Orrrrrrrrrr, and hear me out......

You build a tiny replica house so that the fly isn't homeless. Then he'll leave you alone.

My go-to trick is to get a water bottle that sprays an aerosolized mist and just spritz the area liberally.

Most insects(?) can't fly with wet wings and become easy to handle.

There are these particularly annoying flies that I encountered in Florida. When they land you can blow on them which will cause them to hunker down and brace against the wind leaving them vulnerable to a swat

I didn't know I was supposed to get a crushing hand. I only got these two flimsy ones.

You could also just shoo them outside. I'd prefer to not have fly guts all over my hands, and I don't really have the need to kill every fly I see.

I just blow em away with this bad boy. Best 50 bucks I ever spent. So much entertainment.

You talk like someone who doesn't have carnivorous plants.

I never kill flies. I just feel bad. I do, however, trap them in a glass beaker and release them outside. It's super-easy, you just go slow. Once they settle, slowly lower the glass over them. Then slide a bit of card between the glass and the surface and transport them outside.

Honestly, I have no idea why I do this. Maybe I subconsciously hope these small acts will balance my karma and somehow negate my illegal IPTV subscription.

Move slow enough too and a fly won't percieve you moving very well. Benn Jordan's video about what the world sounds like to different animals taught me that. Flies basically live in constant bullet time.

Any kind of spray you have lying around should make their wings too laden to fly. Simple Green, Windex, Axe Body Spray, etc. Could probably just be a spray bottle with water too.

Then you can do what you will with them.

Also, their night vision is terrible.

Man... I'm way to tired. I red your post as "Houses" (without the fly part) and I was so confused why you want to catch a house and if this is some kind of surreal post. Nope, just can't read, houses can't jump.

I like to get a dishcloth and whip them.

clapping with both hands works too

Can confirm this works. I used to astound all of the waitresses when I was a dishwasher because I could swat a fly every time without fail.
