I have carpenter bees excavating a nest on top of a large stump in my property, right by the deck. I want a non-toxic repellent for this, but don’t really want to harm the bees or my dog. Do I purchase liquid NBS and pour it down the hole?
If you read the write up on the NBS INSECT REPELLENT, you’ll learn it won’t kill anything so it’s a good option for deterring this unwanted behavior. However, if the bees have already begun laying eggs, they might be reluctant to move away. Think of it this way.
If you were raising some kids and living in a home which was quite comfortable for you and your family, you wouldn’t simply move away if you came home one day and noticed something foul smelling on the siding of the house. And if your kids were inside the home, you’d no doubt make sure they were safe and do whatever you could to make the smell go away so you could continue living there. But you wouldn’t readily pick up and leave without trying to make it work first.
The same is true for any bees with an established nest. If you were to spray or pour the NBS down and on the wood where the drilling is happening, no doubt the bees will smell it. But if she’s got young or eggs inside the nest, she probably won’t just pack up and move. In fact she’ll most likely try to wait it out hoping the smell will wane enough to be tolerable. Now there is a chance she will give up easily if the nest is new and not important but it’s a 50-50 chance. NBS was really invented to stop new bee activity and not to drive away bees which were already established and nesting with young and it’s important to understand this trait of the product.
In summary, there is a good chance the treatment will chase away the bees doing the damage. But if the nest is established with young or eggs, you’ll have to treat it with the DRIONE DUST as explained in our CARPENTER BEE CONTROL ARTICLE to get rid of them once and for all.
