I recently discovered I have carpenter bees burrowing into my hedges and they have effectively killed several sections of hedges. How can I get rid of them?
Carpenter bees will many times target dead or live trees or shrubs for nesting. And in some cases, if there are enough nests drilled on a live tree or shrub, the impact can be significant.
To stop the nesting and save your hedges, you have two options.
The simplest and most direct approach would be to watch them around the hedges to see if you can locate their main nest entry points. In most cases, there will be 2-3 holes used for most of the activity. And if you can identify these holes, directly treating them with DRIONE DUST will provide an instant cure. Its easy to use with a HAND DUSTER and if you do the application in the evening hours around dusk, you’ll assuredly get any inside and shut down the nest immediately.
But if you’re not able to isolate their entry holes, the next best option would be to mix up some OPTIGARD FLEX in a sprayer and saturate the entire area using 2-3 gallons of mixed solution. This material is very different from traditional pesticides because it doesn’t kill insects on contact. In fact this product won’t be detected by the bees (or any insect for that matter). Basically they’ll go about their business as if nothing was even applied.
But this is very much by design. You see, Optigard will eventually “kick in” and start to kill them after 3-4 days of the treatment. But by that time it will have spread to every member of the colony so by the time the bees realize there is any danger, its too late for them to relocate and avoid the treatment. At that point they’ll all die off.
So if you’re unsure of the entry hole locations, “blanket” the area with Optigard and you’ll get the same result as treating directly with the Drione.
