|I have a compost bin that has been frequently been visited by large water bugs &/or(cockroaches) at various times especially in the summer (to be expected). I don't like these particular type of insect pests and do a fairly good job of preventive and maintenance program for my home. I do not have a professional service to combat this! Apparently, I have not done as good a job as I need to since I still see|
|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!
