At a 70% savings – snag the Pic Fly Ribbon Bug and Insect Catcher – pack of 4 for $3.60. They have a 4-star rating. I could’ve used these a couple weeks ago. My house was hit by cluster flies. No exaggeration – there had to be 100 of these cluster flies behind my blinds in the living room, on the ceiling, in mine and my son’s bedrooms. We ended up sucking up what we could – in the vacuum. The others – we trapped between the screen and the windows…where they died.
