    This is very informative but what I want to know is why when I actually do manage to hit a fly while its in the air and send it careening into the wall, how is the fly still alive and buzzing back around moments later? I know it has a lot to do with the mass of the fly being significantly less and perhaps the effect this has on its inertia and momentum and im sure the surface area of the impact the force is imparted upon and the impulse of the surface cushioning the blow and perhaps air resistance also play factors in a fly’s survival or not but it’d be interesting to have a full breakdown on the physics of the forces imparted to a fly from an ariel collision with a human swatting them. Obviously the full force of the human hand isn’t imparted onto the fly because when the fly is caught between the hand and another surface it doesn’t walk away from it but fly is that exactly. Like I said above I have a few different predictions on the factors at play but don’t know for certain and this channel is really good about presenting these lesser known facts and im curious if anyone can answer this question more definitively?

    They forgot to mention flies and most other small flying insects are so light the wind created by you swinging that magazine at them is enough to blow them out of the way before the magazine can actually squash them. Which is why fly swatters have holes and why a magazine or newspaper works better when rolled up. I also think curved mirrored surfaces might confuse them because they are easier to hit whilst in flight if you use a spoon.

    I've developed a technique to hold flies in the fly with my hand, with an accuracy of about 60/70%. You basically need to let the fly land somewhere, get close enough (considering your own agility and biomechanics) and swing your hand as fast as you can, not where the fly is, but where you predict it will be by the time your hand arrives to that area. With practice you learn better to predict their movements, they are quite predictable and they don't change the evasive move once they chose it.

    It's easier to just slowly get a few cm above them and then slapping your hand down formed like a cup. This way we are taking advantage of their super fast reflexes. By moving slowly above them they don't recognize it as a threat. Thus we are applying evolutionary pressure either to make them smarter or slower in their reaction time.

    Actually I've figured out a way to get around this, you just keep swatting at them in their general direction without trying to hit them. If they try to land swat at them again. If you keep this up they will quickly just burnout and literally fall out of the sky. This is an especially good strategy if you're dealing with a lot of flies, say if someone leaves the door open or if you're in a room with a lot of breakable items.

I have succeeded in catching more than one in a single swipe. Based on their wing shape and center of gravity I think they take off more like a helo than a plane also the approach from the rear cuts down on their line of site and notice that something is coming.

    Another important thing about killing flies is that they jump straight up if they are on a flat surface before taking off in either direction so if you clap your hands together about 2 inches above the fly you are almost guaranteed to get it first try. I learned that little physics lesson in band class because they were pumping the septic tank one day during school and there were 100s of flies that decided to make their way into our classroom. My instructor told us about it and we had a contest to see who could kill the most flies for an extra 100 to average into our final grade where everyone else that participated only got an extra 50 points. I killed 49 flies in about an hour. The winner got like 63. It was a tough competition. lol

    One trick that often works for me is to wait until the fly is somewhat near the ground, and then while above the fly, flick the fly swatter toward the ground. This creates a gust of wind that stuns the fly and knocks it onto the ground, and then I can deliver the killing blow. I also bring my cat into the room so that he can use his superior cat senses to keep track of the fly. I can find the fly based on where my cat is looking

    The best trick for whacking a fly with a standard swatter is to swing it so the edge of the swatter leads the way. Then at moment of contact roll your wrist to the flat of the swatter. It will make for a faster incursion with far less of an air wall that would push the fly out of the way.

    In my experience, flies tend to jump forward when taking off. Here's how I catch them: 1- Hand extended (as if to shake somebody else's hand). 2- Fingers touching (so there are no gaps between them) 3- Slowly make a slightly concave shape (this will reduce the time it takes for you to trap the fly) 4- Start moving the hand closer to the fly, perpendicular to the surface, very slowly and calmly. (If done right, the fly shouldn't be spooked) 5- Once the hand is within striking distance, lunge like a snake. The fly should jump towards your palm upon getting spooked, you should be able to feel the impact. 6- Now it's a matter of trapping the fly on your palm, closing it immediately and without leaving any gaps between fingers, so the fly can't escape. 7- Give it a good shake, as if you were about to throw a die, if the fly is in there, you'll feel it bouncing around. 8- Release the dizzy fly. It probably won't come back to bother you again. I've found that flies tend to "learn their lesson" after being caught and shaken like this. They'll probably go bother someone else (someone who doesn't have fly catching skills). This skill is specially useful in summer.

    I lived next to a horse corral one summer and came up with a nearly perfect approach to killing flies. All you need is a large rubber band and a little practice. When you shoot the rubber band at them it travels to fast for them to get out of the way. It's better if you can get to within a couple inches before shooting, but with practice you can also get them on the ceiling.

    My auntie taught me how to catch flies, she was a MASTER. You need to catch them from the rear, moving in a slug like speed first and than catch/smash it suddenly when close enough. Being very slow, fly can't see you movement. You get them from behind, because when fly takes off, in a split of a second it turns backwards. It really does work!

    Better options: 1-the commercially available salt gun. 2-soapy water on a spray bottle (set to stream, not spray) Both of the above attack the fly with fast invisible proyectiles that will not make a disgusting mess. The second type even hinders their strength by choosing their wigns with a heavy soapy goo that will ground them instantly.

    Airflow is a key factor as well. Moving a solid plate or a hand with finger closed together will drive the air away from the front face of the motion. And Fly is such a tiny insect that it could make use of such air flow to flee. Use a swat with meshes will be much easier to hit flies than a solid one.

