Well I should have listened to my first instinct and not of purchased this. I have had this on all day and all night,It has cost me hours of wasted time. I moved it literally twenty times all over in different places in my back yard. Even up high and low. Then I even hanged smelly food on the outside grits to attract all the flies that are annoying me and my pets. NOTHING WORKED!!! It literally killed only three flies in a twenty four hour period. There is nothing that I could of done that I did not try to get this to work. Not to mention the power cord is ridiculous how short it is. DO NOT LISTEN TO THE HIGH REVIEWS. DO NOT BELIEVE THEM. I AM RETURNING. And once again a company with a cheap plastic expensive product that is a piece of CRAP.
