Why are flies gathering on my covered patio in the same spot?

Hi Hometalk Peeps...I have a problem on our back covered patio. Every year in the same spot we get tons of flies ....We put up one of those fly traps before that traps them in a plastic bag filled with water....Problem is the same trap that kills them actually attracts them....I just want to know why they are always there in the first place. Do they like covered patios?

    Is there a moist area around your patio? Do you keep your trash cans near there?

    There are daisy plants that flies LOVE. Do you have plants near by that could be attracting them?

    Hi guys, thanks so much for replying to my question. @Barbara Thomas we do not have daisys around. In fact I have a bunch of lavender plants in pots on the back porch because I read that flies no not like the smell of them. Unfortunately it does not work. @ @Douglas Hunt well we have our Dogs water dish in the area. Although I never saw any flies near his water bowl. We have a raised TREX deck, maybe it is moist underneath that...not sure.....

    Sorry I don't know what could be the problem. However, Ortho makes a spray you attach to your hose and it kills all bugs, spiders, ticks. Maybe there's something like that available. When I'm stumped I go to Lowes. LOL good luck!

    @Christine @ Little Brags that has to be soo annoying! I feel for you! I hate it when we have one or 2 in the house and for some reason they keep flying in a circle..around and around and around..and I am not good at getting them unless they land somewhere. Wow, I hope someone has an answer. Maybe a spray would get the existing ones, but then more would come in, so I am thinking that is not the solution. There is some fly behavior that is attracting them. I am really curious, so keep asking, like your county extension service? Arboretum? maybe they can direct you to someone who knows. I would like to know also.

    You need to move your fly traps away from the area. Much like those light zappers. if you place them to close to where you sit the bugs feast on you before they get zapped. Flies are no different. Put any attractant and trap away from the area in which you want to enjoy.

    Has something been spilled there? Turn on a box fan when you want to sit out there and the flies won't bother you.

    Sorry to chime in late, but incase anyone else who reads this is interested.... I heard that they like the low pressure of air that a covered patio/porch have. I also have a covered patio and there really isn't much you can do unless you buy plants they don't like, change the environment (fans) or enclose it with those bug netting curtains.

      @Amanda I am thinking the same thing, which is why I suggested the county extension or something like that. it must have to do with air or air pattern ...which is why I was wondering why they just fly in a circle in a certain area.. in the house, in one place, don't they get tired or dizzy?

    Oh your welcome. It seems like nothing gets rid of those pesky things. ;D Alternative methods I heard worked were filling a ziploc bag with water and hanging them around your patio, or a few old cds/dvds hanging around. The logic behind that is that their eyes have many individual facets, each representing a separate light-detecting unit. And apparently the water bags, or cds really screw with their vision. I haven't tried any of these methods, because I didn't want to hang little bags of water around, and just decided to custom (curtain) my patio with outdoor mosquito/bug netting.

    I just "searched" asking why do flies fly in a circle inmy house, or patio? Lots of interesting info, but the circling is not conclusive, but you may find some info on why there are so many on the patio etc. lots to think about.

    I tried the ziploc bag filled with water and it seemed to attract more. The flies invited their friends to come hang out by their new pool. I've had pest control companies out and no one knows why they show up every year, with the warm temps. Drives me crazy.

    I still say, a bug zapper & a 6 pack of Pepsi = great entertainment. :-) try the fans first....then if that don't work, search the internet for plants that flies do not like...if neither of them work, try the first one...bug zapper.

    I have the same problem on a covered back deck! Same spot daily, we zap them with electric fly swater and new ones return!

    It has to do with the lack of moving air i have been told. I visited the Clorox plant one time and they have a testing room with flies and fly spray. They have the bait on poles and they noticed the flys would walk up the poles because basically they are lazy and dont want to use their wings, so they had to grease the poles to make them fly. I am thinking it might be something like that, they like the still air of the patio. I put in a small fan to blow across my porch, one of those little 6 inch ones and they don't come in as long as it is running. I also have a horse corral fly trap about 10 yards away, but they are stil there. EVERY. SINGLE. YEAR! The only thing that works is the fan. We also had a mist hose one year and they definitely don't like getting wet.
