We have a honey bee hive in shingles and roof edge. We sprayed delta dust all over. How long does it take for them to die or leave.
If you are referring to the whole nest being dusted with Delta Dust, and the hive to die off, it can take days. The bees need to ingest the dust and also carry the dust into the larvae to eradicate the hive. You will also want to be sure that any honeycomb or honey that may be left behind is eliminated. If this sanitation is not done, then more bees may return to the same area, or you could attract a secondary infestation such as hive beetles.
