Steve from Hingham, Wi writes,

We have flies at our cabin in northern Wisconsin. Will CB PCO work on them? They keep appearing all winter....

I vacuum them up and the next morning there are dozens more. Are these cluster flies? What's the best prevention?


It sounds like you may have cluster flies. The CB PCO Fogger will kill any flies that are exposed at the time the fogger is released but it will not control those flies that prefer to stay hidden inaccessible areas. Here is an article that will give you a little bit more information on cluster flies and cluster fly control methods: How to get rid of cluster flies
