I have a few carpenter bee holes in my siding. Most of these are holes
that were treated last year and sealed up but are now open. I have an
extermination company doing work for me. They are not the ones who sealed the
holes though, and they tell me that they do not do that to the holes. They
just spray a powder into the hole. I have had my house sprayed with and
insecticide, although I don't know the name of it. I now have two different
approaches to the problem and I don't know who to trust. What is the best way
to treat for carpenter bees and to prevent them from coming back to my house
again?
Either way is acceptable. Insecticide Sprays such as Cyzmic CS do a better job of preventing bees from boring new holes.
The dusts do just fine to kill bees in existing holes. Don't seal holes until the fall.
Eggs in the tunnels will hatch and bore out in the late summer. Only then should you seal the holes.
