So it's difficult to tell if it's been useful as it's all hidden beneath baseboard and thresholds. Maybe if I removed a piece I might find bug corpses, but I don't need to know that bad ;) . Looking back and thinking about it now, I would have been more generous with the diatomaceous earth and really loaded it up, but I only had less than a quart with me, so I sprinkled it in lightly. I am glad I did it and I will say we don't see hardly any of the crawling kinds of bugs in the house, so I imagine it's having some sort of impact.

These gaps often end up being bug highways, and I figure now's my chance to take proactive measures for indoor bug control, especially since I refuse to spray bug poisons. I used a shim to scoop DE from a mason jar and sprinkle it into the gap before the baseboard was installed.

leaching from Asphalt
The use of recycled asphalt pavement (RAP) as road base material is an increasing trend in the road construction business.
... When subjected to rain water, these heavy metals and PAHs have the ability to leach out of the road base and
infiltrate into the water table, potentially impacting the quality of drinking water.

When you say the bloke will not do what you asked, can you give more details.
