Is this safe under a dishwasher?

Yes, as long as you don't eat off the floor under the dishwasher.

After you spread the powder, do you see the roaches die on the floor , or it take days or week.

This Boric Acid will absolutely kill All roaches, however it will happen slowly over a period of a few weeks. The roaches track it back to the hiding places and it distroys all eggs and other bugs. This is the way to finally be rid of roaches. We did it 4 years ago and have only seen 3 that maybe came in thru garage or open doors. Put it anywhere there is a hiding place, the pump is very good for under cabinets and under appliances. Cover all entrances . Do it and be rid of them! I don’t think It will hurt anything. Nothing at our place, that I know of.😎

This is a powder to spray onto hard to get area's not tablets?

Yes! It comes with a plastic accordion pump that scatters a thin cloud for you. Remember roaches lick their appendages. That small amount in ANY super narrow space will be their death.
