application. We at Authentic Log Homes of Vermont recommend this product to all our customers. Thank you CTA for making an exceptional product.

 1/18/12  Your product, NBS30, is far too valuable not to be marketed to the wildlife removal industry as a key tool in that process. I have used it for years to evict and exclude all species of wildlife from wood peckers, raccoons and squirrels to skunks and rodents. The clients love the smell and it is safe in homes with pets and children. It is a real boon to our peoples work and in the fight to create a larger no kill service side to the industry.Those I have turned onto your product rave about it. I have had a zero fail rate using this properly.
Caution: Do NOT get the product on the young as parent may not take them then.

January 21, 2010.  I am a no-kill nuisance wildlife control operator, as well as a wildlife rehabber, specializing in critical care/triage work with all species of native wildlife.  I have been using your NBS 30 product as a mammal repellent to humanely remove animals from locations where they aren't wanted instead of the old ammonia standby, as it is far too lethal to babies and can blind both young and adults.  NBS-30 is a WONDERFUL AND AMAZING product!!.. (It) works well to repel raccoons, squirrels, woodpeckers, woodchucks, moles, mice, rats, skunks per my experience.  Thanks!  Jennifer

 I am pleased to endorse your product.  As an Entomologist, I had tried many methods of ridding my log home of carpenter bees and carpenter ants.  Every year I sprayed a variety of insecticides which usually controlled the ants, but not the bees since they were in overwhelming numbers and favored the 20+ feet heights of the house where they were difficult to spray.

April 18, 2016    My home. wrapped in cypress, was "carpenter bee central” when we bought it 5 years ago. Some of the facia boards looked like Swiss cheese. I found this wonderful NBS 30 and it has been a God-send. It was supposed to keep the bees away for three years and it actually lasted four. We are sealing again right now and you can bet your sweet behind I’ve added NBS 30 to every ounce of the sealer. I highly recommend this product to anyone with a carpenter bee infestation.



June 11, 2018  Jim, I am writing to thank you and CTA Products Group 1 LLC for your outstanding service and products. From obtaining product samples and valuable application information to speaking with CTA R&D scientists, you and your company have exceeded every expectation my wife and I have for a wood stain provider.

 We have been in our East Tennessee log home for 3 years, and are extremely happy with the Q8 Log Oil used on the home’s yellow pine exterior. The first coat of Q8 soaked into the logs and decks so completely, that the medium reddish brown color was difficult to see. Following CTA instructions, we restained after two years and are enjoying complement after complement on the color and transparency of the stain. Wood grain and knots are enhanced by the application of Q8 Log Oil. While our painting subcontractor initially recommended use of a competitive product, he mentioned his use of Q8 on other homes in our area.

We would also like to thank you for introducing us to NBS 30 Insect Repellent. We incorporated this stain additive into both stain applications and have enjoyed significant benefit. While several of our neighbors have complained of carpenter bees "riddling” their log homes, we can count the number of holes bored into our wood on one hand!

CTA provided an expectation of the second coat of stain protecting our wood from 4-8 years. One side of the home is in full sun, so we’ll let you know how the stain holds up in that demanding condition, relative to the more shaded sides.
