I have a large infestation of cluster flies. Will this product kill the flies, providing I give all the cracks a liberal spaying?
No, Demon Max is not labeled for cluster flies. We would recommend using Demand CS. This product can be used indoors and outdoors for fly control. The rate is 0.4 fl oz per gallon of water. The residual indoors is 90 days and 30 days outdoors. Keep in mind that we can only ship within the US.
