Narrative:

It is becoming all-too-common to see the ground crew member fail to follow safety protocols. Today was the latest occurrence. The sprayer neglected to tell us he was starting his process even though we were both in the cockpit with the door open. This is the second time in two weeks I've seen this. I've only been in the area two other times when spraying was underway recently.another issue with today's event was how the spraying was done. I haven't been trained on it; so there may have been nothing wrong; but the sprayer did little more than march rapidly down the aisle waving the spray machine back and forth like he was swatting at flies. He did not pause to spray into a single row or overhead bin.I would like to think this is something that could be better trained on several levels.
