Is it normal for insects to invade a composter? Is it bad for the compost? Is there something I could do about it? Thank you

There are a number of insects that normally inhabit cold-composted piles especially those that contain large amounts of wet kitchen scraps. The insects generally are no reason for concern, in fact they aid overall decomposition. Hot compost typically has less insect activity so turning the compost periodically to add oxygen will help it heat up. Just moving the warm center to the cool sides will increase the temperature, as will adding a shovelful of soil to your composter every once in a while. The soil contains microbes which will speed up the decomposition process and really heat things up. In fact, it will get too hot for most insects to survive so they'll abandon the site. Good luck with your composting project.
