Problem with little flies

I am on relatively small property that doesn't have any sources of standing water.
I don't have too many mosquitoes but I do have a lot of very small black flies that swarm around and are really vicious.
They are actually the worst. They bite, they attack everyone and swarm.

I tried using Cyzmic CS, Talstar P and Cutter.
they all work for 2-4 days....maybe 7-10 at the best....but never anywhere close to their advertised 30-60 days.

I wonder if there is something more effective and persistent.

thanks!

 

You generally have to find the food source which is sustaining them in order to make any long term gains.

 

I do have lot of plants and flowers..... Not sure what else they feed on....I made sure to eliminate all water / moisture.
Maybe at least you guys can make recommendations on most effective chemicals and then also best way to apply.
I heard to spray under the leaves and also to focus on shaded areas.

 

Take specimens to the local county extension agent for a proper and objective identification. Especially with flying insects, knowing what they are will lead us to their habitat, food sources, treatment options, etc.

The treatment you are performing is a mosquito treatment, but may do nothing for the flies in question. I don’t think it will be a question of different insecticides as you are using professional grade stuff. Cyzmic is a micro-encapsulated pyrethroid and lasts as long and longer than anything out there. We used that particular active ingredient a lot.

Fly species are so varied in behavior, biology, habitat that what works for one specie is a waste of time and resources on another specie. It is paramount to know what specie these guys are. Hope this helps. Keep us posted.

 

PAbugman - thanks for the info....will want to do this, but first need to figure out how to catch them....I can barely see them and yet it feels like there are hundreds of them.
when I step outside the first 5-10 seconds are nice and then, they appear and I can just hear them buzzing around my face and my head.....barely visible but they actually keep flying right into my face and my body....anyone wants to be outside needs to apply DEET all over...I mean, any uncovered area and they will just fly into that spot..and they just keep buzzing around...like they never actually land on you, so it is hard to kill them.

 

so finally got a decent picture of one of those annoying flies..... still not sure this is the only type that is guilty of causing me all the pain and all the bites all over my legs.... but anyhow...
At least I can confirm that I barely see mosquitoes....

 

by the way....this thing is small....I mean very small.... like 1/8th of inch. the pic above is cropped

 

I’ve done some searches and still can’t figure out what they are. Take the picture (and a specimen if possible) to a local source for ID, such as a county extension agent. There are so many species of outdoor flies and they vary so much by region that I’m thinking that a local person could ID these guys quickly.

I’ll keep trying from here. Let us know what you find out. I’m curious.

It does look like a biting type of fly though.
