Just wondered if there was a sprayable liquid that could be put through a 2-3 gallon sprayer??? Our campgrounds in northern Ohio has them boring into our picnic tables. tks
As explained in our CARPENTER BEE CONTROL ARTICLE, these bees don’t really discriminate when it comes to wood. Picnic tables are commonly made from pine, redwood and cedar and all three will be drilled out and bored into for nesting if left untreated. Fortunately there are some sprays available to stop the damage and nests from forming.
If you intend on painting or staining these tables anytime soon, be sure to add some of the NBS INSECT REPELLENT to your choice of finish. This treatment will last 1-2 years and will stop wood destroying pests from trying to use your tables for nests. NBS isn’t a pesticide so it won’t kill anything. It only works as a repellent. Another product you can spray is the CYPERMETHRIN. This product is a pesticide and as such will last at least a month and it will effectively repel and kill any insects coming in contact with treated surfaces. So these are the two options we suggest both of which can help keep boring bees away.
However, as explained in our article, you’ll first need to dust active nests with DRIONE before spraying. This is critical as the spray alone will not take care of the problem; it’s really only used to repel the bees and stop new nests.
