Does Delta Dust kill carpenter bees immediately?

Does Delta Dust kill carpenter bees immediately? I drenched two of them today and they both flew off. One was boring a nest and the other was actually in a nest. I believe one actually survived and came back to its nest. Thanks.

Answer:

Delta Dust will not kill on contact.  In fact, no product will kill a bee or other insect immediately other than Wasp Freeze or a pyrethrin aerosol.  The bees that you covered with Delta Dust will die, but not until the bees ingest the dust.  When bees walk through a hole or land on a surface that you dusted, they pick up the dust on their bodies.  Later, when they groom themselves as most insects do, they will ingest the small dust particles and die soon after.  All dust products work better the less you apply.  You should only apply a very thin light dusting of the material.  Bees and other insects have thousands of microscopic hairs on their bodies and will pick up the dust quite easily.  A pile of dust in one place will look like a mountain to a small insect and they will walk around it instead of through it.
