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.

    Thanks guys for all of your feedback...the idea of a box fan sounds great!!!

    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 with a ceiling fan on my covered porch and there are three fans but they only circle the middle one whether it's off or on. I've tried everything. Lavender plants lavendat oils, cleaning everything with pinesol ,bags of water , fly strips. Even the electric fly swatter They won't go away 😳😩

    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.

    I just noticed that I have a fly problem. I just happened to look out the window and noticed all these "dots" on my grill cover. I went outside to investigate and the grill cover was covered in flies. I went to swat at one and it didn't move. I swatted at some others and they didn't move either! I looked around the yard some more and I counted at least 20 from the patio, to the grill to the side of the house. I killed the ones I could reach. It was so weird how they didn't even move at all. I have never been able to kill a fly no matter how hard I tried - they are usually just too quick. This is really strange. Anyone have any idea why these flies are here and why they are not moving?

    Wow! Kinda creepy how its happening to so many people! I've lived in this house 16 years, patio covered last 7 years. This is the FIRST time I've had this cluster of small flies show up every day this Spring, flying in circles, never lighting on anything I can see, for just the hours in middle of day. They buzz around 3-4 ft off the ground. I've put up fly strips and water traps....without catching a one!!?? I've washed and disinfected my cement pation, made sure the freezer it working well and clean, (it is), and there are no leaks, (there aren't). Put a fan on a pole out there and that works well enough while we're sitting at the patio table. This is strange, right? Never happened in the past.

    I have a screened patio and about a week ago, flies started showing up. I have no visible opening anywhere. I have lots of plants on the patio and a metal garbage can that is always closed. I also do not put anything perishable in the garbage can. I have no idea where the flies are coming from. My pest control man came out yesterday and sprayed, but the flies returned with a vengeance. The flies have now quadrupled. What can I do?

    It is good that some of us examine nature at its best. I notice them on my entry door on the concrete this morning. God's creation is wonderful I must say. We do know they are attracted to vibration and light from the morning dawn of the day. They do act very strange almost like they are lazy but I think it is more to them matting cycles in time. Go look at the life cycle of a fly it will amaze you. Heat is very needed for them to move freely. I notice this morning it is very cool and they are disoriented big time.

    I habe the same problem. The circle around my covered porch and carport. My neighbor has the same setup and he has no flies. I used a bug fogger, the kind with a propane tank attached mainly used to kill mosquitos. It does kill and disperse the fly pack for a short period. But they always reappear within a couple weeks.

    And if you google "hover flies" you can learn more. Basically they don't harm anyone, they don't land on you, they don't bite but they are a visual nuisance. So far, I've found nothing that permanently gets rid of them.

    I'm having the same problem with the flies we swat and kill 20 andand 30 more come back we bought fly strips and didn't catch even 1. I heard mosquitoes are bad this year because of the wet winter maybe that helped the flies too?
