The simple answer is yes if sprayed directly on them. Most pesticides will kill carpenter bees when sprayed directly on them. What you are really asking is will it make them go away - and the answer is probably not. The reason is that carpenter bees make holes in the wood in order to lay eggs. These holes need to be treated individually and sealed. Then the wood surface needs to be treated with a microencapsulated insecticide such as Onslaught Fastcap.
Here is what I recommend for carpenter bees -
1. Treat the individual holes with insecticide dust such as Tempo dust, or similar dust. Inject this dust into the holes with a puffer duster.
2. Seal the holes with a color matching wood putty.
3. Spray the entire wood surface with Onslaught Fastcap. This establishes a barrier that helps to kill carpenter bees when they land on it.
4. Repeat the entire process every few weeks until they are gone. You can try using Tempo SC if you have it, if not then I highly recommend Onslaught FC.
If the bees are swarming and won't allow you to dust and seal the holes, then spray the Onslaught Fastcap first to knock down the population.
Hope this helps.
