If you know you have powder post beetles and are about to stain the home and wish to treat with Bora-care, is it OK to do it in the fall? The home will be power washed and is in poor condition with the stain being quite worn (probably a 7-10 year old stain job. I have seen some articles saying as long as the stain is more than 2 years old, that the Bora-care will soak into it just fine. What are your thoughts?

Is there a certain time of year that spraying works best? We have powder post beetles in our barn beams. Is it too late for this season to spray?
If you read through our POWDERPOST BEETLE CONTROL ARTICLE, you'll learn this pest is active year round. They don't rest or go dormant. However, the treatment needs to be done when it's fairly warm out and above freezing if you plan on using BORACARE. As a general rule, you don't want the daily average temp to get below 50 degrees but it's okay if gets down to the 40's for a little while. Of course if the barn is heated this wouldn't be a problem. But if it's fairly open like most barns, the temps will vary with the local seasons. Averages in the 50-80 degree range would be ideal so maximum penetration and coverage can be obtained. But if you're up north and it's winter time, waiting till the spring or summer would be suggested.
