How to keep flies out of my garage?

My house is a new construction and the garage is spotless. For some strange reason, swarm of flies just buzz by wheneven I open my garage door. They seem to be attracted to anything inside the garage such as car cleaning supplies, some boxes and even the garden hose. Any suggestions? Thanks!

 

Where you storing your trash cans?
Is there a dumpster near by that everyone uses?
Anyone have livestock in the area?

 

The trash cans are in the outdoor area next to the garage. The cans are new, covered and clean. The flies are not attracted to them as far as I can tell and there's no apparent odor from the trash.

I'm in a new community and there's some construction going on in the area. There used to be a open dumpster for construction waste a couple of houses down from me but it is no longer there.

No livestock.

 

Identifying the fly specie will be a help as it will tell us what they eat, what/where their preferred harborage is, control strategy, etc.

Flies are also very much attracted to certain colors and I believe that white and yellow are two of them.

Quikstrike fly abatement strips are a good bait for flies. Don’t think they would work on horseflies, deerflies, etc as they feed on mammals. Available on-line and in hardware/feed stores.

Take some flies to a county extension agent to get them identified. That will point us in a productive direction to understand these guys. You may have flies out there that we don’t have here in the northeast so a local ID can be very helpful. Keep us posted with info and questions.

 

PAbugman nailed all my suggestions.

It may also be worth noting if the local ministry has released that specific bread of insect to control another.
Locally, they had done that in the past, which resulted in the released species being more of a pest then the one they where trying to control.
A couple years ago, we where infested with friendly flies (also known as house flies locally). Another year, it was lady bugs.

 

We had a fly problem years ago that was beyond description (found out they were dumping sewer grease in a nearby field...) and what I did was hang a bug zapper inside the garage - it did kill some of them, I would have to sweep a pile out every morning. That doesn't solve the problem, I know, but might help until you do.

 

They look like blow flies to me (red eyes, green metallic bodies, wings folded away from their bodies, no sound when flying). They seem to be attracted to anything. Now I can't even open my front door for more than a minute without having some of them getting into my house. Any suggestions on how to control them? Thanks!

 

You have to find out where they're coming from - my problem persisted until we stumbled on the guy dumping in the field. Once he stopped, the flies went away.

 

The metallic flies, blue or green like to breed in decomposing matter, decaying meat, etc. Normally I’d suggest looking for a dead squirrel or something in garage attic ,etc but I’m liking mitch’s suggestion even more as to something in your surrounding environment.

Are your neighbors experiencing this fly activity too?

 

Hey, I guess best is to find out what the source is and then do something about it. However, if the source is unfindable or unfixable then a bug zapper or bug trap would do the trick. If you need more info please let me know. How big is your garage?
