Answer: If your compost is heating up properly, it will repel rather than invite insects. For a really hot compost pile, turning is essential and providing a good balance of green and brown material is necessary. When you turn, move the material in the center (the hottest part) to the edges and the cooler edge material to the center where it will heat up quickly. This will help it cook at high enough temperatures to deter cockroaches. To further heat the pile, throw a few shovelfuls of soil on top, or sprinkle the top with a granular high nitrogen feritilizer.
Best wishes with your compost pile!