    When a lad in the late 50s with tadpoles and young frogs to feed, I had good success by hand, a quick sweep from behind, a little above, so they took off into your hand. There seems to be a general consensus earlier of slow approach so they are complacent, and quick finish. Now I am slower (I even drive slower, LOL) a swat still works with slow approach and quick finish, but sometimes, if the path is clear, a super-fast sweep from a distance can work.

    Interestingly, each wing on a housefly is controlled by 7 individual muscles, which are each controlled by a single neuron. Each muscle can be either fully contracted or fully relaxed, the only control the fly has is over which muscles contract and for how long. IIRC about 1/5 of all of the neurons in a fly are in the halteres, doing sensing and feedback to the wing neurons to compensate for atmospheric conditions. Imagine if your hands had the ability to grasp things without even having to talk to your spine, based on the input from hairs on your palms that can detect when anything down to the size of a grain of sand lands on them, and that's about how flies manage to stabilize themselves.

    How to swat a fly. First of all the fly has to land and stay sitting some place where you can do this, ideally a countertop or other flat surface with enough room on either side of the fly. Position both hands on either side of the fly about 6 in away, most of the time the fly will fly away at this point providing it doesn't, bring both hands together rapidly as though you were going to clap. Right before reaching the fly lift your hands up about 1 or 2 in then smack them together. Ideally the fly should be right between your hands and will get smacked. This is because the fly having to try to dodge two obstacles won't be able to get away. The reason you lift your hands at the last second is because the fly jumps straight up and you want to catch him smack in the middle of your palm. The reason this works is because if you approach a fly from one direction it will fly in the other automatically without thinking about it. By presenting the fly with two obstacles coming at it at the same time the fly has to think for a brief instant and it usually flies straight up. This positions it directly between your two incoming hands hence lifting at the last second your hands up an inch or so

    When flies keep getting into the house, first thing I do is see if opening the front door up will get them to wise up and leave (usually doesn't work). If not, I just wait for them to land, slowly get up close to them, swat, wait again, and keep at it 'till they finally die. I also try to corner them into a small room and then close the doors when they land, and if I can't do that then I'll turn off all the lights except in one area, pretty much all flies seek out the light instinctively, even when I'm going after them. Eventually those little (and sometimes not-so-little) bugs get too tired or cocky and that gives me the extra fractions of a second I need to finally hit them down.

    Hmm catching in flight them is tricky depending on the species, temperature and lighting I think my success rate varies from 15 to 30% per attempt. What seems to help is approaching it slowly at first and then a sudden quick movement to grab them preferably in the direction they are flying. To exterminate them in the house I prefer the electrical ones instead of splatting them on the wall. As a bonus you can also catch flying ones with it easily, bit of a nuisance that some larger flies only seem to be stunned by it but they are often on the ground long enough to get them with a vacuum cleaner a bit later (or my cat that sees them as toys to use for a bit during which they'll certainly die).

    I always thought it had to do with air currents-- if you're swatting with a flat surface with no holes (like your hand) as long as the fly is flying the air rushing out from under your hand carries it away. However, when using a mesh flyswatter or swatting one on a screen door, the air can travel through the swatter or through the door and will therefore not help push the fly away. Dunno how much that is a factor, though.

    Over 50 yrs ago my DH taught me *"The Trick Of How To Kill Flies!"* As flies *ALWAYS* spring _"UPWARD"_ while "taking off," the trick is to S-L-O-W-L-Y bring both (parallel) hands into a *"right-angle to the fly's stance"* position 3-6 inches "directly above" the position of the fly. ("Directly above" refers to the fly's points of reference, _NOT_ TO YOURS!) That distance is dependent on the ambient temperature (I'll explain that in a moment, honestly!☆) Also, analyze the angle of the fly's stance in relation to the surface upon which it is standing, as you want the fly's initial spring to take it DIRECTLY BETWEEN your palms. When perfectly positioned, DON'T EVEN THINK ABOUT THE FLY, JUST ABRUPTLY *SLAP* YOUR HANDS TOGETHER! *THE FLY WILL, VERY OBLIGINGLY, LEAP DIRECTLY BETWEEN YOUR QUICKLY CLOSING HANDS - AND BE CRUSHED!* ☆The warmer the air, the *more lively a fly will be,* and his initial "spring!" will be significantly higher in warmer air. Also, if the fly is standing on a sloping surface, his initial spring WON'T be taken in a "right-angle to gravity" direction, as one might suppose, but rather he will spring almost _DIRECTLY_ in a 90° angle to the surface he's standing on, instead. (Watch a couple of "startled" flies take off, if you need verification of this; it might surprise you!) This method can have a _VERY_ *HIGH success rate,* and individual success *WILL IMPROVE* with practice & experience! Nowadays, my DH "gets his beast" about 90-95% of first tries these days, but then, at the age of 78 he _HAS_ slowed down a bit since his younger years (who hasn't?) He USED to get them about 98% of the time *on his 1st try!* I've never been THAT good at it, but it still works better than a "fly swatter" for me. However, "to each his own," as "they" say! Whatever method you attempt, please remember to dispose of "the carcass" properly, then WASH YOUR HANDS, *AND USE SOAP.* *HAPPY HUNTING, FRIENDS!* 👏

    Their high flicker response can work against them. I hold me hands 3 inches apart ready to clap. Then I move my hands slowly over the top of the fly, and parallel to the fly’s body, stopping about 2-3 inches above the fly. The slow movement doesn’t alarm it. Then I clap my hands. The fly gets airborne generally straight up and right into the clapping. Style point: watch a fly for a minute. They have 2 modes. A fly will tend to remain airborne, and land briefly, returning to flight. But after a bit they tend to land for longer periods. If it does take off, quite often a short hop and loiter on the surface. Slow approach and I get 70% kill rate.
