I see that some are supposed to work great but they need to be kept outside at least 20 feet from doors or windows because they smell so bad.

Any products that can be put near front door or window and don't smell really bad?

I know the odor is what attracts the flies but tenants will get rid of the bag fly catchers if they smell that bad.

And i see that the sticky strips are not that great.

So what to use???

Check the farm/ranch stores for their options. They might have some good ones that people use to keep flies away from their stables.

Another thing, around here, restaurants put fly repellent around their outdoor seating. But it's not chemical, but visual. It messes with the fly's vision, and confuses it or makes it sense danger, so it avoids it. Different places use different methods, but they're all ultimately a combination of constant movement plus reflection. So, it might be baggies of water suspended on a string, or cds suspended on a string, or these teardrop-shaped glass vessels full of water that get suspended.

Dino,

The stuff I bought at Rural King was putrid beyond belief. I wanted something for inside but QUICKLY moved it outside. But the flies which were "bugging me" (see what I did there ;) were inside, not 20 feet away.

A little apple shaped jar with orange soda pop attracted a caught many of the little buggers.

The horse barn thing works - ZIp lock bags with water and pennies, hanging around the edges.

For inside the house?

Screens and a good, old-fashioned fly swatter.

Cats inside for catching sky raisins.

BTW if you have Japanese Beetle bags, change them EVERY week. Especially in high infestation areas. They stink especially after a rain or two. The lure smells kind of like chrysanthemums.

I have a electric racket that I turn on at night with all the other lights off and they fly right into it.

I just hang a electric bug zapper. Flies come into it even in the daylight.

The best way to use bug zappers is to gift them to neighbors.

They work great but they also attract more pests with the light at night.
