We found this fly-looking bug crawling on Cosmo today - I think I've found one once before. We were able to get it off but are worried there might be more? We asked around and people have suggested it could be a horse fly or a pigeon louse fly. We have been using frontline plus, but does this protect him against this bug? Should we be concerned? I am thinking of switching to advantix because it protects against stable flies - but is this bug a stable fly?
