Hi – appreciate your web site. It has given me some good ideas.
Is it feasible for me to treat the Redwood shakes on my home for powder post beatles or will I need to contact a professional Pest control company? I live in a very rural area near Eureka Calif. We have 5 acres so no nearby neighbors.
All the Redwood shakes are untreated (no stain or sealer). Most of the beatle holes are located in the bottom rows of shakes and have not yet visibly spread to all areas. They seem to be focused on the north sides of our house. If I can do the work what would you recommend for the active spray and what equipment would I need to complete the job? I’m guessing 1000 sq. ft. The house is about 1400 sq ft and walls are 8 ft. high. All Redwood shakes except doors and windows. Any assistance you can provide will be appreciated. Thank You! Jerry
If you read our article, you’ll learn the holes you see are actually exit holes and will only be seen after the larvae have fed, pupated and left. This means where you see the exit no doubt has activity but it also means the rest of the shakes could very well have them feeding larvae too and that they simply haven’t fully developed yet. That means the larvae could very well be in those shakes munching away as we correspond.
So with this being said, you should treat every shake. And based on the number of square feet you state is present, I would say 2 gallons of Boracare would do the job. It could be sprayed on using a regular pump sprayer and would no doubt be a lot less costly compared to hiring a professional. Additionally, it’s pretty easy to do.
