I was once a maintenance tech for a large Garden Apartment project. It was my job every friday to spray for bugs. We were authorized to use Daizinon 4EC. A very dangerous chemical. We would give notice at 2 months, one month, two weeks, and then one week. I knocked on a door to find the whole family at home. 3 Generations. All there to watch me spray an aptartment where nothing had been removed from the cabinets. During spraying, I happened to knock the lid from a large can under the sink. Roaches poured out like hot lava from a volcano. I sprayed that can until the bugs were all out. They were crawling everywhere. I used at least a gallon of spray in their kitchen alone. To this day, the odor of curry nauseates me. But, a little protein in your coffee can't hurt.
